–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.

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.
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.
9.1 Adjusting the laser
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.

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.

Right laser beam
c) Laser beam is not positioned on
the cut [Fig. 3C]
Adjust the axial displacement.

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
accordingly:
–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 setting 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 accordingly:
–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.
