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 18).
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 18).
Switch the measuring tool off when
transporting it. The pendulum unit is
locked when the tool is switched off, as it can otherwise be
damaged by extreme movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (2) to
the “ON” position. As soon as it is switched on, the measuring
tool emits laser beams from the outlet apertures (1).
