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
For sanding, always connect dust extraction.
Place a vacuum hose
4
(accessory) onto the vac-
uum connection
3
. Connect the vacuum hose
4
with a vacuum cleaner (accessory). An overview
for the connection of various vacuum cleaners
can be found at the end of these instructions.
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.
