Bosch GRL2000-40HV Operating Instructions Manual page 21

Indicating a Plumb Line/Vertical
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 8 with this
reference line.
The plumb line is indicated by the variable
laser beam 6.
Working without Laser Receiver
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, select
line operation or point operation, and rotate
the beam with the direction buttons on the
tool 4 and 12 or the remote control.

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
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.
