WARNING
EWB02531Gasoline is poisonous and can cause injury or
death. Handle gasoline with care. Never siphon
gasoline by mouth. If you should swallow
some gasoline or inhale a lot of gasoline vapor,
or get some gasoline in your eyes, see yourdoctor immediately. If gasoline spills on your
skin, wash with soap and water. If gasoline
spills on your clothing, change your clothes.
NOTICEECB00070Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system.Your Yamaha engine has been designed to use
regular unleaded gasoline with a research octane
number of 91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand. Use of un-
leaded fuel will extend spark plug life and reduce
maintenance costs.EBU18820Fuel cock The fuel cock supplies fuel from the tank to the car-
buretor while also filtering it.
The fuel cock lever positions are explained as fol-
lows and shown in the illustrations. Recommended fuel:
UNLEADED GASOLINE ONLY
For Europe: Regular unleaded gasoline only
with a research octane number of 91 or
higher
Fuel tank capacity:
12.0 L (3.17 US gal, 2.64 Imp.gal)
Fuel reserve amount:

EBU19761Throttle 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.EBU19814Tires Check tire pressure regularly to make sure it is at
the recommended specifications. Also check for
wear and damage.
Tire pressure
Use the low-pressure tire gauge to check and ad-
just tire pressures when the tires are cold. Tire
pressures must be equal on both sides.
WARNING! Operation of this vehicle with im-
proper tire pressure may cause severe injury
or death from loss of control or rollover. Tire
pressure below the minimum specified could
also cause the tire to dislodge from the rim un-
der severe riding conditions.
[EWB02541]
Set tire
pressures to the following specifications: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.Recommended tire pressure:
Fro nt
20.0 kPa (0.200 kgf/cm², 2.9 psi)
Rear
25.0 kPa (0.250 kgf/cm², 3.6 psi)
Minimum tire pressure:
Fro nt
17.0 kPa (0.170 kgf/cm², 2.5 psi)
Rear
22.0 kPa (0.220 kgf/cm², 3.2 psi)
Maximum tire seating pressure:
Fro nt
250 kPa (2.5 kgf/cm², 36 psi)
Rear
250 kPa (2.5 kgf/cm², 36 psi)

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. WARNING! Al-
ways open the throttle gradually. Opening
the throttle abruptly would increase the
chance of an accident. It could make the

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 that
the 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
EWB00710Make 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 steering difficult, an accessory that
limits your ability to move around on the seat, or
one that limits your view.

Use extra caution when riding an ATV with ac-
cessories. The ATV may handle differently than
it does without accessories.EBU21101Loading
WARNING
EWB00820Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and se-
curely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.Cargo or a trailer can change the stability and han-
dling of an ATV.
You must use common sense and good judgment
when carrying cargo or towing a trailer. Keep the
following points in mind:

Never exceed the weight limits shown. An over-
loaded ATV can be unstable.
Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath-
room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad-
just the load in the trailer, if necessary, to reduce
the weight on the hitch. If you are carrying cargo
and towing a trailer, include the tongue weight in
the maximum ATV load limit.MAXIMUM LOADING LIMIT

EBU21345GETTING TO KNOW YOUR ATV
This ATV is for recreation and utility use. This sec-
tion, Riding your ATV, provides general ATV riding
instructions for recreational riding. The skills and
techniques described in this section, however, are

requires special skills acquired through practice
over a period of time. Take the time to learn the ba-
sic techniques well before attempting more difficult
maneuvers.
Riding your new ATV can be a very enjoyable ac-
tivity, providing you with hours of pleasure. But it is
essential to familiarize yourself with the operation
of the ATV to achieve the skill necessary to enjoy
riding safely. Before you begin to ride, be sure you
have read this Owner’s Manual completely and un-
derstand the operation of the controls. Pay partic-
ular attention to the safety information on pages
2-1–2-4. Also read all warning and notice labels on
your ATV.RIDE WITH CARE AND GOOD JUDGMENT
Get training if you are inexperienced.
WARNING
EWB01381
Do not operate this ATV or allow anyone else
to operate it without proper instruction. The
risk of an accident is greatly increased if the
operator does not know how to operate the
ATV properly in different situations and on
different types of terrain.
Do not operate this ATV at speeds too fast
for your skills or the conditions, as this in-
creases your chances of losing control of
the ATV and an accident. Always go at a
speed that is proper for the terrain, visibility
and operating conditions, and your experi-
ence.Beginning and inexperienced operators should
regularly practice the skills and the operating tech-
niques described in this Owner’s Manual.
