other side of the door opening (point II) and at the upper
edge of the door opening (point III).
– Rotate the measuring tool by 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 manner that its centre runs exactly
through points I and II.
– Mark the centre of the laser line at the upper edge of the
door opening as point IV.
– The difference d of both marked points III and IV results in
the actual deviation of the measuring tool to the plumb line.
– Measure the height of the door opening.
The maximum admissible deviation is calculated as follows:
Doubled height of the door opening x 0.5 mm/m
Example: For a door-opening height of 2 m, the maximum
deviation may be 2 x 2 m x ±0.5 mm/m = ±2 mm. Conse-
quently, points III and IV may be no more than 2 mm (max.)
apart from each other for each of both measurements.
Repeat the measuring procedure for the lateral vertical laser
line. For this, turn the measuring tool by 90° before beginning
with the measuring procedure.
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 Laser Target Plate (Accessory)
The laser target plate 11 increases the visibility of the laser
beam under unfavourable conditions and at large distances.
The reflective part of the laser target plate 11 improves the vis-
ibility of the laser line. Thanks to the transparent part, the laser
line is also visible from the back side of the laser target plate.
Working with the Tripod (Accessory)
A tripod 15 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.
Fastening with the Universal Holder (Accessory)
With the universal holder 13, you can fasten the measuring
tool, e.g., to vertical surfaces, pipes or magnetisable materi-
als. The universal holder is also suitable for use as a ground tri-
pod and makes the height adjustment of the measuring tool
easier.

Working with the Measuring Plate (Accessory)
(see figures G–H)
With the measuring plate 12, it is possible to project the laser
mark onto the floor or the laser height onto a wall.
With the zero field and the scale, the offset or drop to the re-
quired height can be measured and projected at another loca-
tion. This eliminates the necessity of precisely adjusting the
measuring tool to the height to be projected.
The measuring plate 12 has a reflective coating that enhances
the visibility of the laser beam at greater distances or in intense
sunlight. The brightness intensification can be seen only when
viewing, parallel to the laser beam, onto the measuring plate.
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
protective pouch.
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 or fibres.
