WARNING: NEVER attempt to check the belt with the engine running. Serious injuries can occur.
To service or replace the belt, first remove the top cover and check the belt tension. The belt tension is adequate if the belt is between 10 to 15 mm slack
when pressed hard with the finger between the axles.
Loose or worn belts reduce the power and efficiency of the transmission, causing poor vibration and shortening the life of the belt itself.
Belt replacement:
1. Remove the upper and lower belt covers.
2. Wrap a star key around the pulley fixing screw in order to lock it.
3. Wrap a cloth in the middle of the belt on the left side, pull it back tightly so as to remove the belt from the pulley.
Belt reinstallation:
1. Wrap the belt to lower the pulley.
2. Push the belt to the left side of the upper clutch, in the same way as for removal.
3. Turn the pulley clockwise by compensating with the star key, so that the belt comes back.
