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.
WARNING
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 tool down. If faster stock removal is desired, change to a
coarser grit disc.
Remove gummy paint from metal with an "open coat" disc. Sand until sparks start to appear,
then stop and change to a "closed coat" disc to remove any remaining paint.
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 sand ing 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.
Wire Brush Operations
Wire brushes are intended to "clean" structural steel, castings, sheet metal, stone and
concrete. They are used to remove rust, scale and paint.

Avoid bouncing and snagging the wire brush, especially when working
corners, sharp edges etc. This can cause loss of control and kick-back.
