minutes in neutral position.
7. Just prior to turning off the engine, quick-
ly spray “Fogging Oil” alternately into
each carburetor or the fogging hole of

tem becomes empty and the engine
stops.

move the spark plug(s). Pour a tea-
spoonful of clean engine oil into each
cylinder. Crank several times manually.
Replace the spark plug(s).

tails, see page 53.
NOTE:
For long-term storage, fogging the engine
with oil is recommended. Contact your
Yamaha dealer for information about fogging
oil and procedures for your engine.

Battery care
WARNING
EWM00330
Battery electrolytic fluid is dangerous; it
contains sulfuric acid and therefore is
poisonous and highly caustic.
Always follow these preventive mea-
sures:
●
Avoid bodily contact with electrolytic
fluid as it can cause severe burns or
permanent eye injury.
●
Wear protective eye gear when han-
dling or working near batteries.
Antidote (EXTERNAL):
●
SKIN - Flush with water.
●
EYES - Flush with water for 15 minutes
and get immediate medical attention.
Antidote (INTERNAL):
●
Drink large quantities of water or milk
followed by milk of magnesia, beaten
egg, or vegetable oil. Get immediate
medical attention.
Batteries also generate explosive hydro-
gen gas; therefore, you should always
follow these preventive measures:
●
Charge batteries in a well-ventilated ar-
ea.
●
Keep batteries away from fire, sparks,
or open flames (for example: welding
equipment, lighted cigarettes, and so
on.)
●
DO NOT SMOKE when charging or han-
dling batteries.
