Unperforated sanding sheets, e.g. from rolls or bulk stock

Choosing the sanding sheet
Different sanding sheets are available, depending on the ma-
terial you are working with and the required surface removal
rate:
For processing all wood and wood-based ma-
terials
For pre-sanding, e.g. of rough and un-
even beams and boards
For surface sanding and levelling of
slight irregularities
For finish-sanding and fine sanding of
hardwoods
For processing paint and lacquer layers or
primers such as fillers and bodyfillers
For sanding down paint
For sanding undercoats
For final sanding of primers prior to
painting
Note: To avoid the sanding sheet tearing, only use sanding
sheets with a grit of 80 or above.
Changing the sanding plate (see figure F)
If necessary, the sanding plate (10) can be replaced.
Bosch Power Tools
Unscrew the six screws (16) completely and remove the
sanding plate (10). Fit the new sanding plate (10) and
retighten the screws.
Special Sanding Plates
You can replace the standard supplied sanding plate (10)
with one of the special sanding plates that are available as
accessories.
Special sanding plates are fitted in exactly the same way as
the standard supplied sanding plate.
Likewise, each sanding sheet is attached and removed in ex-
actly the same way as the original sanding sheet.
Elongated sanding plate, triangular, thin (see figure G)
Using the triangular, thin, elongated sanding plate (17) en-
ables you to sand difficult-to-reach places and tight spaces
such as window and door posts, grooves, or behind radiat-
ors and water pipes.
To fit the triangular, thin, elongated sanding plate (17), use
the screws designed for this purpose (19).
Elongated sanding plate, triangular (see figure H)
Using the triangular, elongated sanding plate (21) enables
you to sand edges and corners.
Fine sanding plate (without hook-and-loop backing)
(see figures A–B)
If you primarily use standard sanding sheets without hook-
and-loop backing, we recommend using the fine sanding
plate without hook-and-loop backing. The flat surface of the
fine sanding plate will help achieve optimal sanding results,
especially when carrying out fine sanding.
