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 environ-
ment) 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 rotate the rotation head 10 to the
target location.

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.
Measuring Over Long Distances
(see figure E)
When measuring 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 surface 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 faulty
measurements in case of ground vibrations or
shock to the laser tool.
