Selecting a sanding sheet
Different sanding sheets are available, depending on the ma-
terial you are working with and the required surface removal
rate:
For processing all wood and wood-based ma-
terials
For pre-sanding, e.g. of rough and un-
even beams and boards
For surface sanding and levelling of
slight irregularities
For finish-sanding and fine sanding of
hardwoods
For processing paint and lacquer layers or
primers such as fillers and bodyfillers
For sanding down paint
For sanding undercoats
For final sanding of primers prior to
painting

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.

Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
