Dust/Chip Extraction

Avoid touching or breathing-in dusts that are
harmful to one's health or carcinogenic. Al-
ways use suitable dust extraction, work in
well ventilated areas and wear appropriate
protective equipment. When disposing of
dusts, pay attention that you or other per-
sons do not come into contact with these
dusts. Dusts dangerous to one's health devel-
op, e.g., when sanding lead-containing coat-
ings, chemically treated woods or some met-
als.

To empty the dust box 6, press the latching
levers 14 on the side of the dust box ( ). Pull off
the dust box toward the bottom ( ).
Before opening the dust box 6, it is recommend-
ed to loosen the dust from the filter element by
gently striking it against a firm support (as shown

Grasp the dust box 6 by the recessed grip, fold
the filter element 15 upward and empty the dust
box. Clean the thin plates of the filter element 15
with a soft brush.
External Dust Extraction (see figure D)
Slide the extraction adapter 16 onto the outlet
piece 13. Ensure that the latching levers of the
extraction adapter engage. The extraction

ter of 19 mm.
For removal of the extraction adapter 16, press
the latching levers together at the rear and pull
