Starting Operation
Protect the measuring
tool from moisture and
direct sunlight.
Do not expose the
measuring tool to any
extreme temperatures or fluctuations in
temperature. The precision of the
measuring tool may be compromised if
exposed to extreme temperatures 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 temperature, first allow the
measuring tool to adjust to the ambient
temperature and then always carry out an
accuracy check before continuing work (see
“Leveling Accuracy”, page 14).
Avoid substantial knocks
to the measuring tool
and avoid dropping it. Always carry out an
accuracy check before continuing work if
the measuring tool has been subjected to
severe external influences (see “Leveling
Accuracy”, page 14).
Switch the measuring
t o o l o f f w h e n
transporting it. The pendulum unit is locked
when the tool is switched off, as it can
other wise be damaged by extreme
movements.
Switching On/Off
To switch on the measuring tool, slide the
on/off switch (4) to the “On” position. As
soon as it is switched on, the measuring
tool emits laser beams from the laser beam
outlet window (1).
Do not direct the laser
beam at persons or
animals and do not stare into the laser
beam yourself (even from a distance).
To switch off the measuring tool, slide the
on/off switch (4) to the Off position. The
pendulum unit is locked when the tool is
switched off.
N e v e r l e a v e t h e
m e a s u r i n g t o o l
unattended when 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 45 °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.
Operation
Inserting/Changing the batteries
It is recommended that you use alkaline
manganese batteries to operate the
measuring tool.
Press the locking mechanism (7) upwards
to open the battery compartment cover
(8) and remove the battery compartment
cover. Insert the batteries.
When inserting the batteries, ensure that
the polarity is correct according to the
illustration on the inside of the battery
compartment.
The battery indicator (2) always indicates
the current status of the battery. If the
batteries are running low, the laser lines
will gradually become dimmer. If the
batteries are almost empty the battery
indicator starts flashing continuously and
the laser lines will blink every 5 min for
5 s until the tool turns off. If the batteries
are empty, the laser lines and the battery
indicator will flash once before the
measuring tool switches off.
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 are not using it for a
prolonged period of time. The batteries
can corrode and self-discharge during
prolonged storage in the measuring tool.
