Sanding Plate Brake
An integrated sanding plate brake reduces the
stroke rate when running at no-load so that
scoring is prevented when placing the machine
onto the workpiece.
If the no-load stroke rate continuously increases
over the course of time, then the sanding plate
is damaged and must be replaced or the sanding
plate brake is worn. A worn sanding plate brake
must be replaced by an authorised after-sales
service agent for Bosch power tools.
Working Advice
Before any work on the machine itself, pull
the mains plug.
Wait until the machine has come to a stand-
still before placing it down.
Sanding Surfaces
Switch the machine on, place it with the com-
plete sanding surface on the surface to be
worked and move the machine with moderate
pressure over the workpiece.
The removal capacity and the sanding pattern
are mainly determined by the selection of the
sanding sheet, the preselected orbital stroke
rate and the applied pressure.
Only flawless sanding sheets achieve good
sanding capacity and extend the service life of
the machine.
Pay attention to apply uniform sanding pres-
sure; this increases the working life of the sand-
ing sheets.
Intensifiying the sanding pressure does not lead
to an increase of the sanding capacity, but to in-
creased wear of the machine and the sanding
sheet.
A sanding sheet that has been used for metal
should not be used for other materials.
Use only original Bosch sanding accessories.

Rough Sanding
Attach a sanding sheet with coarse grain.
Apply only light pressure to the machine so that
it runs at a higher stroke rate and high material
removal is achieved.
Fine Sanding
Attach a sanding sheet with fine grain.
By lightly varying the application pressure or
changing the orbital stroke rate, the sanding
plate stroke rate can be reduced whereby the
orbital action is maintained.
With moderate pressure, move the machine in a
circular pattern or alternately in lengthwise and
crosswise directions over the workpiece. Do not
tilt the machine to avoid sanding through the
workpiece (e.g. when sanding veneer).
After finishing the working procedure, switch
the power tool off.
Polishing
For the polishing of weathered paint or buffing
out scratches (e.g., acrylic glass), the machine
can be equipped with appropriate polishing ac-
cessories such as lamb's wool bonnet, polishing
felt or sponge (accessories).
Select a low stroke rate (setting 1–2) for polish-
ing in order to avoid excessive heating of the
surface.
Apply the polish onto a somewhat smaller sur-
face than you intend to polish. Work the polish-
ing agent in with a suitable polishing tool apply-
ing it crosswise or with circular motion and
moderate pressure.
Do not allow the polishing agent to dry out on
the surface, otherwise the surface can become
damaged. Do not subject the surface to be pol-
ished to direct sunlight.
Clean the polishing accessories regularly to en-
sure good polishing results. Wash out polishing
accessories with a mild detergent and warm wa-
ter; do not use paint thinner.
