laser line at the door opening and allow the measuring
tool to level in.
– Mark the centre of the vertical laser line on the floor of the
door opening (point Ⅰ), 5 m away on the other side of the
door opening (point Ⅱ) and on the upper edge of the door
opening (point Ⅲ).
– 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 × 0.5 mm/m
Example: At a door opening height of 2 m, the maximum de-
viation amounts to
2 × 2 m × ±0.5 mm/m = ±2 mm. The points Ⅲ and Ⅳ must
therefore be no further than 2 mm from each other.

Repeat the measuring procedure for the lateral vertical laser
line. To do this, turn the measuring tool through 90° before
beginning the measurement.

Working Advice

Only the centre of the laser line must be used for
u
marking. The width of the laser line changes depending
on the distance.
Working with the Laser Target Plate
The laser target plate (12) improves visibility of the laser
beam in unfavourable conditions and at greater distances.
The reflective surface of the laser target plate (12) 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)
A tripod offers a stable, height-adjustable support surface
for measuring. Place the measuring tool with the 1/4" tripod
mount (5) on the thread of the tripod (14) or a conventional
camera tripod. Tighten the measuring tool using the locking
screw of the tripod.
Roughly align the tripod before switching on the measuring
tool.
Securing with the universal holder (accessory)
Using the universal holder (11), you can secure the measur-
ing tool on vertical surfaces, pipes or magnetizable materi-
als, for example. The universal holder is also suitable for use
as a floor stand and facilitates height adjustment of the
measuring tool.
Roughly align the universal holder (11) 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.

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
bag provided.
If the measuring tool needs to be repaired, send it off in the
protective bag.
