To
switch off
the measuring tool, press the On/Off button
3
until
the automatic levelling indicator
2
goes out. Push the switch for
automatic levelling
4
to the position to lock the levelling unit.
f
Do not leave the switched on measuring tool unattended
and switch the measuring tool off after use.
Other per-
sons could be blinded by the laser beam.
When not using the measuring tool, switch it off in order to ex-
tend the battery life.
Operating Modes
The measuring tool has three operating modes, in which up to
three laser beams are generated: In cross-line operation, a laser
cross is indicated towards the front as well as a vertical laser line
at a 90° angle; in both other operating modes, both the horizon-
tal as well as the vertical line of the laser cross are indicated in-
dividually.
After switching on, the measuring tool is in cross-line operating
mode. To change the operating mode, press the On/Off but-
ton/operating mode button
3
as often as required until the re-
quested operating mode is set.
All operating modes can be selected both with and without au-
tomatic levelling.
Application
The measuring tool is used for determining and checking hori-
zontal and vertical lines as well as for indicating inclines. With
the two vertical laser lines that run at a 90° angle, right angles
can be indicated and checked, e.g., when dividing up spaces.
Working with Automatic Levelling (see figures A – E)
Position the measuring tool on a level and firm support or mount
it to the tripod
10
.
For work with automatic levelling, push the switch for automatic
levelling
4
to the
position. The automatic levelling indicator
2
lights up green (
symbol/
“green”
).
If automatic levelling is not possible, e.g. because the surface
on which the measuring tool is standing deviates by more than
4° from the horizontal plane, the automatic levelling indicator
2
lights up red, the laser lines flash and an audio signal sounds.
f
Do not hold the measuring tool close to your ear!
The loud
audio signal can cause hearing defects.
In this case, bring the measuring tool to the level position and
wait for the self-levelling to take place. As soon as the measuring
tool is within the self-levelling range of
±
4° again, the laser lines
light up continuously, the automatic levelling indicator
2
lights
up green and the audio signal is switched off.
When not within the self-levelling range of
±
4°, working with
automatic levelling is not possible, because it cannot be as-
sured that the laser lines run at a right angle to each other.
In case of ground vibrations or position changes during opera-
tion, the measuring tool is automatically levelled in again. To
avoid errors, check the position of the horizontal and vertical la-
ser line with regard to the reference points upon re-levelling.
Working without Automatic Levelling (see figure F)
For work without automatic levelling, push the switch for auto-
matic levelling
4
to the position. The automatic levelling indi-
cator
2
lights up red ( symbol/
“red”
).
When automatic levelling is switched off, you can hold the
measuring tool freely in your hand or place it on an inclinded
surface. The laser lines no longer necessarily run vertical to
each other.
Working Advice
f
Always use the centre of the laser line for marking.
The
width of the laser line changes with the distance.
Working with the Tripod
A tripod
10
offers a stable, height-adjustable measuring sup-
port. Place the measuring tool via the tripod mount
5
onto the
1/4" male thread of the tripod and screw the locking screw of
the tripod tight.
Laser Viewing Glasses
The laser viewing glasses filter out the ambient light. This makes
the red light of the laser appear brighter for the eyes.
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 radi-
ation.
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.
Maintenance and Service
Maintenance and Cleaning
Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any
cleaning agents or solvents.
Regularly clean the surfaces at the exit opening of the laser in
particular, and pay attention to any fluff of fibres.
If the measuring tool should fail despite the care taken in manu-
facturing and testing procedures, repair should be carried out
by an authorised after-sales service centre for Bosch power
tools. Do not open the measuring tool yourself.
In all correspondence and spare parts orders, please always in-
clude the 10-digit article number given on the type plate of the
measuring tool.
Symbol
Operating Mode
Cross-line operation
(see figures A–C
and F)
:
The measuring tool generates a hori-
zontal and a vertical laser line out of the front
laser beam exit opening as well as a vertical
laser line out of laser beam exit opening
1
on
the side. Both vertical laser lines run at a 90°
angle to each other.
Horizontal operation
(see figure D): The
measuring tool generates a horizontal laser
line out of the front laser beam exit opening
1
.
Vertical operation
(see figure E): The
measuring tool generates a vertical laser line
out of the front laser beam exit opening
