Selection of the Sanding Plate
The power tool can be fitted with sanding pads of various
hardnesses, depending on the application:
– Extra soft sanding pad: Suitable for polishing and sensit-
ive sanding even on curved surfaces
– Soft sanding pad: Suitable for all sanding work, universal
application
– Hard sanding pad: Suitable for heavy sanding on flat sur-
faces
Changing the Sanding Pad
Note: Replace damaged sanding pads (8) immediately.
Remove the sanding sheet or polishing tool. Unscrew the
screw (11) completely and remove the sanding pad (8). At-
tach the new sanding pad (8) and retighten the screw so that
it is finger-tight.
Note: Pads with diameters of 150 mm and 125 mm have dif-
ferent carriers. The pads can only be fitted to the right power
tool.
Note: When attaching the sanding pad, make sure that the
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.
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.
– 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
C–G)
Slide the dust box (7) onto the extraction outlet (12). 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.
Bosch Power Tools
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 H)
Fit a dust extraction hose (13) onto the extraction outlet
(12). 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 (13) to an extractor (ac-
cessory). 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.
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.
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.
Switching on/off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the power tool, press the on/off switch (4).
To lock the on/off switch (4), press and hold it while also
pushing the lock-on button (5).
To switch off the power tool, release the on/off switch (4).
If the on/off switch (4) is locked, press the switch first and
then release it.
