Ribbed Belt, Removing And Installing

NOTE:
- Always replace ribbed belt if found to be faulty. This will avoid related break-downs or operating problems.
- If a used ribbed belt is to be reused, mark direction of rotation before removing. When installing used ribbed belts observe the direction of rotation marked on removal. Installing opposite to the direction of rotation leads to belt damage.
- It is not necessary to adjust ribbed belt tension. A spring loaded tensioner automatically adjusts belt tension.
