4 pectedly. This could distract the operator and
increase the risk of losing control and causing
an accident.
WARNING
EWB00140Always ride at a slow speed when the ATV is in
differential gear lock, and allow extra time and
distance for maneuvers.
All wheels turn at the same speed when the dif-
ferential gear is locked, so it takes more effort
to turn the ATV. The effort needed to turn in-
creases with the riding speed. You may lose
control and have an accident if you cannot
make a sharp enough turn for the speed youare traveling.NOTE:
If the differential gear lock is not engaging prop-
erly, turn the handlebar back and forth to help it
engage.
Riding before the differential gear lock is proper-
ly engaged will cause the engine speed to be
limited until engagement is complete.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 31 km/h (19 mi/h). However, if conditionsrequire full engine power to be available, push
and hold the override switch to disable the differ-
ential gear lock speed limiter. (See page 4-5 for
a detailed explanation of this switch.)EBU18280Throttle lever Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.1. Throttle lever

4Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.
WARNING
EWB00250Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you need
to. This could cause an accident. Check the op-
eration of the throttle lever before you start the
engine. If the throttle does not work smoothly,
check for the cause. Correct the problem be-fore riding the ATV or consult a Yamaha dealer.EBU18321Speed limiter Your ATV was delivered with an adjustable speed
limiter. The speed limiter keeps the throttle from
fully opening, even when the throttle lever is
pushed to the maximum.
1. Loosen the locknut.
2. To increase the maximum engine power avail-
able and the maximum speed of the ATV, turn
the adjusting screw in direction (a). To de-
crease the maximum engine power available
and the maximum speed of the ATV, turn the
adjusting screw in direction (b).3. Tighten the locknut.
WARNING
EWB00240Improper adjustment of the speed limiter and
throttle could cause throttle cable damage or
improper throttle operation. You could lose
control, have an accident or be injured. Do not
turn the adjusting screw out more than 12 mm
(0.47 in) or the throttle cable could be dam-
aged. Always make sure the throttle lever free
play is adjusted to 3.0–5.0 mm (0.12–0.20 in).(See page 8-26.)1. Locknut

EBU18460Parking brake Use the parking brake before starting the engine or
parking the ATV, especially on a slope. Apply the
rear brake lever and push down the lock plate to
apply the parking brake. Squeeze the rear brake
lever to release the parking brake.
WARNING
EWB00220
Always set the parking brake before starting
the engine. The ATV could start moving un-
expectedly if the parking brake is not ap-
plied. This could cause loss of control or a
collision.

Always be sure you have released the park-
ing brake before you begin to ride. The brake
could overheat if you ride the ATV without re-
leasing the parking brake. You could lose
braking performance which could cause an
accident. You could also wear out the brakesprematurely.EBU18581Drive select lever The drive select lever is used to shift your ATV into
the forward, neutral and reverse positions. See the
“Operating the drive select lever and driving in re-
verse” section on page 6-3 for the drive select lever
operation.

NOTE:If knocking or pinging occurs, use a different brandof gasoline or higher octane grade.CAUTION:ECB00070Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and pistonrings, as well as to the exhaust system.
WARNING
EWB00310
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.
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.
OFF
With the fuel cock lever in this position, fuel will not
flow. Always turn the fuel cock lever to this position
when the engine is not running.1. Arrow mark pointing to “OFF”

Turn the fuel cock lever to this position if you run
out of fuel while riding. When this occurs, refuel as
soon as possible and be sure to turn the fuel cock
lever back to “ON”!
