Mounting/Replacing a Sanding Sheet on the Sanding Plate
The sanding plate 14 is fitted with Velcro backing for quick
and easy fastening of sanding sheets with Velcro adhesion.
Before attaching the sanding sheet 15, free the Velcro back-
ing of the sanding plate 14 from any debris by tapping against
it in order to enable optimum adhesion.
Selecting the Sanding Sheet
Depending on the material to be worked and the required rate of material removal, different sanding sheets are available:
Sanding disc Material
– All wooden materials
(e. g., hardwood, soft-
wood, chipboard, build-
ing board)
– Metal materials
– Paint
– Varnish
– Filling compound
– Filler
Dust/Chip Extraction
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.

onto the machine via the tool holder 8. Turn the dust extrac-
tion 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 machine with the retaining clip 17
as shown in the figure.
