Working Instructions for the Laser
Receiver
Marking
When the laser beam runs through the center of
the reception area 31, its height can be marked
at the centre mark 30 right and left on the laser
receiver. The centre mark is located 45 mm
away from the top edge of the laser receiver.
Aligning with the Spirit Level
The laser receiver can be aligned vertically
(plumb line) with the spirit level 25. A laser
receiver attached out-of-level leads to faulty
measurements.
Attaching with the Holder (see figure A)
With the holder 40, the laser receiver can be fas-
tened to a construction laser measuring rod 38
(accessory) as well as to other auxiliary tools
with a width of up to 65 mm.
Screw the holder 40 to the retainer opening 33
on the rear side of the measuring tool with fas-
tening screw 39.
Loosen the locking screw 36, slide the holder
onto the construction laser measuring rod 38,
for example, and retighten the locking screw 36.
The holder 40 can be horizontally aligned with
help of the spirit level 41.
The upper edge 37 of the holder is located at the
same height as the centre mark 30 and can be
used for marking of the laser beam.
Attaching with the Magnet (see figure B)
When a positive-lock attachment is not absolute-
ly required, the laser receiver can be attached to
steel parts via the face side using the magnet
plate 29.

Work Examples

Projecting/Checking Heights (see figure D)
Position the measuring tool in the horizontal
position onto a firm support or mount it onto a
tripod 48 (accessory).
Working with tripod: Align the laser beam to the
requested height. Project or check the height at
the target location.
Working without tripod: Determine the height
difference between the laser beam and the
height at the reference point with help of the
measurment plate 44. Project or check the meas-
ured height difference at the target location.
Parallel Alignment of a Plumb Beam/
Projecting Right Angles (see figure E)
When right angles are to be projected or when
partitions are to be aligned, the plumb beam 9
must be aligned parallel, meaning at the same
distance to a reference line (e.g. a wall).
For this, set up the measuring tool in the vertical
position and position it in such a manner that
the plumb beam runs approximately parallel to
the reference line.
For exact positioning, measure the clearance
between plumb beam and reference line direct-
ly on the measuring tool with help of the meas-
urment plate 44. Measure the clearance be-
tween plumb beam and reference line again as
far away as possible from the measuring tool.
Align the plumb beam in such a manner that it
has the same clearance to the reference line as
when measured directly at the measuring tool.
The right angle to the plumb beam 9 is indicated
by the variable laser beam 6.
Indicating a Plumb Line/Vertical Plane
(see figure F)
To indicate a plumb line or a vertical plane, set
up the measuring tool in the vertical position.
When the vertical plane is supposed to run at a
right angle to a reference line (e.g. a wall), then
align the plumb beam 9 with this reference line.
The plumb line is indicated by the variable laser
beam 6.
