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, flick the on/off switch (1) to
position "I".
To switch off the power tool, flick the on/off switch (1) to
position "0".
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.
Sanding Surfaces
Switch the power tool on, place the entire sanding surface
against the surface of the workpiece and apply moderate
pressure as you move the sander over the workpiece.
The material removal rate and the sanding result are primar-
ily determined by the choice of sanding sheet and the con-
tact 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.
Rough Sanding
Attach a coarse grit sanding sheet.
Apply only light pressure to the power tool so that it runs at a
higher orbital stroke rate and a higher material removal rate
is achieved.
Fine Sanding
Attach a fine grit sanding sheet.
You can reduce the sanding plate orbital stroke rate by
lightly varying the contact pressure; the random orbit motion
will be retained.
Applying moderate pressure, move the power tool over the
surface of the workpiece, either in a circular motion or al-

ternating between crossways and lengthways. To avoid
sanding through the workpiece, e.g. veneers, do not tilt the
power tool.
Switch the power tool off once you have finished your work.

Maintenance and Service

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 an
after-sales service centre that is authorised to repair Bosch
power tools.
