Fuel
Make sure that there is sufficient fuel in the tank.
(See page 4-6.)
WARNING

EWB00520

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is overfilled,
fuel could spill out due to heat from the en-
gine 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 securely.
EBU19560
Engine oil
Make sure that the engine oil is at the specified lev-
el. Add oil as necessary. (See page 8-9.)
EBU19580
Transmission oil
Make sure that the transmission oil is at the speci-
fied level. Add oil as necessary. (See page 8-12.)
EBU19650
Front and rear brakes
Brake levers

Check for correct free play in the brake levers. If
the free play is incorrect, adjust it. (See pages
8-25 and 8-30.)

Check operation of the levers. They should
move smoothly and there should be a firm feel-
ing when the brake is applied. If not, have the
ATV checked by a Yamaha dealer.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance, check
the brakes for wear. (See page 8-24.)
WARNING

EWB00570
Always check the brakes at the start of every
ride. Do not ride the ATV if you find any prob-
lem with the brakes or you could lose braking
ability, which could lead to an accident. If a
problem cannot be corrected by the adjust-
ment procedures provided in this manual, have
the ATV checked by a Yamaha dealer.

The tires should be set to the recommended
pressure:
Recommended tire pressure:
Front:
20.0 kPa (0.200 kgf/cm
2
, 2.9 psi)
Rear:
25.0 kPa (0.250 kgf/cm
2
, 3.6 psi)

Check and adjust tire pressures when the
tires are cold.

Tire pressures must be equal on both
sides.

Tire pressure below the minimum speci-

fied could cause the tire to dislodge from
the rim under severe riding conditions.
Minimum tire pressure:
Front:
17.0 kPa (0.170 kgf/cm
2
, 2.5 psi)
Rear:
22.0 kPa (0.220 kgf/cm

, 36 psi)
Rear:
250 kPa (2.5 kgf/cm
2
, 36 psi)
Higher pressures and fast inflation may
cause a tire to burst. Inflate the tires very
slowly and carefully.
EBU19820
Measuring the tire pressure
Use the low-pressure tire gauge.
TIP

The low-pressure tire gauge is included as stan-
dard equipment. Make two measurements of the
tire pressure and use the second reading. Dust or
dirt in the gauge could cause the first reading to be
incorrect.
Set the tire pressure when the tires are cold. Set
the tire pressures to the following specifications:

the engine by pushing the start switch.TIP
If the engine fails to start, release the start switch,
then push it again. 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
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.NOTICE

ECB00160
For maximum engine life, always warm the en-
gine up before starting off. Never accelerate
hard when the engine is cold!
8. Continue warming up the engine until it idles
smoothly, then return the starter (choke) to
position (3) before riding.
