Selecting the Sanding Sheet
Depending on the material to be worked and the required rate of material removal, different sanding
sheets are available:
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.
Connecting the Dust Extraction (see figure A)
Remove the application tool/accessory when
mounting the dust extraction
18
(accessory).
If required, assemble the parts of the dust extrac-
tion
18
as shown in the figure. Position the as-
sembled dust extraction onto the machine via the
tool holder
7
. Turn the dust extraction in such a
manner that the cams of the dust extraction en-
gage into the corresponding recesses on the
housing. Fasten the dust extraction to the ma-
chine with the retaining clip
16
as shown in the
figure.
Pay attention that the felt ring
15
is undamaged
and faces tightly against the sanding plate
12
.
Replace a damage felt ring immediately.
Place a vacuum hose
19
(accessory) onto the
vacuum connection
17
. Connect the vacuum
hose
19
with a vacuum cleaner (accessory). An
overview for the connection of various vacuum
cleaners can be found at the end of these instruc-
tions.
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.
