Turning the Rotational Plane in
When the laser level is in the vertical position, it
is possible to rotate the rotational plane around
the X-axis for easy sighting out or parallel
alignment in a range of ±8%. To activate the
function, press the button for dual-axis slope
Overview
After switching on, the laser tool automatically
detects the horizontal or vertical position.
To change between horizontal and vertical
position, switch the laser tool off, reposition it
and switch on again.
After switching on, the laser tool checks
the horizontal and vertical position and
automatically levels out any unevenness within
the self-leveling range of approx. 8% (4.6°).
When the laser tool is inclined by more than
8% after switching on or after a position
change, leveling in is no longer possible. In
this case, the rotor is stopped, the laser off
and leveling indicator 5 continuously lights
up red. Switch the laser tool off, reposition it,
switch it on again and wait for it to re-level.
When the laser tool is leveled automatic
re-leveling takes place after position changes.
The rotor stops during the leveling process,
the laser beam is off, and the leveling
indicator 5 flashes green.
Shock-warning Function
ground vibrations, it prevents the laser tool
from leveling at changed heights, and thus
prevents vertical errors.
The shock warning function is ON by default
every time the laser tool is switched on. ADS
is active 30 seconds after device is leveled.
When the ADS is enabled the shock-warning
indicator 11 is turned off.
After a position change or when heavy ground
vibrations are detected, the shock-warning
function is triggered: The rotation stops, the
laser off, the leveling indicator 5 goes out, and
the shock-warning indicator 11 flashes red.

operation 2 on the laser level twice or the but-
ton for dual-axis slope operation 10a on the
remote control followed by the Y lower/upper
direction button. The Y leveling indicator LED 5
will start flashing red. Press the Y lower/upper
direction button 4 or 12 until the required posi-
tion is reached.
The current operating mode is stored.
After the shock-warning function has been
triggered, press the power button 1 shortly to
reset it.
The shock-warning function is restarted and
the laser tool starts leveling. As soon as
the laser tool is leveled (leveling indicator 5
continuously lights up green), it starts in the
stored operating mode. Now, align the laser
beam with a reference point and correct the
position, if required.
To switch off the shock-warning function,
press the power button 1 shortly once, or,
when the shock warning is triggered (shock-
warning indicator 11 flashing red) press the
power button shortly twice. When the shock-
warning function is turned off, the shock
warning indicator 11 lights up red.
Accuracy Check
Influences on Accuracy
The ambient temperature has the greatest
influence on accuracy. Especially temperature
differences occurring from the ground upward
can divert the laser beam.
In addition to external influences, device
specific influences (e.g. falls or heavy impacts)
can also lead to deviations. For this reason,
check the accuracy each time before beginning
work.
The deviations play a role in excess of approx.
65 ft (20 m) distance and can easily reach two
to four times the deviation at 330 ft (100 m).
Because the largest difference in temperature
layers is close to the ground, the laser tool
should always be mounted on a tripod when
operating at distances exceeding 65 ft (20 m). If
possible, also set up the laser tool in the center
of the work area.
If the laser tool exceeds the maximum deviation
in one of the four measuring procedures, have
it checked by a Bosch customer service center.
