Assembly

Inserting/changing the batteries

It is recommended that you use alkaline manganese batteries to operate the measuring tool.

If required, turn the magnetic rotating mount (3) to the side so that the battery compartment cover (6) is not obstructed.

Press the locking mechanism (5) upwards to open the battery compartment cover (6) and remove the battery compartment cover. Insert the batteries.

When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.

Reattach the battery compartment cover (6) and press it firmly into place at the marked point above the locking mechanism (5).

If the batteries are running low, the laser points will gradually become dimmer.

If the batteries are almost empty, the laser points will flash 5 times every minute.

If the batteries are empty, the laser points will flash once before the measuring tool switches off.

Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity.

Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage in the measuring tool.

Operation

Starting Operation

Protect the measuring tool from moisture and direct sunlight. Do not expose the measuring tool to any extreme temperatures or fluctuations in temperature. For example, do not leave it in a car for extended periods of time. If it has been subjected to significant fluctuations in temperature, first allow the measuring tool to adjust to the ambient temperature and then always carry out an accuracy check before continuing work (see "Accuracy Check of the Measuring Tool", page 25). The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature. Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences (see "Accuracy Check of the Measuring Tool", page 25). Switch the measuring tool off when transporting it. The pendulum unit is locked when the tool is switched off, as it can otherwise be damaged by big movements.

Switching On/Off

To switch on the measuring tool, slide the on/off switch (2) to the ON position. As soon as it is switched on, the measuring tool emits laser beams from the outlet apertures (1).

• Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance). To switch off the measuring tool, slide the on/off switch (2) to the OFF position. The pendulum unit is locked when the tool is switched off.
• Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.

If the maximum permitted operating temperature of 45°C is exceeded, the tool shuts down to protect the laser diode. Once it has cooled down, the measuring tool is operational again and can be switched back on.

Automatic shut-off

The measuring tool automatically switches itself off after 60 minutes of operation.

If the switched-on measuring tool is not within the self-levelling range (the laser points flash continuously), the automatic shut-off is reset to 60 minutes.

Automatic Levelling

Position the measuring tool on a level, firm support or attach it to a tripod (11).

To use the bottom laser point, rotate the measuring tool on the magnetic rotating mount (3) in such a manner that the laser point can be seen on the floor.

After switching on, the automatic levelling function automatically compensates irregularities within the self-levelling range of ±4°. The levelling is finished as soon as the laser points light up continuously (i.e. no longer flashing) and do not move any more.

If automatic levelling 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 points will flash continuously and quickly.

If this is the case, set up the measuring tool in a 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 points will light up continuously.

In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again. After each levelling process, check the position of the horizontal and/or vertical laser points in relation to the reference points to avoid errors arising from a change in the measuring tool's position.

Accuracy Check of the Measuring Tool

Influences on Accuracy

The largest influence is exerted by the ambient temperature. In particular, temperature differences that occur from the ground upwards can refract the laser beam.

Since the temperature stratification is greatest at ground level, you should always mount the measuring tool on a tripod for measuring distances of 20 m or more. In addition, position the measuring tool in the centre of the work surface, wherever this is possible.

In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the levelling accuracy each time before beginning work.

Should the measuring tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch after-sales service.

Checking the horizontal levelling accuracy

For this check, you will need a free measuring distance of 5 m on firm ground between two walls (designated A and B).

• Mount the measuring tool close to wall A on a tripod, or place it on a firm, flat surface. Switch on the measuring tool.

• Aim the horizontal laser beam that runs parallel to the longitudinal axis of the measuring tool at the closer wall A and allow the measuring tool to level in. Mark the centre of the laser point on the wall (point I).

• Turn the measuring tool 180°, allow it to level in and mark the centre point of the laser beam on the opposite wall B (point II).
• Position the measuring tool - without rotating it - close to wall B, switch it on and allow it to level in.

• Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the centre point of the laser beam exactly hits the previously marked point II on wall B.

• Turn the measuring tool 180° without adjusting the height. Allow it to level in, then mark the centre point of the laser beam on wall A (point III). Ensure that point III is as vertical as possible above or below point I.
• The discrepancy d between the two marked points I and III on wall A reveals the actual height deviation of the measuring tool along the longitudinal axis.

The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as follows:

10 m × ±0.35 mm/m = ±3.5 mm. The discrepancy d between points I and III must therefore amount to no more than 3.5 mm.

GPL 5 G: Repeat the measuring process for the two side laser beams that run along the transverse axis of the measuring tool. To do this, turn the measuring tool 90° clockwise or anticlockwise before beginning the measuring process.

Checking Plumb Accuracy

For this check, you will need a clear measuring space on firm ground with a distance of approx. 2.5 m between the floor and the ceiling.

• Place the measuring tool on the floor. Switch the measuring tool on and rotate it on the magnetic rotating mount (3) in such a manner that the bottom laser point can be seen on the floor. Allow the measuring tool to level in.

• Mark the centre of the top laser point on the ceiling (point I). Also mark the centre of the bottom laser point on the floor (point II).

• Turn the measuring tool by 180°. Position it so that the centre of the bottom laser point falls onto the marked point II. Allow the measuring tool to level in. Mark the centre of the top laser point (point III).
• The discrepancy d between the two marked points I and III on the ceiling reveals the actual deviation of the measuring tool from the vertical plane.

You can calculate the maximum permitted deviation as follows:

Doubled distance between floor and ceiling × 0.35 mm/m

Example: At a floor-to-ceiling distance of 2.5 m, the maximum deviation amounts to

2 × 2.5 m × ±0.35 mm/m = ±1.75 mm. The points I and III must therefore be no further

than 1.75 mm from each other.

Working Advice

Always use the centre of the laser point for marking. The size of the laser point changes with the distance.

Working with the Tripod (Accessory)

A tripod offers a stable, height-adjustable support surface for measuring. Place the measuring tool with the 1/4" tripod mount (4) on the thread of the tripod (11) or a conventional camera tripod. Tighten the measuring tool using the locking screw of the tripod.

Roughly align the tripod before switching on the measuring tool.

Attaching using the magnetic rotating mount (see figures A-B)

You can secure the measuring tool to magnetisable materials using the integrated magnetic rotating mount (3).

• Keep your fingers away from the rear side of the magnetic rotating mount while attaching the rotating mount to surfaces. The strong pulling force of the magnets (7) may jam your fingers.

Roughly align the magnetic rotating mount (3) before switching on the measuring tool. Rotate the measuring tool on the magnetic rotating mount (3) to make the bottom laser point visible or to project heights with the horizontal laser point. If you switch off and transport the measuring tool, click it back into place on the rotating mount (see figure B).

Laser Goggles (Accessory)

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

• Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
• Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.

Example applications (see figures C-E)

Examples of possible applications for the measuring tool can be found on the graphics pages.

Technical data

AUTOMATIC LEVELING

Place the measuring tool on a firm horizontal base or secure it on the tripod (11).

To use the lower laser point, turn the measuring tool on the rotating mount (3) so that the laser point is visible on the floor.

After switching on the automatic leveling function, unevenness within the self-leveling range of ±4° is compensated. Leveling is complete as soon as the laser points remain stationary and no longer move.

If automatic leveling is not possible, e.g., because the surface on which the measuring tool is placed deviates from the horizontal by more than 4°, the laser points will continue to flash quickly.

In such a case, place the measuring tool horizontally and wait for self-leveling. After the measuring tool is within the automatic leveling range of ±4°, the laser points begin to shine continuously.

During changes in position or movement during work, the measuring tool levels itself automatically. After repeated leveling, check the position of the horizontal or vertical laser point relative to the reference points to prevent errors due to displacement of the measuring tool.

Checking the accuracy of the measuring tool

Factors affecting accuracy

The greatest influence on accuracy is exerted by the ambient temperature. In particular, temperature differences that occur with increasing distance from the ground can cause deflection of the laser beam.

Since temperature differences are most noticeable near the ground, on sections longer than 20 m the measuring tool should be set up on a tripod.

In addition, place the measuring tool, if possible, in the middle of the work area.

External influences, specific to the tool (e.g., falls or heavy impacts) can also cause deviations. Therefore, always check the leveling accuracy before starting work.

216|Russian

If the measuring tool exceeds the maximum permissible deviation during the checks, send it to the Bosch service workshop for repair.

Checking the accuracy of the horizontal leveling

For the check, you need a free section of 5 m on a firm surface between two walls A and B.

- Mount the measuring tool near wall A on a tripod or place it on a firm, level surface. Switch on the measuring tool.

• Direct the horizontal laser beam, which runs parallel to the longitudinal axis of the measuring tool, at wall A. Allow the measuring tool to level itself. Mark the center of the laser point on the ceiling (point I).

-Rotate the measuring tool 180°, wait for it to level itself, and mark the center of the laser beam on the opposite wall B (point II). - Set up the measuring tool - without turning it - near wall B, switch it on, and allow it to level itself.

• Adjust the measuring tool in height (using the tripod or by placing shims underneath) so that the center of the laser beam exactly coincides with the previously marked point II on wall B.

-Rotate the measuring tool 180° without changing the height. Allow it to level itself and mark the center of the laser beam on wall A (point III). Make sure that point III is as vertically above or below point I as possible. The distance d between the two marked points I and III on wall A reflects the actual deviation of the measuring tool in height along the longitudinal axis.

On the measuring section of 2 × 5 m = 10 m, the maximum permissible deviation is:

10 m × ±0.35 mm/m = ±3.5 mm. Thus, the distance d between points I and III must not exceed max. 3.5 mm.

GPL 5 G: Repeat the measurement for the two side laser beams, which run along the transverse axis of the measuring tool. To do this, rotate the measuring tool before starting the measurement by 90° clockwise or counterclockwise.

Checking the accuracy of the plumb line

For the check, you need a free measuring section on a firm base with a distance of approx. 2.5 m between floor and ceiling.

-Place the measuring tool on the floor. Switch on the measuring tool and turn it on the magnetic rotating mount (3) so that the laser point is visible on the floor. Allow the measuring tool to level itself.

Mark the center of the upper laser point on the ceiling (point I). Also mark the center of the lower laser point on the floor (point II).

Before switching on the measuring tool, level it roughly using the leveling base.

Fastening with the magnetic swivel mount (see figures A-B)

With the integrated magnetic swivel mount (3), you can attach the measuring tool to magnetic materials.

When fastening the swivel mount to a surface, keep your fingers away from the back of the magnetic swivel mount. Due to the strong magnetic attraction (7), your fingers could get pinched.

Before switching on the measuring tool, align the magnetic swivel mount by eye (3).

Turn the measuring tool on the magnetic swivel mount (3) to make the lower laser point visible or to transfer heights using the horizontal laser line. When switching off and transporting the measuring tool, allow the measuring tool to snap back into place on the swivel mount (see figure B).

Laser viewing glasses (accessory)

Laser viewing glasses filter out ambient light. This makes the laser light appear brighter to the human eye.

Do not use the laser viewing glasses (accessory) as protective goggles. Laser viewing glasses

220|Russian

provide better recognition of the laser beam, but do not protect against laser radiation.

Do not use the laser viewing glasses (accessory) as sunglasses or while driving. Laser viewing glasses do not provide protection against UV radiation and impair color perception.

Examples of possible work applications (see figures C-E)

Examples of possible applications of the measuring tool are shown on the pages with figures.

Installation

Safety Instructions

Read all safety instructions before using the measuring tool to work safely and correctly. Using the measuring tool without following these instructions may lead to damage to the integrated safety mechanisms. Never disregard the preliminary

tables on the measuring tool due to unfamiliarity. Keep these instructions and pass them on together with the measuring tool when handing it over.

Improper use or use of the tool for purposes other than those specified in these instructions, or use of unauthorized accessories, may lead to unsafe laser operation. The measuring tool is supplied with a preliminary laser warning table (it is shown in the illustration of the measuring tool on page with the label). If the text of the preliminary laser warning table is not in your language, before first use, stick the label in your language that is included in the delivery.

Do not direct the laser beam at people or animals, and do not look into the laser beam yourself. It can damage their eyes, cause accidents, or injure the eyes.

If laser radiation enters the eye, close your eyes and immediately turn away from the beam. Do not look into the laser device. Do not use laser goggles for working with the laser (device). Laser goggles improve the recognition of the laser beam, but they do not protect against laser radiation. Do not use laser goggles for working with the laser (device) as safety goggles and do not wear them when you are behind the wheel.

Laser goggles for working with the laser do not provide complete protection against the beams and impair the recognition of colors.

Have the measuring tool repaired only by qualified specialists and only with original spare parts. Only under these conditions will your measuring tool remain safe. Do not allow children to use the laser measuring tool without supervision. Children can unintentionally injure themselves or others.

Checking the accuracy of horizontal leveling

For the check, you need a free measuring distance of 5 m on a solid surface between two walls A and B.

• Set up the measuring tool on a level surface or mount it on a tripod. Switch on the measuring tool.

• Aim the horizontal laser line, which runs parallel to the longitudinal axis of the measuring tool, at the nearby wall A. Allow the measuring tool to level in. Mark the center of the laser line on the wall (point I).

Ukrainian|229

- Turn the measuring tool by 180°, allow it to level in, and mark the center of the laser line on the opposite wall B (point II). - Position the measuring tool without turning it, near wall B, switch it on and allow it to level in.

- Adjust the height of the measuring tool (using the tripod or by placing shims underneath it) so that the center of the laser line exactly hits point II previously marked on wall B.

Storage of the measuring instrument is recommended using the alkaline-manganese battery.

When replacing the battery, press the latch (3) inward so that the battery compartment cover (6) is released.

To open the battery compartment cover (6), press the catch (5) upward and then open the cover. Insert the batteries.

Observe the correct polarity, shown in the figure on the inside of the battery compartment.

Replace the cover of the battery compartment (6) and press it until it clicks into place at the marked point on the catch (5).

With weak batteries, the quality of the laser points decreases gradually.

If the batteries are low, the laser points flash every 5 minutes.

If the batteries are exhausted, the laser points flash every 5 seconds. The measuring instrument switches off automatically.

Replace all batteries at the same time. Use only batteries from the same manufacturer and with the same capacity.

If you do not use the instrument for a long time, remove the batteries from it. During prolonged storage, batteries in the measuring instrument can corrode and discharge themselves.

Operation

Starting operation

Protect the measuring instrument from moisture and direct sunlight. Do not expose the measuring instrument to extreme temperatures or sudden temperature changes. For example, do not leave it in a car for a long time. In case of large temperature fluctuations, allow the measuring instrument to acclimate before continuing work. Then perform a check of the accuracy (see "Checking the accuracy of the measuring instrument", page 265).

In case of extreme temperatures or large temperature differences, the accuracy of the measuring instrument may be impaired.

264 | Bulgarian

After removing the batteries, the device must be checked for accuracy before it is used again (see "Checking the Accuracy of the Level", page 265). When the level is not in use, remove the batteries beforehand. When removing the batteries, the pendulum locking mechanism may be released, which could damage the device if it vibrates.

Switching On/Off

To switch on the level, press the On/Off button (2) to the "ON" position. After switching on, the level emits a laser beam through the outlet (1). Do not point the laser beam at people or animals; do not stare into the laser beam, even from a distance.

To switch off the level, press the On/Off button (2) to the "OFF" position. When switching off, the pendulum locking mechanism may be released.

Do not leave the level switched on without supervision; after finishing work, switch it off. The device may be damaged by the laser beam.

If the maximum permissible temperature of 45 °C is exceeded, the level switches off to protect the laser diode. After cooling down, the level is ready for operation again and can be switched on.

Automatic Shut-off

After 60 minutes of operation, the level switches off automatically.

The automatic shut-off is activated after 60 minutes if the switched-on level is outside the self-leveling range (the laser points flash constantly).

Automatic Self-leveling

Place the level on a horizontal, even surface or mount it on a tripod (11).

To use the full laser point, place the level on the horizontal surface so that the laser point is visible on the floor.

Before switching on, the automatic self-leveling compensates for unevenness in the self-leveling range of ±4° automatically. The leveling indicator is active when the laser points flash slowly and then stop moving.

If automatic self-leveling is not possible, e.g., when the surface on which the level is placed deviates from the horizontal by more than 4°, the laser points flash quickly.

In such a case, place the level horizontally and wait for its automatic self-leveling. When the level is placed within the limits of the self-leveling range of ±4°, the laser points start to flash continuously.

During operation, the measuring tool is leveled automatically. After repeated leveling, check the horizontal, resp. vertical laser points against the reference points to avoid errors due to displacement of the measuring tool.

Checking the accuracy of the measuring tool

Factors affecting accuracy

The greatest influence is exerted by the ambient temperature. The temperature difference from the floor upwards can cause deviations of the laser beam.

Since temperature differences are strongest near the floor, at distances of 20 m or more, it is recommended to mount the measuring tool on a tripod. If possible, place the measuring tool in the working environment.

In addition to these factors, deviations can also be caused by factors related to the tool itself (e.g., impacts or vibrations). Therefore, before starting work, check the leveling accuracy.

If during one of the checks the measuring tool exceeds the maximum permissible deviation, it must be repaired by an authorized Bosch service center for power tools.

Checking the accuracy of the horizontal leveling

For the check, you need a free measuring area of 5 m on a firm surface between two walls A and B.

Mount the measuring tool close to wall A on a tripod or place it on a firm, level surface. Switch on the measuring tool.

266 | Bulgarian

Aim the laser beam at the nearby wall A and allow it to level. Mark the center of the laser point on the wall (point I).

• Rotate the measuring tool by 180°, allow it to level and mark the center of the laser beam on the opposite wall B (point II).
• Place the measuring tool – without rotating it – close to wall B, switch it on and allow it to level.

• Align the laser beam in height (using the tripod or by placing shims) so that the center of its beam exactly coincides with the previously marked point II on wall B.

Rotate the measuring tool 180°, without changing the height. Allow it to level and mark the center of the laser beam on wall A (point III). Ensure that point III is as vertically above or below point I as possible. - The difference d between the two marked points I and III on wall A gives the actual height deviation of the measuring tool along the longitudinal axis.

At a distance of 2 × 5 m = 10 m, the maximum permissible deviation is:

10 m × ±0.35 mm/m = ±3.5 mm. Therefore, the difference d between points I and III must be no more than 3.5 mm.

GPL 5 G: Repeat the procedure for the two lateral laser beams, which run along the transverse axis of the measuring tool. To do this, rotate the measuring tool 90° counterclockwise before starting the measurement.

Checking the plumb accuracy

For the check, you need a free measuring distance on a firm base with a distance of approx. 2.5 m between floor and ceiling.

• Place the measuring tool on the floor. Switch on the measuring tool and allow it to level. Extend the telescopic rod (3) so that the lower laser point is visible on the floor. Allow the measuring tool to level automatically.

- Mark the center of the upper laser point on the ceiling (point I). Also mark the center of the lower laser point on the floor (point II).

• Rotate the measuring tool 180°. Position it so that the center of the lower laser point is exactly on the marked point II. Allow the measuring tool to level automatically. Mark the center of the upper laser point (point III).
• The difference d between the two marked points I and III on the ceiling gives the actual height deviation of the measuring tool.

The maximum permissible deviation can be calculated as follows: double the distance between floor and ceiling × 0.35 mm/m

Example: At a distance between floor and ceiling of 2.5 m, the maximum deviation may be

2 × 2.5 m × ±0.35 mm/m = ±1.75 mm. Therefore, points I and III may be no more than 1.75 mm apart.

Working instructions

Rotate the device, keeping the center of the laser beam in place.

The laser beam changes the distance.

Working with the stand (accessory)

Using the stand provides stability and adjustable height for mounting the measuring tool. Place the measuring tool with the 1/4" stand mount (4) onto the stand screw (11) or a conventional tripod. Tighten the measuring tool with the stand screw.

Before switching on the measuring tool, roughly align the stand.

Secure the stand column (see fig. A-B) with the locking screw.

With the integrated rotating column (3) you can secure the measuring tool to magnetizable materials.

Clean the contact surfaces of the rotating column before securing it to surfaces. Through the holes, the magnets (7) can be reached.

Before switching on the measuring tool, roughly align the rotating column (3).

Turn the measuring tool on the rotating column (3) to perform a laser line or to transfer heights with the laser line. Leave the measuring tool free to rotate on the column if you are transporting it (see fig. B).

Laser viewing glasses (accessory)

The laser viewing glasses filter out ambient light. This makes the laser beam appear brighter.

Do not use the laser viewing glasses (accessory) as protective goggles. The laser viewing glasses are used for better recognition of the laser beam; they do not protect against laser radiation.

270|Bulgarian

Do not use the laser viewing glasses (accessory) as sunglasses or while driving. The laser viewing glasses do not provide full UV protection and reduce color perception.

Working examples (see C-E)

Examples of how to use the measuring tool can be found on the page with the figures.

Technical data

Inserting/Replacing the battery

For operation with the measuring tool, the use of alkaline-manganese batteries is recommended.

Turn the rotating knob for fine adjustment (3) so that the battery compartment cover (6) can be removed.

Open the battery compartment cover (6), press the locking mechanism (5) upward, and remove the battery compartment cover. Insert the batteries.

Pay attention to the polarity as indicated on the inside of the battery compartment.

Place the battery compartment cover (6) back on and press it firmly into the designated place on the locking mechanism (5).

If the batteries weaken, the brightness of the laser points may decrease. When the batteries are almost exhausted, the laser points flash 5 times per minute.

When the batteries are empty, the laser points flash faster before the measuring tool switches off.

Always replace all batteries at the same time. Use only batteries from one manufacturer and with the same capacity.

276 Macedonian

If you do not use the measuring tool for a long time, remove the batteries.

When stored for a long time in the measuring tool, the batteries may corrode and discharge.

Operation

Starting Operation

Protect the measuring tool from moisture and direct sunlight. Do not expose the measuring tool to extreme temperatures or humidity. Do not leave it in a car for a long time. At high temperatures or humidity, let the measuring tool cool down first and perform a check for accuracy before continuing work (see "Checking the Accuracy of the Measuring Tool", page 277). At extreme temperatures or humidity, the accuracy of the measuring tool may be impaired. Avoid impacts and dropping of the measuring tool. After severe external influences on the measuring tool, always perform an accuracy check before continuing work (see "Checking the Accuracy of the Measuring Tool", page 277). Switch off the measuring tool during transport. When switching off, the oscillation unit is locked, which would otherwise be damaged during intense movement.

Switching On/Off

To switch on the measuring tool, press the on/off switch (2) to the ON position. After switching on, the measuring tool emits a laser line from the outlet openings (1). Do not point the laser beam at persons or animals and do not look directly into it, even from a distance.

To switch off the measuring tool, press the on/off switch (2) to the OFF position. When switching off, the oscillation unit is locked.

Remove the protective cap from the measuring device and switch it on. Other devices may be affected by the laser beam.

When lowering the device, the maximum permissible operating temperature of 45°C is excluded for laser protection. Once it cools down, the measuring device is ready for operation again and can be switched on again.

Automatic switch-off

The measuring device switches off automatically after 60 minutes of operation.

The automatic switch-off is reset 60 minutes before the measuring device is switched off, provided the device is switched on again (the laser points flash continuously).

Automatic levelling

Place the measuring device on a horizontal surface, switch it on, and attach it to the tripod (11).

To use the lower laser point, turn the measuring device on the rotating mount (3) so that the laser point is visible below.

Switch on, the automatic levelling automatically compensates for irregularities within the self-levelling range of ±4°. Levelling is complete when the laser points light up continuously and no longer flash.

If automatic levelling is not possible, e.g. because the surface on which the measuring device is standing deviates by more than 4° from the horizontal, the laser points flash continuously and quickly.

In such a case, place the measuring device horizontally and wait for the self-levelling. Then the measuring device will be within the self-levelling range of ± 4° and the laser points will light up continuously.

Vibration or a change in position during operation causes the measuring device to level itself again automatically. After re-levelling, check the position of the horizontal and vertical laser points in relation to the reference points to avoid errors when positioning the measuring device.

The ambient temperature has the greatest influence. In particular, temperature differences that occur from the bottom to the top can affect the laser beam.

Place the measuring tool on the floor at the distance from the wall, or mount it on a tripod. Always mount it on a stationary surface at a distance of 20 m from the wall. If possible, place the measuring tool in the middle of the working area.

Besides the wall influences, the service can also affect the tool's accuracy (e.g., if it has been dropped). Therefore, before each use, check the leveling accuracy.

If the measuring tool exceeds the maximum deviation during one of the tests, it must be repaired by the Bosch after-sales service.

Checking the horizontal leveling accuracy

For the check, you need a free measuring distance of 5 m on a firm surface between two walls A and B.

Mount the measuring tool close to wall A on a tripod, or place it on a firm, flat surface. Switch on the measuring tool.

Aim the horizontal laser beam, which runs parallel to the longitudinal axis of the measuring tool, at the close wall A. Allow the measuring tool to level in. Mark the center of the laser point on wall A (point I).

Rotate the measuring tool by 180°, allow it to level in, and mark the center of the laser point on the opposite wall (point II). Place the measuring tool – without rotating it – close to wall B, switch it on, and allow it to level in.

• Align the measuring tool in height (using the tripod or by placing shims underneath) so that the center of the laser point exactly hits the previously marked point II on wall B.

Rotate the measuring tool by 180° without changing the height. Allow it to level in and mark the center of the laser point on wall A (point III). Make sure that point III is as vertically above or below point I as possible. The difference d of the two marked points I and III on wall A indicates the actual deviation of the measuring tool from the horizontal plane.

On the measuring distance of 2 x 5 m = 10 m, the maximum allowable deviation is: 10 m x ±0.35 mm/m = ±3.5 mm. The difference d between points I and III may therefore be at most 3.5 mm.

GPL 5 G: Repeat the measuring procedure for the two sides and the laser beam that runs along the transverse axis of the measuring tool. Rotate the measuring tool by 90° before starting the measuring procedure in the direction opposite to the clockwise direction.
