después de haber lavado el ATV o de haber
circulado bajo la lluvia.1. Limpie la cadena de transmisión con quero-
seno y un cepillo blando pequeño.yYPara evitar daños en las juntas tóricas, no
limpie la cadena de transmisión con limpia-

2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a
special O-ring chain lubricant.cCDo not use engine oil or any other lubricants
for the drive chain, as they may contain sub-
stances that could damage the O-rings.EBU00355Draining the V-belt compartment
If water leaks into the V-belt compartment such
as when the machine is driven in water, remove
the drain screw on the bottom of compartment
and drain the water. Be sure to drive slowly until
the V-belt becomes dry. If slipping is noticed,
ask a Yamaha dealer to inspect.

EBU00570Cable inspection and lubricationwInspect cables frequently and replace if dam-
aged. Corrosion can result when the outer
covering of control cables becomes dam-
aged. Cables can also become frayed or
kinked. Operation of controls could be
restricted, which could cause an accident or
injury.Lubricate the inner cables and the cable ends. If
the cables do not operate smoothly, ask a
Yamaha dealer to replace them.
Recommended lubricant:

wBattery electrolyte is poisonous and danger-
ous, causing severe burns, etc. It contains
sulfuric acid. Avoid contact with skin, eyes
or clothing.
Antidote:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten
egg or vegetable oil. Call a physician imme-
diately.
EYES: Flush with water for 15 minutes and
get prompt medical attention. Batteries pro-
duce explosive gases. Keep sparks, flame,
cigarettes or other sources of ignition away.
Ventilate when charging or using in an
enclosed space. Always shield your eyes

EBU00526B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive procedu-
res to guard against deterioration. After tho-
roughly cleaning the machine, prepare for stora-
ge as follows:
1. Fill the fuel tank with fresh fuel and add fuel
stabilizer (if available).NOTE:
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha dealer
if the fuel system is to be drained instead.2. Remove the spark plug, pour about one
tablespoon 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.

3. Clean the drive chain thoroughly and lubri-
cate it. (See page 8-59.)
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 out-
let 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 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 excessively
warm or cold place (less than 0°C or more
than 30°C).NOTE:
Make any necessary repairs before storing the
machine.

cCBe sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor

contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.
