Not all the accessories illustrated or described are included in standard de-
livery.
Working safely with this machine is possible only
when the operating and safety information are read
completely and the instructions contained therein
are strictly followed.
Laser radiation of laser class 2
630–675 nm, < 1.0 mW
according to EN 60825-1:1997
Do not look into the laser beam.
Do not point the laser beam at persons or animals.
Because of the narrow concentration of the laser beam,
care will be needed when tracking the beam for long dis-
tances.

For Your Safety

■The laser viewing glasses (accessory) are not protective glasses
against laser radiation. Do not use them as protective glasses against
strong sun light or in traffic.
■Children may only use the machine under the supervision of adults.
■Do not remove the warning sign from the unit.
■Have repairs carried out only by a Bosch After-Sales Service. Never
open the unit yourself.
■Bosch is only able to ensure perfect functioning of the machine if the
original accessories intended for it are used.
■Avoid heavy shocks or falls. After heavy exterior influences on the unit,
always perform a precision check before continuing work (see Section
Levelling Accuracy).
■The unit can be used in indoor and outdoor areas. It is protected
against splash water but not 100 % waterproof; do not immerse the
unit in water.
■Do not expose the unit to extreme temperatures and temperature var-
iations (e. g., do not leave in vehicles).
Loosen the screw of the battery compartment cover 14. Remove the bat-
tery compartment cover 13. Insert the batteries into the housing such that
the negative terminals rest against the battery springs. Mount the cover
and tighten the screw.
The 1.5 V mono-cells (LR 20) provided make possible an operating time
of approx. 40 hours in rotation mode.
Extreme temperatures and the use of batteries of different charged con-
ditions decrease the operational duration of the unit.
■Always replace both batteries. Never use batteries of different capac-
ity. Use batteries from only one manufacturer, if possible.
■Do not look directly into the laser beam and do not point the laser
beam at the eyes of other persons. When the construction laser is
switched on, the laser is activated. The laser emits beams upwards
and to the side.
Switching On/Off: Press the on-off switch 5.
☞When the maximum allowed operating temperature of 45 °C is
exceeded, the laser beam automatically switches off in order
to protect the laser diode. After cooling, the unit is again ready
for operation and can be switched on again.
Horizontal Alignment/Aligning the Plumb Beam
Switch on the construction laser and align with the bubble level (1) 6by
turning the adjustment knob (1) 8to the right until level. The bubble level
(3) 12 is aligned by turning the adjustment knob (2) 10 to the right. When
the bubble levels 6and 12 are aligned, the unit is level and ready for op-
eration.

Vertical Alignment
Switch on the construction laser and, as shown in the illustration, align the
bubble level (2) 7by rotating the adjustment knob (2) 10 up or down until
level.
Note: When working over an extended period of time, check the position
of the level bubbles regularly.
Influences on the Accuracy
☞The largest influence is exerted by the ambient temperature.
Especially temperature differences occurring from the ground
upwards can deflect the laser beam.
The deviations are significant at a distance of approx. 20 m and can
double or quadruple at a distance of 100 m.
Since the temperature gradient near the floor is the greatest, a tripod
should always be used when working at distances over 20 m. In addi-
tion, the unit should always be set up in the middle of the working area.
Accuracy Check of the Unit
In addition to external influences, deviations can also be caused by influ-
ences within the unit itself. For this reason, the accuracy should be
checked from time to time.
Procedure
– A free measuring path of 20 m is required.
– A transit measurement on firm ground must be performed over both
X and Y axes (four measurements).
– Place the unit in the horizontal position on a solid, level base and
switch on.
– After levelling, mark the laser point (centre of the point) at a convenient
position, for example, on a wall.
– Then rotate the unit by approx. 90° without lifting it, i.e., without
changing its height.
– Now turn back the prism cap 1, realign with the bubble levels and
mark again. Repeat this procedure in two additional 90° steps. The
heights of all four measurements are now marked at the same posi-
tion on the wall.
The maximum deviation at 20 m must not exceed ±6 mm. Consequently,
the highest and lowest markings can be 12 mm apart. This deviation re-
sults from tolerances of the unit and application when checking the accu-
racy.
Should the unit be outside of these tolerances, please contact a Bosch
Service Centre.

Rotation operation
To select rotation operation, slide down the ring for the line function 3and
press the mode selector switch 4. The laser starts with the highest rota-
tional speed. The rotational speed is adjustable in order to enhance the
visibility of the laser beam. Repeated pressing of the mode selector switch
4reduces the speed in 3 steps to a standstill.
When working with the receiver 17, the highest rotational speed is recom-
mended.
When working without the receiver 17, the lowest rotational speed or line
operation is recommended.
Point operation
After switching on, the unit emits a laser beam which is split into two
beams at a right-angle at the laser exit.
In the horizontal position, this results in a continuous vertical plumb
beam and a variable horizontal beam which is deflected by 90°.
In the vertical position, a continuous plane beam and a variable vertical
beam are available.
By simply turning the prism cap 1, the variable beam is directed manually
to the desired position.
Point operation is particularly well suited for interior work.
Standard Line
To select line operation, slide up the ring for line function 3and press the
mode selector switch 4. The laser starts with the longest line length which
is adjustable depending on the visibility and working area. Repeated
pressing of the mode selector switch 4reduces the length L of the line in
3 steps to a standstill.
By simply turning the prism cap 1, the line can be moved manually.
☞Set the desired line length before measuring.
Do not point the laser beam at persons or animals.
Working with a Tripod (Accessory)
The construction laser is equipped with 1/4" tripod receptacles 16 for
horizontal and vertical applications. To mount the construction laser on a
tripod 22 with 5/8" threads, use the adapter 23 provided.
For tripods 22 with a millimetre scale on the extension, the height offset
can be set directly.
Operation with Wall Mount
For work exceeding the extension height of tripods, the
unit can be operated with the wall mount 24. Attach the
wall mount 24 to the wall.
The construction laser is inserted into the wall mount
from above and secured with the locking lever.
