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

f

Before any work on the machine itself, pull 
the mains plug.

f

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.
