Bosch 250 HV Originalbetriebsanleitung Seite 29

Do not leave the switched on measuring
tool unattended and switch the measuring
tool off after use. Other persons could be
blinded by the laser beam.
To save the batteries, the measuring tool is au-
tomatically switched off when not within the
self-levelling range for more than 2 h or when
the shock warning is actuated for more than 2 h
(see "Automatic Levelling of the Rotational La-
ser Level", page 30). Reposition the measuring
tool and switch it on again.
Operating Modes of the Rotational
Laser Level
Overview
All three operating modes are possible with the
measuring tool in horizontal and vertical position.
Rotational Operation
Rotational operation is especial-
ly recommended when using the
laser receiver. You can select be-
tween different rotational
speeds.
Line Operation
In this operation mode, the vari-
able laser beam moves within a
limited aperture angle. This in-
creases the visibility of the laser
beam in comparison to rotation-
al operation. You can select be-
tween different aperture angles.
Point Operation
This operation mode enables the
best visibility of the variable la-
ser beam. As an example, it is
used for easy projecting of
heights or checking building
lines.
Bosch Power Tools
Rotational Operation
(150/300/600 min
Each time after switching on, the measuring tool
is in rotational operation mode with average ro-
tational speed.
To switch from line operation to rotational oper-
ation, press the rotational operation button 5.
Rotational operation starts with average rota-
tional speed.
To change the rotational speed, press the rota-
tional operation button 5 again until the re-
quested speed is reached.
When working with the laser receiver, the high-
est rotational speed should be set. When work-
ing without laser receiver, reduce the rotational
speed for improved visibility of the laser beam
and use the laser viewing glasses 29.
Line Operation, Point Operation
(10°/25°/50°, 0°)
To switch to line or point operation, press the
line operation button 11. The measuring tool
switches to line operation with the smallest ap-
erture angle.
To change the aperture angle, press the line op-
eration button 11. The aperture angle is in-
creased in two steps; at the same time, the ro-
tational speed is increased with each step.
When pressing the line operation button 11 a
third time, the measuring 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 la-
ser line.
To position the laser line or the laser point with-
in the rotational plane, manually turn the rota-
tion head 10 to the requested position or use
the remote control 25.
