Avoid crossing the side of a steep hill if possible.

Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
ing, use the proper gear and maintain a steady
speed when climbing a hill. If you stall or roll
backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight up-
hill. Turn the ATV around and remount, following
the procedure described in this manual.

Always check for obstacles before operating in a
new area.

Never attempt to operate over large obstacles,
such as large rocks or fallen trees. Always follow
proper procedures when operating over obsta-
cles as described in this manual.

Always be careful when skidding or sliding.
Learn to safely control skidding or sliding by
practicing at low speeds and on level, smooth
terrain. On extremely slippery surfaces, such as
ice, go slowly and be very cautious in order to re-
duce the chance of skidding or sliding out of con-
trol.

Never operate an ATV in fast flowing water or in
water deeper than that recommended in this
manual. Remember that wet brakes may havereduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.

Always use the size and type of tires specified in
this manual.

Always maintain proper tire pressure as de-
scribed in this manual.

Never modify an ATV through improper installa-
tion or use of accessories.

Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow in-
structions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.
WARNING

EWB00061

Always turn off the engine when refueling.

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

Do not spill gasoline on the engine or ex-
haust pipe/muffler when refueling. Never re-
fuel while smoking, or in the vicinity of
sparks, open flames, or other sources of ig-
nition such as the pilot lights of water heat-
ers and clothes dryers. Gasoline can catch

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:
20 kPa (2.9 psi) (0.20 kgf/cm
2
)
Rear:
20 kPa (2.9 psi) (0.20 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:
17 kPa (2.5 psi) (0.17 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

)
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.Set the tire pressure when the tires are cold. Set
the tire pressures to the following specifications:

CAUTION:

ECB00200
Always close the throttle before shifting gears,
otherwise damage to the engine and drive train
may result.
2. Shift into first gear and release the shift pedal.
3. Open the throttle gradually.
4. Once the ATV has attained adequate speed,
release the throttle lever.
5. Shift into second gear and release the shift
pedal.
6. Open the throttle gradually.
7. Follow the same procedure when shifting to
the next higher gear.
WARNING

EWB00740
Always open the throttle gradually. Opening
the throttle abruptly would increase the chance
of an accident. It could make the ATV wheelie
or overturn.
EBU20650
To decelerate
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure thatthe engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shifting
can cause the tires to lose traction, reducing con-
trol and increasing the possibility of an accident.WARNING
EWB00710
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a low-
er gear when the engine speed is too high
could make the wheels stop rotating and lose
traction. This could cause loss of control, an
accident and injury. It could also cause engine
or drive train damage.
CAUTION:

ECB00190
Even with the transmission in the neutral posi-
tion, do not coast for long periods of time with
the engine off, and do not tow the ATV for long
distances. The transmission is properly lubri-
cated only when the engine is running. Inade-
quate lubrication may damage the
transmission.
