Operating Modes - Bosch GRL250HV Consignes De Fonctionnement/Sécurité

With the operating mode buttons 5 and 11,
the operating modes can already be specified
during leveling in (see "Operating Modes,
page 11). In this case, the laser tool starts in
the set operating mode upon completion of
leveling in.
Turning off the Tool
To switch off the laser tool, press the On/Off
button 4 again.
• Do not leave the switched on
laser tool unattended and switch
the laser tool off after use.
Overview
All three operating modes are possible with the
laser tool in horizontal and vertical position.
Rotational Operation
Rotational operation is
especially recommended when
using the laser 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
Each time after switching on, the laser
tool is in rotational operation mode with
average rotational speed.
To switch from line operation to rotational ope-
ration, press the rotational operation button 5.
Rotational operation starts with average
rotational speed.
To change the rotational speed, press the
rotational operation button 5 again until the
To save the batteries, the laser tool is
automatically switched off when not within the
self-leveling range for more than 2 h or when
the shock warning is actuated for more than
2 h (see "Automatic Leveling, page 12).
Reposition the laser tool and switch it
on again.
Working Advice
Always use the center of the laser point for
marking. The size of the laser point changes
with the distance.

requested speed is reached.
When working with the laser receiver, the
highest rotational speed should be set. When
working without laser receiver, reduce the rota-
tional speed for improved visibility of the laser
beam and use the laser viewing glasses 24.
Line Operation, Point Operation
(10°/25°/50°, 0°)
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, observe the operating instructions of the
remote control.
