– Rotate the measuring tool 180° and position it on the
other side of the door opening, directly behind point Ⅱ.
Allow the measuring tool to level in and align the vertical
laser line in such a way that its centre passes through
points Ⅰ and Ⅱ exactly.
– Mark the centre of the laser line on the upper edge of the
door opening as point Ⅳ.
– The discrepancy d between the two marked points Ⅲ and
Ⅳ reveals the actual vertical deviation of the measuring
tool.
– Measure the height of the door opening.
You can calculate the maximum permitted deviation as fol-
lows:
Doubled height of the door opening × 0.2 mm/m
Example: At a door opening height of 2 m, the maximum de-
viation amounts to
2 × 2 m × ±0.2 mm/m = ±0.8 mm. The points Ⅲ and Ⅳ
must therefore be no further than 0.8 mm from each other.

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.
Working with the Laser Target Plate
The laser target plate (26) improves visibility of the laser
beam in unfavourable conditions and at greater distances.
The reflective surface of the laser target plate (26) improves
visibility of the laser line. The transparent surface enables
the laser line to be seen from behind the laser target plate.
Working with the Tripod (Accessory) (see figure F)
A tripod offers a stable, height-adjustable support surface
for measuring. Place the measuring tool on the rotating
platform (12) to assemble the measuring tool on a tripod.
Assembly on a 5/8" tripod: Place the rotating platform with
the 5/8" tripod mount (9) on the thread of a commercially
available 5/8" tripod (28) or a commercially available build-
ing tripod. Tighten the rotating platform using the locking
screw of the tripod.
Assembly on a 1/4" tripod (see figure F): Screw the tripod
adapter (20) (accessory) into the 5/8" tripod mount (9) of
the rotating platform. Place the tripod adapter with the 1/4"
tripod mount on the thread of a 1/4" tripod (21) or a com-
Bosch Power Tools
mercially available camera tripod. Tighten the tripod adapter
using the locking screw of the tripod.
Roughly align the tripod before switching on the measuring
tool.
Working with the laser receiver (accessory)
Use the laser receiver (22) to improve detection of the laser
lines in adverse lighting conditions (bright environment, dir-
ect sunlight) and over greater distances. When working with
the laser receiver, switch on receiver mode (see "Receiver
Mode", page 8).
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 (accessory) as protective
u
goggles. The laser goggles make the laser beam easier to
see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as
u
sunglasses or while driving. The laser goggles do not
provide full UV protection and impair your ability to see
colours.
Example applications (see figures B–E)
Examples of possible applications for the measuring tool can
be found on the graphics pages.

Maintenance and Service

Maintenance and Cleaning

Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a damp, soft cloth. Do not use any de-
tergents or solvents.
The areas around the outlet aperture of the laser in particular
should be cleaned on a regular basis. Make sure to check for
lint when doing this.
Only store and transport the measuring tool in the protective
pouch (27).
If the measuring tool needs to be repaired, send it off in the
protective pouch (27).
