Inspect Drive Belt
Visually check the drive belt for excessive wear, frayed cords, etc.
If any defect has been found, replace the drive belt.
NOTE:
- Cracks on the rib side of a belt are considered acceptable. If the missing chunks from the ribs are found on the drive belt, it should be replaced.
- After installing a drive belt, check that it fits properly in the ribbed grooves.
- Check with your hand to confirm that the drive belt has not slipped out of the groove on the bottom of the pulley.
