Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Changing the Sanding Sheet (see figure A)
To remove the sanding sheet (14), lift it from the side and
pull it off the intermediate pad (15).
Remove dirt and dust from the intermediate pad (15), e.g.
with a paintbrush, before attaching a new sanding sheet.
The surface of the intermediate pad (15) is fitted with a
hook-and-loop fastening, allowing sanding sheets with a
hook-and-loop backing to be secured quickly and easily.
Press the sanding sheet (14) firmly onto the underside of
the intermediate pad (15).
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet (14) are aligned with the
punched holes in the intermediate pad (15) and the drilled
holes in the sanding pad (17).
Note: An intermediate pad (15) is not required when work-
ing with the medium-hard sanding pad; the sanding
sheet (14) is attached directly to the sanding pad (17). In all
other cases, the change is performed as described here.

/I
and-loop fastening, allowing intermediate pads to be se-
cured quickly and easily.
Press the intermediate pad (15) firmly against the underside
of the sanding pad (17).
To ensure optimum dust extraction, make sure that the
punched holes in the intermediate pad (15) are aligned with
the drilled holes in the sanding pad (17).
Changing the Sanding Pad (see figure B)
Note: Replace damaged sanding pads (17) immediately.
Pull off the sanding sheet (14) and the intermediate
pad (15). Unscrew the screw (16) completely and remove
the sanding pad (17). Attach the new sanding pad (17) and

teeth of the catch mate with the recesses in the sanding pad.
Note: Damaged sanding pads must only be replaced by an
after-sales service centre authorised to work with Bosch
power tools.
Inserting/Removing the Extension Tube
(see figures C–D)
Only use the extension tubes (10) if necessary. The effort re-
quired for the sanding is significantly lower when working
without extension tubes.
Note: A maximum of two extension tubes may be inserted.

hard plaster and removing old wall
paints
