5.
Do not force the belts into the pulley grooves by prying with
a screwdriver or pry bar. This will damage the belt side
cords which will cause the belts to turn and result in
complete destruction of the belts in operation.
6.
Belts on new machines and replacement belts lose their
tension as they seat into the pulley grooves. Check the
tension of new belts at 20 hour intervals until tension is
stabilized and thereafter, every 250 hours. If the tension
falls below the required minimum, the belt will be able to
slip, damaging the belts and pulley grooves.
NOTE:
When operating in abrasive conditions, check
tension every 100 hours.
