Selecting the Sanding Sheet
Depending on the material to be worked and the required rate
of material removal, different sanding sheets are available:
For the working of all wooden
materials
For coarse-sanding, e. g. of rough,
unplaned beams and boards
For face sanding and planing small
irregularities
For finish and fine sanding of hard
woods
For the working of paint/enamel
coats or primers and fillers
For sanding off paint
For sanding primer
For final sanding of primers before
coating
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.

placing it down.
The removal capacity during sanding is mainly determined by
the selection of the sanding sheet.
Only flawless sanding sheets achieve good sanding capacity

Pay attention to apply uniform sanding pressure; this increas-

es the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an in-

crease of the sanding capacity, but to increased wear of the
machine and the sanding sheet.

A sanding sheet that has been used for metal should not be
used for other materials.
