Due to the high levelling accuracy, the measuring tool reacts sensitively
to ground vibrations and position changes. Therefore, pay attention that
the position of the measuring tool is stable in order to avoid operational
interruptions due to re-levelling.
Operation
Starting Operation of the Cross-line Laser
Protect the measuring tool against moisture and direct sun
light.
Do not subject the measuring tool to extreme temperatures
or variations in temperature. As an example, do not leave it in
vehicles for longer periods. In case of large variations in temperature,
allow the measuring tool to adjust to the ambient temperature before
putting it into operation. In case of extreme temperatures or variations
in temperature, the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring tool.
After severe exterior effects to the measuring tool, it is recommended
to carry out an accuracy check (see "Accuracy Check of the Meas-
uring Tool" on page 24) each time before continuing to work.
Switching On and Off and Selecting Operating Modes
Do not point the laser beam at persons or animals and do not
look into the laser beam yourself, not even from a large dis-
tance.
Do not leave the switched on measuring tool unattended and
switch the measuring tool off after use. Other persons could be
blinded by the laser beam.
– To switch on the measuring tool, press the operating mode button 3.
