diately.

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.
Integrated Dust Extraction with Dust Box
(see Fig. A1 – A4)

ing of the machine.

Before opening the dust box 4, it is recommend-
ed to loosen the dust from the filter element by
gently striking it against a firm support (as
shown in the figure).
Hold the dust box 4 firmly, fold the filter ele-
ment 10 upward and empty the dust box. Clean
the thin plates of the filter element 10 with a
soft brush.
Note: To ensure optimum dust extraction, emp-
ty the dust box 4 in good time and clean the fil-
ter element 10 at regular intervals.
When working vertical surfaces, hold the power
tool in such a manner that the dust box 4 faces
downward.
External Dust Extraction (see figure C)
Slide the extraction adapter 13 onto the outlet
piece 7. Ensure that the latching levers of the
extraction adapter engage. The extraction
adapter 13 accepts a vacuum hose with a diam-
eter of 19 mm.
The vacuum cleaner must be suitable for the ma-
terial being worked.
An overview for connecting to different vacuum
cleaners can be found at the end of these oper-
ating instructions.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
When working vertical surfaces, hold the power
tool in such a manner that the vacuum hose fac-
es downward.
For removal of the extraction adapter 13, press
the latching levers together at the rear and pull
the extraction adapter off.
