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”).
• Switch the tool off during transport.
Switch off the leveling unit, which can be 
damaged in the case of intense movement.
Turning on the Tool 
To switch on the tool, push the On/Off
switch 1once. Immediately after switching
on, the tool sends one laser beam out of the
exit opening 3.
• 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 tool, push the On/Off
switch 1four more times. When switching off,
the levelling unit is locked.
•Do not leave the switched on tool 
unattended and switch the tool off after 
use. Other persons could be blinded by the 
laser beam.
Automatic Leveling
Working with Automatic Leveling
Position the tool on a level and firm surface,
hold it by the b against a vertical surface or
attach it to a tripod 8.
After switching on, the leveling function
automatically compensates irregularities
within the self-leveling range of ±4°. The
leveling is finished as soon as the laser
beams do not move any more. The indicator
2lights up green.
If the automatic leveling function is not
possible, e. g. because the surface on which
the tool stands deviates by more than 4°
from the horizontal plane, the indicator 2
lights up red and the lasers automatically
begins to flash. In this case, bring the tool to
the level position, and wait for the self
leveling to take place. As soon as the tool is
within the self-leveling range of ±4° again,
the indicator 2lights up green and the laser
beams are switched on.
