Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
The dust/chip extraction system can be blocked by dust,
chips or fragments of the workpiece.
– Switch the power tool off and pull the mains plug out of
the socket.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and eliminate it.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
To prevent the risk of fire when sawing aluminium,
u
empty the lower saw blade cover and do not use chip
extraction.
Cleaning the lower saw blade cover (see figure j)
You can open the lower saw blade cover (44) to remove
workpiece fragments and large chips.
– Switch the power tool off and pull the mains plug out of
the socket.
– Wait until the saw blade has come to a complete stop.
– Turn the power tool on its side.
– Open the base grid (31) (see figure a).
– Gently pull apart the tabs (45) of the lower saw blade
cover and open the lower saw blade cover (44).
– Remove workpiece fragments and chippings.
– Close the lower saw blade cover (44) again, making sure
that the tabs click into place (45).
– Close the base grid (31).
– Bring the power tool into the work position.
External dust extraction (see figure k)
– Firmly insert a suitable dust extraction hose into the dust
extraction adapter (29).
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Changing the saw blade (see figures l1−l4)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
When mounting the saw blade, wear protective
u
gloves. This poses a risk of injury.
Only use saw blades the maximum permitted speed of
u
which is higher than the no-load speed of the power
tool.

Only use saw blades that match the specifications
u
given in this operating manual and that are tested and
marked in accordance with EN 847-1
Only use saw blades that are recommended by the
u
power tool manufacturer and are suitable for use on
the material you want to saw. This prevents the saw
tooth tips from overheating and the plastic you want to
saw from melting.
Do not use HSS saw blades. Such saw blades can easily
u
break.
Removing the saw blade
– Open the clamping lever (37) and pull the protective
cover (3) out of the groove on the riving knife (4).
– Turn the locking screw (36) as far as possible in the "Un-
lock" direction using the tip of the ring spanner (9) and lift
the table insert (23) out of the tool chamber. A gripping
hole (46) is integrated into the tool for ease of lifting.
– Turn the crank (15) clockwise as far as possible so that
the saw blade (24) is in the highest possible position
above the saw table.
– Turn the clamping nut (47) using the ring spanner (9)
while pulling the spindle locking lever (48) until it en-
gages.
– Keep pulling the spindle locking lever and unscrew the
clamping nut anticlockwise.
– Remove the clamping flange (49).
– Remove the saw blade (24).
Fitting the saw blade
– If necessary, clean all the parts you want to fit before in-
stalling them.
– Place the new saw blade on the mounting flange (50) of
the tool spindle (51).
Note: Use sufficiently large saw blades. The radial clearance
between the saw blade and the riving knife must not exceed
3−8 mm (max.).
When fitting the saw blade, make sure that the cutting
u
direction of the teeth (direction of the arrow on the
saw blade) matches the direction of the arrow on the
riving knife.
– Fit the clamping flange (49) and the clamping nut (47).
– Turn the clamping nut (47) using the ring spanner (9)
while pulling the spindle locking lever (48) until it en-
gages.
– Tighten the clamping nut by turning it clockwise.
– Place the table insert (23) over the riving knife (4) and
into the tool chamber. Turn the locking screw (36) as far
as it will go in the "Lock" direction using the tip of the ring
spanner (9).
– Refit the protective cover (3) .
