if is caused by the machine itself, please send it to
an approved technical service.
• Wear safety glasses, hearing protectors and pro-
tective gloves.
• Before cutting into a partition, ceiling or floor,
make sure these do not contain any ducting.
• Before you use an accessory, make sure that its
maximum rotation speed is compatible with the
machine performance.
• Electric tools must not be used by under 16 year
olds.
• Do not cut into nails, screws, etc.
• Apply the machine to the material only after it has
been switched on.
• The cutting path must be free of obstacles on the
top and the bottom.
• Do not stick fingers in the sawdust ejector.
• Keep hand away from the rotating saw blade.
• Do not work overhead with the machine.
• Do not work with materials containing asbestos.
• Do not use a cracked or deformed circular saw
blade or one with missing or broken teeth.
• Do not use saw blades that have a thicker body
or the teeth is smaller than the thickness of the
kerf guide.
• The kerf guide has to be adjusted in case different
diameters of saw blade are used.
• Do not stop the saw blade after switching off with
side pressure.
• Never block the lower protective housing in the top
position; make sure that it always pivots freely.
• Never use circular saw blade made of high speed
steel (HSS).
• Always use the kerf guide.
• Never force a machine which seems to be labouring
or losing power; there may be a technical problem,
in which case continuing work could damage the
machine irrevocably. Whenever the machine does
not work properly, call an approved agent imme-
diately for a check. It may be advisable to tell the
technical agent or his representative why you are
calling him. This particularly applies in the case of
intermittent faults.
• Use only original parts and accessories.

(optional), to ours dusts collectors AS182K, AS282K
or to any other industrial collector. (Fig. 7)
7. ADJUSTING THE CUTTING ANGLE
The cutting angle is locked by means of knob E
(Fig. 8).
Loosen knob E, adjust the angle as required for the
work in question, retighten knob E.
8. LATERAL FENCE
Lateral fence is adjusted on the table and is tightened
with wing nut (Fig. 9).
9. FITTING SAW BLADES
• Release the hex key (Fig. 2) from its position.
• Open the blade protection housing.
• Block the blade rotation by means of a suitable
