Frequently Asked Questions - GSL 2 Professional BOSCH

What is the battery life of the GSL 2 Professional floor laser?

With alkaline batteries (4x LR06), the battery life is approximately 15 hours. With a Bosch 1.3 Ah Lithium-ion battery, it is also 15 hours, and 25 hours with the 1.5 Ah battery.

How do I align the two laser lines?

Turn the height adjustment knob (9) until the two lines overlap at the reference point (approx. 50 cm in front of the device). If they do not overlap, move the device to a surface closer in height.

Can I use the remote control to turn off the device?

No, the remote control cannot turn off the floor laser. You must use the On/Off switch (8) to turn it off. The remote control is only used to control rotation (fast, slow, or stepwise).

What should I do if the laser flashes after switching on?

Flashing indicates that the device is outside the self-leveling range (±4°). Place the device on a more horizontal surface; once within range, the lines will stay permanently lit.

What is the leveling accuracy of the GSL 2?

The accuracy is ±0.3 mm/m. This means that at 10 meters, the maximum deviation is 3 mm.

How do I clean the device?

Use a soft, damp cloth. Never immerse the device in water and do not use detergents or solvents. Clean the areas near the laser outlet regularly to remove dust.

Can I use rechargeable batteries?

Yes, the device accepts Bosch Lithium-ion batteries (10.8 V) as well as standard alkaline batteries. For batteries, use only recommended Bosch chargers.

The device turns off by itself after 30 minutes, is this normal?

Yes, the automatic shut-off after 30 minutes of inactivity is a power-saving feature. To restart, toggle the On/Off switch to 'Off' then back to 'On'. With the remote control (Set), you can wake it by pressing a button.

How do I interpret the two laser lines on the floor?

If the two lines overlap, the surface is at the same height as the reference point. If they are separated or interrupted, there is a height difference. Use the laser target plate (10) to measure the deviation in millimeters.

What to do in case of a malfunction or defect?

Entrust repairs exclusively to an authorized Bosch after-sales service. Do not open the device yourself. To identify your device, refer to the 10-digit article number on the rating plate.

All instructions must be read and observed in order to work safely with the measuring tool. Never make warning signs on the measuring tool unrecognisable. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN GIVING IT TO A THIRD PARTY.

• Caution - The use of other operating or adjusting equipment or the application of other processing methods than those mentioned here can lead to dangerous radiation exposure. The measuring tool is provided with two warning labels (each marked with number 2 in the representation of the measuring tool on the graphics page).

If the text of the warning labels is not in your national language, stick the provided warning labels in your national language over it before operating for the first time.

Do not direct the laser beam at persons or animals and do not look into the laser beam yourself. This measuring tool generates laser radiation from class 3R according to IEC 60825-1. Looking directly into the laser beam - even from a greater distance can cause damages to the eyes.

If laser radiation strikes your eye, you must deliberately close your eyes and immediately turn your head away from the beam. Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation. - Do not use the laser viewing glasses as sun glasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce colour perception. Do not make any modifications to the laser equipment. Have the measuring tool repaired only through qualified specialists using original spare parts. This ensures that the safety of the measuring tool is maintained. - Avoid reflection of the laser beam on smooth surfaces such as windows or mirrors. A reflected laser beam can also cause damage to the eye. The measuring tool should be operated only by persons that are familiar with the handling of laser devices. According to EN 60825-1, this includes, among other things, the knowledge about the biological effects of the laser to the eyes and the skin as well as the correct usage of laser protection devices in order to avoid dangers. Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases or dusts. Sparks can be created in the measuring tool which may ignite the dust or fumes. Always set up the measuring tool in such a manner that the laser beams run far above or below eye level. This ensures that damage to the eyes will not occur. Mark the area in which the measuring tool is being used with suitable laser warning labels. This prevents persons not involved from accessing the danger area. Do not store the measuring tool at locations to which unauthorised persons have access. Persons not familiar with the operation of the measuring tool can cause harm to themselves and to others. When using a class 3R measuring tool, observe possible national regulations. Non-observation of these regulations can lead to injury. Make sure that the area of laser radiation is monitored or shielded. The limitation of laser radiation to controlled areas prevents eye damage to persons not involved. Before any work on the measuring tool itself (e.g. assembling, maintenance, etc.) as well as when transporting and storing, remove the battery pack or the batteries from the measuring tool. Danger of injury when accidentally actuating the On/Off switch. Do not open the battery pack. Danger of short-circuiting.

Protect the battery pack against heat, e.g., against continuous intense sunlight, fire, water, and moisture. Danger of explosion.

When the battery pack is not in use, keep it away from other metal objects such as paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. Under abusive conditions, liquid may be ejected from the battery pack; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery pack may cause irritation or burns. In case of damage and improper use of the battery pack, vapours may be emitted. Provide fresh air and seek medical help in case of complaints. The vapours can irritate the respiratory system. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. Use the battery pack only in conjunction with your Bosch measuring tool. This measure alone protects the battery pack against dangerous overload. Use only original Bosch battery packs with the voltage listed on the nameplate of your measuring tool. When using other battery packs, e.g. imitations, reconditioned battery packs or other brands, there is danger of injury as well as property damage through exploding battery packs.

Keep the measuring tool and the laser target plate 10 away from cardiac pacemakers. The magnets of the measuring tool and laser target plate generate a field that can impair the function of cardiac pacemakers.

• Keep the measuring tool and the laser target plate 10 away from magnetic data media and magnetically sensitive equipment. The effect of the magnets of the measuring tool and laser target plate can lead to irreversible data loss.

Remote Control (GSL 2 Set)

Read and observe all instructions. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

Have the remote control repaired only through a qualified repair person and only using identical replacement parts. This will ensure that the functionality of the remote control is maintained. Do not operate the remote control in explosive atmospheres, such as in the presence of flammable liquids, gases or dusts. Sparks can be created in the remote control which may ignite the dust or fumes.

Assembly

Power Supply of the Surface Laser

The measuring tool can either be operated with commercially available batteries or with a Bosch lithium ion battery pack.

Operation with Batteries (see figure B)

Alkali-manganese batteries are recommended for the measuring tool.

For installation and removal of the batteries, the measuring tool's height adjustment must be set to the lowest position. For this, turn the thumbwheel for height adjustment 9 in anticlockwise direction to the stop.

To open the battery lid 7, press on the latch 6 and fold the battery lid up. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery lid.

Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity.

• Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and self-discharge.

Operation with Battery Pack (see figure C)

Use only original Bosch lithium ion battery packs with the voltage listed on the nameplate of your measuring tool. Using other battery packs can lead to injuries and pose a fire hazard.

Note: Use of battery packs not suitable for the measuring tool can lead to malfunctions of or cause damage to the measuring tool.

Note: The battery pack is supplied partially charged. To ensure full capacity of the battery pack, completely charge the battery pack in the battery charger before using for the first time.

Use only the battery chargers listed on the accessories page. Only these battery chargers are matched to the lithium-ion battery pack that can be used in your measuring tool.

The Lithium-lon battery pack can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery pack.

The battery pack is equipped with an NTC temperature control that allows charging only within a temperature range of between 0°C and 45°C. This ensures a long battery pack service life.

To install or remove the battery pack 23, the measuring tool's height adjustment must be set to the lowest position. To do this, turn the thumbwheel for height adjustment 9 anticlockwise to the stop.

To insert the battery pack 23, press the latch 6 and fold the battery lid 7 up. Slide the charged battery pack completely into the battery compartment and close the battery lid.

Operation with a 1.5 Ah battery pack: To shut the battery lid 7, the foam damper on the inside of the battery lid must be removed.

To remove the battery pack 23, press the latch 6 and fold the battery lid 7 up. Pull the battery pack out of the battery compartment.

Power Supply of the Remote Control (GSL 2 Set)

Using alkali-manganese batteries is recommended for operation of the remote control.

To open the battery lid 20, press the latch 21 and remove the battery lid. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery lid.

Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity.

• Remove the batteries from the remote control when not using it for longer periods. When storing for longer periods, the batteries can corrode and discharge themselves.

Operation

Starting Operation of the Surface Laser

Protect the measuring tool against moisture and direct sunlight. Do not subject the measuring tool to extreme temperatures or variations in temperature. For example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired. Avoid hard knocks to the measuring tool or dropping it. Damaging the measuring tool can cause accuracy to be

compromised. Following a hard knock or fall, carry out a check by comparing the laser lines or plumb beams with a known horizontal or vertical reference line or verified perpendicular points.

• Switch the measuring tool off during transport. When switching off, the levelling unit, which can be damaged in case of intense movement, is locked.

Setting Up the Measuring Tool

Set up the measuring tool on the floor surface to be checked, ensuring that it is firmly positioned.

The levelling accuracy can be influenced through the ambient temperature. Especially temperature differences occurring from the ground upward can deflect the laser beam. As the thermal layering is greatest at ground level, the measuring tool should always be set up in the centre of the floor surface to be checked.

Switching On and Off

To switch on the measuring tool, slide the On/Off switch 8 to the "On" position. Immediately after switching on, the measuring tool sends laser beams out of the exit openings 1.

Do not direct the laser beam at persons or animals (especially not at their eye level), and do not stare into the laser beam yourself (not even from a distance).

To switch off the measuring tool, slide the On/Off switch 8 to the "Off" position. When switching off, the levelling unit is locked.

When the measuring tool is not moved or remote-controlled for approx. 30 minutes, it switches off automatically to save the batteries or the battery pack.

After switching off automatically, switch the measuring tool off via On/Off switch 8 and then on again, if required. GSL 2 Set: After switching off automatically, the measuring tool can be switched on again by pressing any button on the remote control.

Do not leave the switched-on measuring tool unattended and switch the measuring tool off after use. Other persons could be blinded by the laser beam.

When exceeding the maximum permitted operating temperature of 50°C, the measuring tool switches off to protect the laser diode. After cooling down, the measuring tool is ready for operation and can be switched on again.

Operation with battery pack: The "Electronic Cell Protection (ECP)" protects the lithium-ion battery pack against deep discharging. When the battery pack is discharged, the measuring tool is switched off by a protective circuit.

When the measuring tool switches off automatically due to a discharged battery pack, switch the measuring tool off with the On/Off switch 8. Charge the battery pack before switching the measuring tool on again. Otherwise, the battery pack could become damaged.

Allowing the Measuring Tool to Level In

After switching on, the levelling function automatically compensates irregularities within the self-levelling range of ±4°. The levelling is finished as soon as the laser beams do not move any more.

If the automatic levelling function is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 4° from the horizontal plane, the laser beams flash.

Set up the measuring tool in level position and wait for the self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the laser beams light up continuously.

In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled in again, yet, possibly to a different height when larger position changes are the case. Upon re-levelling, check if the two laser beams are aligned at the reference point (see "Aligning the Height of the Measuring Tool", page 16) in order to avoid vertical errors.

Aligning the Height of the Measuring Tool

The measuring tool generates two laser beams that can be seen on the floor surface in front of the measuring tool for distances beyond 50 cm. The beams must be brought into alignment at this reference point, where they can initially be seen on the floor surface. For this, turn the thumbwheel for height adjustment 9 clockwise or anticlockwise, until both laser beams overlap at the reference point and only one beam can be seen.

When the two laser beams cannot be aligned by turning the thumbwheel, the position of the measuring tool is significantly above or below the floor surface. Position the measuring tool at a different location on the floor surface with less height deviation and align the laser beams there.

Starting Operation of the Remote Control (GSL 2 Set)

Protect the remote control against moisture and direct sunlight. Do not subject the remote control to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the remote control to adjust to the ambient temperature before putting it into operation.

The remote control remains ready for operation as long as a battery with sufficient voltage is inserted.

The signals of the remote control should reach the reception lens 4 directly from the front and inclined from above. When the remote control cannot be pointed directly against a reception lens, the working range is reduced. By reflecting the signal (e.g. against walls), the working range can be improved, even for indirect signals.

Switching the measuring tool on via the remote control after automatic shut-off of the measuring tool is only possible when the On/Off switch 8 is still in the "On" position. Switching the measuring tool off with the remote control is not possible.

Measuring Procedure

Manual Rotation (GSL 2)

Rotate the upper part of the measuring tool to the location that you want to check. After rotating, wait until the measuring tool has levelled in again and the laser beams no longer move. Then, check if the laser beams run opaque.

Automatic Rotation (GSL 2 Set)

To check the surface, rotate the upper part of the measuring tool with the remote control. Manual rotation is not possible.

The following rotation modes are available:

Press button 19 to start fast, continuous rotation in clockwise direction. Pressing button 19 again ends the rotation.

Press button 14 to start fast, continuous rotation in anticlockwise direction. Pressing button 14 again ends the rotation.

Press button 18 to start slow, continuous rotation in clockwise direction. Pressing button 18 again ends the rotation.

Press button 15 to start slow, continuous rotation in anticlockwise direction. Pressing button 15 again ends the rotation.

Press button 17 for a single, brief rotation step in clockwise direction. For each further individual movement, press button 17 again.

Press button 16 for a single, brief rotation step in anticlockwise direction. For each further individual movement, press button 16 again.

Evaluating Measuring Results (see figures D - G)

The two laser beams indicate whether the surface is at the same height as the reference point (see "Aligning the Height of the Measuring Tool", page 16):

• All points at which both laser beams coincide exactly above each other are at the same height as the reference point.
• When two beams can be seen next to each other or when the laser beams are interrupted, the height of the floor surface deviates with respect to the reference point at this location.

To measure the deviation of the floor surface, position the laser target plate 10 at the location to be checked. Turn the laser target plate in such a manner that the left-hand laser beam coincides with the left reference line of the laser target plate. Slide the upper part of the laser target plate upward or downward, until the tip 11 of the laser target plate rests on the

location to be measured. The height deviation between the reference point and the measuring point can be read in mm via the position of the right-hand laser beam on the laser target plate.

When both laser beams run apart at a constant angle on the floor surface, the floor surface is inclined.

Working Advice

Pay attention that the complete width of the laser beams coincide exactly over each other. The width of the laser beams changes with the distance.

Transporting the Measuring Tool

The handle 3 can be used for easier transport of the measuring tool. Fold the handle up as required.

Laser Viewing Glasses (Accessory)

The laser viewing glasses filter out the ambient light. This makes the red light of the laser appear brighter for the eyes.

Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation. Do not use the laser viewing glasses as sun glasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce colour perception.

Recommendations for Optimal Handling of the Battery Pack

Protect the battery pack against moisture and water.

Store the battery pack only within a temperature range between 0°C and 50°C. As an example, do not leave the battery pack in the car in summer.

A significantly reduced working period after charging indicates that the battery pack is used and must be replaced.

Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning

Before any work on the measuring tool itself (e.g. assembling, maintenance, etc.) as well as when transporting and storing, remove the battery pack or the batteries from the measuring tool. Danger of injury when accidentally actuating the On/Off switch.

Store and transport the surface laser only in the supplied case.

Keep the surface laser and remote control clean at all times. Do not immerse the surface laser and remote control into water or other fluids.

Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or solvents.

Regularly clean the surfaces at the exit opening of the laser in particular, and pay attention to any fluff or fibres.

If the surface laser or remote control should fail despite the care taken in manufacture and testing, repair should be carried out by an authorised customer services agent for Bosch power tools. Do not open the surface laser and the remote control yourself.

In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the surface laser and remote control.

For repairs, only send in the surface laser in the case.

Transport

Do not expose the battery to high temperatures, e.g., to direct sunlight, fire, water, or moisture. There is a risk of explosion.

Keep unused batteries away from paper clips, coins, keys, nails, screws, or other small metal objects that could cause bridging of the contacts. Short-circuiting between battery contacts can lead to burns or fire. If used incorrectly, battery fluid may leak from the battery. Avoid contact with it. In case of accidental contact, rinse with water and seek medical attention. Battery fluid can cause skin irritation or burns. If the battery is damaged or used improperly, vapors may be emitted. Ensure fresh air flow and consult a doctor if you have complaints. Inhaling vapors can cause respiratory irritation. Charge batteries only with chargers recommended by the manufacturer. Charging with a charger designed for a different type of battery poses a risk of fire. Use the battery only in combination with your Bosch measuring tool. Only then can you prevent dangerous overloading of the battery. Use only original Bosch batteries with the voltage indicated on the nameplate of your measuring tool. Using other batteries, e.g., imitations, reconditioned batteries, or batteries of other brands, poses a risk of injury and material damage due to explosion.

Remove the measuring tool from the battery before storage. Magnetic fields from the measuring tool can affect the operation of pacemakers.

Before measuring, remove the implantable cardioverter-defibrillator. The measuring instrument creates a magnetic field that can affect the operation of the cardioverter-defibrillator.

Magnetic measuring tools and magnetic measuring devices can be affected by magnetic fields, which can lead to incorrect measurements or data loss.

Technical data

Working with the instrument

Putting the surface laser into operation

Protect the measuring instrument from direct sunlight. Do not expose the measuring instrument to extreme temperatures or temperature fluctuations. In particular, do not leave it in a car for a long time. In case of large temperature fluctuations, allow the measuring instrument to stabilize its temperature before starting to work with it. Extreme temperatures and temperature fluctuations can adversely affect the accuracy of the measuring instrument. Avoid heavy impacts and drops of the measuring instrument. After heavy external impacts, it is necessary to check the accuracy and calibration of the measuring instrument in an authorized service workshop. When transporting, switch off the measuring instrument. When switched off, the pendulum lock is activated, which can be damaged if the movement is excessive.

Setting up the measuring instrument

Set up the measuring instrument on a flat base on the surface to be measured.

The tilt of the instrument can be affected by the ambient temperature. In particular, temperature differences, which decrease with distance from the ground, can cause the laser beam to deviate. Since the largest temperature differences occur near the ground, the measuring instrument should always be set up on the surface to be measured.

Switching On/Off

To switch on the measuring instrument, press the on/off switch to the "On" position. Immediately after switching on, the measuring instrument emits laser beams through the opening for the laser beams 1.

Do not point the laser beam at people or animals (especially at eye level) and do not look into the laser beam (even from a distance).

To switch off the measuring instrument, move the on/off switch 8 to the "Off" position. The pendulum lock is then activated.

If you do not operate the measuring instrument for approx. 30 minutes and do not control it via the remote control, it switches off automatically to save battery power.

After automatic shutdown, switch off the measuring instrument using the on/off switch 8 and, if necessary, switch it on again.

GSL 2 Set: After automatic shutdown, the measuring instrument can be switched on again by pressing any button on the remote control.

Do not leave the switched-on measuring instrument unattended and switch it off after use. Other people could be blinded by the laser beam.

When the permissible operating temperature of 50°C is exceeded, the laser unit switches off. After cooling down, the measuring instrument is ready for operation again and can be switched on again.

Battery operation: The lithium-ion battery is protected against deep discharge by the "Electronic Cell Protection (ECP)" system. When the battery is discharged, the measuring instrument switches off via the protection circuit.

If the measuring instrument switches off automatically due to a discharged battery, switch off the measuring instrument using the on/off switch. Before switching the measuring instrument on again, charge the battery. Otherwise, the battery may be damaged.

Automatic leveling of the measuring instrument

The automatic leveling function compensates for unevenness within the automatic leveling range of ±4°. Leveling is complete as soon as the laser lines stop blinking.

If automatic leveling is not possible, e.g., if the base on which the measuring tool is installed deviates from the horizontal by more than 4°, the laser lines will blink.

Place the measuring tool horizontally and wait until the tool has performed automatic leveling. As soon as the measuring tool is back within the automatic leveling range of ±4°, the laser lines will light up continuously.

If the position of the measuring tool changes during operation, the tool will level itself again automatically. After significant changes in position, leveling may take place at a different height. To avoid errors in height, check the reference point after repeated leveling to see if the laser lines coincide (see "Leveling the measuring tool to a height", p. 121).

Leveling the measuring tool to a height

The measuring tool creates two laser lines that can be seen on the surface at a distance of approx. 50 cm from the measuring tool. The lines must be brought together at a reference point that can be seen on the ground. To do this, turn the two height adjustment knobs clockwise or counterclockwise until the laser lines coincide at the reference point and only one line is visible.

If the two laser lines cannot be brought together by turning the height adjustment knobs, this means that the measuring tool is significantly higher or lower than the ground surface. Set up the measuring tool at another location on the ground with less difference in height and bring the laser lines together at that point.

Starting the remote control operation (GSL 2 Set)

Protect the remote control from direct sunlight. Do not expose the remote control to extreme temperatures or temperature fluctuations. In particular, do not leave it in a car for a long time. In case of large temperature fluctuations, allow the remote control to adjust to the temperature before using it.

When inserting the battery, ensure sufficient voltage for the remote control.

The signals from the remote control must be aimed directly at the receiving lens from the front and from above. If it is not possible to aim the remote control directly at the receiving lens, the range is reduced. The working range is reduced when the signal is weak – it can be increased again by reflecting the signal (e.g., off a wall).

Switching on the measuring tool with the remote control is only possible after the measuring tool has been switched on automatically, if the switch is still in the "On" position. Switching off with the remote control is not possible.

Measurement

Manual operation (GSL 2)

Rotate the upper part of the measuring instrument to the location you need to check. After rotating the instrument, wait until the measuring instrument has finished leveling and the laser beams are no longer visible. Only then check whether the laser beams coincide.

Automatic rotation (GSL 2 Set)

Rotate the upper part of the measuring instrument using the remote control to check the area. Manual rotation is not possible.

The following rotation methods are available:

Press button 19 to start fast continuous rotation clockwise. Pressing button 19 again stops the rotation.

Press button 14 to start fast continuous rotation counterclockwise. Pressing button 14 again stops the rotation.

Press button 18 to start slow continuous rotation clockwise. Pressing button 18 again stops the rotation.

Press button 15 to start slow continuous rotation counterclockwise. Pressing button 15 again stops the rotation.

Press button 17 for one short rotation clockwise. For each subsequent rotation, press button 17 again.

Press button 16 for one short rotation counterclockwise. For each subsequent rotation, press button 16 again.

Analysis of measurement results (see figure D)

The laser beams are located on the surface at the height of the reference level (see "Aligning the measuring tool by height", p. 121):

All points where the two laser beams coincide with each other are at the same height as the reference level. If the beams run parallel to each other or intersect, this means that the height of the area differs at that location from the reference level.

Measure the difference in height of the area relative to the reference point. Check the sighting mark so that the left laser beam passes exactly along the left reference line of the sighting mark. Move the upper part of the sighting mark up or down until the notch 11 of the sighting mark rests against the reference point. The difference in millimeters in height between the reference point and the measurement point can then be read from the right laser beam on the sighting mark.

If the laser beams are at the same angle to the working surface of the earth, this indicates that the surface of the earth has a slope.

Instructions for use

Then check that the laser beams coincide across the entire width. The width of the laser beams changes depending on the distance.

Transporting the measuring instrument

For easier transport of the measuring instrument, use the handle 3. If necessary, fold the handle upward.

Working with the laser glasses (accessory)

The laser glasses filter out ambient light. Thanks to this, the red light of the laser becomes more visible to the human eye.

Do not use the laser glasses as protective glasses. The laser glasses serve for better recognition of the laser beam, but they do not protect against laser radiation. Do not use the laser glasses as sunglasses or in road traffic. The laser glasses do not provide full protection against ultraviolet radiation and impair color perception.

Instructions for optimal handling of the battery

Protect the battery from the effects of moisture

Store the battery only in the temperature range from 0°C to 50°C. For example, do not leave the battery in the car in summer.

A significant reduction in the operating time of the battery after charging indicates that the battery has exhausted its service life and must be replaced.

Observe the disposal instructions.

Maintenance and service

Safety instructions

Laser surface

Read all instructions and follow them to work with the measuring instrument safely and correctly. Never operate the measuring tool before the warning labels have been checked for legibility. Keep these instructions and pass them on together with the measuring tool when it is handed over to someone else.

Improper use or failure to follow the instructions specified in these operating instructions may lead to dangerous situations and injuries. The measuring tool is supplied with warning labels (in the illustration of the measuring tool on page 2, they are marked with number 2).

Some of the warning label text is also in the language of your country. Read it before initial operation and follow the instructions in your language.

Do not point the laser beam at people or animals, and do not look into the laser beam yourself. This measuring device creates a laser beam in class 2 according to IEC 60825-1. Looking directly into the laser beam can damage your eyes.

If laser radiation hits your eye, close your eyes and turn your head away from the beam immediately. Do not use laser viewing glasses as protective glasses. Laser viewing glasses are intended for better recognition of the laser beam, but they do not protect against laser radiation.

Do not use laser viewing glasses for protection from the sun or while driving. Laser viewing glasses do not provide full protection against UV radiation and reduce color perception. Never open the laser device. Repairs should only be carried out by qualified specialists and only with original spare parts. Only under these conditions will your measuring device remain safe. Avoid reflections of the laser beam off glossy surfaces, such as windows or mirrors. Eyes can be damaged even by a reflected laser beam. The measuring device may only be serviced by persons who are familiar with laser devices. According to EN 60825-1, in addition to all this, the laser aperture on the device and the skin must be protected, as well as the use of laser protection for safety reasons. Do not operate the measuring device in environments where there is a risk of explosion due to the presence of flammable liquids, gases, or dust. Sparks can be created in the measuring device, which may ignite dust or vapors.

The laser measuring tool is intended for measuring distances, areas, and volumes. It can be used indoors and outdoors. You can also use it to measure the height of a room. Determine the working range of the measuring tool using the corresponding tables that indicate the laser operation. This way you can avoid entering a dangerous zone for other people. Do not store the measuring tool in places accessible to other people. People who are not familiar with the measuring tool should not use it. During use of the measuring tool with a laser, be aware of possible hazards. Improper use can lead to injury. Ensure that the laser zone is clearly marked or fenced off. Laser beams in controlled zones must be marked to prevent entry by other people. Avoid misuse of the measuring tool (e.g., during installation, maintenance, or transport), and also when transporting it, remove the battery from the tool. When the device is switched on, there is a risk of injury.

Ukrainian 125

Do not expose the battery to fire. There is a risk of short circuit.

Protect the battery from high temperatures, e.g., from prolonged sunlight, fire, water, and moisture. There is a risk of explosion.

Store the battery away from metal objects such as paper clips, coins, keys, nails, screws, or other small metal objects that could cause contact bridging. Short circuiting the battery contacts can cause burns or damage. If the battery is used incorrectly, it may leak. Avoid contact with the liquid. If contact occurs, rinse the affected area with plenty of water. If liquid gets into the eyes, seek medical attention immediately. Liquid leaking from the battery can cause skin irritation or chemical burns. If the battery is damaged or used improperly, it may emit fumes. Ventilate the area and seek medical attention if you experience any discomfort. The fumes may cause respiratory irritation. Charge the battery only with the charger recommended by the manufacturer. The charger may overheat if used with batteries not intended for it. Use the battery only with the measuring tool. Under these conditions, the battery will be protected from dangerous overload. Use only original Bosch batteries with the voltage specified on the nameplate of your measuring tool. Using other batteries, e.g., imitation batteries, rechargeable batteries, or batteries from other manufacturers, poses a risk of injury and damage to property due to battery explosion.

Do not install the measuring tool and the charger near cardiac pacemakers. The magnets of the measuring tool and the charger create a field that can adversely affect the function of cardiac pacemakers.

Temporary exposure to magnetic fields can affect the operation of the device and lead to data loss or damage to magnetic media. Magnetizing the device and its components can cause irreversible data loss.

Remote control unit (GSL 2 Set)

Read all instructions carefully. Save these instructions.

Repair of the remote control unit should only be carried out by qualified personnel using original spare parts. This is also necessary to ensure the safe functioning of the remote control unit. Do not operate the remote control unit in environments where there is a risk of explosion due to the presence of flammable liquids, gases, or dust. Sparks may be generated in the remote control unit, which could ignite dust or vapors.

Remove the batteries if you will not be using the remote control unit for an extended period. During prolonged storage, the batteries may corrode and self-discharge.

Operation

Commissioning the surface laser

Protect the measuring device from moisture and direct sunlight. Do not expose the measuring device to extreme temperatures or temperature fluctuations. In particular, do not leave it in a car for extended periods. If the measuring device has been subjected to extreme temperatures, allow it to stabilize to its own temperature before switching it on. Extreme temperatures and temperature fluctuations can affect the accuracy of the measuring device. Avoid strong impacts and dropping the instrument. After strong impacts, check the accuracy of the measuring device at an authorized Bosch service center. When transporting the measuring device, switch it off. When switching off, the pendulum unit locks to prevent damage to the components from strong impacts.

Installing the measuring device

Mount the measuring instrument onto the tripod or onto a stable surface, and check it.

The accuracy of the device can be affected by ambient temperature. Especially temperature fluctuations that occur when moving from cold to warm environments can cause deviations in the laser beam. Since temperature fluctuations are greatest near the ground, the measuring instrument should be set up in the center of the area being checked.

Switching On/Off

To switch on the measuring device, slide the switch to the "On" position. Immediately after switching on, the measuring device emits laser beams from the exit openings.

Do not point the laser beam at people or animals (especially at eye level), and do not look into the laser beam yourself (even from a distance).

To switch off the measuring device, slide the switch to the "Off" position. When switching off, the pendulum unit locks.

Do not turn on the power tool or operate it using the remote control if it is switched off. The tool will automatically switch off after a certain period of inactivity to save battery power.

To switch the power tool back on, press the on/off switch again if necessary.

GSL 2 Set: The automatic switch-off function can be reactivated by pressing the on/off button on the control panel.

Do not leave the power tool switched on without supervision. After finishing work, switch off the power tool. The batteries can be discharged by prolonged inactivity.

The maximum permissible operating temperature is 50°C. If the temperature exceeds this limit, the power tool switches off automatically. After the power tool has cooled down, it is ready for use again and can be switched on.

Battery operation: The battery is protected against deep discharge by the "Electronic Cell Protection (ECP)". When the battery is discharged, the power tool switches off via the protective circuit.

If the power tool switches off automatically due to a discharged battery, switch off the power tool using the on/off switch. Charge the battery before switching the power tool on again. Otherwise, the battery may be damaged.

Automatic levelling of the power tool

Automatic levelling compensates for unevenness within the self-levelling range of ±4°. Levelling is completed as soon as the laser lines stop moving.

If automatic levelling is not possible, e.g., because the surface on which the power tool is placed deviates from the horizontal by more than 4°, the laser lines flash.

In such a case, place the power tool in a horizontal position and wait until automatic levelling has been carried out. As soon as the power tool is within the self-levelling range of ±4°, the laser lines light up continuously.

If the position of the power tool changes during operation, it levels itself again automatically. In the event of significant changes in position, levelling is carried out at a different height. To avoid this height difference, check the laser lines again after levelling and adjust them if necessary (see "Levelling the power tool by height", page 129).

Ukrainian 129

Levelling the power tool by height

The power tool projects laser lines onto a surface at a distance of approx. 50 cm from the power tool. The lines must be aligned with a reference point that is marked on the surface. Then turn the knob for height adjustment in the direction of the arrow until the laser lines coincide with the reference point and are at the same height.

The laser beam must not be directed at one point when rotating the knob to adjust the height. This means that the adjusted instrument should be positioned higher or lower relative to the ground surface. Install the adjusted instrument at the desired height above the ground surface, then rotate the knob to adjust the height until the laser beams are directed at one point.

Starting the remote control unit (GSL 2 Set)

Protect the remote control from direct sunlight and extreme temperatures or temperature fluctuations. In particular, do not leave it in a car for a long time. If the remote control is exposed to temperature fluctuations, when turning it on, it may take some time to stabilize its temperature.

The remote control is supplied with sufficient battery power for operation.

The signal from the remote control must be directed at the receiver from a distance of 4 m from the front and from above diagonally. For the remote control, the signal cannot be directed at the receiver from a distance, the distance to the receiver changes. Thanks to the signal delay (e.g., on walls), the radius of action can be increased by reflecting the signal.

Turning on the remote control is only possible after the measuring tool has been turned on. The remote control cannot be turned on if the measuring tool is in the "On" position. Turning on the remote control is not possible.

Alignment procedure

Manual rotation (GSL 2)

Turn the upper part of the alignment tool to the left until it stops. The rotation stops when the alignment tool is no longer moving the laser beams. After that, check whether the laser beams coincide.

Automatic rotation (GSL 2 Set)

Turn the upper part of the alignment tool using the remote control to check the surface. Manual rotation is not possible.

Select the rotation mode:

Press button 19 to start continuous rotation with the line laser. Pressing button 19 again stops the rotation.

Press button 14 to start continuous rotation with the point laser. Pressing button 14 again stops the rotation.

Press button 18 to start continuous rotation with the line laser. Pressing button 18 again stops the rotation.

Press button 15 briefly to turn on the laser pointer. Pressing button 15 again turns it off.

Press button 17 once briefly to turn on the laser pointer. To turn it off again, press button 17.

Press button 16 briefly to turn on the laser pointer. To turn it off again, press button 16.

Analysis of measurement results (see Fig. D-G)

According to the measurement, the laser beam is at the same height as the reference point (see "Adjusting the measuring tool by height, page 129"):

All points where the laser beams intersect each other are at the same height as the reference point. The laser beams run parallel to each other, so the height of the tool's surface is determined by the reference point.

To adjust the height difference between the tool surface and the reference point, set the adjustment mark 10 at the check point. Turn the adjustment mark so that the laser beam passes exactly through the reference point or the adjustment mark. Press the upper part of the adjustment mark up or down until the tip 11 of the adjustment mark touches the surface to be measured. The difference between the reference point and the measuring point is then shown on the adjustment mark in millimeters.

If the laser beams diverge from the tool surface at different angles, this indicates that the tool surface is tilted.

Working instructions

Make sure that the laser beams are aligned across the entire width. The width of the laser beams changes depending on the distance.

Transporting the measuring tool

For safe transport of the measuring tool, use the handle. If necessary, fold the handle up.

To open the battery compartment cover, press the button 20 and pull out the cover. Insert the batteries. Pay attention to the correct polarity, shown on the diagram on the inside of the battery compartment cover.

Always replace all batteries at the same time. Use only batteries from the same manufacturer and of the same type.

When the stationary control is not used for a long time, remove the batteries from it. If the batteries are left for a long time, they may leak and cause damage.

Working with the device

Switching on the laser level for flatness measurement

First, place the measuring device on a horizontal surface or fix it on a tripod. Do not expose the measuring device to extreme temperatures or temperature fluctuations. For example, do not leave it in a car for a long time. At high temperatures, place the measuring device

at a suitable temperature. Extreme temperatures or temperature fluctuations may affect the accuracy of the measuring device.

Avoid strong impacts or drops of the measuring device. After strong mechanical impact, check the accuracy of the measuring device at a qualified service center for electronic instruments. When you finish working, switch it off. When the device is switched off, the pendulum unit is locked automatically; otherwise, it may be damaged during transport.

Place the measuring device in working position

Place the measuring device on a solid base on the surface to be checked.

The accuracy of the leveling may be affected by the ambient temperature. Large temperature differences from the floor upwards may cause deflection of the laser beam. Since the temperature gradient is greatest near the floor, place the measuring device on a stable surface in the middle of the area to be checked.

Switching on and off

To switch on the measuring device, press the on/off switch 8 to the "On" position. After switching on, the measuring device emits a laser beam through the opening 1.

Do not point the laser beam at people or animals (especially not at eye level); do not look into the laser beam yourself (from the front or from a close distance).

The measuring tool switches off automatically if the measuring tool is not used for a while. The laser lines blink before the measuring tool switches off.

If the measuring tool is not used, the laser lines blink before the measuring tool switches off automatically after approx. 30 min. To switch on the measuring tool again, press the On/Off button.

After the automatic switch-off of the measuring tool, press the On/Off button to switch it on again. If necessary, switch it on again.

GSL 2 Set: After the automatic switch-off of the measuring tool, you can switch it on again by pressing the On/Off button.

Do not leave the tool switched on unattended; switch it off after use. The laser beam may be dangerous to the eyes.

When the maximum permissible temperature of 50 °C is exceeded, the tool switches off to protect the laser diode. After cooling down, the measuring tool can be switched on again.

Battery operation: The battery is protected against deep discharge by the "Electronic Cell Protection (ECP)" system. When the battery is discharged, the measuring tool switches off automatically.

150|Bulgarian

If the measuring tool switches off automatically due to low battery, switch it off and on again with the On/Off button. Before switching on the measuring tool again, charge the battery. Otherwise the battery may be damaged.

Levelling of the measuring tool

The automatic levelling system compensates for deviations within the self-levelling range of ±4°. The levelling process is complete when the laser lines stop moving.

If automatic levelling is not possible, e.g. because the surface on which the tool is placed deviates from the horizontal by more than 4°, the laser lines flash.

Place the measuring tool horizontally and switch on the automatic levelling. When the measuring tool is within the self-levelling range of ±4°, the laser lines light up continuously.

The laser lines are levelled automatically during operation. If the position of the tool changes significantly, the lines are levelled again. After repeated levelling, check the height of the laser lines on the reference surface [see "Setting the measuring tool height", page 150] to avoid errors in height measurement.

Setting the measuring tool height

The measuring tool has two laser lines, which are switched on and project onto the floor at a distance of approx. 50 cm from the tool. In the reference position, in which the lines are closest to the measuring tool, they must be covered. By turning the height adjustment knob counterclockwise, until the two laser lines are covered in the reference position, only one line should be visible.

If the two laser lines cannot be covered by turning the height adjustment knob, the measuring tool must be set to a larger distance on the floor plane. Place the measuring tool at another point, at a smaller distance from the floor, and then cover the two laser lines by adjusting.

Switching on the remote control (GSL 2 Set)

Before using the remote control, read the safety instructions. Do not expose the remote control to extreme temperatures or temperature fluctuations. E.g., do not leave it in the car for a long time. In case of large temperature differences, allow the remote control to acclimate before switching it on.

When the battery is inserted in the remote control and the voltage is sufficiently high, it is ready for operation.

The signals of the remote control must reach the receiver of the measuring tool directly and must not be obstructed. If the remote control cannot be aimed directly at the receiver, its range is reduced. Due to reflection of the beams (e.g., on walls), the operating range can also be increased.

Switching on the measuring tool with the remote control is possible. After automatic switch-off of the measuring tool, if the start button is pressed, it can be switched on again. Switching off with the remote control is possible.

Evaluation of the test results (see Figures D-G)

Through the two laser lines, if the surface is at the same height as the reference point (see "Setting the measuring tool by height", page 150):

All points where the laser lines intersect are at the same height as the reference point. If the laser lines are interrupted, the height of the measured surface differs from the reference point.

To measure the deviation of the surface, place the laser receiver 10 on the test point. Rotate the laser receiver so that the upper laser line coincides with the upper reference line on the receiver. Move the upper part of the laser receiver up or down until the top of the laser receiver reaches the measuring point. The position of the upper laser line on the laser receiver indicates the difference in height between the reference point and the point being measured.

If the laser lines on the measured surface are inclined at a constant angle, the surface is inclined.

Working instructions

Note: The laser lines may be offset from each other in width. The width of the laser lines changes with distance.

Pay attention to the polarity according to the figure on the inner side of the lid of the battery compartment. Always replace all batteries at once. Use only batteries from one manufacturer with the same capacity. If you do not use the measuring instrument for a longer period, remove the batteries. If they are

stored for a longer period, the batteries may corrode and discharge themselves.

Working with the battery (see figure C)

Use only original Bosch lithium-ion batteries with the voltage indicated on the

specification plate of your measuring instrument.

Using other batteries can lead to injuries and fire hazards.

Note: Using batteries not suitable for your measuring instrument can lead to malfunction or damage to the measuring instrument.

Note: The battery is delivered partially charged. To ensure full battery capacity, charge the battery completely before first use.

Use only chargers listed on the page with the accessories. Only these chargers are suitable for the lithium-ion battery used in your measuring instrument.

Lithium-ion batteries can be charged at any time without reducing their service life. Interrupting the charging process does not damage the battery.

The charging process does not damage the battery.

The battery is equipped with temperature control, which allows charging only at temperatures between 0°C and 45°C. This achieves a long service life of the battery.

To insert or replace the batteries, the positioning according to the figure must be carried out in the highest position. Turn the locking knob 9 of the positioning according to the figure to the end in the right direction against the glass of the watch.

To insert the batteries, press on the locking block 6 and open the lid of the battery compartment. Press the battery into the compartment to the end and close the lid.

LED capacity

Continuous light 3 x green ≥ 2/3

Continuous light 2 x green ≥ 1/3

Continuous light 1 x green < 1/3

Flashing light 1 x green Reserve

Working with the remote control (GSL 2 Set)

For working with the remote control, the use of alkaline-manganese batteries is recommended.

To open the battery pack cover 20, press the locking mechanism 21 and remove the cover from the battery pack. Insert the batteries. Pay attention to the polarity in accordance with the indicator on the inside of the battery pack cover.

Always replace all batteries at the same time. Use only batteries of the same type and with the same capacity.

If you do not use the remote control for a longer period, remove the batteries. If they are stored for a longer period, the batteries may corrode and discharge.

Putting the device into use

The device is intended for measuring non-contact surface temperature. Do not expose the device to direct sunlight. Do not expose the device to extreme temperatures or temperature fluctuations. For example, do not leave it in the car for a long time. When exposed to temperature fluctuations, leave the device to acclimatize before putting it into use. In extreme temperatures or temperature fluctuations, the accuracy of the device may be affected. Avoid strong impacts on the device. After strong impacts, the calibration of the device should be checked at an authorized service center. Remove the device during transport. When removed, the laser unit is blocked, which would be activated during intense movement.

Positioning the device

Place the device on a flat surface of the object to be checked.

The accuracy of the measurement can be affected by the ambient temperature. Especially temperature differences

that occur from the floor upwards can distort the laser beam. The largest temperature differences are near the floor, so the device should always be positioned in the middle of the flat surface of the object to be checked.

Switching on/off

To switch on the device, press and hold the switch for on/off in the "On" position. When switched on, the device emits a laser beam from the opening 1.

Do not point the laser beam at people or animals (especially not at eye level), and do not look directly into it (even from a distance).

To switch off the device, press and hold the switch for on/off in the "Off" position. When switched off, the laser unit is blocked.

If the device is not used for about 30 minutes, it is not controlled via remote control, then it automatically switches off to save the batteries.

After automatic switch-off, switch off the device with the switch for on/off and, if necessary, switch it on again.

GSL 2 Set: After automatic switch-off, you can switch the device on again by pressing any key on the remote control.

Do not leave the device switched on when not in use; switch it off after use. The batteries can be drained by the laser beam.

Before use, the device must be allowed to reach operating temperature. At 50 °C, the laser diode is excluded. If it is turned on, the device may be turned on again after a repeated warm-up.

Battery operation: The lithium-ion battery is protected by "Electronic Cell Protection (ECP)" against deep discharge. If the battery is discharged, the device switches off with a protective circuit. If the device switches off automatically despite a charged battery, switch it off and on again using the switch. Charge the battery before switching the device on again. If the battery still does not work, it may be defective.

Levelling the measuring tool

The levelling automation automatically levels the laser lines within the self-levelling range of ±4°. Levelling is complete when the laser lines no longer move.

If automatic levelling is not possible, e.g. because the surface on which the measuring tool is standing deviates by more than 4° from the horizontal, the laser lines flash.

Place the measuring tool horizontally and wait for self-levelling. Once the measuring tool is within the self-levelling range of ±4°, the laser lines light up continuously.

Macedonian | 157

When changing the position during operation, the measuring tool levels itself automatically. When changing the position, a different height may be possible. After repeated levelling, check the coverage of the laser lines on the reference point (see "Measuring the measuring tool height", page 157) to avoid errors in height.

Measuring the measuring tool height

The measuring tool emits two laser lines at a distance of approx. 50 cm in front of the measuring tool on the floor surface. The lines must be aligned on the reference point, which was previously marked on the floor surface. Then turn the tool to the end of the 9 on the dial for height adjustment. In the direction opposite to the clock hands, until the laser lines are aligned on the reference point and only one laser line is visible.

If the two laser lines cannot be aligned by turning the height adjustment, this means that the measuring tool is significantly out of level or is tilted from the floor surface. Place the measuring tool on another point on the floor surface with a smaller height difference and align the two laser lines there.

Operation with the remote control (GSL 2 Set)

Protect the remote control from moisture and direct sunlight. Do not expose the remote control to extreme temperatures or temperature fluctuations. For example, do not leave it in the car for a long time. In case of large temperature fluctuations, let the remote control acclimatize before using it.

If the battery is low, the remote control will soon need to be replaced.

The remote control must be held until the receiver is switched on and the direction of rotation is correct. If the remote control cannot be paired with the receiver, the fault is indicated. By reflecting the signal (e.g., on walls), the signal can be absorbed and attenuated.

Switching off the measuring device via remote control is possible only if the automatic switching off of the measuring device is activated, provided the switch for switching on/off is still in the "on" position. Switching off via remote control is not possible.

Manual measurement

Distance measurement (GSL 2)

Turn the upper part of the measuring device to the position you want to check. Wait until the measuring device has leveled itself, then the laser lines are displayed. Then check the laser lines again.

Automatic turning (GSL 2 Set)

Turn the upper part of the measuring device with the help of the remote control to check the surface. Manual turning is not possible.

You can select the following rotation speeds:

Press button 19 to start fast, continuous rotation in the direction of the clock hands. With one more press of button 19, the rotation stops.

Press button 14 to start fast, continuous rotation in the direction opposite to the clock hands. With one more press of button 14, the rotation stops.

Press button 18 to start slow, continuous rotation in the direction of the clock hands. With one more press of button 18, the rotation stops.

Press button 15 to start slow, continuous rotation in the direction opposite to the clock hands. With one more press of button 15, the rotation stops.

Press button 17 for a single, short rotation in the direction of the clock hands. For continuous movement, press button 17 again.

Press button 16 for a single, short rotation in the direction opposite to the clock hands. For continuous movement, press button 16 again.

Checking the measurement results (GSL 2 D-G)

The laser level is a reference point (for verification of the measuring tool's accuracy, page 157):

The two laser lines must not lie one above the other, but must be at the same height as the reference point. If the two laser lines are at different heights or are interrupted, then the height of the surface at that point deviates from the reference point.

To measure the deviation of the surface, place the measuring tape at the point to be checked. Align the measuring tape so that the left laser line is at the zero mark of the left reference line on the measuring tape. Place the upper edge of the measuring tape on the floor. Then, read the value at the point to be measured. At the position of the right laser line on the measuring tape, you can read the height difference between the reference point and the measured point in millimeters.

If the laser lines deviate from each other at a constant angle, this means that the surface is not flat.

Working advice

Always ensure that the laser lines are aligned one above the other. The position of the laser lines changes with the deviation.

Transport leveling

The bracket helps with easy transport of the measuring tool. If necessary, fold the bracket upward.

Laser goggles (accessory)

The laser goggles filter out ambient light. This makes the red laser light of the laser appear brighter to the eye.

Do not use the laser goggles as safety goggles. The laser goggles are used for better recognition of the laser beam, but they do not protect against laser radiation. Do not use the laser goggles as sunglasses or in traffic. The laser goggles do not provide full UV protection and reduce color recognition.

Battery advice

Keep the battery away from moisture and water.

Store the battery within the temperature range of 0° C to 50° C. Do not leave the battery in the car for a long time.

The time for operation until the battery is completely discharged must be checked.

Pay attention to the maintenance instructions.

Maintenance and service

Maintenance and cleaning

The measuring device must be regularly inspected and maintained (e.g., lubrication, maintenance, etc.) as well as during its transport and maintenance. The batteries must be removed from the measuring device. In case of careless handling, there is a risk of injury when inserting/removing the battery.

Safety instructions

Surface laser

You must read and pay attention to all instructions in order to work with the tool without danger and safely. Do not allow warning plates to become illegible. KEEP THIS INSTRUCTION MANUAL IN A SAFE PLACE AND HAND IT OVER TOGETHER WITH THE TOOL IF YOU PASS IT ON.

• Caution - if other equipment for work or adjustment than those specified here is used, or other procedures are performed, this may lead to radiation explosions. The measuring tool is supplied with two warning plates (marked with number 2 in the graphic page of the measuring tool).

If the text on the warning plates is not in your language, stick the supplied labels in your language over them before first use.

Do not direct the laser beam at people or animals, and do not look into the laser beam yourself. This measuring tool produces laser radiation of laser class 3R according to IEC 60825-1. Direct eye exposure to the laser beam—even from a greater distance—can damage the eye. If laser radiation enters the eye, you must consciously close your eye and immediately turn your head away from the beam. Do not use laser viewing glasses as protective goggles. Laser viewing glasses are used to better recognize the laser beam; they do not protect against laser radiation. Do not use laser viewing glasses as sunglasses or while driving. Laser viewing glasses do not provide full UV protection and reduce color perception. Do not make any modifications to the laser equipment. Have your measuring tool repaired by qualified personnel using only original spare parts. This ensures that the safety of the measuring tool is maintained. Avoid reflections of the laser beam on flat surfaces such as windows and mirrors. Even a reflected laser beam can cause eye damage. Only persons who are familiar with the operation of laser devices should work with the measuring tool. According to EN 60825-1, this includes, among other things, knowledge of the biological effects of lasers on the eyes and skin, as well as the correct use of laser protection and the elimination of hazards. Do not work with the measuring tool in environments where there is a risk of explosion, where flammable liquids, gases, or dust are present. Sparks can be generated in the measuring tool, which could ignite dust or vapors. Always position the measuring tool so that the laser beams extend well above or below eye level. This ensures that eye damage is avoided. Mark the area where the measuring tool is used with a suitable laser warning sign. This prevents unauthorized persons from entering the danger zone. Do not store the measuring tool in places where unauthorized persons have access. Persons who are not familiar with the operation of the measuring tool can injure themselves and others. ▸ Pay attention to possible national regulations when using a measuring tool with laser class 3R. Failure to comply with these regulations can result in injury. Ensure that the laser radiation area is supervised and protected. Limiting laser radiation to a controlled area prevents eye damage to third parties. Remove the battery or rechargeable battery before all work on the measuring tool (e.g., assembly, maintenance, etc.) as well as during transport and storage. There is a risk of fire if the on/off switch is accidentally activated. Do not open the battery. There is a risk of short circuit.

Protect the battery from heat, for example from direct sunlight, fire, water, and moisture. There is a risk of explosion.

Keep unused battery away from paper clips, coins, keys, nails, screws, or other small metal objects that could cause bridging of contacts. Short-circuiting between battery contacts can result in burns or fire. If the battery is misused, liquid may leak from it. Avoid contact with it. In case of accidental contact, rinse with water. If liquid gets into eyes, seek additional medical help. Battery liquid that leaks out can cause skin irritation or burns. If the battery is damaged or improperly used, vapors may be emitted. Provide fresh air and seek medical help if you experience discomfort. Vapors can irritate the respiratory tract. Charge batteries only in chargers recommended by the manufacturer. For a charger that is suitable for a specific type of battery, there is a risk of fire when used with other batteries. Use the battery only in conjunction with your Bosch measuring tool. Only this battery can protect against dangerous overload. Use only original Bosch batteries with the voltage specified on the rating plate of your measuring tool. When using other batteries, such as imitations, reconditioned batteries, or foreign brands, there is a risk of injury as well as damage to objects from a battery that may explode.

Do not bring the measuring tool and the laser target plate 10 near pacemakers. The magnets of the measuring tool and the laser target plate produce a field that can impair the function of pacemakers.

Keep the measuring tool and the laser target plate 10 away from magnetic data carriers and devices sensitive to magnetism. The effect of the magnets of the measuring tool and the laser target plate can lead to irreversible data loss.
