Sanding Sheets with Velcro Backing
(see figure C)
The sanding plate 9 is fitted with Velcro backing
for quick and easy fastening of sanding sheets
with Velcro adhesion.
Before attaching the sanding sheet 18, free the
Velcro backing of the sanding plate 9 from any
debris by tapping against it in order to enable op-
timum adhesion.
Position the sanding sheet 18 flush alongside
one edge of the sanding plate 9, then lay the
sanding sheet onto the sanding plate and press it
against it with a light turning motion in clockwise
direction.
To remove the sanding sheet 18, grasp it at one
of the tips and pull it off from the sanding plate 9.
Sanding Sheets without Velcro Backing
(see figure D)
Lightly lift and unlatch the sanding-sheet clamp
8.
Guide the sanding sheet 18 under the opened re-
ar clamping bracket 10 to the stop and clamp the
sanding sheet by reinserting the sanding-sheet
clamp 8.
Fold the sanding sheet 18 firmly around the san-
ding plate. Guide the other end of the sanding
sheet 18 under the open front clamping bracket
10 and clamp the sanding sheet by reinserting
the sanding-sheet clamp 8.
Sanding sheets without holes, e. g. from rolls or
by the meter, can be punctured with the perfo-
rating tool 19 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 18, unlatch the
sanding-sheet clamp 8 and pull out the sanding
sheet.
