Replacing the Sanding Sheet
When attaching a new sanding sheet, remove any
dust or debris from the sanding plate 2 (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
The sanding plate 2 is fitted with Velcro backing
for quick and easy fastening of sanding sheets
with Velcro adhesion.
Before attaching the sanding sheet 4, free the
Velcro backing of the sanding plate 2 from any
debris by tapping against it in order to enable op-
timum adhesion.
Position the sanding sheet 4 flush alongside one
edge of the sanding plate 2, 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 4, grasp it at one of
the tips and pull it off from the sanding plate 2.
Sanding Sheets without Velcro Backing
(see figure A — C)
Press the release button 5 and keep it de-
pressed.
Guide the sanding sheet 4 to the stop under
the opened front clamping bracket 6 and let
go of the release button 5 again. Pay atten-
tion that the sanding sheet is clamped cen-
trally.
Press the sanding sheet clamp 3 inward and
pivot it to the stop.
Fold the sanding sheet 4 firmly around the
sanding plate. Guide the other end of the
sanding sheet 4 between the rear clamping
bracket and the red roller on the clamping
bracket 3.
Hold the sanding sheet tensely and press the
clamping bracket 3 toward the sanding plate
to lock the sanding sheet.
Bosch Power Tools
Sanding sheets without holes, e. g. from rolls or
by the meter, can be punctured with the perfo-
rating tool 13. For this, push the power tool with
the sanding sheet mounted onto the perforating
tool (see figure F).
To remove the sanding sheet 4, loosen the
clamping bracket 3 and pull out the sanding
sheet from the rear holding fixture. Press the re-
lease button 5 and completely remove the sand-
ing sheet.

ing sheets are available:
