1-CLEANING AND STORAGE
A. CLEANING
Frequent, thorough cleaning of your vehicle will
not only enhance its appearance but will improve
its general performance and extend the useful life
of many components.
1. Before cleaning the vehicle:
a. Block off the end of the exhaust pipe to pre-
vent 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, ap-
ply degreaser with a paint brush. Do not ap-
ply degreaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden
hose. Use only enough pressure to do the
job.

7. Automotive type wax may be applied to all
painted and chrome plated surfaces. Avoid
combination cleaner-waxes. Many contain
abrasives which may scratch the paint or pro-
tective finish. When finished, start the engine
and let it idle for several minutes.
WARNING
Wet brakes may have reduced stopping ability,
increasing the chance of an accident. Test the
brakes after washing. Apply the brakes several
times at slow speeds to let friction dry out the
linings.

3. Remove the spark plug, pour about one ta-
blespoon of SAE 10W30 or 20W40 motor oil
in the spark plug hole and reinstall the spark
plug. Ground the spark plug wire and turn the
engine over several times to coat the cylinder
wall with oil.
4. Lubricate all control cables.
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 atmosphere,
coat all exposed metal surfaces with a light
film of oil. Do not apply oil to any rubber parts
or the seat covers.
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 excessively warm
or cold place [less than 0°C (30°F) or more
than 30°C (90°F)].NOTE:_ Make any necessary repairs before storing the ve-
hicle. _
