Inserting the Saw Blade (see figure A)
If required, remove the dust cover 17 (see "Dust
Cover").
Insert the saw blade 14 (teeth in cutting direction) into
the stroke rod until it latches 16.
While inserting the saw blade, pay attention that the
back of the saw blade is positioned in the groove of
the guide roller 13.

Note: If the grooves of the saw blade holder are not
in the position shown in the figure or when the Preci-
sion-Control guide cheeks 12 are closed, then the
saw blade 14 cannot be inserted into the stroke rod
16. Briefly press the SDS clamping lever 18 toward
the side and release it again.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to injuries.
Ejecting the Saw Blade (see figure B)
When ejecting the saw blade, hold the ma-
chine in such a manner that no persons or an-
imals can be injured by the ejected saw blade.
Press the SDS clamping lever 18 sideward to the
stop. The Precision-Control guide cheeks 12 are
released and the saw blade 14 is ejected.
Dust/Chip Extraction
Dusts from materials such as lead-containing coat-
ings, some wood types, minerals and metal can be
harmful to one's health. Touching or breathing-in
the dusts can cause allergic reactions and/or lead
to respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.

Dust Cover
Mount the dust cover 17 before connecting the
machine to the dust extraction.
Mount the dust cover 17 onto the machine in such a
manner that the holders in the centre of the dust cover
engage on the contact protector 15.
For work without dust extraction, the dust cover 17
can be removed. To remove the dust cover 17, grasp
it by the side and pull it off toward the front.
Connecting the Dust Extraction (see figure C)
Mount the vacuum connection 6 into the opening of
the base plate 8. Make sure that the plastic tip of the
vacuum connection engages into the corresponding
opening on the housing as shown in the figure.
Place a vacuum hose 5 (accessory) onto the vacuum
connection 6. Connect the vacuum hose 5 with a vac-
uum cleaner (accessory).
Switch the saw dust blower off when a dust extraction
system is connected (see "Sawdust Blower Device").
To enable optimum dust extraction, use the splinter
guard 20 if possible.
The vacuum cleaner must be suitable for the material
being worked.
When vacuuming dry dust that is especially detrimen-
tal to health or carcinogenic, use a special vacuum
cleaner.
Splinter Guard (see figure D)
The splinter guard 20 (accessory) can prevent fraying
of the surface while sawing wood. The splinter guard
can only be used for certain saw blade types and only
for cutting angles of 0°. When sawing with the splin-
ter guard, the base plate 8 must not be moved back
for cuts that are close to the edge.
Press the splinter guard 20 from below into the base
plate 8 (with the notch facing upward as shown in the
figure).
The splinter guard 20 can be inserted into the base
plate in 2 positions. For narrow saw blades, insert the
splinter guard fully to the front; for wider saw blades,
insert it further to the rear in the base plate 8.
When using the sliding shoe 7, the splinter guard 20
is not inserted into the base plate 8, but into the slid-
ing shoe.
Sliding Shoe
When working surfaces that are easily scratched, the
sliding shoe 7 can be attached onto the base plate 8
in order to prevent the surface from being scratched.
To attach the sliding shoe 7, insert it at the front of the
base plate 8, push the rear part upward and allow it to
latch.
