Initial Operation; Working Advice - Bosch GRL2000-40H Operating/Safety Instructions Manual

Initial Operation

Protect the laser tool
against moisture and
direct sun irradiation.
Do not subject the laser tool to extreme
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 before putting it into
operation. In case of extreme temperatures or
variations in temperature, the accuracy of the
tool can be impaired.
It is the user's responsibility to periodically
check the accuracy of the laser tool
as work progresses. Always check the
accuracy of the laser tool after it has
been dropped or subject to extreme
temperatures and temperature variations.
Avoid heavy impact and prevent the laser
tool from falling. After heavy exterior impact
on the laser tool, an accuracy check should
always be carried out before continuing to
work (see "Leveling Accuracy").
If glass lighthouse breaks
when dropped, broken
glass can cause laceration hazard and unit to
loose its IP rating. Contact customer service
immediately.
Setting Up the Laser Tool
Horizontal Position
*GRL2000-40HV only
Set up the laser tool on a sturdy surface in the
horizontal or vertical position; mount it on a
tripod 21 or to the wall mount with alignment
unit 25.
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

animals and do not stare into the laser
beam yourself, not even from a large
distance.
Do not leave the switched on laser tool
unattended and switch the laser tool off
after use. Serious eye injury could result from
the laser beam.
Immediately after switching on, the laser tool
sends out the vertical plumb beam 8 and the
variable laser beam 6.
For switching on the laser tool, press the On/
Off button 1. The indicators 5, 10 and 11 light
up briefly. The laser tool immediately starts
the automatic leveling. During the leveling, the
leveling indicators 5 flash green.
The laser tool is leveled in as soon as leveling
indicators 5 light up green continuously and
the laser beam is turned on. After the leveling
is completed, the laser tool automatically
starts in rotational operation.
With the operating mode buttons 3 and 13,
the operating modes can already be specified
during leveling (see "Operating Modes, page
15). In this case, the laser tool starts in the set
operating mode upon completion of leveling.
For GRL2000-40HV in vertical mode the Y
leveling indicator LED is off by de fault, unless
it has been tilted/moved from its default
position.
To switch off the laser tool, long press the
On/Off button 1 again.
Vertical Position*
• Do not leave the switched on laser tool
Always use the center of the laser point for
marking. The size of the laser point changes
with the distance.
