The conveyor belt must track straight. If the feed
belt tracks to either side, then the tracking must
be corrected or the conveyor belt will become
damaged and have to be replaced. The tracking
Motor Pulley
was properly set at the factory, but it is the respon-
sibility of the end user to keep it tracking properly
during the life of the machine.
Tracking the conveyor belt is a balancing process
that takes patience and a small degree of trial-
and-error.
You begin coarse tracking adjustment by rotating
the right conveyor belt adjustment bolt clockwise
or counterclockwise. If the belt continues to track
to one side then you must over-tighten the loose
side (the side the belt is tracking towards) to make
the conveyor belt move to the middle of the rollers,
then loosen that same side to make the feed belt
stay in position. If you adjust the tracking screw
too much either way, then you have to repeat the
process until the conveyor belt rides in the middle
and stays there during continuous operation.

Working around moving conveyor and parts
presents pinch/entanglement hazards that
can cause personal injury. Use extreme
care to keep hands clear of in-running pinch
points while adjusting tracking nut/screw
when machine is running. Roll up sleeves
and do not wear gloves or other apparel that
could become entangled in moving parts.
