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 (see figure G)
Rotating the laser line/laser dot or the
rotational plane is possible only with the
remote control.
When the rotational laser 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. Rotation is possible by 360°.
Press button 4A to rotate in clockwise
direction, and button 5A 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 4A to rotate in clockwise
direction, and button 5A to rotate in counter-
clockwise direction.
Application Example
Turning the Rotational Plane when in the
Vertical Position (see figure H)
To align the vertical laser line or the
rotational plane against a reference point on
a wall, set up the rotational laser in the
vertical position, and roughly align the laser
Maintenance and Cleaning
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.

RC1 Maintenance and Service
Reset Shock-warning Function
The rotational laser has a shock-warning
function; after position changes or shock to
the rotational laser, or in case of ground
vibrations, it keeps the rotational laser from
leveling in at changed heights, and thus
prevents vertical errors.
Switching the shock-warning function on and
off is possible only on the rotational laser.
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 3A. The shock-warning function is
restarted and the rotational laser starts
leveling. As soon as the rotational laser is
levelled in (the leveling indicator on the
rotational laser 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.
line or the rotational plane with the reference
point. For precise alignment with the
reference point, press button 4A (clockwise
rotation) or 5A (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.
