Initial Operation
• Loud audio signals will sound under
certain conditions while operating the
tool. Therefore, keep the tool away from
your ear or other persons. The loud audio
signal can cause hearing damage.
• Protect the tool against moisture and
direct sun light.
• Do not subject the tool to extreme
t e m p e r a t u r e s o r v a r i a t i o n s i n
temperature. As an example, do not
leave it in vehicles for extended periods
of time. In case of large fluctuations in
temperate, allow the tool to adjust to the
ambient temperate and then perform an
accuracy check before continuing work (see
"Leveling Accuracy" section, page 15). In
case of extreme temperatures or variations
in temperature, the accuracy of the tool can
be impaired.
• Avoid heavy impact or dropping of the
tool. After heavy exterior impact on the
tool, an accuracy check should always be
carried out before continuing to work (see
"Leveling Accuracy").
• Switch the tool off during transport.
When switching off, the leveling unit, which
can be damaged in case of intense
movement, is locked.

unattended and switch the tool off after
use.
To switch on the tool, slide the On/Off
switch 16 to the "
working without automatic leveling) or to the
"
on" position (when working with automatic
leveling). Immediately after switching on,
the tool sends laser beams out of the exit
openings 1.
To switch off the tool, slide the On/Off switch
16 to the " off " position. When switching off,
the leveling unit is locked.
When exceeding the maximum permitted
operating temperature of 104°F, the tool
switches off to protect the laser diode. After
cooling down, the tool is ready for operation

Operation
and can be switched on again.
Automatic Shut-off
When no button on the tool is pressed for
approx. 120 minutes, the tool automatically
switches off to save the batteries.
To switch on the tool after automatic shut-off,
either slide the On/Off switch 16 to the "off"
position and then switch the tool on again or
press the operating mode button 7 once or
press the receiver mode button 5 once.
Deactivating the Automatic Shut-off
To deactivate the automatic shut-off, keep the
operating mode button 7 pressed for at least 3
s (while the tool is switched on). Deactivation
of the automatic shut-off is confirmed by brief
flashing of the laser beams.
Activating the Automatic Shut-off
To activate the automatic shut-off, switch the
tool off and then on again.
Deactivating the Signal Tone
After the tool has been switched on,the audio
signal is always activated.
To deactivate/activate the audio signal, press
and hold the operating mode button 7 and
the receiver mode button 5 at the same time
for at least 3 s.
The audio signal activation and deactivation
are both confirmed by three short beeps.
The tool has several operating modes
between which you can switch at any time:
– Generating a horizontal laser plane,
– Generating a vertical laser plane,
t h e
– Generating two vertical laser planes,
t o o l
– Generating a horizontal laser plane as
well as two vertical laser planes.
After switching on, the tool generates
a horizontal laser plane. To change the
operating mode, press the operating mode
button 7.
All operating modes can be selected with or
without automatic leveling.
Receiver Mode
When working with the laser receiver 25,
the receiver mode must be activated, –
independent of the selected operating mode.
In receiver mode, the laser lines flash at very
high frequency and thus become detectable
by the laser receiver 25.
