Note: If the grooves of the saw blade holder are
not in the position shown in the figure, then the
saw blade 14 cannot be inserted into the stroke
rod 12. Briefly press the SDS clamping lever 17
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 inju-
ries.
Ejecting the Saw Blade (see figure B)
When ejecting the saw blade, hold the ma-
chine in such a manner that no persons or
animals can be injured by the ejected saw
blade.
Press the SDS clamping lever 17 sideward to the
stop. The saw blade 14 is released and ejected.

Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered 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 work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.

Dust Cover
Mount the dust cover 16 before connecting the
machine to the dust extraction.
Mount the dust cover 16 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
16 can be removed. To remove the dust cover
16, grasp it by the side and pull it off toward the
front.
Connecting the Dust Extraction
(see figures C–E)
Mount the vacuum connection 7 into the open-
ing of the base plate 9. Make sure that the plas-
tic tip of the vacuum connection engages into
the corresponding opening on the housing as
shown in the figure.
Depending on the machine model, place a vacu-
um hose 18 (accessory) either directly onto the
vacuum connection 7 or cut off the old hose
end, screw the extraction adapter 6 (accessory)
onto the hose end and insert it directly into the
vacuum connection 7. Connect the vacuum hose
18 with a vacuum cleaner (accessory). An over-
view for the connection of various vacuum
cleaners can be found at the end of these in-
structions.
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 19 if possible.
The vacuum cleaner must be suitable for the
material being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Splinter Guard (see figure F)
The splinter guard 19 (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 splinter guard, the base
plate 9 must not be moved back for cuts that are
close to the edge.
