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
Replacing the Sanding Plate (see figure G)

Working Advice
 Wait until the machine has come to a standstill before
placing it down.
 Before any work on the machine itself, pull the mains
plug.
The removal capacity during sanding is mainly determined by
the selection of the sanding sheet.
Only flawless sanding sheets achieve good sanding capacity
and extend the service life of the machine.
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-
Grain size
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.
