Align the laser beam so that it runs as parallel
as possible to the plumb line. Tilt the laser
beam in the ◀ direction by pressing the ▲
button (4). Tilt the laser beam in the ▶ direc-
tion by pressing the ▼ button (3).
If it is not possible to align the laser beam in parallel to the
plumb line, align the measuring tool to the wall more pre-
cisely and start the calibration process again.
If the laser beam is aligned in parallel, save the calibration
with by pressing the slope button (14).
This symbol confirms that the Z-axis has
been calibrated successfully. At the same
time, the status indicator (12) will flash
green three times. End the calibration with
by pressing the slope button (14).
If the calibration has been completed successfully, the
measuring tool then automatically switches itself off.
This error message will appear if calibration
of the Z-axis has been unsuccessful. Cancel
the calibration with
ton for line operation (5).
Ensure that the reference vertical line is in the pivoting range
of the rotation head and restart the calibration. Make sure
that the measuring tool is not moved during calibration.
If calibration fails again, have the measuring tool checked by
a Bosch customer service agent.

Working Advice

Only the centre of the laser point or laser line must be
u
used for marking. The size of the laser point/the width of
the laser line changes depending on the distance.
The measuring tool is equipped with a wireless inter-
u
face. Local operating restrictions, e.g. in aeroplanes
or hospitals, must be observed.

Working with the Laser Target Plate

The laser target plate (53) improves visibility of the laser
beam in unfavourable conditions and at greater distances.
The reflective half of the laser target plate (53) improves vis-
ibility of the laser line. The transparent half enables the laser
line to be seen from behind the laser target plate.
Bosch Power Tools

Working with the Tripod (Accessory)

A tripod offers a stable, height-adjustable support surface
for measuring. For horizontal operation, place the measuring
tool with the 5/8" tripod mount (18) on the thread of the tri-
pod (44). Tighten the measuring tool using the locking screw
of the tripod.
For vertical operation, use the 5/8" tripod mount (20).
On a tripod featuring a measuring scale on its extender, you
can set the height deviation straight away.
Roughly align the tripod before switching on the measuring
tool.

Laser Goggles (Accessory)

The laser goggles filter out ambient light. This makes the
light of the laser appear brighter to the eye.
Do not use the laser goggles as protective goggles.
u
The laser goggles make the laser beam easier to see; they
do not protect you against laser radiation.
Do not use the laser goggles as sunglasses or while
u
driving. The laser goggles do not provide full UV protec-
tion and impair your ability to see colours.
Working with a wall mount and alignment unit
(see figure D)
The measuring tool can be secured to the wall using the wall
mount with the alignment unit (45). Using the wall mount is
recommended, e.g. when working above the maximum ex-
tension height of tripods, or when working on unstable sur-
faces without a tripod.
Fasten the wall mount (45) either to a wall using screws
through the fixing holes (47) or to a strip of wall using the
fastening screw. (46) Fit the wall mount as perpendicular as
possible to the wall and ensure it is mounted in a stable way.
Screw the 5/8" wall mount screw (50) into the horizontal tri-
by pressing the but-
pod mount (18), depending on the requirements of the task,
or the vertical tripod mount (20) on the measuring tool.
Using the alignment unit allows the measuring tool to be
moved in a range of approx. 13 cm with respect to height.
Press the button (48) and move the alignment unit to
roughly the required height. It is possible to align the laser
beam precisely to a reference height using the fine adjust-
ment screw (49).
Working with the measuring rod (accessory)
(see figure E)
To check levels or apply slopes, it is recommended to use
the measuring rod (43) together with the laser receiver.
A relative measuring scale is incorporated at the top of the
measuring rod (43). You can preselect its zero at the bottom
on the extender. This enables you to read deviations from
the target height straight away.

Example applications

Projecting/checking heights (see figure F)
Position the measuring tool in the horizontal position on a
firm support or mount it on a tripod (44) (accessory).
Working with a tripod: Set the laser beam at the required
height. Project or check the height at the target location.
