Application Example - Bosch GRL900-20HV Operating/Safety Instructions Manual

Note: Due to inertia, it is possible for the
laser to slightly move beyond the end point of
the laser line.
Rotating the laser line/laser dot or the
rotational plane is possible only with the
remote control.
When the laser tool is in the horizontal
position, the laser line (in line operation)
or the laser dot (in point operation) can be
positioned within the rotational plane of the
laser.
Press button 4c to rotate in clockwise
direction, and button 5c to rotate in counter-
clockwise direction. In rotational operation,
pressing the buttons has no effect.
When the rotational laser is in the vertical
position, it is possible to rotate the laser
point, laser line or rotational plane around the
vertical axis. Rotating is possible only within
the self-leveling range (5° toward the left or
right).
Press button 4c to rotate in clockwise
direction, and button 5c to rotate in counter-
clockwise direction.
Turning the Rotational Plane when in the
Vertical Position (see figure L)
To align the vertical laser line or the rotational
plane against a reference point on a wall,
Keep the remote control clean at all times.
Do not immerse the remote control into
water or other fluids.
Wipe off debris using a moist and soft
cloth. Do not use any cleaning agents or
solvents.
If the remote control should fail despite
the care taken in manufacture and
testing, repair should be carried out by
an authorized customer services agent
for Bosch power tools. Do not open the
remote control yourself.

Reset Shock-warning
Function
The laser level has a shock-warning function;
after position changes or shock to the laser
tool, or in case of ground vibrations, it keeps
the laser tool from leveling in at changed
heights, and thus prevents vertical errors.
Switching the shock-warning function on and
off is possible only on the laser tool. Once
the shock-warning function has actuated, is
can be restarted via the remote control.
After actuation of the shock-warning function,
the rotation of the laser is stopped, the laser
flashes, the leveling indicator goes out, and
the shock-warning indicator flashes red. The
current operating mode is stored.
After the shock-warning function has
actuated, press the shock warning reset
button 3c. The shock-warning function is
restarted and the rotational laser starts
leveling. As soon as the laser tool is levelled
in (the leveling indicator on the laser tool
continuously lights up green), it starts in
the stored operating mode. Now, check the
height of the laser beam with a reference
point and correct the height, if required.
set up the laser tool in the vertical position,
and roughly align the laser line or the
rotational plane with the reference point. For
precise alignment with the reference point,
press button 4c (clockwise rotation) or 5c
(counterclockwise rotation).
In all correspondence and spare parts
orders, please always include the 10-digit
article number given on the type plate of
the remote control.
ENVIRONMENT PROTECTION
