Sanding sheets with hook-and-loop backing
(see figure A)
The sanding plate (5) is fitted with a hook-and-loop fasten-
ing, allowing sanding sheets with a similar backing to be se-
cured quickly and easily.

Gently lift and unhook the clamps (4).
Guide the sanding sheet (6) all the way under the opened
rear clamp (4) and firmly clamp the sanding sheet into place
by rehooking the clamp (4).
Position the sanding sheet (6) so that it fits tightly around

sheet on the power tool and push the tool down onto the
punch (see figure E).
To remove the sanding sheet (6), undo the clamps (4) and
pull out the sanding sheet.
Selecting a sanding sheet
