To ensure constant air circulation, always keep the
cooling-air openings in the motor housing clean
and free of blockages.
The machine is equipped with self-disconnecting
special carbon brushes. If they are worn, power is
interrupted automatically and the machine comes
to a standstill.
• Clean the tabletop insert [20.1] regularly and
remove wood chips, dust deposits and workpiece
offcuts from the extraction channel on the chip
defl ector (see Fig. 10).
9.1 Adjusting the laser (KS 120 EB only)
If the laser beams do not line up with the cutting
edge, you can adjust both of the lasers.
Use an Allen key screwdriver (size 2.5) to do
this.
- Pierce the points (3.2 to 3.7) marked on the
sticker using the Allen key screwdriver to reveal
the adjusting screws located underneath.
• The laser beam factory settings are correct. Only
turn the adjusting screws when indicated.
- Place a test workpiece on the machine to check
the laser.
- Cut a groove in the workpiece.
- Swivel the saw head upwards and check the
setting.
Laser beam is not visible
• First check whether the laser is switched on.
If not, press the button (2.1) to switch on the
laser.
Identify which laser beam is not visible.
- Turn the adjusting screws for the left (3.3) and
right (3.5) laser until the laser beam shines on
the workpiece.
- As described, fi rst (a) adjust the laser beam so
it is parallel with the scribe line, then (b) adjust
the inclination angle and fi nally (c) adjust the
axial displacement of the laser beam.
a) Laser beam is not parallel with the
scribe line [Fig. 3A]
Adjust until parallel.

no longer strays off line when workpieces are
trimmed.

9.2 Correcting horizontal mitre angles
If the pointer (13.2) no longer rests on the preset
mitre angle values, you can loosen the screw (13.1)
and readjust the pointer.
If the actual (sawn) mitre cut deviates from the
preset value, you can correct this value accord-
ingly:
– Engage the saw unit in the 0° position.
– Loosen the three screws (13.3) that secure the
scale to the saw table.
– Slide the scale together with the saw unit until
the actual value is 0°. You can check this by set-
ting an angle between the stop ruler and the saw
blade.
– Tighten the three screws (13.3) again.
– Check the angle setting by making a test cut.
9.3 Correcting vertical mitre angles
If the actual value no longer corresponds with
the preset value, you can correct this value ac-
cordingly:
– Engage the saw unit in the 0° position.
– Open both screws (23.1).
– Swivel the saw unit until the actual value is 0°.
You can check this by setting an angle between
the saw table and the saw blade.
– Tighten the two screws (23.1) again.
– Check the angle setting by making a test cut.
If the pointer (22.2) no longer rests on the preset
value, you can loosen the screw (22.1) and readjust
this value.
9.4 Replacing the tabletop insert
Never work with a worn table insert (20.1), replace
it with a new one.
– To replace the table insert, unscrew the six
screws (20.2).
