The battery indicator (2) always indicates the current bat-
tery status:
LED
Capacity
Green continuous light
100−75 %
Yellow continuous light
75−35 %
Red continuous light
35−10 %
No light
Batteries drained
If the batteries are running low, the laser lines will gradually
become dimmer.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Operation
Starting Operation
Protect the measuring tool from moisture and direct
u
sunlight.
Do not expose the measuring tool to any extreme tem-
u
peratures or fluctuations in temperature. For example,
do not leave it in a car for extended periods of time. If it
has been subjected to significant fluctuations in temper-
ature, first allow the measuring tool to adjust to the ambi-
ent temperature and then always carry out an accuracy
check before continuing work (see "Accuracy Check of
the Measuring Tool", page 15).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
Avoid substantial knocks to the measuring tool and
u
avoid dropping it. Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page 15).
Switch the measuring tool off when transporting it.
u
The pendulum unit is locked when the tool is switched off,
as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (7)
to the " On" position (for working with the pendulum lock)
or to the "
On" position (for working with automatic level-
ling). As soon as it is switched on, the measuring tool emits
laser lines from the outlet apertures (1).
Do not direct the laser beam at persons or animals and
u
do not stare into the laser beam yourself (even from a
distance).
To switch off the measuring tool, slide the on/off switch (7)
to the Off position. The pendulum unit is locked when the
tool is switched off.

Never leave the measuring tool unattended when
u
switched on, and ensure the measuring tool is
switched off after use. Others may be blinded by the
laser beam.
If the maximum permitted operating temperature of 40 °C is
exceeded, the tool shuts down to protect the laser diode.
Once it has cooled down, the measuring tool is operational
again and can be switched back on.
If the temperature of the measuring tool is approaching the
maximum permissible operating temperature, the laser lines
will gradually become dimmer.
Deactivating the Automatic Shut-Off Function
If no button on the measuring tool is pressed for approx.
120 min, the measuring tool will automatically switch itself
off to preserve battery life.
To switch the measuring tool back on after it has been auto-
matically switched off, you can either slide the on/off switch
(7) to the "Off" position first and then switch the measuring
tool back on, or press either the laser mode button (6) or the
receiver mode button (4) once.
To deactivate the automatic shut-off function, hold down the
laser mode button (6) for at least 3 s (with the measuring
tool switched on). If the automatic shut-off function is deac-
tivated, the laser beams will flash briefly as confirmation.
To activate the automatic shut-off function, switch the meas-
uring tool off and on again.
Deactivating the Signal Tone Function
The signal tone function is always activated once the meas-
uring tool is switched on.
To deactivate or activate the signal tone function, simultan-
eously press the laser mode button (6) and the receiver
mode button (4) and hold them down for at least 3 s.
Three short signal tones will sound as confirmation both
when the signal tone function is activated and deactivated.
Operating Modes
The measuring tool has several operating modes which you
can switch between 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 and two vertical laser
planes.
After you switch it on, the measuring tool generates a hori-
zontal laser plane. To change the operating mode, press the
laser mode button (6).
All operating modes can be selected with both automatic lev-
elling or the pendulum lock.
Receiver Mode
Receiver mode must be activated when working with the
laser receiver (18), regardless of which operating mode is
selected.
In receiver mode, the laser lines flash at a very high fre-
quency, enabling them to be detected by the laser receiver
(18).
