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 switch on the power tool, slide the on/off switch (2) for-
ward so that "I" appears on the switch.
To switch off the power tool, slide the on/off switch (2)

Preselecting the orbital stroke rate
Grit
You can even preselect the orbital stroke rate during opera-
Medium 80, 100,
tion using the necessary orbital stroke rate preselection
120
thumbwheel (1).
Fine 180, 240
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
40–320
tical tests.
Practical advice
Pull the plug out of the socket before carrying out any
u
Coarse 40, 60
work on the power tool.
Medium 80, 100,
Always wait until the power tool has come to a com-
u
120
plete stop before placing it down.
Fine 180, 240,
The material removal rate and sanding result are primarily
320
determined by the choice of sanding sheet, the preselected
orbital stroke rate level and the contact pressure.
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 Cleaning
