a. Wipe the drive chain with a clean cloth.
b. Put the drive chain in kerosene and remove
any remaining dirt.
c. Remove the drive chain from the kerosene
and completely dry it.
CAUTION:
_
This machine has a drive chain with small
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 internal parts, and solvents will
deteriorate the O-rings. A coarse brush can
also damage the O-rings. Therefore, use
only kerosene to clean the drive chain.
Don’t soak the drive chain in kerosene for
more than ten minutes. Kerosene will dam-
age the O-rings.
