Safety Notes
Rotational Laser Level
Working safely with the measuring tool is
possible only when the operating and safety
information are read completely and the instructions contained therein are strictly followed. Never make warning labels on the
measuring tool unrecognisable. SAVE
THESE INSTRUCTIONS.
f Caution – The use of other operating or adjusting
equipment or the application of other processing methods than those mentioned here, can lead to dangerous
radiation exposure.
f 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.
f 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.
f Have the measuring tool repaired only through qualified specialists using original spare parts. This ensures
that the safety of the measuring tool is maintained.
f Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids,
gases or dusts. Sparks can be created in the measuring
tool which may ignite the dust or fumes.
f Do not open the battery pack. Danger of short-circuiting.
Protect the battery pack against heat, e.g.,
against continuous intense sunlight, fire, water,
and moisture. Danger of explosion.
f Keep the battery pack not being used away from paper
clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
f Under abusive conditions, liquid may be ejected from
the battery pack; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritations or burns.

f Charge the battery pack only with the battery charger
specified in these operating instructions. A charger that
is suitable for one type of battery pack may create a risk of
fire when used with another battery pack.
f Use only original Bosch battery packs with the voltage
listed on the nameplate of your measuring tool. When
using other battery packs, e.g. imitations, reconditioned
battery packs or other brands, there is danger of injury as
well as property damage through exploding battery packs.
Keep the laser target plate 43 and the
ceiling measurement plate 44 away from
cardiac pacemakers. The magnets on the
laser target plate and on the ceiling measurement plate generate a field that can impair the function of cardiac pacemakers.
f Keep the laser target plate 43 and the ceiling measurement plate 44 away from magnetic data medium and
magnetically-sensitive equipment. The effect of the
magnets on the laser target plate and on the ceiling measurement plate can lead to irreversible data loss.

Operation
Starting Operation of the Rotational Laser Level
f Protect the measuring tool against moisture and direct
sun light.
f Do not subject the measuring 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 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.
f 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.
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 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 relevelling.
Switching On and Off
f 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 23). In this
case, the measuring tool starts in the set operating mode upon completion of levelling in.
To switch off the measuring tool, press the On/Off button 4
again.
Bosch Power Tools
f 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 24). Reposition the measuring tool and switch it on again.
Starting Operation of the Remote Control
f Protect the remote control against moisture and direct
sunlight.
f 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 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 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 25 on the remote
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, reduce 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 button
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
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 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.
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.

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
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.
A
B
20 m
– After levelling, direct the laser beam in point operation onto the close wall A. Mark the centre point of the laser beam
on the wall (point I).
A
B
180°
– Without turning the measuring tool, position it close to wall
B. Switch the measuring tool on and allow it to level in.
A
B
– 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
180°
B
– 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°.
On the measuring section of 2 x 20 m = 40 m, the maximum
allowable deviation is:
40 m x ±0.1 mm/m = ±4 mm.
Consequently, the difference d between points I and III for
each of the four individual measurements may not exceed
4 mm max.
If the measuring tool should exceed the maximum deviation in
anyone of the four measuring procedures, have it checked at
a Bosch after-sales service agent.
Working Advice
f Always use the centre of the laser point for marking.
The size of the laser point changes with the distance.
– Turn the measuring tool around by 180°, allow it to level in
and mark the centre point of the laser beam on the opposite wall B (point II).
Bosch Power Tools
Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out ambient light. This enhances the laser visibility for the eye.
f 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.

OBJ_BUCH-757-007.book Page 26 Tuesday, June 21, 2011 10:16 AM
26 | English
f 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 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.
1 619 929 J21 | (21.6.11)
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 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 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 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.
plane with the reference point. For precise alignment with the
reference point, press button 28 (clockwise rotation) or button 29 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.
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.
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 37. Activate the shock-warning function in order to avoid faulty measurements in case of ground vibrations
or shock to the measuring tool.
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
