SANDING OPERATION
Make sure the switch is OFF and sander is
disconnected from the power source.
Make sure the correct sandpaper grit is
installed on the drum.
Inspect the work-piece and make sure it is
free of nails, pieces of stone or any other
foreign material which can make the
sanding operation unsafe.
See page-10 for
details.
Place the work-piece on the conveyor belt,
under the sanding drum.
Turn the height adjustment hand wheel and
lower the sanding drum until it matches the
greatest height of the work-piece. The first
pass will take off just the high spots of the
work-piece.
Remove the work-piece from the conveyor
belt and turn the sander ON.
Adjust the conveyor feed rate and stand to
the left side of the conveyor belt to avoid
any kickback.
Place the work-piece on the conveyor belt
and allow the belt to feed it under the
sanding drum.
When the work-piece is fed half way under
the sanding drum, step to the rear of the
sander and support the work-piece as it
leaves the sanding drum.
Rotate the work-piece 180° and feed the
work-piece into the sander again.
Increase the depth of cut by the correct
amount and repeat the above steps with
progressively finer grits until the desired
result is achieved.
Make sure to reduce the feed rate as the
grit and desired finish change.
Turn the switch OFF when the operation is
complete.
CONVEYOR BELT
TENSION & TRACKING
The conveyor belt tension and tracking
must be properly adjusted to ensure that
the work-piece correctly and safely passes
underneath the sanding drum.
Occasional adjustment of the conveyor feed
belt tracking may be required due to belt
stretching, normal wear and tear, and
improper tensioning. Ideally, the conveyor
feed belt should track in the center area of
the conveyor feed bet table.
If the conveyor belt slips n the rollers then
the belt tension needs to be increased.
If the conveyor belt moves to one side or
the other when it is running, then the belt
tracking needs to be adjusted.
TO TENSION THE BELT:
Disconnect the cord from the power source.
Make sure the conveyor belt is centered on
the rollers.
If not, release the belt tension equally on
both sides of the belt by holding the hex nut
with a wrench while rotating the screw
counter-clockwise until you can move the
belt from side to side with your hands. Then
center the belt on rollers. See figure-11.
