working without automatic levelling) or to the
" on" position (when working with automatic
levelling). Immediately after switching on, the
measuring tool sends laser beams out of the exit
openings 1.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
To switch off the measuring tool, slide the
On/Off switch 7 to the "off" position. When
switching off, the levelling unit is locked.
When exceeding the maximum permitted oper-
ating temperature of 45 °C, the measuring tool
switches off to protect the laser diode. After
cooling down, the measuring tool is ready for
operation and can be switched on again.
Deactivating the Automatic Shut-off
When no button on the measuring tool is pressed
for approx. 30 minutes, the measuring tool auto-
matically switches off to save the batteries.
To switch on the measuring tool after automatic
shut-off, either slide the On/Off switch 7 to the
"off" position and then switch the measuring
tool on again or press the operating mode but-
ton 4 once or press the pulse-function button 3
once.
To deactivate the automatic shut-off, keep the
operating mode button 4 pressed for at least 3 s

tivation of the automatic shut-off is confirmed
by brief flashing of the laser beams.
Do not leave the switched on measuring
tool unattended and switch the measuring
tool off after use. Other persons could be
blinded by the laser beam.
To activate the automatic shut-off, switch the
measuring tool off and then on again or press

Operating Modes

The measuring tool has several operating modes
between which you can switch at any time.
These are for:
– Generating a horizontal laser plane,
– Generating a vertical laser plane,
– Generating two vertical laser planes,
– Generating a horizontal laser plane as well as
After switching on, the measuring tool generates
a horizontal laser plane. To change the operating
mode, press the operating mode button 4.
All operating modes can be selected both with

Pulse Function
When working with the laser receiver 17, the
pulse function must be activated, – independ-
ent of the selected operating mode.
In pulse function, the laser lines flash at very
high frequency and thus become detectable by
the laser receiver 17.
To switch on the pulse function, press button 3.
When the pulse function is switched on, the
pulse-function indicator 5 lights up green.
When the pulse function is switched on, the vis-
ibility of the laser lines is reduced for the human
eye. Therefore, shut off the pulse function by
pushing button 3 again when working without
laser receiver. When the pulse function is
switched off, the pulse-function indicator 5 is
deactivated.
