FAQs:

Because of different amounts of use in different geographical locations, there isn't one answer that will apply to everyone. J&D recommends to inspect the Wall Master while it is off. You'll want to look at how much of the belt is in the groove of they pulleys. If the belt fills the width of the groove, you are good to go. If the belt is riding way into the groove, or more than 1/3 of the belt is gone (not in the groove), it's time to replace the belt and inspect the spring to make sure that when the belt is replaced, there is tension. A good thing to check is that there is free movement between the pivots of the motor mount and the pivot bracket on the x-frame. If the pivot does not swing easily, you'll want to loosen the two pivot bolts until they swing freely.
