6. when the conveyor belt is tracking in the
center of the roller brackets, run the con-
veyor for at least two minutes to ensure that
it will remain tracking correctly.
—if the tracking was not corrected by this
adjustment, repeat step 4.
—if the belt is tracking in the center of the

loosening the bolts on the outfeed bear-
ing housing (similar to the bearing housing

sure that the tracking adjustment will not
slowly change during normal operation.
2. loosen the rear adjustment nuts on both
