Self-generated dust extraction with dust box (see figures
C1–C4)
Place the dust box (3) onto the extraction outlet (8) until it
clicks into place.
To empty the dust box (3), pull the dust box downwards.
Before opening the dust box (3), knock the dust box against
a firm surface as shown in the figure to loosen the dust from
the filter element.
Take hold of the dust box (3) by the recessed grip, fold the
filter element (9) upwards out of the way and empty the dust
box. Use a soft brush to clean the flaps of the filter element
(9).
External dust extraction (see figure D)
Fit a dust extraction hose (10) onto the extraction outlet (8).
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.
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 and Off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To start the power tool, push the On/Off switch (2) forwards
and into the "I" position.
To switch off the power tool, push the On/Off switch (2)
backwards and into the "0" position.
Preselecting the orbital stroke rate (PSS 250 AE)
You can even preselect the orbital stroke rate during opera-
tion using the necessary orbital stroke rate preselection
thumbwheel (1).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
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.
Bosch Power Tools
The material removal rate when sanding is primarily determ-
ined by the choice of sanding sheet and the preselected or-
bital stroke rate (PSS 250 AE).
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 Servicing
Maintenance and Cleaning
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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 a
customer service centre that is authorised to repair Bosch
power tools.
