and fine abrasives. Because the random orbit
action is so effective, it is often possible to
begin sanding with a medium grit disc and go
directly to fine finishing. To avoid uneven
results, do not skip more than one grit size
when going from coarser to finer, and do not
sand in one area for too long.
REMOVAL OF SANDER
To help prevent swirl marks when the job is
completed, gently lift the tool from the work
surface, then switch the tool off. Operating in
this manner will also prolong the switch life.
POLISHING
For most polishing, the extra-soft backing pad
will give the best results. The random orbit
sander may be fitted with an optional foam
buffing pad or polishing bonnet to polish or
remove scratches from painted or finished
surfaces, plastics, and even glass. The tool is
operated in much the same way as when
sanding, but the following points should be
observed;
Apply the compound to the surface, and use
the sponge applicator pad with light pressure
and a circular motion to remove scratches and
restore weathered finishes. Use only as much
unauthorized per so n nel may result in
misplacing of internal wires and
components which could cause serious
hazard. We recommend that all tool service
be performed by a Bosch Factory Service
Center or Autho rized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brush es be examined.
Only genuine Bosch replace ment brushes
specially designed for your tool should be
used.

compound as necessary, and clean the
sponge frequently during use.
When initial polishing is completed, wipe away
any excess compound with a soft towel, and
then polish the surface to its final finish with the
polishing bonnet. Use smooth overlapping
strokes for best results.
It is important to note that the orbit speed of
the random orbit sander is not the same as the
RPM of a standard right-angle polisher. The
random orbit action is much like a powerful
hand polishing action, and therefore does not
have the high speeds at the edge of the pad
which can burn the work surface. For this
reason, it is possible to select a higher OPM
for the random orbit sander than the
recommended RPM for a standard polisher.
Practice on a hidden area or test surface until
you have determined the tool is suitable for
your polishing application.
