Coolant temperature warning light “”
When the coolant temperature reaches a specified
level, this light comes on to warn that the coolant
temperature is too hot. If the light comes on during
operation, stop the engine as soon as it is safe to
do so and allow the engine to cool down for about
10 minutes.CAUTION:_

The engine may overheat if the ATV is
overloaded. If this happens, reduce the
load to specification.


After restarting, make sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.

The fuel gauge indicates the amount of fuel in the
fuel tank. The display segments of the fuel gauge
disappear towards “E” (Empty) as the fuel level de-
creases. When the “E” segment disappears and
the fuel level warning indicator flashes, set the fuel
cock to reserve and refuel as soon as possible.

On-command four-wheel drive and differential
gear lock switches
This ATV is equipped with an on-command four-
wheel drive switch “2WD”/“4WD” and a differential
gear lock switch “4WD”/“LOCK”. Select the appro-
priate drive according to terrain and the conditions.

Two-wheel drive (2WD): Power is supplied to
the rear wheels only.


Four-wheel drive (4WD): Power is supplied to
the rear and front wheels.


Four-wheel drive with the differential gear
locked (4WD-LOCK): Power is supplied to the
rear and front wheels when the differential gear
is locked (“DIFF.LOCK”). Unlike the 4WD
mode, all wheels turn at the same speed.WARNING
_ Always stop the ATV before changing from 2WD
to 4WD, or from 4WD to 4WD-LOCK, or vice-ver-
sa.
The ATV handles differently in 2WD than in 4WD
and in 4WD-LOCK in some circumstances.
Changing from 2WD to 4WD, or from 4WD to
4WD-LOCK, or vice-versa while moving may
cause the ATV to unexpectedly handle different-
ly. This could distract the operator and increase
the risk of losing control and an accident. _

WARNING
_ Always ride at a slow speed when the ATV is in
4WD-LOCK, and allow extra time and distance
for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The amount of effort is more the
faster you go. You may lose control and have
an accident if you cannot make a sharp
enough turn for the speed you are traveling. _ NOTE:_

When the switch is set to “LOCK”, the differ-
ential gear lock indicator light will flash until
the differential gear is locked.


When the indicator light is flashing, turning
the handlebar back and forth will help the dif-
ferential gear lock to engage.


Riding before the differential gear lock is
properly engaged (e.g., when the indicator
light is flashing) will cause the engine speed
to be limited until engagement is complete.


When the ATV is in 4WD-LOCK, the maxi-
mum traveling speed is limited to 35 km/h.

EBU00063
Throttle lever
Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying the
throttle position. Because the throttle is spring-
loaded, the machine will decelerate, and the en-
gine will return to an idle any time the hand is re-
moved from the throttle lever.
Before 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
Malfunction 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
operation of the throttle lever before you start
the engine. If the throttle does not work
smoothly, check for the cause. Correct the
problem before riding the ATV or consult a
Yamaha dealer.

Speed limiter
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Screwing in the adjuster limits the
maximum engine power available and decreases
the maximum speed of the ATV.
WARNING
Improper 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 speed adjuster out more than 12 mm
or the throttle cable could be damaged. Always
make sure the throttle lever free play is adjust-
ed to 3 ~ 5 mm. See page 8-89.

Recoil starter
Firmly grasp the handle and pull slightly until en-
gagement can be felt. Then pull forcefully, being
careful not to pull the rope all the way out.
WARNING

position before starting the engine, otherwise
the ATV could start to move unexpectedly,
which could cause an accident. _

WARNING
Always inspect your ATV each time you use it to make sure the ATV is in safe operating condition.
Always follow the inspection and maintenance procedures and schedules described in the Own-

4. 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 per-
formance, inspect the brake pads for wear.
(See page 8-91.)
WARNING
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 the ATV inspected by a Yamaha dealer.
