Sanding
Sanding discs range in grit from 16 (very course)
to 180 (very fine). They also vary in size and
spacing of grit.
OPEN COAT (type H) is used for soft materials
and on paint and varnish, CLOSED COAT (type
K) is used for metal, hardwood, stone, marble
and other materials. To obtain best results, se-
lect sanding discs carefully. Many jobs require
the use of several grit sizes and at times both
open coat and closed coat discs are required
to complete the job. See chart for application
examples.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work sur-
face, allowing the tool to operate at high
speed. Sanding rate is greatest when the
tool operates at high speed.
3. Maintain a 10° to 15° angle between the tool
and work surface, (Fig. 28).
To remove paint and to smooth surface irregularities.
To smooth the rough sanding.
To remove scratches left by previous discs.
To smooth surfaces for painting, polishing or waxing.

Operating Instructions
page heading
Operation: Refinishing painted wood or metal surfaces.
REMARKS
Fig. 28
If the disc (accessory) is
held flat or the back edge of
the disc comes in contact with the work, a vio-
lent thrust to the side may result.
4. Continuously move the tool at a moderate
speed to avoid creating gouges in the work
surface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotat-
ing before laying it down.
Tip: Guide the disc with crisscross strokes. Do
not use a circular motion as this makes swirl
marks.
