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 wheel axles.

3. Rinse the dirt and degreaser off with a gar-
den hose. Use only enough pressure to do
the job.
cC
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical
devices. Many expensive repair bills have
resulted from improper high pressure deter-
gent 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.

4. Block up the frame to raise all wheels off
the ground.
5. Tie a plastic bag over the exhaust pipe out-
let to prevent moisture from entering.
6. 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 cover.
7. 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 or more than 30°C).
NOTE:
Make any necessary repairs before storing the
machine.
