Working without Automatic Levelling
If you switch off the automatic levelling system, you can hold
the measuring tool freely in your hand or set it down on a slop-
ing surface. This means that the two laser lines are no longer
necessarily running perpendicularly to one another.
To make sure that the two laser lines are still perpendicular to
one another, position the measuring tool at an angle of 90° to
the wall.
Working Advice
 Always use the centre of the laser line for marking. The
width of the laser line changes with the distance.
Working with the Tripod (see figure H)
A tripod 13 offers a stable, height-adjustable measuring sup-
port. Place the measuring tool via the tripod mount 8 onto the
1/4" male thread of the tripod and screw the locking screw of
the tripod tight.
Working with the Wall Mount (Accessory)
With the wall mount 14, the measuring tool can be securly at-
tached at any height.
Mounting the wall mount (see figure I): For fastening to a
wall, the holding plate 16 must be folded out. Press pushbut-
tons 15 on both sides of the holding plate (a), fold the holding
plate up (b), lightly push it downward and allow it to latch (c).
For height adjustment of the measuring tool, the holding plate
16 can be moved up or down within a range of 6 cm. For this,
press the pushbuttons 15 on both sides of the holding plate,
slide the holding plate to the requested height and allow it to
latch again. The scale on the side of the wall mount aids the
height adjustment.
Fastening the wall mount (see figure J): Fasten the wall
mount 14 as vertical as possible to a wall with the holding
plate 16 folded up. Secure it safely against slipping off, e.g.,
with two fastening screws 17 (commercially available).
Screw the 1/4" screw 18 of the wall mount into the tripod
mount 8 of the measuring tool.
Using as a table stand (see figure K): In the plumb beam op-
erating mode, the visibility of the bottom plumb beam 3 can be
improved by not placing the measuring tool directly on a sur-
face, but by inserting it in the folded together wall mount 14.
For this, place the wall mount as horizontal as possible onto a
firm and level support. Press pushbuttons 15 at the holding
plate 16 (a). Slide the holding plate to the stop against the up-
per end of the wall mount (b). Fold the holding plate down-
ward (c). Screw the 1/4" screw 18 of the wall mount into the
tripod mount 8 of the measuring tool. Then, allow the holding
plate to latch in the wall mount.
Turn the mounted measuring tool in such a manner that the
bottom plumb beam 3 faces downward. If required, lightly
fold up the holding plate again to loosen the 1/4" screw 18 for
alignment of the measuring tool.

Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambient light. This
makes the red light of the laser appear brighter for the eyes.
 Do not use the laser viewing glasses as safety goggles.
The laser viewing glasses are used for improved visualisa-
tion 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 colour perception.
Maintenance and Service
Maintenance and Cleaning
Store and transport the measuring tool only in the supplied

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

Regularly clean the surfaces at the exit opening of the laser in
particular, and pay attention to any fluff or fibres.
In case of repairs, send in the measuring tool packed in its
protective pouch 20.
