When the charge-control indicator 12 lights up red continuously, leveling is no longer possible. The laser tool switches off automatically after 1 minute.

Operation

Initial Operation

WARNING

Protect the laser tool against moisture and

direct sun irradiation.

Do not subject the laser tool 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 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 tool can be impaired.

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 subject to extreme temperatures and temperature variations.

Avoid heavy impact and prevent the laser tool from falling. After heavy exterior impact on the laser tool, an accuracy check should always be carried out before continuing to work (see "Leveling Accuracy").

WARNING

If cage breaks when dropped, broken cage can

cause laceration hazard.

Setting Up the Laser Tool

Horizontal Position Vertical Position

Set up the laser tool on a sturdy surface in the horizontal or vertical position; mount it on a tripod 21 or to the wall mount with alignment unit 25.

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

Turning on the Laser Tool

△WARNING

DO NOT direct the laser beam at persons or not stare into the laser not even from a large

Do not leave the switched on laser tool unattended and switch the laser tool off after use. Serious eye injury could result from the laser beam.

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

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

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

With the operating mode buttons 5 and 11, the operating modes can already be specified during leveling in (see "Operating Modes, page 14). In this case, the laser tool starts in the set operating mode upon completion of leveling in.

Turning off the Laser Tool

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

• Do not leave the switched on laser tool unattended and switch the laser tool off after use.

To save the batteries, the laser tool is automatically switched off when not within the self-leveling range for more than 2h or when the shock warning is actuated for more than 2h (see "Automatic Leveling"). Reposition the laser tool and switch it on again.

Working Advice

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

Operating Modes

Overview

All three operating modes are possible with the laser 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.

Rotation Mode (150/300/600 min -1)

Each time after switching on, the laser tool is in rotational operation mode at default rotational speed (300 min -1).

To switch from line operation to rotational operation, press the rotational operation button 5.

Rotational operation starts at default rotational speed (300 min -1).

To change the rotational speed, press the rotational operation button 5 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.

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

To switch to line or point operation, press the line operation button 11. The laser tool switches to line operation with the smallest aperture angle.

To change the aperture angle, press the line operation button 11. 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 11 a third time, the laser tool switches to point operation after brief post-pulsation. Pressing button 11 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.

To position the laser line or the laser point within the rotational plane, manually turn the rotation head 10 to the requested position or use the remote control 20.

Turning the Rotational Plane when in the Vertical Position

When the laser tool is in the vertical position, it is possible to rotate the laser point, laser line or rotational plane around the vertical axis with help of the remote control 20. For this, follow the operating instructions of the remote control.

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% (5^)

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 flashes and leveling indicator 3 continuously lights up red. Reposition the laser tool and wait for it to re-level. Without repositioning, the laser is automatically switched off after 2 minutes and the laser tool after 2 hours.

When the laser tool is leveled in, it continuously checks the horizontal and vertical position. Automatic re-leveling takes place after position changes. To avoid faulty measurements, the rotor stops during the leveling process, the laser flashes and the leveling indicator 3 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 keeps the laser tool from leveling in at changed heights, and thus prevents errors.

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

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

After the shock-warning function is actuated, press the shock-warning button 2. The shock-warning function is restarted and the laser tool starts leveling. As soon as the laser tool is leveled in (leveling indicator 3 continuously lights up green), it starts in the stored operating mode. Now, check the position of the laser beam with a reference point and adjust it, if required.

If operation is not restarted by pressing button 2 after the shock warning function has actuated, the laser is automatically switched off after 2 minutes and the laser tool after 2 hours.

To switch off the shock-warning function, press shock-warning 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 shock warning indicator 1 goes out.

Accuracy Check

Influences on Accuracy

The ambient temperature has the greatest influence. 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 (30m) 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).

• 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.

• 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 (30m) is as follows:

For GRL800-20HV:

$$ 1 0 0 \mathrm {f t} \times \pm 3 / 1 6 \text {i n} = \pm 3 / 1 6 \text {i n} $$

$$ (3 0 \mathrm {m} \times \pm 0. 1 5 \mathrm {m m} = \pm 4. 5 \mathrm {m m}) $$

For GRL900-20HV and GRL1000-20HV:

$$ 1 0 0 f t x \pm 1 / 8 i n = \pm 1 / 8 i n $$

$$ (3 0 \mathrm {m} \times \pm 0. 1 0 \mathrm {m m} = \pm 3. 0 \mathrm {m m}) $$

The difference d between points I and II must therefore be maximum 3/8 in (9mm) for GRL800-20HV and 14 in (6 mm) for GRL900-20HV and GRL1000-20HV 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.

The maximum permitted deviation over a 30 ft (10 m) distance is as follows:

For GRL800-20HV:

$$ \begin{array}{l} 3 0 \mathrm {f t} \times \pm 3 / 1 6 \text {i n} = \pm 1 / 1 6 \text {i n} \ (1 0 \mathrm {m} \times \pm 0. 1 5 \mathrm {m m} = \pm 1. 5 \mathrm {m m}) \ \end{array} $$

For GRL900-20HV and GRL1000-20HV:

$$ \begin{array}{l} 3 0 f t x \pm 1 / 8 i n = \pm 3 / 6 4 i n \ (1 0 \mathrm {m} \times \pm 0. 1 \mathrm {m m} = \pm 1 \mathrm {m m}) \ \end{array} $$

The difference d must therefore be a maximum of 1/16 in (1.5 mm) for GRL800-20HV and 3/64 in (1 mm) for GRL900-20HV and GRL1000-20HV.

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 9 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, either select line operation, or select point operation and manually (or by using the remote control 20) rotate the rotation head 10 to the target location.

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.

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 and 13 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 is avoided when using the remote control 20.

Reception lenses 7 for the remote control are located on three sides of the laser tool (GRL800-20HV has a single reception lens located on the front of the laser tool), among other locations above the control panel on the front side.

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 8mm ) or hang it up with two hooks.

Mounting on a tripod: The wall mount 25 (WM4 only) 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.

RC1 Operation

Initial Operation

• Protect the remote control 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 laser tool in such a manner that the signals of the remote control directly reach one of the reception lenses on the laser tool (for this, see the operating instructions of the laser tool). 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 6c indicates that a signal was sent out.

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

RC1 Operating Modes

For detailed information of the laser tool functions, see the operating instructions of the laser tool.

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

The function of the button for rotational operation 1c on the remote control is identical with that on the laser tool.

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

To switch from line operation to rotational operation, press the rotational operation button 1c. Rotational operation starts with average rotational speed.

To change the rotational speed, press the rotational operation button 1c again until the requested speed is reached.

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

The function of the button for line operation 2c on the remote control is identical with that on the laser tool.

To switch to line or point operation, press the line operation button 2c. The laser tool switches to line operation with the smallest aperture angle.

To change the aperture angle, press the line operation button 2c. 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 2c a third time, the laser tool switches to point operation after brief post-pulsation. Pressing button 2c 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 K)

Rotating the laser line/laser dot or the rotational plane is possible only with the remote control.

When the laser 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.

Press button 4c to rotate in clockwise direction, and button 5c to rotate in counterclockwise direction. In rotational operation, pressing the buttons has no effect.

When the rotational laser 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-leveling range 5^ toward the left or right).

Press button 4c to rotate in clockwise direction, and button 5c to rotate in counterclockwise direction.

Reset Shock-warning Function

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

Switching the shock-warning function on and off is possible only on the laser tool. Once the shock-warning function has actuated, is can be restarted via the remote control.

After actuation of the shock warning function, the rotation of the laser is stopped, the laser flashes, the leveling indicator goes out, and the shock warning indicator flashes red. The current operating mode is stored.

After the shock-warning function has actuated, press the shock warning reset button 3c. The shock-warning function is restarted and the rotational laser starts leveling. As soon as the laser tool is levelled in (the leveling indicator on the laser tool 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.

RC1 Applications

Application Example Turning the Rotational Plane when in the Vertical Position (see figure L)

To align the vertical laser line or the rotational plane against a reference point on a wall,

set up the laser 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 4c (clockwise rotation) or 5c (counterclockwise rotation).

RC1 Maintenance

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 authorized customer services agent for Bosch power tools. Do not open the remote control yourself.
