Interior angle
– Open the clamp (18.2).
– Place the bevel with the two legs (18.1)
against the interior sides of the corner.
– Close the clamp (18.2).
– Place the bevel with one leg on a stop ruler
attached to the circular cross-cut saw.
– To set the dissecting angle (horizontal mitre
angle), swivel the saw unit until the laser
beam is congruent with the line (19.1) on
the bevel.
Exterior angle
– Open the clamp (18.3).
– Slide the aluminium profi le (18.4) on both
legs forwards.
– Place the bevel with the two legs (18.4)
against exterior sides of the corner.
– Close the clamp (18.3).
– Slide back the aluminium profi le on both
legs.
– Place the bevel with one leg on a stop ruler
attached to the circular cross-cut saw.
– To set the dissecting angle (horizontal mitre
angle), swivel the saw unit until the laser

Service and maintenance

Always pull the plug out of the socket
before performing any type of work
on the machine!
All maintenance and repair work
which requires the motor housing to
be opened, must only be carried out
by an authorised service workshop.
Damaged safety devices and parts
should be repaired or replaced by
an authorised service centre unless
otherwise specifi ed in the operating
instructions.
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-discon-
necting 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 chan-
nel 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 un-
derneath.
• The laser beam factory settings are cor-
rect. 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.
Left laser beam
Right laser beam
b) Laser beam strays off line when
workpiece trimmed towards the
left or right [Fig. 3B]
Adjust the inclination angle until the laser
beam no longer strays off line when work-
pieces are trimmed.
Left laser beam
Right laser beam
c) Laser beam is not positioned on
the cut [Fig. 3C]
Adjust the axial displacement.
