SANDING TIPS

For best results, tilt the Disc Sander at a 10°
to 15° angle while sanding so that only about
1" of the surface around the edge of the disc
contacts the work.
If the disc (accessory) is held flat or the back
edge of the disc comes in contact with the
work, a violent thrust to the side may result.
If sander is tilted too much, sanding action
will be too great and a rough cut surface or
gouging and snagging will result.
Guide the Disc Sander with crosswise
strokes. Be careful not to hold the sander in
one spot too long. Do not use a circular
motion, as this makes swirl marks. Test
before use on scrap stock.
Do not force or apply pressure when
sanding. Use only the weight of the tool for
pressure. Excess pressure actually slows the

change to a coarser grit disc.

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.
SANDING METAL
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.
