CAUTION:_ Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “ENERGY CONSERVING II”)
contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.
Oil quantity:
Total amount:
2.2 L
Periodic oil change:
1.9 L
With oil filter replacement:
2.0 L

Differential gear oil
Make sure the differential gear oil is at the speci-
fied level. Add oil as necessary. (See pages 8-49 ~
8-53 for details.)
EBU00497*
Coolant
Check the coolant level in the reservoir tank when
the engine is cold. (The coolant level will vary with
engine temperature.) The coolant level is satisfac-
tory if it is between the “FULL” and “LOW” marks
on the tank. If the coolant level is at or below the
“LOW” level, add tap water (soft water) to bring the
level up to “FULL”. Change the coolant every two
years. (See pages 8-55 ~ 8-65 for details.)CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use distilled water if you can’t
get soft water. _
Recommended oil:
SAE 80 API GL-4 Hypoid gear oil

when opening. Allow any remaining pressure
to escape before completely removing the cap. _

Fittings and Fasteners
Always check the tightness of chassis fittings and
fasteners before a ride. Take the machine to a
Yamaha dealer or refer to the Service Manual for

not work smoothly, you could be unable to
control the ATV, which could lead to an acci-
dent or collision.1. Apply the rear brake lever.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the engine
stop switch to “”.
4. Shift the drive select lever into the neutral or
park position.

Pause a few seconds before the next attempt.
Each cranking should be as short as possible
to preserve battery energy. Do not crank the
engine more than 10 seconds on each at-
tempt.


If the battery is discharged, pull the recoil
starter to start the engine.

(choke) in this position to warm up the en-
gine.

Starting a warm engine
To start a warm engine, refer to the “Starting a cold
engine” section. The starter (choke) should not be
used. The throttle should be opened slightly.
EBU00182
Warming up
To get maximum engine life, always warm up the
engine before starting off. Never accelerate hard
with a cold engine! To see whether or not the en-
gine is warm, check if it responds to the throttle
normally with the starter (choke) turned off.

Shifting: Neutral to Reverse and Reverse to
ParkNOTE:The drive select lever cannot be shifted into or
from reverse or park without applying the rear
brake. 1. Bring the machine to a complete stop and re-
turn the throttle lever to the closed position.
2. Apply the rear brake pedal.
3. Shift from neutral to reverse or from reverse
to park and vice versa by moving the drive
select lever along the shift guide.NOTE:

When in reverse, the reverse indicator light
should be on. If the light does not come on,
ask a Yamaha dealer to inspect the reverse in-
dicator light electrical circuit.


Due to the synchronizing mechanism in the
engine, the light may not come on until the
ATV starts moving.
