not use belt dressing on the drive belt. Belt dressing causes the
breakdown of the composition of the drive belt. Failure to follow
this recommendation will damage the drive belt.
DEFINITION: You can repair most fluid leaks by first, visually
locating the leak, repairing or replacing the component, or by
resealing the gasket surface. Once the leak is identified,
