When replacing one belt the other should be inspected for wear and
replaced if worn. It is good practice to change both belts when either
is worn beyond use. Use only original equipment belts for replace-
ment. Billy Goat uses only premium quality, kevlar corded and coated
belts in your unit. Substitute belts do not meet the design and
performance requirements for your unit , and will greatly reduce
machine performance and belt life.
