Abrasive Sheets
Aluminum oxide, silicon carbide, or other synthetic abrasives are recommended for power
sanding use. Natural abrasives, such as flint or garnet sheet are too soft for economical use in
power sanding.
For best results, use Skil abrasive sheets: The uniform spacing between grains minimizes
filling or loading. The high quality aluminum oxide sheet with heavy backing, cuts faster and
lasts longer.
The following are recommended abrasive sheets and applications:
1. Coarse Grit: For rough wood sanding.
2. Medium Grit: For general wood sanding.
3. Fine Grit: For smoothing wood or plaster patches.
4. Extra Fine Grit: For final sanding bare wood and smoothing old paint.

This sander has been designed for even weight
distribution which virtually eliminates the use
of pressure. Excessive pressure to the sander
may result in an uneven sanding job and
premature grit wear. Constant and excessive
pressure can cause overheating and possible
damage to the motor as well as premature
wear out of the pad on hook and loop models.
It's usually best to work in strokes that parallel
the grain, using some lateral motion so the
main strokes are overlapped as much as 75%.
If the surface is rough, start sanding with
11-1/16" (280mm)
a coarse grit sheet, then medium and then
finish with a fine or extra fine abrasive. This
procedure will vary with different types of materials and work. Continue to sand with each grit
until the surface looks uniform. When going from one grit size to a finer size, do not skip more
than two sizes.
To remove the greatest amount of stock, use a coarse grit and move the sander steadily over
the entire surface against the grain as well as with the grain. DO NOT REMAIN IN ONE SPOT
TOO LONG. It may remove too much material and un even sanding will result. Sanding with
the grain of the wood gives the smoothest final finish.
Additional abrasive sheets can be conveniently cut from large-size commercially available
sheets (standard size: 9" x 11-1/16"; 228 x 280mm). Cut into four pieces of equal size as
shown (Fig. 4). Choose the proper grit for the job.
