Operation
Initial Operation
Protect the measuring tool against moisture and direct
sun irradiation.
Do not subject the measuring tool to extreme tempera-
tures 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.
Avoid heavy impact to or falling down of the measuring
tool. Damage to the measuring tool can impair its accuracy.
After heavy impact or shock, compare the laser line with a known
horizontal or vertical reference line.
Switching On and Off
To switch on the measuring tool, push the On/Off switch 15. Imme-
diately after switching on, the measuring tool sends a laser beam out
of the exit opening 9.
Do not point the laser beam at persons or animals and do
not look into the laser beam yourself, not even from a
large distance.
To switch off the measuring tool, push the On/Off switch 15 again.
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.
