ROCKER "ON/OFF" SWITCH
TO TURN THE TOOL "ON" depress the
upper portion of the dust-protected switch to
the number "I" position.
TO TURN THE TOOL "OFF": depress the
lower portion of the switch to the number "0"
position (Fig. 1).
VARIABLE SPEED WITH DIAL SETTING
(Model ROS20VS only)
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.

START OF SANDING
With the workpiece firmly secured, place the
pad on the work surface, then switch the tool
on. DO NOT apply excessive pressure as this
will slow the pad action, and DO NOT start the
tool and bring it up to speed before applying to
the work; swirl marks will result in either case.
SANDING ACTION
In general, higher speeds will give the best
results. If faster removal is desired, DO NOT
APPLY PRESSURE ON THE TOOL; use a
