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.
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 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.

WARNING
Wire Brush Operations
BRUSHING PRESSURE
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come in
contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of the
brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened brush
life.
CORRECT:
Wire tips
doing the
work.
INCORRECT:
Excessive
pressure can
cause wire
breakage.
