WARNING


Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.


Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up
any spilled fuel immediately.


Do not refuel right after the engine has
been running and is still very hot.


Be sure the fuel tank cap is closed secure-
ly.

CAUTION:
Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”) con-
tain 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:
2.3 L
With oil filter cartridge replacement:
1.95 L
Periodic oil change:

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 satisfactory 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 8-31 ~ 8-39 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.
Reservoir tank capacity:
0.29 L
From “LOW” to “FULL” level:
0.165 L

WARNING
Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out un-
der pressure. Always put a thick rag over the
cap when opening. Allow any remaining pres-
sure to escape before completely removing
the cap.
EBU00498
Chain
Check the general condition of the chain and
check the chain slack before every ride. Lubri-
cate and adjust the chain as necessary. (See
pages 8-77 ~ 8-83 for details.)

Throttle lever
Check to see that the throttle lever operates
correctly. It must open smoothly and spring
back to idle position when released. Repair as
necessary for proper operation.
EBU00152
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 Man-
ual for correct tightening torque.
EBU00803
Lights
Check the headlight and tail/brake light to
make sure they are in working condition. Re-
pair as necessary for proper operation.
EBU00155
Switches
Check the operation of the headlight switch,
engine stop switch and any other switches. Re-
pair as necessary for proper operation.

Starting a cold engine
WARNING
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or do
not work smoothly, you could be unable to
control the ATV, which could lead to an acci-
dent or collision.
1. Set the parking brake.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the en-
gine stop switch to “ ”.
4. Shift the transmission into neutral.

NOTE:
This model is equipped with an ignition circuit
cut-off system. The engine can be started un-
der the following conditions.


When the transmission is in neutral. The
neutral indicator light should come on. If
the light does not come on, ask a Yamaha
dealer to inspect it.


When the clutch is disengaged with the
transmission in any position. However, it
is recommended to shift into neutral be-
fore starting the engine.
5. Use the starter (choke) in reference to the
figure:
Position
1: Cold engine start-
ambient temperature below 5 ˚C.
Position
2: Cold engine start-
ambient temperature at 0 ˚C ~
30˚C and warming up position.
Position
3: Cold engine start-
ambient temperature above
25˚C and warm engine start po-
sition.

6. Completely close the throttle lever and
start the engine by pushing the start
switch.
NOTE:
If the engine fails to start, release the start
switch, then push it again. Pause a few sec-
onds before the next attempt. Each cranking
should be as short as possible to preserve bat-
tery energy. Do not crank the engine more than
10 seconds on each attempt.
7. If the engine is started with the starter
(choke) in position
1, the starter (choke)
should be returned to position
2 to warm
up the engine. If the engine is started with
the starter (choke) in position
2, keep the
starter (choke) in this position to warm up
the engine.
8. Continue warming up the engine until it
idles smoothly and return the starter
(choke) to position
3 before riding.
CAUTION:
See the “Engine break-in” section prior to op-
erating engine for the first time.

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.
EBU00538
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 engine is warm, check if it responds to the
throttle normally with the starter (choke)
turned off.
NOTE:
When the parking brake is used, engine speed
is limited to 2,300 r/min. Be sure the parking
brake is released before moving the throttle le-
ver. Otherwise, the engine will misfire, pre-
venting normal operation.
