Working Advice
f Always use the centre of the laser line for
marking. The width of the laser line changes
with the distance.
Working with the Alignment Plate
With the alignment plate 12, the measuring tool
can be aligned by a reference line or the vertical
laser line can be indicated at an angle of 45° or
90° to a reference line.
Position the measuring tool via the tripod mount
6 onto the pin 16 of the alignment plate. Posi-
tion it in such a manner on the alignment plate
that the vertical laser line (depending on the re-
quested angle) runs centrally through the align-
ment aid 13, 14 or 15.
Align the alignment plate 12 with the corre-
sponding alignment aids 13, 14 or 15 to the
desired reference line.
Working with the Measuring Plate (Accessory)
(see figures E–F)
With the measuring plate 20, 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 required height can be measured
and projected at another location. This elimi-
nates the necessity of precisely adjusting the
measuring tool to the height to be projected.
The measuring plate 20 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.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable meas-
uring support. Place the measuring tool via the
tripod mount 6 onto the 1/4" male thread of the
tripod and screw the locking screw of the tripod
tight.
Working with the Laser Receiver (Accessory)
(see figure G)
Under unfavourable light conditions (bright
environment, direct sunlight) and for larger
distances, use the laser receiver for improved
finding of the laser lines 21. When working with
the laser receiver, switch the pulse function on
(see “Pulse Function”, page 19).
Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambient
light. This makes the red light of the laser ap-
pear brighter for the eyes.
f
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.
f Do not use the laser viewing glasses as sun
glasses or in traffic. The laser viewing glass-
es do not afford complete UV protection and
reduce colour perception.
Work Examples (see figures H–K)
Laying Flooring Plates at a 45° Angle
(see figure J)
Position the measuring tool via the tripod mount
6 onto the pin 16 of the alignment plate. Posi-
tion it in such a manner on the centred protru-
sion of the alignment plate 12 that the vertical
laser line runs centrally through the alignment
aid 15. Then, align the alignment plate with the
alignment aids 13 or 14 with regard to the refer-
ence line.
For cross line or in vertical operation, the verti-
cal laser line on the floor indicates a 45° angle
to the reference line. Align the flooring plates
with regard to this line.
