When vacuuming dry dust that is especially det-
rimental 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 9 (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 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 19, free the
Velcro backing of the sanding plate 9 from any
debris by tapping against it in order to enable
optimum adhesion.
Position the sanding sheet 19 flush alongside
one edge of the sanding plate 9, then lay the
sanding sheet onto the sanding plate and press
firmly.
To remove the sanding sheet 19, 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 19 under the opened
rear clamping bracket 10 to the stop and clamp
the sanding sheet by reinserting the sanding-
sheet clamp 8.
Fold the sanding sheet 19 firmly around the
sanding plate. Guide the other end of the sand-
ing sheet 19 under the open front clamping
bracket 10 and clamp the sanding sheet by rein-
serting 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 20 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 19, unlatch the
sanding-sheet clamp 8 and pull out the sanding
sheet.
