natural_image
Line drawing of a portable electronic device with front panel and control panel (no text or symbols)Point Operation (GRL2000-40HV)
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.
natural_image
Technical line drawing of a mechanical device with no visible text or symbolsLine Operation (GRL2000-40HV)
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.
Rotation Mode (GRL2000-40H)
Each time after switching on, the laser tool is in rotational operation mode with standard rotational speed (600 min ^-1 ). Adjusting the speed for the GRL2000-40H is not possible.
Rotation Mode (GRL2000-40HV)
Each time after switching on, the laser tool is in rotational operation default rotational speed (300 min ^-1 ).
Rotational operation starts at default rotational speed (300 min ^-1 ).
To change the rotational speed, press the rotational operation button 3 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 24.
Point Operation (GRL2000-40HV)
To switch to point operation press the rotational operation button 3 until you reach the desired setting.
Note: Due to inertia, it is possible for the laser to make a few revolutions before point operation is set.
Line Operation (10°/25°/50°) (GRL2000-40HV)
To switch to line operation, press the line operation button 13. The laser tool switches to line operation with
the smallest aperture angle.
To change the aperture angle, press the line operation button 13 until you reach the desired setting.
Note: Due to inertia, it is possible for the laser to slightly move beyond the end point of the laser line.
To position the laser line or the laser point within the rotational plane, press the button 4 or 12 to the requested position or use the remote control 20.
To return to rotational operation press the rotational operation button 3.
Manual Operation and Manual Slope
The automatic leveling of the laser level can be switched off (manual operation):
– in the horizontal position for both axes independently of each other
- in the vertical position for the X-axis (the Y-axis cannot be leveled in the vertical position) (GRL2000-40HV only).
The X-axis and Y-axis are marked on top of the GRL.

If one of both axes is in manual operation (respective leveling indicator LED is continuously red) press the button for dual-axis slope operation 2 to additionally tilt the axis, which was last set to manual operation. Press the button for dual-axis slope operation 2 again to adjust/tilt the other axis.
To reset both axes to automatic leveling press the button for dual-axis slope operation 2 as many times as necessary - until both X and Y leveling indicator LEDs 5 start flashing green (leveling still in process) or light up green.
Manual Operation and Manual Slope in Vertical Mode (GRL2000-40HV only)
In vertical mode only the X-axis will be reset to automatic leveling (the Y-axis cannot be leveled in the vertical position).
The Y leveling indicator LED 5 is off by default, unless it has been tilted/moved from its default position.
Turning the Rotational Plane in the Vertical Position
When the laser level is in the vertical position, it is possible to rotate the rotational plane around the X-axis for easy sighting out or parallel alignment in a range of ± 8% . To activate the function, press the button for dual-axis slope
operation 2 on the laser level twice or the button for dual-axis slope operation 10a on the remote control followed by the Y lower/upper direction button. The Y leveling indicator LED 5 will start flashing red. Press the Y lower/upper direction button 4 or 12 until the required position is reached.
Leveling Accuracy
Automatic Leveling
Overview
After switching on, the laser tool automatically detects the horizontal or vertical position. To change between horizontal and vertical position, switch the laser tool off, reposition it and switch on again.
After switching on, the laser tool checks the horizontal and vertical position and automatically levels out any unevenness within the self-leveling range of approx. 8% (4.6°).
When the laser tool is inclined by more than 8% after switching on or after a position change, leveling in is no longer possible. In this case, the rotor is stopped, the laser off and leveling indicator 5 continuously lights up red. Switch the laser tool off, reposition it, switch it on again and wait for it to re-level.
When the laser tool is leveled automatic re-leveling takes place after position changes. The rotor stops during the leveling process, the laser beam is off, and the leveling indicator 5 flashes green.
Shock-warning Function
The laser tool has a shock-warning function; after position changes or shock to the laser tool, or in case of ground vibrations, it prevents the laser tool from leveling at changed heights, and thus prevents vertical errors.
The shock warning function is ON by default every time the laser tool is switched on. ADS is active 30 seconds after device is leveled.
When the ADS is enabled the shock-warning indicator 11 is turned off.
After a position change or when heavy ground vibrations are detected, the shock-warning function is triggered: The rotation stops, the laser off, the leveling indicator 5 goes out, and the shock-warning indicator 11 flashes red.
The current operating mode is stored.
After the shock-warning function has been triggered, press the power button 1 shortly to reset it.
The shock-warning function is restarted and the laser tool starts leveling. As soon as the laser tool is leveled (leveling indicator 5 continuously lights up green), it starts in the stored operating mode. Now, align the laser beam with a reference point and correct the position, if required.
To switch off the shock-warning function, press the power button 1 shortly once, or, when the shock warning is triggered (shock-warning indicator 11 flashing red) press the power button shortly twice. When the shock-warning function is turned off, the shock warning indicator 11 lights up red.
Accuracy Check
Influences on Accuracy
The ambient temperature has the greatest influence on accuracy. Especially temperature differences occurring from the ground upward can divert the laser beam.
In addition to external influences, device specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the accuracy each time before beginning work.
The deviations play a role in excess of approx. 65 ft (20 m) distance and can easily reach two to four times the deviation at 330 ft (100 m).
Because the largest difference in temperature layers is close to the ground, the laser tool should always be mounted on a tripod when operating at distances exceeding 65 ft (20 m). If possible, also set up the laser tool in the center of the work area.
If the laser tool exceeds the maximum deviation in one of the four measuring procedures, have it checked by a Bosch customer service center.
WARNING It is the user's responsibility to periodically check the accuracy of the laser tool as work progresses. Always check the accuracy of the laser tool after it has been dropped or subjected to extreme temperatures and temperature variations.
Checking the Leveling Accuracy in the Horizontal Position
An unobstructed area of 100 ft (30 m) on a firm surface in front of a wall is required for the check. A complete accuracy check must be carried out for the X- and Y-axis.
- Mount the laser tool in the horizontal position onto a tripod or place it on a firm and level surface at a distance of 100 ft (30 m) to the wall. Switch the laser tool on.
- After the leveling, mark the center of the laser beam on the wall (point I).
text_image
I 100 ft (30 m)- Rotate the laser tool by 180^ , allow it to level in and mark the center point of the laser beam on the wall (point II). Make sure that point II is as vertical as possible above or below point I.
text_image
II d I 180°- The difference d of both marked points I and II on the wall results in the actual
height deviation of the laser tool for the measured axis.
Repeat the procedure for the other axis. For this, turn the laser tool by 90^ before starting.
The maximum permitted deviation over the recommended distance of 100 ft (30 m) is as follows:
$$ \begin{array}{l} 1 0 0 \mathrm{ft} \times \pm 1 / 1 6 \text { in } = \pm 1 / 1 6 \text { in } \ (3 0 \mathrm{m} \times \pm 0. 0 5 \mathrm{mm} = \pm 1. 5 \mathrm{mm}) \ \end{array} $$
The difference d between points I and II must therefore be maximum 1/8 in (3 mm) in each of the two accuracy check procedures.
Checking the Leveling Accuracy in the Vertical Position
An unobstructed area of 30 ft (10 m) on a firm surface in front of a wall is required for the check. Fasten a plumb bob rope to the wall.
- Mount the laser tool in the vertical position onto a tripod, or place it on a firm and level surface. Switch the laser tool on and allow it to level.
- Align the laser tool such that the laser beam impinges centrally on the plumb bob rope at the upper end. The difference d between laser beam and plumb bob rope at the bottom end of the rope results in the deviation of the laser tool to the vertical line.
text_image
30 ft (10 m) dThe maximum permitted deviation over a 30 ft (10 m) distance is as follows:
$$ \begin{array}{l} 3 0 \mathrm{ft} \times \pm 1 / 8 \text { in } = \pm 3 / 6 4 \text { in } \ (1 0 \mathrm{m} \times \pm 0. 1 \mathrm{mm} = \pm 1 \mathrm{mm}) \ \end{array} $$
The difference d must therefore be a maximum of 3/64 in (1 mm).
Calibration
X and Y Axes Calibration
- Make sure the laser level is turned off.
- Mount the laser level in the horizontal position on a tripod or a firm and level surface in front of a wall.

Applications
Indicating a Plumb Line/Vertical Plane (see figure B)
To indicate a plumb line or a vertical plane, set up the laser 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 8 with this reference line.
The plumb line is indicated by the variable laser beam 6.
Working without Laser Receiver (see figure C)
Under favorable light conditions (dark environment) and for short distances, it is possible to work without the laser receiver. For better visibility of the laser beam, select line operation or point operation, and rotate the beam with the direction buttons on the tool 4 and 12 or the remote control.
Working with the Laser Receiver (see figure D)
Under unfavorable 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.
Operating Over Long Distances (see figure E)
When operating over long distances, the laser receiver must be used to find the laser beam. In order to reduce interferences, the laser tool should always be set up in the center of the work area and on a tripod.
Working Outdoors (see figure F)
The laser receiver should always be used when working outdoors.
When working on unstable ground, mount the laser tool onto the tripod 21. Activate the shock-warning function in order to avoid errors in case of ground vibrations or shock to the laser tool.

Use with Accessories
Laser Viewing Glasses (Accessory)
WARNING
DO NOT use the laser viewing glasses as
safety goggles. The laser viewing glasses are used for improved visualization 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 color perception.
The laser viewing glasses filter out the ambient light. This makes the red light of the laser appear brighter for the eyes.
Working with the Laser Receiver (Accessory)
WARNING
Have your laser receiver serviced by a qualified
repair person using only identical replacement parts. This will ensure that the safety of the laser receiver is maintained.
Read and strictly observe the safety warnings in the operating instructions of the laser receiver.
Under unfavorable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver 23 for improved finding of the laser beam.
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 laser tool can be brought out of alignment so that the rotation is briefly stopped. This effect can be avoided by using the remote control 20.
Sensor for the remote control 9 for the remote control are located on four sides of the laser tool.
Working with the Tripod (Accessory)
The laser tool is equipped with a 5/8" tripod mount for horizontal operation on a tripod.
Place the laser tool via the tripod mount 16 onto the 5/8" male thread of the tripod and screw the locking screw of the tripod tight.
On a tripod with a measuring scale on the elevator column, the height difference can be adjusted directly.
Working with Wall Mount/Alignment Unit (Accessory) (see figure A)
You can also mount the laser tool to the wall mount with alignment unit 25. For this, screw the 5/8" screw 28 of the wall mount into the tripod mount 16 of the laser 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 25, with the laser tool mounted, as vertical as possible to a wall.
For mounting to the wall, you can either fasten the wall mount 25 with fastening screw 26 to a lath (width maximal 8 mm) or hang it up with two hooks.
Mounting on a tripod: The wall mount 25 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 laser tool can be moved vertically (when mounted to the wall) or horizontally (when mounted to a tripod) within a range of approx. 6 in. For this, loosen screw 27 on the alignment unit, move the laser tool to the desired position, and retighten screw 27 again.
Working with the Ceiling Measurement Plate (see figure A)
As an example, the ceiling measurement plate 29 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 unfavorable conditions; the laser beam can also be seen from the rear side through the transparent half.
Working with the Measuring Rod (Accessory) (see figure F)
WARNING Do not operate during storms or near high voltage. Risk of being struck by lightning or electrocution.
Keep at a safe distance from electrical installations. It is essential to work in this environment, first contact the safety authorities responsible for the electrical installations and follow their instructions.
For checking irregularities or projecting gradients, it is recommended to use the measuring rod 22 together with the laser receiver.

Assembly
Inserting/Replacing the Battery
Using alkaline batteries is recommended for operation of the remote control. To open the battery lid 12a, pull on the latch 13a 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 compartment.
The batteries must be replaced when operation indicator 2a no longer lights up after pressing any button on the remote control.
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
Initial Operation
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 batteries with sufficient voltage are inserted.
Set up the rotational laser in such a manner that the signals of the remote control directly reach one of the reception lenses on the rotational laser (for this, see the operating instructions of the rotational laser). 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 2a indicates that a signal was sent out. Switching the rotational laser on/off with the remote control is not possible.
Operating Modes
Function of buttons that are both on the rotational laser level as well as on the remote control do not differ. With exception of the hibernation mode, no additional functions of the rotational laser level can be controlled with the remote control. Example: Pressing the rotation operation button switches the rotational laser level from line operation to rotation operation. This happens no matter if you press the rotation operation button on the rotational laser level or on the remote control. When the rotational laser level does not have different rotational speeds, then the rotational speed can also not be changed with the remote control.
The ADS function cannot be controlled with the remote control. For detailed information of the rotational laser functions, see the operating instructions of the rotational laser.
Hibernation Mode
The rotational laser level can be switched to hibernation mode. For this, press the hibernation mode button 1a on the remote control. Rotation laser level is switched off, and the set operating mode is saved. Hibernation mode can only be started with the remote control.
Press any button on the remote control or keypad to restart the rotational laser level in the saved operating mode.
Rotation, Line and Point Operation
By pressing the rotation operation button 9a, you can switch from line to rotation operation and change between 3 different speed and spot mode settings. By pressing the line operation button 3a, you can switch from rotation to line operation or increase the aperture angle in steps.
Rotating the Laser Point/Laser Line in the Rotational Plane
The laser point or the laser line can be rotated in steps by 360^ within the rotational plane. Press button 5a to rotate in clockwise direction, and button 7a to rotate in counter clockwise direction.
Pressing and holding the buttons increases the speed of the rotation head in the desired direction. Rotating is (independent of the position of the rotational laser level) also possible in slope operation.
Manual Operation and Manual Slope from the Remote Control
To switch off the automatic leveling, press the slope operation button on the remote control once. The X leveling indicator LED will start flashing red (if the unit was already set to manual mode in the Y axis only, then the Y leveling indicator LED will start flashing red), then press the X lower/upper direction button or the Y lower/upper button to adjust the respective axis. The setting will be locked down after 5 seconds and the leveling indicator LED will stop flashing. The axis is no longer adjustable. If the slope operation button 10a has been pressed, but no adjustment button has been pressed within 5 seconds the unit will return to the previously set mode.
To reset both axes to automatic leveling press the slope operation button again while the respective leveling indicator LED is flashing. The X and/or Y leveling indicator LED will start flashing green (leveling still in process) or light up green.
Maintenance and Service
Keep the remote control clean at all times.
Do not immerse the remote control into water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or solvents.
If the 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 remote control yourself.
