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.
To check the coolant temperature warning light,
shift the drive select lever into neutral, turn the key
to “ON”, and then press the start switch. If the light
does not come on, have a Yamaha dealer inspect
the electrical circuit.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.

On command four-wheel drive switch
“2WD/4WD”
To change from two-wheel drive (2WD) to four-
wheel drive (4WD), stop the ATV and set the
switch to the 4WD position.
To change from four-wheel drive (4WD) to two-
wheel drive (2WD), stop the ATV and set the
switch to the 2WD position.
WARNING
_ Always stop the ATV before changing from
2WD to 4WD or from 4WD to 2WD. The ATV
handles differently in 2WD than in 4WD in
some circumstances. Changing from 2WD to
4WD or vice-versa while moving may cause
the ATV to unexpectedly handle differently.
This could distract the operator and increase
the risk of losing control and an accident. _

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. Turning in the adjusting screw limits
the maximum engine power available and de-
creases 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 adjusting screw 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 8-85. _

Parking brake
Use the parking brake when you have to start the
engine or park the machine, 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
_

Always set the parking brake before start-
ing the engine. The ATV could start mov-
ing unexpectedly if the parking brake is not
applied. This could cause loss of control or
a collision.


Always be sure you have released the
parking brake before you begin to ride. The
brake could overheat if you ride the ATV
without releasing the parking brake. You
could lose braking performance which
could cause an accident. You could also
wear out the brakes prematurely.
