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.
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.
Auxiliary handle
The auxiliary handle (1) enables comfortable handling and
optimum power distribution, with a high sanding removal
rate in particular.
Use the screw (2) to secure the auxiliary handle (1) on the
housing.
Dust/chip extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
Bosch Power Tools
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Self-generated dust extraction with dust box
(see figures I–M)
Slide the dust box (7) onto the extraction outlet (22). Turn
the dust box in such a manner that its recesses face against
the tips on the extraction outlet and the dust box can be felt
to engage.
You can easily check the filling level of the dust box (7)
through the transparent container.
To empty the dust box (7), rotate slightly and pull it back.
Unscrew the filter element (6) and pull it out of the dust box
(7). Empty the dust box.
Gently tap the filter element (6) against a solid surface to
loosen the dust. Use a soft brush to clean the flaps of the fil-
ter element (6).
Note: In order to ensure optimum dust extraction, empty the
dust box (7) in good time and clean the filter element (6)
regularly.
When working on vertical surfaces, hold the power tool with
the dust box (7) facing downwards.
External dust extraction (see figure N)
Fit a dust extraction hose (23) onto the extraction outlet
(22). Mount the vacuum hose onto the extraction outlet (as
shown in the figure) in such a manner that the lateral open-
ings on the extraction outlet remain free. This prevents the
power tool from adhering to the workpiece during sanding
and the surface quality of the workpiece from being im-
paired.
Connect the dust extraction hose (23) to an extractor. You
will find an overview of connecting to various dust extractors
at the end of these operating instructions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
When working on vertical surfaces, hold the power tool with
the dust extraction hose facing downwards.
Operation
Starting Operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
