See START OF SANDING on page XX.
VARIABLE SPEED WITH DIAL SETTING
Your sander is also equipped with a variable
speed dial (Fig. 1). The sander's orbital pad
speed can be preset from zero to maximum
nameplate OPM by rotating the dial in the
housing. The dial may be set on or between
any of six positions (1=low through 6=high).
The following table may be used as a general
guide for abrasive and backing pad selection,
but the best results will be obtained by sanding
a test sample of the workpiece first.
Your sander was designed to sand in small or
confined areas. Its small size and light weight
makes it ideal for overhead work.
You may grip the tool on top or around the
motor housing as shown, which was contoured
for that purpose (Fig. 11).
SELECTING SANDING DISCS
Open-coat aluminum oxide sanding discs are
recommended for most wood or metal sanding
applications, as this synthetic material cuts
quickly and wears well. Some applications,
such as plastics, glass, or stone require silicon
carbide discs, which have a very sharp cutting
edge. For best results, use Bosch sanding
and polishing accessories, which are of
superior quality and are carefully selected to
produce professional quality results with your
sander.
An alternative to standard sanding discs is to
use a SandNet™ connection pad and
SandNet™ mesh sanding discs.

Tool Tips
START OF SANDING
With the workpiece firmly secured, first place
the sander's pad on the work surface, then
switch the tool on.
DO NOT start the tool and bring it up to speed
before applying to the work
DO NOT apply excessive pressure when
switch the tool on (or at any other time)
Either method will likely create swirl marks.
Applying excessive pressure upon start-up will
also shorten the life of the switch.
SANDING ACTION
In general, higher speeds will give the best
results. If faster removal is desired, DO NOT
