animals can be injured by the ejected saw
blade.

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
machine to the dust extraction.
Mount the dust cover 18 onto the machine in such
a manner that the holders in the centre 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 machine model, place a vacu-
um hose 20 (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
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
extraction 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.
