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).

Tool Tips

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
