Working Advice

Working with the Tripod (see figure H)
A tripod 12 offers a stable, height-adjustable
measuring support. 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 13, the measuring tool can
be securly attached at any height.
Mounting the wall mount (see figure I): For fas-
tening to a wall, the holding plate 15 must be fold-
ed out. Press pushbuttons 14 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 15 can be moved up or down within
a range of 6 cm. For this, press the pushbuttons
14 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 13 as vertical as possible to a wall
with the holding plate 15 folded up. Secure it
safely against slipping off, e.g., with two fasten-
ing screws 16 (commercially available). Screw
the 1/4" screw 17 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 operating mode, the visibility of the
bottom plumb beam 3 can be improved by not
placing the measuring tool directly on a surface,
but by inserting it in the folded together wall
mount 13.
For this, place the wall mount as horizontal as
possible onto a firm and level support. Press
pushbuttons 14 at the holding plate 15 (a). Slide
the holding plate to the stop against the upper
end of the wall mount (b). Fold the holding plate
downward (c). Screw the 1/4" screw 17 of the
wall mount into the tripod mount 8 of the meas-
uring tool. Then, allow the holding plate to latch
in the wall mount.
Bosch Power Tools
Turn the mounted measuring tool in such a man-
ner that the bottom plumb beam 3 faces down-
ward. If required, lightly fold up the holding plate
again to loosen the 1/4" screw 17 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 visualisation 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.

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 manufacturing and testing procedures,
repair should be carried out by an authorized
after-sales service centre for Bosch power tools.
