Operation
Initial Operation
Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or var-
iations in temperature. As an example, do not leave it in vehicles for
long time. In case of large variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature before putting it into oper-
ation. 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. Dam-
age to the measuring tool can impair its accuracy. After heavy impact or
shock, compare the laser lines with a known horizontal or vertical refer-
ence line.

transporting the measuring tool. This locks the levelling unit, which
can be damaged in case of intense movement.

til the automatic levelling indicator 6 goes out. Slide the automatic levelling
switch 2 into position to lock the levelling unit .
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.

tery life.
