Fitting individual components
– Carefully remove all parts included in the delivery from
their packaging.
– Remove all packing material from the power tool and the
accessories provided.
– Make sure that you remove the packaging material be-
neath the motor block.
The following parts of the tool are attached directly to the
housing: Anti-kickback pawls (7), ring spanner (35), hook
spanner/open-ended spanner (36), angle guide (3), parallel
guide (9), additional parallel guide (47) with fastening
set (48), protective cover (6), push stick (15), saw
blade (28).
– If you require one of these parts, remove it carefully from
its storage location.
Fitting the Riving Knife (see figures c)
Note: If necessary, clean all parts to be fitted before you po-
sition them.
– Remove the table insert (8) if necessary.
– Turn the crank (17) clockwise as far as possible so that
the saw blade (28) is in the highest possible position
above the saw table.
– Loosen the bolt (40) using the ring spanner (35).
– Insert the riving knife (27) and push it down as far as pos-
sible.
– Re-tighten the bolt (40) using the ring spanner (35).
– Fit the table insert (8).
Fitting the table insert (see figure d)
– Hook the table insert (8) into the rear recesses (41) of
the tool chamber.
– Guide the table insert down.
– Press down on the table insert until it engages in the front
of the tool chamber.
Fitting the anti-kickback pawls (see figure e)
In the event of a kickback, the anti-kickback pawls (7) pre-
vent the workpiece from being flung towards the operator.
The pawls' sharp teeth dig into the surface of the workpiece
and hold it back.
– Press the anti-kickback pawls' (7) pushbutton (42) to-
gether.
This pulls back the guide pin.
– Guide the anti-kickback pawls (7) over the riving
knife (27) and release the pushbutton (42).
– Slide the anti-kickback pawls towards the protective
cover until the guide pin engages in the rear hole at the
top of the riving knife.
– Check that the guide pin is firmly connected to the hole
and that the anti-kickback pawls are functioning properly.
Carefully lift the anti-kickback pawls. When released, the
spring-loaded pawls must go down and touch the table in-
sert.

Fitting the parallel guide (see figure f)
The parallel guide (9) can be positioned on either the left or
the right of the saw blade.
– Loosen the clamping handle (43) of the parallel guide
(9). This lightens the load on the V guide (44).
– First insert the parallel guide with the V guide into the
guide groove (45) of the saw table. Then position the par-
allel guide in the front guide groove (46) of the saw table.
The parallel guide can now be moved freely.
– To secure the parallel guide, push the clamping handle
(43) down.
Fitting the additional parallel guide (see figure g)
To saw narrow workpieces and bevel angles, you must fit
the additional parallel guide (47) on the parallel guide (9).
The additional parallel guide can be fitted on the left or right
of the parallel guide (9) as required.
Use the "additional parallel guide" fastening set (48) (two
fastening screws, two wing nuts) for fitting the guide.
– Slide the fastening screws through the lateral holes on the
parallel guide (9).
– The heads of the screws are used to guide the additional
parallel guide.
– Slide the additional parallel guide (47) over the heads of
the fastening screws.
– Tighten the screws using the wing nuts.
Fitting the angle guide (see figure h1-h2)
– Push the rail (49) of the angle guide (3) into one of the
guide grooves (5) provided in the saw table.
To make it easier to position long workpieces, the angle
guide can be extended with the profile rail (50).
– If necessary, fit the profile rail on the angle guide using
the wing nuts (51).

Dust/chip extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
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.
