Working Instructions

Working with the Measuring Plate
With the aid of the measuring plate 25, the laser beam
can be transferred to the floor or the laser height to the
wall.
With the zero field and the scale, the offset to the de-
sired height can be measured and marked at other lo-
cations. In this manner, the exact placement of the unit
at the height to be transferred is not necessary.
➨
Always use the middle of the laser point for mark-
ing since the size of the point changes with the
distance.
The measuring plate has a reflective coating for better
visibility of the laser beam at longer distances or in
strong sunlight.
The brightness intensification can be detected only
from the unit, therefore sight with the eye along the la-
ser beam to the measured location (measuring plate).
Measuring Rod (accessory)
For outdoor work such as for checking surface even-
ness or marking inclines, it is recommended to use the
measuring rod 22 together with the receiver 28.
On the measuring rod 22 (accessory), a relative milli-
metre scale (±50 cm) is applied at the top.
Its zero height (90–210 cm) can be selected on the ex-
tension. In this manner, deviations from the reference
height can be read off directly.

Laser Viewing Glasses
The laser viewing glasses filter out the ambient light.
As a result, the red light of the laser appears brighter
to the eye.
The laser viewing glasses (accessory) are not pro-
s
tective glasses against laser radiation. Do not use
them as protective glasses against strong sun light
or in traffic.
Working with a Tripod (Accessory)
The unit has a 5/8" tripod connection 10 for each of
the horizontal and vertical operating positions.
For tripods 27 with a millimetre scale on the extension,
the height offset can be set directly.
Operation with Wall Mount (Accessory)
A
For work exceeding the extension height of tripods,
the unit can be operated with the wall mount 24. At-
tach the wall mount 24 to the wall.
Working Examples
Projecting Horizontal Heights/Points
B
Place the unit in the horizontal position on a firm base
or use a tripod 27.
Working with a tripod: Adjust the laser beam to the de-
sired height. Select rotation operation or transfer the
height by hand in point operation by turning the rota-
tion head 13.
Working without a tripod: Determine the height differ-
ence between the laser beam and the height line at the
reference point with the aid of the measuring plate 25,
turn the rotation head 13 to the target location and
transfer the measured height difference.
Parallel Alignment
C
In case right angles are to be indicated or partitions are
to be aligned ,the laser beam is to be aligned parallel,
i.e. equidistant to a reference line (e.g. wall, expansion
joint).
For this purpose, place the unit in the vertical position
and align so that the beam runs approximately parallel
to the reference line.
For the exact positioning, measure directly at the unit
the distance between the laser beam and the wall with
the measuring plate 25. Then at the longest distance
possible away from the unit, measure the distance
again between the laser beam and the wall. Adjust the
laser beam with the aid of the right 19 or left 18 direc-
tion buttons so that it has the same distance to the wall
as that measured directly at the unit.
