Frequently Asked Questions - GLL 3-50 Professional BOSCH

How to turn the GLL 3-50 Professional on and off?

Press the on/off switch located on the side. A long press turns the device off. The green indicator light indicates that self-leveling is active.

What to do if the laser lines are weak or flashing?

This usually indicates weak batteries. Replace both AA batteries with new ones. If the problem persists, the device may be outside its leveling range (tilt > 4°). Place it on a more level surface.

How to use the magnetic bracket?

Attach the bracket to a clean metal surface. The bracket can rotate and tilt. Screw the device onto the bracket via the 1/4" thread. You can also attach the bracket to a tripod.

What is the accuracy of the device?

The leveling accuracy is ± 0.3 mm per meter. This means that at 10 m, the maximum deviation is 3 mm.

Can I use the device outdoors?

Yes, but the range is reduced in direct sunlight. Use a Bosch laser receiver to extend the range up to 30 m. The device is splash-proof (IP54).

How to check calibration?

Place the device on a tripod 20 m from a wall. Draw the horizontal line. Rotate the device 180° and draw a second line. If the two lines are more than 3 mm apart, the device must be recalibrated by a Bosch authorized service center.

What does the flashing red indicator mean?

The red indicator flashes when the device is in leveling mode or when the leveling range is exceeded. Wait until the indicator becomes steady green. If it remains red, the device is too tilted.

How to clean the laser optics?

Use a soft dry cloth. Never use chemicals or abrasive cloths. For stubborn stains, slightly dampen the cloth with water.

What type of batteries to use?

Use alkaline AA (LR6) 1.5 V batteries. You can also use rechargeable NiMH AA (1.2 V) batteries, but the operating time will be reduced.

Where can I find spare parts?

AA batteries are commercially available. For other parts (bracket, case, etc.), contact Bosch customer service or an authorized dealer. Repairs must be carried out by an authorized center.

Assembly

Inserting/Changing the batteries

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

To open the battery compartment cover (7), pull the locking mechanism (8) and lift the battery compartment cover. Insert the batteries.

When doing so, ensure that the polarity is correct and corresponds to the diagram on the battery compartment cover.

If the battery warning (5) flashes red, the batteries must be replaced.

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.

Working with the rotating platform

You can use the rotating platform (16) to rotate the measuring tool 360° around a central, always visible plumb point. This enables you to set up the laser lines precisely, without having to change the position of the measuring tool.

Place the measuring tool with the guide groove (13) on the guide rail (17) of the rotating platform (16) and slide the measuring tool as far as it will go onto the platform.

To disconnect the measuring tool, pull it off the rotating platform in the opposite direction.

To adjust the height of the rotating platform, unscrew and remove the locking screw (14) of one of the telescopic legs. Lock the telescopic leg by tightening the locking screw. Repeat the process for the other two telescopic legs.

If the measuring tool is mounted on the rotating platform (16), you can use the fine adjustment screw (15) to align vertical laser lines precisely with reference points.

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 16).

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 16).

▶ 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 (12) to the on position (for working with the pendulum lock) or to the on position (for working with automatic levelling). 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 (12) 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 40^ 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.

Deactivating the automatic shut-off function

If no button on the measuring tool is pressed for approx. 30 min, the measuring tool will automatically switch itself off to preserve battery life.

To deactivate the automatic shut-off function, hold down the laser mode button (4) for at least 3 s when switching on the measuring tool. The laser beams will flash briefly after 3 s if the automatic shut-off function is deactivated.

To activate the automatic shut-off function, switch the measuring tool off and on again (without holding down the laser mode button (4)).

Operating Modes

The measuring tool has several operating modes, which you can switch between at any time:

- Horizontal mode combined with vertical mode: Generates one horizontal and two orthogonal vertical laser lines

- Horizontal mode: Generates one horizontal laser line

- Cross-line mode: Generates one horizontal and one vertical laser line

- Vertical mode: Generates two orthogonal vertical laser lines

In all operating modes, a plumb point is projected onto the floor.

Once switched on, the measuring tool is in horizontal mode combined with vertical mode. To change the operating mode, press the laser mode button (4).

All operating modes can be selected with both automatic levelling or the pendulum lock.

16 | English

Receiver Mode

Receiver mode must be activated when working with the laser receiver (23), regardless of which operating mode is selected.

In receiver mode, the laser lines flash at a very high frequency, enabling them to be detected by the laser receiver (23).

To switch on receiver mode, press the receiver mode button (3). The receiver mode indicator (2) will light up green.

When receiver mode is switched on, the laser lines are less visible to the human eye. Therefore, switch receiver mode off by pressing the receiver mode button (3) again to work without a laser receiver. The receiver mode indicator (2) will go out.

Automatic Levelling

Working with Automatic Levelling

Position the measuring tool on a level, firm surface or attach it to the rotating platform (16) or the tripod (21).

For work with automatic levelling, slide the on/off switch (12) to the "On" position.

The automatic levelling function automatically levels irregularities within the self-levelling range of ±4^ . The levelling is finished as soon as the laser beams stop flashing.

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 beams will begin to flash quickly.

Place the measuring tool in a horizontal position and wait for self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4^ , the laser beams will light up continuously.

In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again.

Upon re-levelling, check the position of the horizontal or vertical laser line with regard to the reference points to avoid errors by moving the measuring tool.

Working with the pendulum lock

For work with the pendulum lock, slide the on/off switch (12) to the "On" position. The laser lines continuously flash slowly when working with the pendulum lock.

For work with the pendulum lock, the automatic levelling is switched off. You can hold the measuring tool freely in your hand or place it on a sloping surface. This means that the laser lines are no longer levelled and no longer necessarily run perpendicular to one another.

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.

In order to minimise thermal influences resulting from heat rising from the floor, it is recommended that you use the measuring tool on a tripod. 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.

First check the height accuracy and levelling accuracy of the horizontal laser line, then the levelling accuracy of the vertical laser line.

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 Height Accuracy of the Horizontal Line

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, level surface. Switch on the measuring tool. Select cross-line mode with automatic levelling.

- Aim the laser at the closer wall A and allow the measuring tool to level in. Mark the middle of the point at which the laser lines cross on the wall (point I).

- Turn the measuring tool 180^ , allow it to level in and mark the point where the laser lines cross 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 point where the laser lines cross exactly hits the previously marked point II on wall B.

• Turn the measuring tool 180^ without adjusting the height. Aim it at wall A such that the vertical laser line runs through the already marked point I. Allow the measuring tool to level in and mark the point where the laser lines cross on wall A (point III).
• The discrepancy d between the two marked points I and III on wall A reveals the actual height deviation of the measuring tool.

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

10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points I and III must therefore amount to no more than 3 mm.

Checking the Level Accuracy of the Horizontal Line

For this check, you will need a free area of 5 × 5 m.

- Mount the measuring tool in the middle between walls A and B on a tripod, or place it on a firm, level surface. Select horizontal mode with automatic levelling and allow the measuring tool to level in.

- At a distance of 2.5 m from the measuring tool, mark the centre of the laser line on both walls (point I on wall A and point II on wall B).

• Set up the measuring tool at a 5 m distance and rotated by 180^ 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 of the laser line exactly hits the previously marked point II on wall B.
• Mark the centre of the laser line on wall A as point III (vertically above or below point I).
• The discrepancy d between the two marked points I and III on wall A reveals the actual horizontal deviation of the measuring tool.

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

10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points I and III must therefore amount to no more than 3 mm.

Checking the Level Accuracy of the Vertical Line

For this check, you will need a door opening (on solid ground) which has at least 2.5 m of space either side of the door.

- Place the measuring tool 2.5 m away from the door opening on a firm, flat surface (not on a tripod). Select cross-line mode with automatic levelling. Aim the vertical laser

18 | English

line at the door opening and allow the measuring tool to level in.

- Mark the centre of the vertical laser line on the floor of the door opening (point I), 5 m away on the other side of the door opening (point II) and on the upper edge of the door opening (point III).

• Rotate the measuring tool 180^ and position it on the other side of the door opening, directly behind point II. Allow the measuring tool to level in and align the vertical laser line in such a way that its centre passes through points I and II exactly.
• Mark the centre of the laser line on the upper edge of the door opening as point IV.
• The discrepancy d between the two marked points III and IV reveals the actual vertical deviation of the measuring tool.
• Measure the height of the door opening.

You can calculate the maximum permitted deviation as follows:

Doubled height of the door opening × 0.3 mm/m Example: At a door opening height of 2 m, the maximum deviation amounts to

2 × 2 m × ± 0.3 mm/m = ± 1.2 mm . The points III and IV must therefore be no further than 1.2 mm from each other.

Checking Plumb Accuracy

For this check, you will need a clear measuring space on firm ground with a distance of approx. 5 m between the floor and the ceiling.

- Mount the measuring tool onto the rotating platform (16) and place it on the floor. Select vertical mode with automatic levelling and allow the measuring tool to level in.

- Mark the centre of the top point of intersection of the laser lines on the ceiling (point I). Also mark the centre of the plumb point on the floor (point II).

• Turn the measuring tool by 180^ . Position it so that the centre of the plumb point falls onto the marked point II. Allow the measuring tool to level in. Mark the centre of the top point of intersection of the laser lines (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 × 0.6 mm/m Example: At a floor-to-ceiling distance of 5 m, the maximum deviation amounts to

2 × 5 m × ± 0.6 mm/m = ± 6 mm . The points I and III must therefore be no further than 6 mm from each other.

Working Advice

▶ Only the centre of the laser point or laser line must be used for marking. The size of the laser point/the width of the laser line changes depending on the distance.

Working with the Laser Target Plate

The laser target plate (19) improves visibility of the laser beam in unfavourable conditions and at greater distances. The reflective surface of the laser target plate (19) improves visibility of the laser line. The transparent surface enables the laser line to be seen from behind the laser target plate.

Working with the Tripod

A tripod offers a stable, height-adjustable support surface for measuring. Place the measuring tool with the 1/4" tripod mount (6) on the thread of the tripod (21) or a conventional camera tripod. Use the 5/8" tripod mount (9) to secure the measuring tool on a conventional building tripod. Tighten the measuring tool using the locking screw of the tripod. Roughly align the tripod before switching on the measuring tool.

Working with the Laser Receiver (see figure E)

Use the laser receiver (23) to improve detection of the laser lines in adverse lighting conditions (bright environment, direct sunlight) and over greater distances. When working with the laser receiver, switch on receiver mode (see "Receiver Mode", page 16).

Laser Goggles

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 A–F)

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

Maintenance and Service

Maintenance and Cleaning

Keep the measuring tool clean at all times. Never immerse the measuring tool in water or other liquids. Wipe off any dirt using a damp, soft cloth. Do not use any detergents or solvents.

The areas around the outlet aperture of the laser in particular should be cleaned on a regular basis. Make sure to check for lint when doing this.
