Fine sanding plate (without hook-and-loop backing)
(see figures A–B)
If you primarily use standard sanding sheets without hook-
and-loop backing, we recommend using the fine sanding
plate without hook-and-loop backing. The flat surface of the
fine sanding plate will help achieve optimal sanding results,
especially when carrying out fine sanding.

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 and hold 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).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
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 and sanding result are primarily
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 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.
