NOTICE
This vehicle has a drive chain with small
G
rubber O-rings "1" between the drive chain
side plates. Never use high-pressure water
or air, steam, gasoline, certain solvents
(e.g., benzine), or a coarse brush to clean
the drive chain. High-pressure methods
could force dirt or water into the drive
chain's internals, and solvents will deterio-
rate the O-rings. A coarse brush can also
damage the O-rings. Therefore, use only
kerosene to clean the drive chain.
Do not soak the drive chain in kerosene for
G
more than ten minutes, otherwise the
O-rings can be damaged.
