Initial Operation
Protect the tool against moisture and direct
sun irradiation.
Do not subject the 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 tool to
adjust to the ambient temperature before operation. In case of extreme
temperatures or variations in temperature the accuracy of the tool can
be impaired.
Avoid heavy impact or falling of the tool. After heavy exterior impact
on the tool, an accuracy check should always be carried out before
continuing to work (see “Leveling Accuracy”).
Switch the tool off during transport. Push the On/Off switch 1
downward to the “Off” position when transporting the measuring tool.
This locks the leveling unit, which can be damaged in case of intense
movement.
Switching On and Off
Do not leave the switched on tool
unattended and switch the tool off after use.
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 on the tool, push the On/Off switch 1 upward. Immediately
after switching on, the measuring tool sends two laser beams out of the
exit opening 2.
