SANDING OPERATIONS
CAUTION:
To avoid personal
injury andlor
damage
to the
workpiece,
become
familiar with the rotation of the belt and
disc sanding surfaces.
The belt sander
rotates
clockwise,
or downward
toward
the table. The disc sander
also rotates
clockwise,
downward
toward the table on the right side of the disc at
all times.
Using the left side of the disc will cause the
workpiece
to fly up or kickback
and could result
in injury.
Review this instruction
manual
for correct
operation,
adjustments,
and basic sanding
operations.
Apply only
enough
pressure
to remove material;
excessive
pressure
wil! reduce
sanding
efficiency.
After sanding wood and other nommetal materials, clean
the area of sawdust and debris before grinding metal.
Sparks could ignite debris and cause a fire.
To avoid injury from slips, jams or thrown pieces, make sure
all adjustments are made. Review section "ASSEMBLY AND
ADJUSTMENTS" for correct disc adjustments.
End sanding and outside curve sanding.

workpieces and outside curved edges. Always work on
the right side of the disc center (downward rotation

pressure against the sanding disc.

The disc moves the fastest and removes more
material at the outer edge.
Using the left side (upward rotation side) of the disc will
cause the workpiece to fly up or kick back and could
result in injury.
