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 bag (GSS 140
A) (see figures E–G)
Place and move the complete dust bag (8) onto the extrac-
tion outlet (9) until it lines up precisely with the power tool.
To empty the dust bag, pull the complete dust bag (8) away
from the extraction outlet (9).
Note: Empty the dust bag (8) in good time to ensure op-
timum dust extraction.
When working vertical surfaces, hold the power tool in such
a manner that the dust bag (8) faces downward.
External Dust Extraction (GSS 140 A) (see figure H)
Fit a dust extraction hose (10) onto the extraction outlet (9).
Connect the dust extraction hose (10) 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.
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, tilt the on/off switch (1) to-
ward the right to the "I" position.
To switch off the power tool, tilt the on/off switch (1) to-
ward the left to the "O" position.
Bosch Power Tools
Practical 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.
The material removal rate when sanding is primarily determ-
ined by the choice of sanding sheet.
Only immaculate sanding sheets achieve good sanding per-
formance and make the power tool last longer.
Be sure to apply consistent contact pressure in order to in-
crease the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
Do not use a sanding sheet for other materials after it has
been used to work on metal.
Use only original Bosch-sanding accessories.
Maintenance and Service
Maintenance and Cleaning
Pull the plug out of the socket before carrying out any
u

To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
