MAINTENANCE
CHAIN
INSPECTION
The chain must be kept clean, rust free and frequently lubricated in order to extend its life as long as
possible. It will require replacement if it stretches, breaks, or causes inefficient gear shifting. Make sure
that there are no stiff links, they must all move freely.
FREEWHEEL
INSPECTION
Like the chain, the freewheel must be kept clean
and well lubricated. If the chain has become worn
and needs replacing, then it is likely that the free-
wheel will also have become worn and should also
be replaced. Take the chain off the freewheel and
rotate it with your hand. If you hear a grinding
noise or the freewheel stops suddenly after spin-
ning it, it may need adjustment or replacement.
