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


Always be sure there are no obstacles or peo-
ple behind you when you operate in reverse.
When it is safe to proceed in reverse, go slowly.


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 instal-
lation 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
instructions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.

Tires
Always use the recommended tires.
WARNING
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.
1. The tires listed below have been approved
by Yamaha Motor Co., Ltd. for this model.
Other tire combinations are not recom-
mended.(For Europe)
(For Oceania)2. The tires should be set to the recommend-
ed pressure:
Manufacturer Size Type
Front MAXXIS AT25
× 8 - 12 M911Y
Rear MAXXIS AT25
× 10 - 12 M912Y
Manufacturer Size Type
Front CHENG-SHIN AT25
× 8 - 12 C828
Rear CHENG-SHIN AT25
× 10 - 12 C828

Recommended tire pressure
Front 25 kPa (0.25 kgf/cm
2, 0.25 bar)
Rear 25 kPa (0.25 kgf/cm2, 0.25 bar)


Check and adjust tire pressures when the
tires are cold.


Tire pressures must be equal on both
sides.
3. Tire pressure below the minimum speci-
fied could cause the tire to dislodge from
the rim under severe riding conditions.
The following are minimums:
Front 22 kPa (0.22 kgf/cm
2, 0.22 bar)
Rear 22 kPa (0.22 kgf/cm2, 0.22 bar)
4. Use no more than the following pressures
when seating the tire beads.
Front 250 kPa (2.5 kgf/cm2, 2.5 bar)
Rear 250 kPa (2.5 kgf/cm2, 2.5 bar)
Higher pressures may cause the tire to
burst. Inflate the tires very slowly and
carefully. Fast inflation could cause the
tire to burst.

EBU14450
How to measure 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 pressure with tires cold. Set tire pressures to
the following specifications:ACE-03E

WARNING
_ Always use the size and type tires specified in
the Owner’s Manual for this vehicle on pages
5-21–5-23. Always maintain proper tire pres-
sure as described in the Owner’s Manual on
page 5-25. Use of improper tires on this ATV,
or operation of this ATV with improper or un-
even tire pressure, may cause loss of control,
increasing your risk of an accident. _Do not operate at speeds too fast for your
skills or the conditions.
WARNING
_ Always go at a speed that is proper for the ter-
rain, visibility and operating conditions, and
your experience. Operating this ATV at speeds
too fast for your skills or the conditions in-
creases your chances of losing control of the
ATV, which can result in an accident. _

With the engine idling, return the starter (choke) to
the closed position, shift the drive select lever into
the forward position, and then release the parking
brake. Apply the throttle slowly and smoothly. The
centrifugal clutch will engage and you will start to
accelerate. If the throttle is applied too abruptly,
the front wheels may lift off the ground resulting in
a loss of directional control. Avoid higher speeds
until you are thoroughly familiar with the operation
of your ATV.
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. Im-
proper use of the brakes can cause the tires to
lose traction, reducing control and increasing the
possibility of an accident.
