When the coolant temperature reaches a spec-
ified 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.
The coolant temperature warning light circuit
can be checked according to the procedure on
page 4-7.
CAUTION:


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


Restart after making sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.

dent or collision.
1. Set the parking brake.
2. Turn the fuel cock to “ON”.

Shifting
This model has a 5-speed forward and 1-speed
reverse transmission. The transmission allows
you to control the amount of power you have
available at a given speed or for starting, accel-
erating, climbing hills, etc. To shift into neutral,
return the throttle lever to its original position,
apply the clutch and repeatedly depress the
shift pedal until it stops. When it stops, it will
be in first gear. Raise the pedal slightly to neu-
tral.
CAUTION:
1. Do not coast for long periods with the en-
gine off, and do not tow the machine a
long distance. Even in neutral position,
the transmission is only properly lubricat-
ed when the engine is running. Inade-
quate lubrication may cause damage.
2. Always use the clutch when changing
gears. The engine, transmission and driv-
etrain are not designed to withstand the
shock of forced shifting and can be dam-
aged by shifting without the clutch.

If your ATV has stalled or stopped and you be-
lieve you can continue up the hill, restart care-
fully to make sure you do not lift the front
wheels which could cause you to lose control.
If you are unable to continue up the hill, dis-
mount the ATV on the uphill side. Physically
turn the ATV around and then descend the hill.
If you start to roll backwards, DO NOT use the
rear brake to stop or try to put the ATV in gear.
The ATV could easily tip over backwards. In-
stead, dismount the ATV immediately on the
uphill side.

WHAT TO DO IF...
This section is designed to be a reference
guide only. Be sure to read each section on
riding techniques completely.
WHAT TO DO...
If your ATV doesn’t turn when you want it
to:
Bring the ATV to a stop and practice the
turning maneuvers again. Be sure you are
putting your weight on the footboard to the
outside of the turn. Position your weight
over the front wheels for better control.
(See pages 7-39 ~ 7-43.)
If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle
and/or steer to the outside of the turn. (See
pages 7-39 ~ 7-43.)
If your ATV starts to slide sideways:
Steer in the direction of the slide if you have
the room.
Applying the brakes or accelerating is not
recommended until you have corrected the
slide. (See pages 7-69 ~ 7-71.)

If your ATV can’t make it up a hill you are
trying to climb:
Turn the ATV around if you still have for-
ward speed. If not, stop, dismount on the
uphill side of the ATV and physically turn
the ATV around. If the ATV starts to slip
backwards DO NOT USE THE REAR BRAKE
- the ATV may tip over on top of you. Dis-
mount the ATV on the uphill side. (See pag-
es 7-45 ~ 7-53.)
If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to main-
tain proper balance. If the ATV starts to tip,
steer down the hill (if there are no obstacles
in your way) to regain balance. If you dis-
cover that the ATV is going to tip over, dis-
mount on the uphill side. (See pages 7-59 ~
7-61.)
