LUBRICATING THE DRIVE CHAIN

The drive chain consists of many interacting
parts. If the drive chain is not maintained prop-
erly, it will wear out quickly. Therefore, the drive
chain should be serviced, especially when the
vehicle is used in dusty areas.
This vehicle has a drive chain with small rub-
ber O-rings between each side plate. Steam
cleaning, high-pressure washing, certain sol-
vents, and the use of a coarse brush can dam-
age these O-rings. Therefore, use only
kerosene to clean the drive chain. Wipe the
drive chain dry and thoroughly lubricate it with
engine oil or chain lubricant that is suitable for
O-ring chains. Do not use any other lubricants
on the drive chain since they may contain sol-
vents that could damage the O-rings.
