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 or changing the orbital
stroke rate level; the random orbit motion will be retained.
Move the power tool with moderate pressure flat on the
workpiece in a circular motion or alternately along and
across it. Do not tilt the power tool in order to avoid sanding
through the workpiece, e.g. veneers.
Switch the power tool off after completing operation.

Polishing

For polishing weathered lacquers and redressing scratches
(e.g. acrylic glass), the power tool can be fitted with an ap-
propriate polishing tool, e.g. lambswool bonnet, polishing
felt or polishing sponge (accessory).
Select a low orbital stroke rate (level 1–2) when polishing in
order to avoid heating up the surface excessively.
Apply the polish to an area slightly smaller than the area
which you intend to polish. Using the appropriate polishing
tool, work in the polish with either linear or circular move-
ments and with moderate pressure.
Do not allow the polish to dry out on the surface; this may
damage the surface. Do not expose the surface which you in-
tend to polish to direct sunlight.
Clean the polishing tool regularly to ensure good polishing
results. Wash the polishing tools with mild detergent and
warm water; do not use thinning agents.

Application Table

The figures in the table below are recommended values.
The best method for determining the best combination while
sanding or polishing is practical experimentation.

Maintenance and Service

Maintenance and Cleaning

u

Pull the plug out of the socket before carrying out any
work on the power tool.

u

To ensure safe and efficient operation, always keep
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.
