Fuel
Make sure that there is sufficient fuel in the tank.
(See page 4-7.)
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 8-10.)
EBU19710
Front and rear brakes
Brake lever and brake pedal
Check that there is no free play in the brake le-
ver. If there is free play, have a Yamaha dealer
check the brake system.
Check for correct brake pedal height. (See
page 8-26.) If the pedal height is incorrect, have
a Yamaha dealer adjust it.
Check the operation of the lever and pedal. They
should move smoothly and there should be a
firm feeling when the brakes are applied. If not,
have a Yamaha dealer check the brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary.
(See page 8-23.)
Brake fluid leakage
Check to see if any brake fluid is leaking out of the
pipe joints or brake fluid reservoirs. Apply the
brakes firmly for one minute. If there is any leak-
age, have a Yamaha dealer check the brake sys-Recommended brake fluid:

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 brake pads for wear. (See page 8-22.)
WARNING
EWB00580
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
a Yamaha dealer check for the cause.
EBU19761
Throttle lever
Check the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.
EBU19770
Drive chain
Check the condition of the drive chain and checkthe drive chain slack. Lubricate and adjust the
drive chain as necessary. (See page 8-30.)
EBU19791
Tires
WARNING
EWB00601
Use of improper tires on this ATV, or operation
of this ATV with improper or uneven tire pres-
sure, may cause loss of control, increasing
your risk of accident.
Pay attention to the following.
The tires listed below have been approved
by Yamaha Motor Co., Ltd. for this model.
Other tire combinations are not recommend-
ed.

The tires should be set to the recommended
pressure:
Recommended tire pressure:
Front:
27.5 kPa (4.0 psi) (0.275 kgf/cm
2
)
Rear:
27.5 kPa (4.0 psi) (0.275 kgf/cm
2
)
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:
24.5 kPa (3.5 psi) (0.245 kgf/cm
2
)
Rear:
24.5 kPa (3.5 psi) (0.245 kgf/cm
2
)
Use no more than the following pressures
when seating the tire beads.Maximum tire seating pressure:
Front:
250 kPa (36 psi) (2.5 kgf/cm
2
)
Rear:
250 kPa (36 psi) (2.5 kgf/cm
2
)
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.
NOTE:
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.
