Belt Drive vs. Chain Drive

This occurs when the belt is too loose. Under high pressure, the teeth of the belt will skip over the teeth of the pulley, creating a jerking sensation.
Symptom: A Squeaking or Rubbing Noise
This can be caused by a misaligned belt rubbing against the side of a pulley or the plastic guard.
