CHAINS
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.
Lubrication
The chain (bicycle and motor drive) should be lubricated with light oil at
least every month, or after use in wet, muddy, or dusty conditions. Take
care to wipe off excess oil, and not to get oil on the tires or rim braking
surfaces.
