Initial Operation - Bosch GRL 400 H Mode D'emploi

Initial Operation

• Protect the tool
direct sun irradiation.
• Do not subject
temperatures or variations in temperature.
As an example, do not leave it in vehicles for
longer periods. In case of large variations in
temperature, allow the tool to adjust to the
ambient temperature
operation. In case of extreme temperatures
or variations in temperature, the accuracy of
the tool can be impaired.
• Avoid heavy impact or and prevent the
tool from falling. After heavy exterior impact
on the tool, an accuracy check should always
be carried out before continuing to work (see
"Leveling Accuracy").
Setting Up the Tool
Position the laser tool on a firm surface or mount it to a
tripod.
Due to the high leveling accuracy, the
laser tool reacts sensitively to ground vibrations and position
changes. Therefore, pay attention that the position of the
laser tool is stable in order to avoid operational interruptions
due to re-leveling.
Turning on the Tool
• Do not direct the laser beam at persons
or animals (especially not at their eye
level), and do not stare into the laser
beam yourself
distance). Immediately
the laser tool sends out the laser beam 4.
Automatic leveling
Overview
After switching on, the laser tool checks the horizontal
and vertical position and automatically levels out any
unevenness within the self-leveling range of approx. 8 %
(5°).
When the laser tool is inclined by more than
8 % after switching on or after a position
change, leveling in is no longer possible. In this case, the
rotor is stopped, the laser flashes and leveling indicator 1

2. The indicators 1, 3 and 6 light up briefly. The laser
and
tool immediately starts the automatic leveling. During the
leveling, the leveling indicator 1 lights up green and the
laser flashes in point operation.
The laser tool is leveled in as soon as leveling indicator 1
lights up green continuously and the laser beam is steady.
After the leveling is completed, the laser tool automatically
starts in rotational operation.

The laser tool exclusively operates with fixed rotational
speed in rotational operation, which is also suitable for use
of a laser receiver.
When factory set, the shock-warning function is
automatically switched on, and the shock-warning indicator
3 lights up green.
Turning off the Tool
To switch off the laser tool, press the On/Off button 2
again. When the shock warning has activated (shock-
warning indicator 3 flashes red), press the On/Off button
once to restart the shock-warning function, and then again
to switch off the tool.
• Do not leave the switched on laser tool
unattended and switch the laser tool off
after use.
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

wait for it to re-level. Without repositioning, the laser is
automatically switched off after 2 minutes and the laser
tool after 2 hours.
When the laser tool is leveled in, it continuously checks the
horizontal and vertical position.
