Dust/Chip Extraction
f
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)
Attach the dust box
4
onto the extraction outlet
7
until it latches.
While attaching the dust box, make sure that the
holder
8
engages into the corresponding open-
ing of the machine.
To empty the dust box
4
, press the latching
levers
9
on the side of the dust box (
n
). Pull off
the dust box toward the bottom (
o
).
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.
