Operation
Initial Operation
• Loud audio signals will sound under
certain conditions while operating the
tool. Therefore, keep the tool away from
your ear or other persons. The loud
audio signal can cause hearing damage.
Protect the tool against moisture and
direct sun light.
• 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 dropping 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, slide the On/Off
switch 7 to the “ on”. position (when
working without automatic levelling) or to the
“ on” position (when working with
automatic levelling). Immediately after
switching on, the tool sends laser beams out
of the exit openings 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, slide the On/Off
switch 7 to the “off” position. When switching
off, the levelling unit is locked.
When exceeding the maximum permitted
operating temperature of 45 °C, the tool
switches off to protect the laser diode. After
cooling down, the tool is ready for operation
and can be switched on again.
Deactivating the Automatic Shut-off
When no button on the tool is pressed for
approx. 30 minutes, the tool automatically
switches off to save the batteries.
To switch on the tool after automatic shut-off,
either slide the On/Off switch 7 to the “off”
position and then switch the tool on again or
press the operating mode button 4 once or
press teh pulse-function button 3 once.
To deactivate the automatic shut-off, keep
the operating mode button 2 pressed for at
least 3 s (while the tool is switched on).
Deactivation of the automatic shut-off is
confirmed by brief flashing of the laser
beams.
• Do not leave the switched on tool
unattended and switch the tool off after
use.
To activate the automatic shut-off, switch the
tool off and then on again.
Deactivating the Signal Tone
After the tool has been switched on,the audio
signal is always activated.
To deactivate/activate the audio signal, press
and hold the operating mode button 4 and
the pulse-function button 3 at the same time
for at least 3 s.
The audio signal activation and deactivation
are both confirmed by three short beeps.
Operating Modes
The tool has three operating modes between
which you can switch at any time:
– Horizontal operation: generates a
horizontal laser plane.
– Vertical operation: generates a vertical
laser plane.
– Cross-line operation: generates a
horizontal and vertical laser plane.
After switching on, the tool is in horizontal
operation. Press the operating mode button
4 to change the operating mode.
All three operating modes can be selected
either with or without automatic levelling.
Pulse Function
When working with the laser receiver 17,
the pulse function must be activated,
–independent of the selected operating
mode.
In pulse function, the laser lines flash at very
high frequency and thus become detectable
by the laser receiver 17.
To switch on the pulse function, press button
3. When the pulse function is switched on,
the pulse-function indicator 5 lights up green.
-8-
When the pulse function is switched on, the
visibility of the laser lines is reduced for the
human eye. Therefore, shut off the pulse
function by pushing button 3 again when
working without laser receiver. When the
pulse function is switched off, the pulsefunction indicator 5 is deactivated.
Automatic Leveling
Working with Automatic Leveling
Position the tool on a level and firm support,
attach it to the holder 19 or to the tripod 21.
When working with automatic levelling, push
the On/Off switch 7 to the “ on” position.
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.
If automatic leveling is not possible, e.g.
because the surface on which the tool stands
deviates by more than 4° from the horizontal
plane, the laser lines begin to flash rapidly.
When the audio signal is activated, a fastbeat signal sounds for 30 s (maximum). This
alarm is deactivated within 10 s after
switching on, in order to allow adjustment of
the tool.
Set up the tool in level position and wait for
the self-leveling to take place. As soon as the
tool is within the self-leveling range of ±4°, all
laser beams light up continuously and the
audio signal is switched off.
In case of ground vibrations or position
changes during operation, the tool is
automatically levelled in again. To avoid
errors, check the position of the horizontal
and vertical laser
line with regard to the reference points upon
releveling.
Working without Automatic Leveling
For working without automatic leveling, slide
the On/Off switch 7 to the “ on” position.
When automatic leveling is switched off,
indicator 6 lights up red and for the first 30 s
laser beams flash slowly.
When the automatic leveling is switched off,
the tool can be held by hand or placed on an
inclined surface. In cross-line operation, the
two laser lines do not necessarily run at a
right angle to each other.
Working Advice
• Always use the center of the laser point
for marking. The size of the laser point
changes with the distance.
Leveling Accuracy
Influences on Accuracy
The ambient temperature has the greatest
influence. Especially temperature differences
occurring from the ground upward can divert
the laser beam.
Because the largest difference in
temperature layers is close to the ground,
the tool should always be mounted on a
tripod when distances exceeding 20 m. If
possible, also set up the tool in the center of
the work area.
Apart from exterior influences, devicespecific 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.
Firstly, check the leveling accuracy of the
horizontal laser line and then the leveling
accuracy of the vertical laser line.
Should the tool exceed the maximum
deviation during one of the tests, please
have it repaired by a Bosch after-sales
service.
Checking the Horizontal Leveling
Accuracy.
A free measuring distance of 16 ft on a firm
surface in front of two walls A and B is
required for the check.
– Mount the tool onto a tripod, or place it
on a firm and level surface close to the
wall A. Switch the tool on. Select crossline operation with automatic leveling.

16 ft (5m)
– Direct the laser against the close wall A
and allow the tool to level in. Mark the
center of the point where the laser lines
cross each other on the wall (point I).

and mark the cross point of the laser lines
on the opposite wall B (point II).
– Without turning the tool, position it close to
wall B. Switch the tool on and allow it to
level in.
– Align the height of the tool (using a tripod
or by underlaying, if required) in such a
manner that the cross point of the laser
lines is projected against the previously
marked point II on the wall B.
32ft x ±0.0024in/ft = ±5/64 (0.078 in)
Thus, the difference d between points I and
III must not exceed 5/64 in (max.).
Checking the Leveling Accuracy of the
Vertical Line
For this check, a door opening is required
with at least 8 ft of space (on a firm surface)
to each side of the door.
– Position the tool on a firm, level surface
(not on a tripod) 8ft away from the door
opening. Allow the tool to level in while in
vertical operation with automatic leveling,
and direct the laser beam at the
door opening.
– Mark the center of the vertical laser line at
the floor of the door opening (point I), at a
distance of 8ft beyond the other side
of the door opening (point II) and at the
upper edge of the door opening (point III).
– Without changing the height, turn around
the tool by 180°. Direct it against the wall A
in such a manner that the vertical laser line
runs through the already marked point I.
Allow the tool to level in and mark the
cross point of the laser lines on the wall A
(point III).
– The difference d of both marked points I
and III on wall A results in the actual height
deviation of the tool alongside the
lateral axis.
On the measuring distance of 2 x 16ft = 32ft,
the maximum allowable deviation is:
– Rotate the tool by 180° and position it on
the other side of the door opening directly
behind point II. Allow the tool to level in
and align the vertical laser line in such a
