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 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.
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 4 forward so that "I" is indicated on
the switch. Immediately after switching on,
the tool sends a laser beam out of each 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 4 backward so that "0" is indicated on
the switch. When switching off, the leveling
unit is locked.
Setting the Automatic Switch-off
By default, the tool automatically shuts off 20
minutes after being switched on. The
automatic switch-off can be set from 20
Influences on Accuracy
The ambient temperature has the greatest
influence. Especially temperature differences
occurring from the ground upward can divert
the laser beam.
As thermal fluctuation is largest close to the
ground, the tool, if possible, should be
mounted on a commercially available tripod
and placed in the center of the working area.
Operation
minutes to 8 hours. For this, switch the tool
on, then immediately off, and then on again
within 4 s. To confirm the change, all laser
beams will flash quickly for 2 s after
switching on the second time.
• Do not leave the switched on tool
unattended and switch the tool off after
use. Other persons could be blinded by the
laser beam. When switching on the tool the
next time, the automatic switch-off is set to
20 minutes again.
Working with Automatic Leveling
Position the tool on a level and firm support,
attach it to the holder 8 or to the tripod 18.
After switching on, the automatic leveling
function automatically compensates
irregularities within the self-leveling range
from ±6° (longitudinal axis) and ±4° (lateral
axis). The leveling is finished as soon as the
laser points do not move any more.
If the automatic leveling function is not
possible, e.g. because the surface on which
the tool stands deviates by more than 6° (or
4° from the horizontal plane) the laser beams
flash rapidly.
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 ±6° or ±4° respectively, all
laser beams light up continuously again.
In case of ground vibrations or position
changes during operation, the tool is
automatically levelled in again. To avoid
errors by moving the tool, check the position
of the laser beams with regard to the
reference points upon re-leveling.
Working Advice
• Always use the center of the laser point
for marking. The size of the laser point
changes with the distance
Leveling Accuracy
Apart from exterior influences, device-
specific influences (such as heavy impact or
falling down) can lead to deviations.
Therefore, check the accuracy of the tool
each time before starting your work.
Should the tool exceed the maximum
deviation during one of the tests, see
recalibration procedure or have it
recalibrated by a Bosch after-sales
service center.
