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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing 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
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.

(see Fig. A1 – A4)
Attach the dust box 2 onto the extraction outlet

To empty the dust box 2, press the latching
levers 6 on the side of the dust box ( ). Pull off

Before opening the dust box 2, it is recommend-
ed to loosen the dust from the filter element by
gently striking it against a firm support (as shown

Note: To ensure optimum dust extraction, empty
the dust box 2 in good time and clean the filter
element 7 at regular intervals.
When working vertical surfaces, hold the power
tool in such a manner that the dust box 2 faces
downward.
External Dust Extraction (see figure C)
Slide the extraction adapter 9 onto the outlet
piece 5. Ensure that the latching levers of the
extraction adapter engage. The extraction
adapter 9 accepts a vacuum hose with a diameter
of 19 mm.
The vacuum cleaner must be suitable for the
material 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 detri-
mental 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 faces
downward.
For removal of the extraction adapter 9, press
the latching levers together at the rear and pull
the extraction adapter off.
