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 18 before connecting the
power tool to the dust extraction.
Mount the dust cover 18 onto the machine in such
a manner that the holders in the center of the
dust cover engage on the contact protector 16.
For work without dust extraction, the dust cover
18 can be removed. To remove the dust cover 18,
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 power tool model, place a
vacuum hose 20 (accessory) either directly onto
the vacuum connection 7 or cut off the old hose
1 609 929 N52 | (12.3.08)
end, screw the extraction adapter 6 (accessory)
onto the hose end and insert it directly into the
vacuum connection 7. Connect the vacuum hose
20 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 ex-
traction system is connected (see "Sawdust
Blower Device").
To enable optimum dust extraction, use the
splinter guard 21 if possible.
The vacuum cleaner must be suitable for the ma-
terial 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 21 (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.
Press the splinter guard 21 from below into the
base plate 9 (with the notch facing upward as
shown in the figure).
The splinter guard 21 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 9.
When using the sliding shoe 8, the splinter
guard 21 is not inserted into the base plate 9,
but into the sliding shoe.
Sliding Shoe
When working surfaces that are easily scratched,
the sliding shoe 8 can be attached onto the base
plate 9 in order to prevent the surface from being
scratched.
To attach the sliding shoe 8, insert it at the front
of the base plate 9, push the rear part upward
and allow it to latch.
