Press the speed selection button 4 to start the rotational
operation. The tool starts with the lowest rotational
speed. Pressing button 4 again increases the speed in
steps (50, 200, 600 and 0 rpm).
When working with the receiver, the highest rota-
tional speed is recommended.
When working without laser receiver, reduce the rota-
tional speed or use the laser viewing glasses for impro-
ved visibility of the laser beam.
Point operation
This operating mode provides the best
visibility of the laser beam; it is used for
projecting heights or for checking buil-
ding lines.
This operating mode provides the best visibility of
the laser beam; it is used for projecting heights or for
checking building lines.
Set the rotational speed to 0 rpm in order to access
point operation.
Pressing and holding the up 8/down 7 arrow button
on the tool, or the right 20/left 21 arrow button on
the remote control, makes the laser beam oscillate,
meaning the laser operates with an aperture angle
of approx. 3°.
Press the buttons mentioned to position the laser
beam in the circle.
When a button is pressed and held, the beam at first
moves slowly, and then quickly after 4 seconds.
Scan Operation
n this operation mode, the laser beam
moves back and forth within a sector of
a circle. The visibility of the laser beam
is increased in comparison to rotational
operation. It is possible to choose bet-
ween five angles.
Press the Scan button 11 to start scan operation.
The tool starts at an aperture angle of 8° and with
high oscillating frequency. Pressing button 11 again
increases the aperture angle via 45° and 90° to
180° with decreasing oscillating frequency.
The laser line can be moved within the circle by pres-
sing the up 8/down 7 arrow button on the tool or
the right 20/left 21 arrow button on the remote con-
trol.
To variably increase or decrease the scan zone
area, press and hold the up 8/down 7 arrow button
on the remote control while in the horizontal positi-
on.
Standby Operation
Press and hold the manual button 9 for
three seconds to activate standby opera-
tion. (Energy-saving function)
In standby mode, the laser beam, rotor,
self-levelling system and LEDs are switched
off; the height alarm remains activated.
The battery charge-control indicator 5 flashes every
4 seconds.
Press and hold the manual button 9 for three se-
conds to deactivate standby operation and restore
full operability of the laser.

Automatic Levelling

After switching on, the tool automatically detects the
horizontal or vertical position. To change the positi-
on, shut the tool off, reposition it and switch on
again.
After switching on, the unit checks the horizontal or
vertical position and compensates automatically for
inclinations within the self-levelling range of approx.
8 % ( ± 0,8 m/10 m).
When the tool is inclined by more than 8 %, levelling
is no longer possible. The rotor is stopped, the laser
beam flashes and the indicators 3 and 10 flash 1 x
per second.
When the laser is not within the levelling range for
more than 10 minutes, the tool is completely swit-
ched off.
Small Position Changes
Minor position changes of up to 3 mm max. are au-
tomatically compensated. The selected operating
mode is not interrupted. Thus, ground vibrations or
weather impact are automatically compensated.
Major Position Changes (Height Alarm)
The automatic levelling system triggers the height
alarm:
– when the laser operates for more than 5 minutes
in horizontal position at a speed of 600 rpm and
the position is disturbed.
– when the laser tries to re-level itself after shock or
impact, and the height has changed by more than
3 mm (out-of-level shutoff).
The laser and rotor are switched off. The manu-
al/height alarm (HI) warning indicator 10 flashes
2 x per second.
To delete the height alarm, switch the laser off and
then on again. Check the original reference height
after the laser has re-levelled itself again.
