Working Advice
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.
Bosch Power Tools
Polishing
Note: For polishing, the extraction outlet piece
10 can be removed for easier handling of the
machine and to prevent damage to the work-
piece.
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 polishing agent crosswise or in a circular
motion with a polishing sponge and moderate
pressure, and then allow it to dry lightly.
Polish the partially dried polishing agent with
crosswise or circular motions using a lamb's
wool polishing bonnet.
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.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
When changing the sanding plate, check the
sealing collar 4 for damage. Have a damaged
sealing collar replaced by your Bosch after-sales
service agent.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
