Assembly

Power Supply of the Rotational Laser Level
Operation with Batteries/Rechargeable Batteries Using alkali-manganese or rechargeable batteries is recommended for operation of the measuring tool.

• To open the battery compartment 14, turn the locking knob 15 to position and pull out the battery compartment.
  When inserting the batteries/rechargeable batteries, pay at-tention to the correct polarity according to the representation on the inside of the battery compartment.
  Always replace all batteries/rechargeable batteries at the same time. Do not use different brands or types of batter-ies/rechargeable batteries together.

• Shut the battery compartment 14 and turn the locking knob 15 to the position.
  In case the batteries/rechargeable batteries have been inserted incorrectly, the measuring tool cannot be switched on. Insert the batteries/rechargeable batteries with correct polarity.

• Remove the batteries/rechargeable batteries from the measuring tool when not using it for longer periods. When storing for longer periods, the batteries/rechargeable batteries can corrode and self-discharge.

Operation with Battery Pack

• Charge the battery pack 13 before using for the first time. The battery pack can only be charged with the battery charger 22 intended for it.
  Observe the mains voltage! The voltage of the power source must correspond with the data on the type plate of the battery charger.

• Insert the appropriate mains plug 23 for your mains supply into the battery charger 22 and allow it to engage.

• Insert the charge plug 24 of the battery charger into the socket connector 17 of the battery pack. Connect the bat-tery charger to the mains supply. Charging the empty bat-tery pack takes approx. 14 h. The battery charger and the battery pack are protected against overcharging.

A battery that is new or has not been used for a longer period does not develop its full capacity until after approx. 5 charg-ing/discharging cycles.
Do not charge the battery pack 13 each time after using, oth-erwise its capacity will be reduced. Charge the battery pack only when the charge-control indicator 12 flashes or lights up continuously.
A considerably reduced operating period after charging indi-cates that the battery pack is used up and must be replaced.
If the battery pack is empty, the measuring tool can also be operated off of the battery charger 22 when connected to a power supply. Switch the measuring tool off, charge the battery pack for approx. 10 min and then switch the measuring tool on again with the battery charger connected.

• To change the battery pack 13, turn the locking knob 16 to position and pull out the battery pack 13.
• Insert a new battery pack and turn the locking knob 16 to the position.

Remove the battery pack from the measuring tool when not using it for longer periods. When storing for longer periods, the rechargeable batteries can corrode and self-discharge.

Charge-control Indicator
When the charge-control indicator 12 flashes red for the first time, the measuring tool can still be operated for approx. 2 h.
When the charge-control indicator 12 lights up red continu-ously, measurements are no longer possible. The measuring tool switches off automatically after 1 minute.

Power Supply of the Remote Control
Using alkali-manganese batteries is recommended for operation of the remote control.

• To open the battery lid 34, press the latch 33 in the direction of the arrow and remove the battery lid. Insert the battery provided. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment.
• Remove the battery from the remote control when not using it for longer periods. When storing for longer peri-ods, the battery can corrode and discharge itself.

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 25) 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

• Set up the measuring tool on a sturdy surface in the horizontal or vertical position; mount it on a tripod 37 or to the wall mount with alignment unit 39.

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 re-levelling.

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 24). In this case, the measuring tool starts in the set operating mode up-on completion of levelling in.

• 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 25). 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 ad-just 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 30 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 ex-ample, 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 rotation-al operation mode with average rotational speed.

• To switch from line operation to rotational operation, press the rotational operation button 5 or button 25 on the re-mote control. Rotational operation starts with average rotational speed.
  To change the rotational speed, press the rotational operation button 5 or button 25 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, re-duce the rotational speed for improved visibility of the laser beam and use the laser viewing glasses 38.

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

• To switch to line or point operation, press the line operation button 11 or button 26 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 but-ton 11 or button 26 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 28 to rotate in clockwise direction, and button 29 on the remote control to rotate in anticlockwise direction. In rotational operation, pressing the buttons has no effect.
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 28 on the remote control to rotate in clockwise direction, and button 29 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 uneven-ness 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 relevel. Without re-positioning, 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.

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 shock- warning button 2 on the measuring tool or the shock-warning reset button 27 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.

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 27 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 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.

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 up-ward 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 center of the work area.

Accuracy Check of the Measuring Tool
Apart from exterior influences, device-specific influences (such as heavy impact or falling down) can lead to deviations. Therefore, check the accuracy of the measuring tool each time before starting your 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 37 (accessory) or place it on a firm and level surface near wall A. Switch the measuring tool on.

• After levelling, direct the laser beam in point operation on to the close wall A. Mark the center point of the laser beam on the wall (point I).

• Turn the measuring tool around by 180°, allow it to level in and mark the center point of the laser beam on the opposite wall B (point II).

• Without turning the measuring tool, position it close to wall B. Switch the measuring tool on and allow it to level in.

• Align the height of the measuring tool (using the tripod or by underlaying, if required) in such a manner that the center point of the laser beam is projected exactly against 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 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°.

The maximum permitted deviation over the measuring section of 2 x 20 m = 40 m is as follows:
40mx±0.1mm/m=±4mm.
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 center 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 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.

Working with the Laser Receiver (Accessory)
Under unfavorable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser beam 35.
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
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 18 onto the 5/8″ male thread of the tripod and screw the locking screw of the tripod tight.

On a tripod 37 with a measuring scale on the elevator column, the height difference can be adjusted directly.

Working with Wall Mount/Alignment Unit (Accessory) (see figure B)
You can also mount the measuring tool to the wall mount with alignment unit 39. For this, screw the 5/8″ screw 42 of the wall mount into the tripod mount 18 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 39, with the measuring tool mounted, as vertical as possible to a wall.
For mounting to the wall, you can either fasten the wall mount 39 with fastening screw 40 to a lath (width maximal 8 mm) or hang it up with two hooks.

Mounting on a tripod: The wall mount 39 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 41 on the alignment unit, move the measuring tool to the desired position, and retighten screw 41 again.

Working with the Ceiling Measurement Plate (see figure B)
As an example, the ceiling measurement plate 44 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 Laser Target Plate (Accessory) (see figure C)
With the laser target plate 43, 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 43 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.

Working with the Measuring Rod (Accessory) (see figure J)
For checking irregularities or projecting gradients, it is recommended to use the measuring rod 36 together with the laser receiver.

A relative millimeter scale (±50 cm) is marked on the top of the measuring rod 36. Its zero height can be preset at the bot-tom 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 37 (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 43. 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 43. 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 sup-posed 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 28 (clockwise rotation) or but-ton 29 on the remote control (anticlockwise rotation).

Working without Laser Receiver (see figure G)
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 rotate the rotation head 10 to the target location.

Working with the Laser Receiver (see figure H)
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.

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 center of the work surface and on a tripod.

Working Outdoors (see figure J)
The laser receiver should always be used when working out-doors.

• When working on unstable ground, mount the measuring  tool onto the tripod 37. Activate the shock-warning function in order to avoid faulty measurements in case of ground vibrations or shock to the measuring tool.
