The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Replacing the Sanding Sheet
When attaching a new sanding sheet, remove any
dust or debris from the sanding plate 6 (e. g. with
a brush).
To ensure optimum dust extraction, pay atten-
tion that the punched holes in the sanding sheet
match with the holes in the sanding plate.
Sanding Sheets with Velcro Backing
(see figure A)
The sanding plate 6 is fitted with Velcro backing
for quick and easy fastening of sanding sheets
with Velcro adhesion.
Before attaching the sanding sheet 7, free the
Velcro backing of the sanding plate 6 from any
debris by tapping against it in order to enable op-
timum adhesion.
Position the sanding sheet 7 flush alongside one
edge of the sanding plate 6, then lay the sanding
sheet onto the sanding plate and press it against
it with a light turning motion in clockwise direc-
tion.
To remove the sanding sheet 7, grasp it at one of
the tips and pull it off from the sanding plate 6.
Sanding Sheets without Velcro Backing
(see figures B–D)
n Press the release button 8 and keep it de-
pressed.
o Guide the sanding sheet 7 to the stop under
the opened front clamping bracket 9 and let
go of the release button 8 again. Pay atten-
tion that the sanding sheet is clamped cen-
trally.
p Press the sanding sheet clamp 5 inward and
pivot it to the stop.
q Fold the sanding sheet 7 firmly around the
sanding plate. Guide the other end of the
sanding sheet 7 between the rear clamping
bracket and the red roller on the clamping
bracket 5.
r Hold the sanding sheet tensely and press the
clamping bracket 5 toward the sanding plate
to lock the sanding sheet.
Sanding sheets without holes, e. g. from rolls or
by the meter, can be punctured with the perfo-
rating tool 10 for use with dust extraction. For
this, press the machine with the mounted sand-
ing sheet onto the perforating tool (see figure E).
To remove the sanding sheet 7, loosen the
clamping bracket 5 and pull out the sanding
sheet from the rear holding fixture. Press the re-
lease button 8 and completely remove the sand-
ing sheet.
