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