Operation
Starting Operation
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or fluctuations in
u
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 measur-
ing tool to adjust to the ambient temperature and then always carry out an accuracy
check before continuing work (see "Accuracy Check of the Measuring Tool",
page 45).
The precision of the measuring tool may be compromised if exposed to extreme tem-
peratures or fluctuations in temperature.
Avoid substantial knocks to the measuring tool and avoid dropping it. Always
u
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 45).
Switch the measuring tool off when transporting it. The pendulum unit is locked
u
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 (10) to the "ON" position. As
soon as it is switched on, the measuring tool emits laser lines from the outlet
apertures (4).
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
To switch off the measuring tool, slide the on/off switch (10) to the OFF position. The
pendulum unit is locked when the tool is switched off.
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be blinded by the laser beam.
If the temperature of the measuring tool is approaching the maximum permissible oper-
ating temperature, the laser lines will gradually become dimmer.
If the maximum permitted operating temperature is exceeded, the laser lines will flash
rapidly before the measuring tool switches off. Once it has cooled down, the measuring
tool is operational again and can be switched back on.
