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
putting it into operation. In case of extreme
temperatures or variations in temperature,
the accuracy of the tool can be impaired.
• Avoid heavy impact or and prevent the
tool from falling. After heavy exterior
impact on the tool, an accuracy check
should always be carried out before
continuing to work (see "Leveling
Accuracy").

Set up the laser tool on a sturdy surface in the
horizontal or vertical position; mount it on a tripod
21 or to the wall mount with alignment unit 25.
Due to the high leveling accuracy, the laser tool
reacts sensitively to ground vibrations and position
changes. Therefore, pay attention that the position
of the laser tool is stable in order to avoid
operational interruptions due to re-leveling.
Turning on the Tool
• Do not direct the laser beam at persons
or animals (especially not at their eye
level), and do not stare into the laser
beam yourself (not even from a
distance). Immediately after switching on,
the laser tool sends out the vertical
plumb beam 9 and the variable laser
beam 6.
For switching on the laser tool, press the
On/Off button 4. The indicators 1, 3 and 12
light up briefly. The laser tool immediately
starts the automatic leveling. During the
leveling, the leveling indicator 3 lights up
green and the laser flashes in point operation.
The laser tool is leveled in as soon as leveling
indicator 3 lights up green continuously and
the laser beam is steady. After the leveling is
completed, the laser tool automatically starts
in rotational operation.
