CLEANING AND STORAGE
A. CLEANING
Frequent, thorough cleaning of your machine
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.
1. Before cleaning the machine:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plug and all filler caps
are properly installed.
2. If the engine case is excessively greasy,
apply degreaser with a paint brush. Do
not apply degreaser to the chain, sprock-
ets or wheel axles.
3. Rinse the dirt and degreaser off with a
garden hose. Use only enough pressure
to do the job.

Yuki_DATA2:HM00G210_YFM660R-60:YFM350-9.frameEL
CAUTION:
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical de-
vices. Many expensive repair bills have result-
ed from improper high pressure detergent
applications such as those available in coin-
operated car washers.
4. Once the majority of the dirt has been
hosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.
5. Rinse the machine off immediately with
clean water and dry all surfaces with a
chamois, clean towel or soft absorbent
cloth.
6. Dry the chain and lubricate it to prevent
rust.
7. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.

5. Block up the frame to raise all wheels off
the ground.
6. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from entering.
7. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat cover.
8. Remove the battery and charge it. Store it
in a dry place and recharge it once a
month. Do not store the battery in an ex-
cessively warm or cold place (less than
0 ˚C or more than 30 ˚C).
NOTE:
Make any necessary repairs before storing the
machine.
