Indicating a Plumb Line/Vertical
Plane (see figure B)
To indicate a plumb line or a vertical plane,
set up the laser 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.
Working without Laser Receiver
(see figure C)
Under favorable light conditions (dark
environment) and for short distances, it is
possible to work without the laser receiver.
For better visibility of the laser beam,
either select line operation, or select point
operation and manually (or by using the
remote control 20) rotate the rotation head
10 to the target location.

Applications
Working with the Laser Receiver
Under unfavorable light conditions (bright
environment, direct sunlight) and for
larger distances, use the laser receiver
for improved finding of the laser beam.
When working with the laser receiver,
select rotational operation with the highest
rotational speed.
Operating Over Long Distances
When operating over long distances, the
laser receiver must be used to find the laser
beam. In order to reduce interferences, the
laser tool should always be set up in the
center of the work area and on a tripod.
Working Outdoors (see figure F)
The laser receiver should always be used
when working outdoors.
When working on unstable ground, mount
the laser tool onto the tripod 21. Activate
the shock-warning function in order to avoid
errors in case of ground vibrations or shock
to the laser tool.
