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.
• Avoid heavy impact or falling of the
tool. Damage to the tool can impair its
accuracy.After heavy impact or shock,
compare the laser line with a known
horizontal or vertical reference line.
• Switch the tool off during transport.
When switching off, the leveling unit,
which can be damaged in case of intense
movement, is locked.
Switching On and Off
To switch on the tool, push the On/Off
switch 3 to the "On" position. Immediately
after switching on, the tool sends two laser
beams out of the exit opening 1.
• 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 3 to the "Off" position. 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 (see
figures A-B)
Position the tool on a level and firm support,
hold it by the contact surfaces 6 against a
vertical surface or attach it to a tripod 11.
Operation
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
2 lights 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 laser is automatically
switched off. In this case, bring the tool to
the level position or hold it by the contact
surfaces 6 straightly against a vertical
surface, and wait for the selfleveling to take
place. As soon as the tool is within the self-
leveling range of ±4° again, the indicator 2
lights up green and the laser beams are
switched on.
When not within the self-leveling range of
±4°, working with the tool is not possible,
because it cannot be assured that the laser
beams run at a right angle to each other.
In case of ground vibrations or position
changes during operation, the tool is
automatically leveled in again. To avoid
errors, check the position of the horizontal
and vertical laser line with regard to the
reference points upon re-leveling.
Working Advice
• Always use the center of the laser line
for marking. The width of the laser line
changes with the distance.
