1 Examine all the teeth on the sprockets. If the teeth are “hooked” in appearance, renew the sprockets.

2 Examine the chain tensioner for wear, and renew it if necessary.

3 Examine the chain for wear. If it has been in operation for a considerable time, or if when held horizontally (rollers vertical) it takes on a deeply-bowed appearance, renew it.
