Danger of injury due to defective compo-
nents! The product must only be put into
operation if no defects are found. Ensure
that any defective parts are replaced before
the product is used again.
WARNING! Risk of injury due to laser beam!
Never direct the laser beam towards people,
other living creatures or reflecting surfaces.
Check the device:
• Make sure all parts are fitted on the machine
firmly.
• Check whether there are any visible defects:
broken parts, cracks, etc.
• Check the accuracy when it is the first time you
are using the laser or when the laser has not
been checked for accuracy in a while.
• Also check the accuracy when the laser may
have been dropped.
Self- levelling mode (Fig. A, D1)
The lasers are aligned automatically by the pen-
dulum so that the vertical and horizontal lines are
displayed level on the wall.
1. Place the laser on a flat surface or fit it to the
universal clamp (7) or tripod (not included) and
fasten it as described above.
2. Slide the lock switch (2) to the left to switch the
device on. The operating mode button (1) is illu-
minated in green. If the operating mode button
(1) is illuminated in red and the laser flashes,
the permissible inclination range of 5 degrees is
exceeded. Position the device horizontally until
the operating mode button lights green.
3. To switch off, slide the lock switch to the right.
The laser switches off and the pendulum will be
locked.
Switch the measuring tool off when
transporting it. The pendulum unit is locked
when the tool is switched off, as it can
otherwise be damaged.
Manual mode (Fig. A, D2)
The laser can be aligned manually to the angle you
require, to enable for example a diagonal line to be
displayed.

1. Place the laser on a flat surface or fit it to the
universal clamp (7) or tripod (not included) and
fasten it as described above.
2. Check if the lock switch (2) is set to the right. If
not, slide the lock switch (2) to the right.
3. Press the operating mode button (1) to switch
the laser on and the operating mode button (1)
lights up red, because the pendulum is blocked.
4. Now you can tilt the laser to the angle you re-
quire, so that the lines are displayed diagonally
on the wall as shown in Fig. D2.
5. To switch off , press the operating mode button
(1).
5. MAINTENANCE
Accuracy check
Only the centre of the laser line must be
used for marking. The width of the laser line
changes depending on the distance.
Quick horizontal line check (Fig. A, E1)
1. Set the device at approximately 5 meters from
the wall.
2. Slide the lock switch (2) to the left to switch the
device on. The operating mode button (1) is illu-
minated in green. If the operating mode button
(1) is illuminated in red and the laser flashes,
the permissible inclination range of 5 degrees is
exceeded. Position the device horizontally.
3. After it self-levels, make a horizontal mark on the
wall as shown in figure E1. Label this as point A.
4. Turn the laser 2.5 m to the right.
5. Turn the laser on, and after it self-levels, make a
horizontal mark on the wall. Label this as point
B as shown in figure E1. When points A and
B are more than 2.5mm apart from a vertical
perspective, a calibration check is necessary.
Quick vertical line check (Fig. A, E2):
1. Set the device at approximately 5 meters from
the wall.
2. Hang a 2.5 meter rope on the wall with a weight
on the end of the rope as shown in figure E2.
The rope must be able to swing freely.
3. Slide the lock switch (2) to the left to switch the
device on. Position the vertical line next to the
wire. The operating mode button (1) is illumi-
nated in green. If the operating mode button (1)
is illuminated in red and the laser flashes, the
permissible inclination range of 5 degrees is
