WARNING
Operating with improperly adjusted brakes
could cause the brakes to malfunction result-
ing in reduced braking performance. This
could increase the chance of a collision or acci-
dent. After adjusting the parking brake, block
the rear of the machine off the ground and
spin the rear wheels. Check to make sure there
is no brake drag. If brake drag is noticed, per-form the adjustment again.

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.

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.
