SANDING WOOD
When sanding wood the direction of the disc
motion at the contact point should parallel the
grain as much as possible. The rapid cut of
discs and the swirl type scratch pattern they
occasionally create generally prohibit their
use for producing the final finish.
Scratches and circular marks are usually the
result of using too coarse a grit. When
changing to a finer grit, move across the
sanding lines that were made by a previous
coarser disc.
POLISHING TIPS
For the polishing of weathered paint or
buffing out scratches (e.g., acrylic glass), the
tool may be fitted with appropriate polishing
accessories such as lamb's wool bonnet,
polishing felt or sponge (optional accessories).
Select a low speed for polishing (dial setting
1 – 2) in order to avoid excessive heating of
the surface.
Apply the compound to the surface, and use
the sponge applicator pad with light pressure
and a circular motion to remove scratches and
restore weathered finishes. Use only as much

When sanding automobiles or appliances,
wipe the metal clean with a non-flammable
solvent or commercial cleaner to remove all
wax and grease. By doing this first, the
sanding discs will sand better and last longer.
For heavy duty work, use a coarse grit disc
first. Follow-up with a medium grit to remove
scratches. To produce smooth finish, use fine
grit disc.
compound as necessary, and clean the
sponge frequently during use.
When initial polishing is completed, wipe away
any excess compound with a soft towel, and
then polish the surface to its final finish with the
buffing pad. Use smooth overlapping strokes
for best results.
Clean the buffing pad and sponge applicator
pad with mild detergents and warm water. DO
NOT use solvents.
