Operating Modes - Bosch GRL800-20HV Operating/Safety Instructions Manual

Overview
All three operating modes are possible
with the laser tool in horizontal and vertical
position.
Rotational Operation

receiver. You can select
between different rotational
speeds.
Line Operation
In this operation mode, the
variable laser beam moves
within a limited aperture
angle. This increases the
visibility of the laser beam
in comparison to rotational
operation. You can select between different
aperture angles.
Point Operation
This operation mode enables
the best visibility of the
variable laser beam. As an
example, it is used for easy
projecting of heights or
checking building lines.
Rotation Mode
(150/300/600 min -1)
Each time after switching on, the laser
tool is in rotational operation mode at
default rotational speed (300 min -1).
To switch from line operation to rotational
operation, press the rotational operation
button 5.
Rotational operation starts at default
rotational speed (300 min -1).
To change the rotational speed, press the
rotational operation button 5 again until the
requested speed is reached.
When working with the laser receiver, the
highest rotational speed should be set. When
working without laser receiver, reduce the
rotational speed for improved visibility of
the laser beam and use the laser viewing
glasses 24.

Operating Modes

Line Operation, Point Operation
laser tool switches to line operation with the
smallest aperture angle.
To change the aperture angle, press the line
operation button 11. The aperture angle is
increased in two steps; at the same time, the
rotational speed is increased with each step.
When pressing the line operation button 11
a third time, the laser tool switches to point
operation after brief post-pulsation. Pressing
button 11 again takes you back to line
operation with the smallest aperture angle.
Note: Due to inertia, it is possible for the
laser to slightly move beyond the end point of
the laser line.
To position the laser line or the laser point
within the rotational plane, manually turn the
rotation head 10 to the requested position or
use the remote control 20.
Turning the Rotational Plane
when in the Vertical Position
When the laser tool is in the vertical position,
it is possible to rotate the laser point, laser
line or rotational plane around the vertical
axis with help of the remote control 20. For
this, follow the operating instructions of the
remote control.

To switch to line or point operation,
press the line operation button 11. The
