APERTURE

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.

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.

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

English | 9

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-observance 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.

Remote Control

Read and observe all instructions. The integrated protections in the measuring tool may be compromised if the measuring tool is not used in accordance with the instructions provided. 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.

Operation

Starting Operation of the Rotational Laser Level

Protect the measuring tool against moisture and direct sun light.

Do not subject the measuring tool to extreme temperatures or variations in temperature. As an 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 heavy impact to or dropping down of the measuring tool. After severe exterior effects to the measuring tool, it is recommended to carry out an accuracy check (see “Levelling Accuracy of the Rotational Laser Level”, page 13) each time before continuing to work.

Switch the measuring tool off before transporting it.

This will save energy and prevent laser beams from being emitted accidentally.

Setting Up the Measuring Tool

Horizontal position

Vertical position

Set up the measuring tool on a sturdy surface in the horizontal or vertical position; mount it on a tripod 31 or to the wall mount with alignment unit 33.

Due to the high levelling accuracy, the measuring tool reacts sensitively to ground vibrations and position changes. Therefore, pay attention that the position of the measuring tool is stable in order to avoid operational interruptions due to relevelling.

Switching On and Off

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). Immediately after switching on, the measuring tool sends out the vertical plumb beam 9 and the variable laser beam 6.

For switching on the measuring tool, press the On/Off button 4. The indicators 1, 3 and 12 light up briefly. The measuring tool immediately starts the automatic levelling. During the levelling, the levelling indicator 3 lights up green and the laser flashes in point operation.

The measuring tool is levelled in as soon as levelling indicator 3 lights up green continuously and the laser beam is steady. After the levelling is completed, the measuring tool automatically starts in rotational operation.

With the operating mode buttons 5 and 11, the operating modes can already be specified during levelling in (see “Operating Modes of the Rotational Laser Level”, page 12). In this case, the measuring tool starts in the set operating mode upon completion of levelling in.

	Bosch Power Tools				1 609 92A 28U | (1.2.17)

OBJ_BUCH-1492-005.book Page 12 Wednesday, February 1, 2017 7:09 AM

12 | English

To switch off the measuring tool, press the On/Off button 4 again.

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.

To save the batteries, the measuring tool is automatically switched off when not within the self-levelling range for more than 2 h or when the shock warning is actuated for more than 2 h (see “Automatic Levelling of the Rotational Laser Level”, page 13). Reposition the measuring tool and switch it on again.

Starting Operation of the Remote Control

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.

Set up the measuring tool in such a manner that the signals of the remote control can directly reach one of the reception lenses 7. 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.

After pressing a button on the remote control, the illuminated operation indicator 24 indicates that a signal was sent out.

Switching the measuring tool on/off with the remote control is not possible.

Operating Modes of the Rotational Laser Level

Overview

All three operating modes are possible with the measuring tool in horizontal and vertical position.

Rotational Operation

Rotational operation is especially recommended when using the laser receiver. You can select between different rotational speeds.

Line Operation

In this operation mode, the variable laser beam moves within a limited aperture angle. This increases the visibility of the laser beam in comparison to rotational operation. You can select between different aperture angles.

Point Operation

This operation mode enables the best visibility of the variable laser beam. As an example, it is used for easy projecting of heights or checking building lines.

Rotational Operation (150/300/600 min-1)

Each time after switching on, the measuring tool is in rotational operation mode with average rotational speed.

To switch from line operation to rotational operation, press the rotational operation button 5 or button 19 on the remote control. Rotational operation starts with average rotational speed.

To change the rotational speed, press the rotational operation button 5 or button 19 again until the requested speed is reached.

When working with the laser receiver, the highest rotational speed should be set. When working without laser receiver, reduce the rotational speed for improved visibility of the laser beam and use the laser viewing glasses 32.

Line Operation, Point Operation (10 °/25 °/50°, 0 °)

To switch to line or point operation, press the line operation button 11 or button 20 on the remote control. The measuring tool switches to line operation with the smallest aperture angle.

To change the aperture angle, press the line operation button 11 or button 20 on the remote control. The aperture angle is increased in two steps; at the same time, the rotational speed is increased with each step. When pressing the line operation button a third time, the measuring tool switches to point operation after brief post-pulsation. Pressing the line operation button again takes you back to line operation with the smallest aperture angle.

Note: Due to inertia, it is possible for the laser to slightly move beyond the end point of the laser line.

Rotating the Laser Line/Laser Dot or the

Rotational Plane (see figure A)

When the measuring tool is in the horizontal position, the laser line (in line operation) or the laser dot (in point operation) can be positioned within the rotational plane of the laser.

Rotation is possible by 360 °.

For this, manually turn the rotation head 10 to the desired position or use the remote control: Press button 22 to rotate in clockwise direction, and button 23 on the remote control to rotate in anticlockwise direction. In rotational operation, pressing the buttons has no effect.

	1 609 92A 28U | (1.2.17)				Bosch Power Tools

OBJ_BUCH-1492-005.book Page 13 Wednesday, February 1, 2017 7:09 AM

When the measuring tool is in the vertical position, it is possible to rotate the laser point, laser line or rotational plane around the vertical axis. Rotating is possible only within the self-levelling range (5 ° leftwards or rightwards) and only with the remote control.

Press button 22 on the remote control to rotate in clockwise direction, and button 23 on the remote control to rotate in anticlockwise direction.

Automatic Levelling of the Rotational Laser Level

Overview

After switching on, the measuring tool automatically detects the horizontal or vertical position. To change between the horizontal and vertical position, switch the measuring tool off, reposition it and switch on again.

After switching on, the measuring tool checks the horizontal and vertical position and automatically levels out any unevenness within the self-levelling range of approx. 8 % (5 °).

When the measuring tool is inclined by more than 8 % after switching on or after a position change, levelling in is no longer possible. In this case, the rotor is stopped, the laser flashes and levelling indicator 3 continuously lights up red. Reposition the measuring tool and wait for it to re-level. Without repositioning, the laser is automatically switched off after

2 minutes and the measuring tool after 2 hours.

When the measuring tool is levelled in, it continuously checks the horizontal and vertical position. Automatic re-levelling takes place after position changes. To avoid faulty measurements, the rotor stops during the levelling process, the laser flashes and the levelling indicator 3 flashes green.

Shock-warning Function

The measuring tool has a shock-warning function; after position changes or shock to the measuring tool, or in case of ground vibrations, it keeps the measuring tool from levelling in at changed heights, and thus prevents vertical errors.

To switch on the shock-warning function, press the shockwarning button 2. The shock-warning indicator 1 continuously lights up green, and the shock-warning function is activated after 30 seconds.

When the levelling-accuracy range is exceeded after a position change of the measuring tool or when heavy ground vibrations are detected, the shock-warning function is actuated: The rotation is stopped, the laser flashes, the levelling indicator 3 goes out and the shock-warning indicator 1 flashes red. The current operating mode is stored.

After the shock warning has actuated, press the shockwarning button 2 on the measuring tool or the shock-warning reset button 21 on the remote control. The shock-warning function is restarted and the measuring tool starts the levelling. As soon as the measuring tool is levelled in (levelling indicator 3 continuously lights up green), it starts in the stored operating mode. Now, check the height of the laser beam with a reference point and correct the height, if required.

English | 13

When, after the shock-warning function has actuated, the function is not restarted by pressing button 2 on the measuring tool or the shock-warning reset button 21 on the remote control, the laser is automatically switched off after 2 minutes and the measuring tool after 2 hours.

To switch off the shock-warning function, press shockwarning button 2 once, or, when the shock warning is actuated (shock-warning indicator 1 flashing red) press it twice. When the shock-warning function is shut off, the shockwarning indicator 1 goes out.

The shock-warning function cannot be switched on or off with the remote control; it can only be restarted after having actuated.

Levelling Accuracy of the Rotational Laser Level

Influences on Accuracy

The ambient temperature has the greatest influence. Especially temperature differences occurring from the ground upward can divert the laser beam.

The deviations play a role in excess of approx. 20 m measuring distance and can easily reach two to four times the deviation at 100 m.

Because the largest difference in temperature layers is close to the ground, the measuring tool should always be mounted on a tripod when measuring distances exceeding 20 m. If possible, also set up the measuring tool in the centre of the work area.

Accuracy Check of the Measuring Tool

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

For the accuracy check, an unobstructed measuring distance of 20 m on firm ground between two walls A and B is required. With the measuring tool in the horizontal position, a transit measurement is to be carried out across both axes X and Y (both positive and negative) (altogether 4 complete measurements).

–Mount the measuring tool in the horizontal position onto a tripod 31 (accessory) or place it on a firm and level surface near wall A. Switch the measuring tool on.

–Align the height of the measuring tool (using the tripod or by underlaying, if required) in such a manner that the centre point of the laser beam is projected exactly against the previously marked point II on wall B.

A

B

180°

–Rotate the measuring tool by 180 ° without changing the height. Allow it to level in and mark the centre point of the laser beam on wall A (point III). Take care that point III is as vertical as possible above or below point I.

The difference d of both marked points I and III on wall A amounts to the actual deviation of the measuring tool for the measured axis.

Repeat the measuring procedure for the other three axes. For this, turn the measuring tool prior to each measuring procedure by 90 °.

–GRL 240 HV:

The maximum permitted deviation over the measuring section of 2 x 20 m = 40 m is as follows:

40 m x ± 0.2 mm/m = ± 8 mm.

The difference d between points I and III must therefore be maximum 16 mm in each of the four measuring procedures.

–GRL 250 HV/GRL 300 HV/GRL 300 HVG:

The maximum permitted deviation over the measuring section of 2 x 20 m = 40 m is as follows:

40 m x ± 0.1 mm/m = ± 4 mm.

The difference d between points I and III must therefore be maximum 8 mm in each of the four measuring procedures.

If the measuring tool should exceed the maximum deviation in any one of the four measuring procedures, have it checked at a Bosch after-sales service agent.

Working Advice

Always use the centre of the laser point for marking.

The size of the laser point changes with the distance.

Laser Viewing Glasses (Accessory)

The laser viewing glasses filter out ambient light. This enhances the laser visibility for the eye.

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.

Working with the Laser Receiver (Accessory)

Under unfavourable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser beam 29.

When working with the laser receiver, select rotational operation with the highest rotational speed.

Before working with the laser receiver, read and observe the laser receiver operating instructions.

Working with the Remote Control (Accessory)

While pressing the operator buttons, the measuring tool can be brought out of alignment so that the rotation is briefly stopped. This effect is avoided when using the remote control.

Reception lenses 7 for the remote control are located on three sides of the measuring tool, among other locations above the control panel on the front side.

Working with the Tripod (Accessory)

The measuring tool is equipped with a 5/8" tripod mount for horizontal operation on a tripod. Place the measuring tool via the tripod mount 15 onto the 5/8" male thread of the tripod and screw the locking screw of the tripod tight.

On a tripod 31 with a measuring scale on the elevator column, the height difference can be adjusted directly.

OBJ_BUCH-1492-005.book Page 15 Wednesday, February 1, 2017 7:09 AM

Working with Wall Mount/Alignment Unit (Accessory) (see figure B)

You can also mount the measuring tool to the wall mount with alignment unit 33. For this, screw the 5/8" screw 36 of the wall mount into the tripod mount 15 of the measuring tool.

Mounting to a wall: Mounting to a wall is recommended, e. g., for work above the elevation height of tripods or for work on unstable surfaces and without tripod. For this, fasten the wall mount 33, with the measuring tool mounted, as vertical as possible to a wall.

For mounting to the wall, you can either fasten the wall mount 33 with fastening screw 34 to a lath (width maximal 8 mm) or hang it up with two hooks.

Mounting on a tripod: The wall mount 33 can also be screwed onto a tripod with the tripod mount on the back side. This method of fastening is especially recommended for work where the rotational plane is to be aligned with a reference line.

With the alignment unit, the mounted measuring tool can be moved vertically (when mounted to the wall) or horizontally (when mounted to a tripod) within a range of approx. 16 cm. For this, loosen screw 35 on the alignment unit, move the measuring tool to the desired position, and retighten screw 35 again.

Working with the Ceiling Measurement Plate (see figure B)

As an example, the ceiling measurement plate 38 can be used for easy height adjustment of drop ceilings. Fasten the ceiling measurement plate with the magnetic holder, e. g., to a beam.

The reflecting half of the ceiling measurement plate improves the visibility of the laser beam in unfavourable conditions; the laser beam can also be seen from the rear side through the transparent half.

Working with the Laser Target Plate (Accessory) (see figure C)

With the laser target plate 37, the laser mark can be projected on the ground/floor or against a wall. With the magnetic holder, the laser target plate can also be fastened to ceiling constructions.

With the zero field and the scale, the offset or drop to the required height can be measured and projected at another location. This eliminates the necessity of precisely adjusting the measuring tool to the height to be projected.

The laser target plate 37 has a reflecting coating which improves the visibility of the laser beam from a larger distance or in case of strong sun rays. The luminosity can be recognized only if you look to the laser target plate in parallel to the laser beam.

English | 15

Working with the Measuring Rod (Accessory) (see figure J)

For checking irregularities or projecting gradients, it is recommended to use the measuring rod 30 together with the laser receiver.

A relative millimetre scale ( ±50 cm) is marked on the top of the measuring rod 30. Its zero height can be preset at the bottom of the elevator column. This allows for direct reading of deviations from the specified height.

Work Examples

Projecting/Checking Heights (see figure C)

Position the measuring tool in the horizontal position onto a firm support or mount it onto a tripod 31 (accessory).

Working with tripod: Align the laser beam to the requested height. Project or check the height at the target location.

Working without tripod: Determine the height difference between the laser beam and the height at the reference point with the laser target plate 37. Project or check the measured height difference at the target location.

Parallel Alignment of a Plumb Beam/Projecting Right Angles (see figure D)

When right angles are to be projected or when partitions are to be aligned, the plumb beam 9 must be aligned parallel, meaning at the same distance to a reference line (e. g. a wall).

For this, set up the measuring tool in the vertical position and position it in such a manner that the plumb beam runs approximately parallel to the reference line.

For exact positioning, measure the clearance between plumb beam and reference line directly on the measuring tool with help of the laser target plate 37. Measure the clearance between plumb beam and reference line again as far away as possible from the measuring tool. Align the plumb beam in such a manner that it has the same clearance to the reference line as when measured directly at the measuring tool.

The right angle to the plumb beam 9 is indicated by the variable laser beam 6.

Indicating a Plumb Line/Vertical Plane (see figure E)

To indicate a plumb line or a vertical plane, set up the measuring tool in the vertical position. When the vertical plane is supposed to run at a right angle to a reference line (e. g. a wall), then align the plumb beam 9 with this reference line.

The plumb line is indicated by the variable laser beam 6.

Turning the Rotational Plane when in the Vertical Position (see figure F)

To align the vertical laser line or the rotational plane against a reference point on a wall, set up the measuring tool in the vertical position, and roughly align the laser line or the rotational plane with the reference point. For precise alignment with the reference point, press button 22 (clockwise rotation) or button 23 on the remote control (anticlockwise rotation).

Working without Laser Receiver (see figure G)

Under favourable light conditions (dark environment) and for short distances, it is possible to work without the laser receiver. For better visibility of the laser beam, either select line operation, or select point operation and manually rotate the rotation head 10 to the target location.

Working with the Laser Receiver (see figure H)

Under unfavourable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser beam. When working with the laser receiver, select rotational operation with the highest rotational speed.

Measuring Over Long Distances (see figure I)

When measuring over long distances, the laser receiver must be used to find the laser beam. In order to reduce interferences, the measuring tool should always be set up in the centre of the work surface and on a tripod.

Working Outdoors (see figure J)

The laser receiver should always be used when working outdoors.

When working on unstable ground, mount the measuring tool onto the tripod 31. Activate the shock-warning function in order to avoid faulty measurements in case of ground vibrations or shock to the measuring tool.
