Indicating a Plumb Line/Vertical Plane (see figure E)
To indicate a plumb line or a vertical plane, set up the measur-
ing tool in the vertical position. When the vertical plane is sup-
posed to run at a right angle to a reference line (e.g. a wall),
then align the plumb beam 9 with this reference line.
The plumb line is indicated by the variable laser beam 6.
Turning the Rotational Plane when in the Vertical Position
(see figure F)
To align the vertical laser line or the rotational plane against a
reference point on a wall, set up the measuring tool in the ver-
tical position, and roughly align the laser line or the rotational
plane with the reference point. For precise alignment with the
reference point, press button 28 (clockwise rotation) or but-
ton 29 on the remote control (anticlockwise rotation).
Working without Laser Receiver (see figure G)
Under favourable light conditions (dark environment) and for
short distances, it is possible to work without the laser receiv-
er. For better visibility of the laser beam, either select line op-
eration, or select point operation and manually rotate the ro-
tation head 10 to the target location.
Overview of Indications

Levelling in or re-levelling
Measuring tool levelled in/ready for operation
Self-levelling range exceeded
Shock-warning function activated
Shock warning actuated
Battery voltage for ≤2 h operation
Battery empty

Maintenance and Service

Maintenance and Cleaning
Keep the rotational laser level, battery charger and remote
control clean at all times.
Do not immerse the rotational laser level, battery charger and
remote control into water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any
cleaning agents or solvents.
Particularly clean the surfaces at the outlet opening of the ro-
tational laser level regularly and pay attention for any lint.

Working with the Laser Receiver (see figure H)
Under unfavourable light conditions (bright environment, di-
rect sunlight) and for larger distances, use the laser receiver
for improved finding of the laser beam. When working with
the laser receiver, select rotational operation with the highest
rotational speed.
Measuring Over Long Distances (see figure I)
When measuring over long distances, the laser receiver must
be used to find the laser beam. In order to reduce interferenc-
es, the measuring tool should always be set up in the centre of
the work surface and on a tripod.
Working Outdoors (see figure J)
The laser receiver should always be used when working out-
doors.
– When working on unstable ground, mount the measuring
tool onto the tripod 37. Activate the shock-warning func-
tion in order to avoid faulty measurements in case of
ground vibrations or shock to the measuring tool.
