Lubrication of driving chain
The driving chain includes many cooperating parts.They
will be worn rapidly without proper maintenance.So per-
iodical checking and repair should be conducted,which is
especially important when driving under dusty condition.
Spraying-type lubrication oil may be used. Get rid of all
dirts and mud on chain with brush or cloth. Spray the
lubricating oil onto the position between two side plates
of chain and middle roller.
When washing chain,remove the chain from the moto-
rcycle, and immerse it into solvent to clean it as far as
possible. Take out the chain from solvent and dry it.
Lubricate it quickly to avoid rust.
