– 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.
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
230 V can also be operated at 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 and 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.
Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate during opera-
tion using the necessary orbital stroke rate preselection
thumbwheel (3).
1–2
Low orbital stroke rate
3–4
Medium orbital stroke rate
5–6
High orbital stroke rate
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
After working at a low orbital stoke rate for an extended
period, you should operate the power tool at the maximum
orbital stroke rate for approximately three minutes without
load to cool it down.
Sanding Plate Brake
An integrated sanding pad brake reduces the orbital stroke
rate when running without load to prevent scoring when the
power tool is placed on the workpiece.
If the no-load orbital stroke rate constantly increases over
time, this means that the sanding pad is damaged and must
be replaced, or that the sanding pad brake is worn. A worn
sanding pad brake must be replaced by an after-sales ser-
vice centre authorised to work with Bosch power tools.
Working Advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Always wait until the power tool has come to a com-
u
plete stop before placing it down.
This power tool is not suitable for bench-mounted use.
u
It must not be clamped into a vice or fastened to a work-
bench, for example.
