Override switch “OVERRIDE”
Top speed is normally limited when operating in
4WD-LOCK. If conditions require more engine
power when riding forward, push and hold this
switch to override the 4WD-LOCK speed limiting
function. (See pages 4-31–4-33 for a detailed ex-
planation about the differential gear lock switch
and its function.) Releasing the switch restores the
speed limiting function.
While this switch is pushed, the segments of the
speedometer digits will appear as shown in the fig-
ure.NOTE:_ If the digits of the speedometer appear as shown
when the switch is NOT being pushed, this could
indicate a malfunction in the electrical system. In
this case, take the ATV to a Yamaha dealer at the
first opportunity. _

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.
However, if conditions require full engine
power to be available, push and hold the
override switch to disable the 4WD-LOCK
speed limiter. (See pages 4-21–4-23 for a de-
tailed explanation of this switch.)

1. Levier d’accélération
1. Palanca de aceleración
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 3.0–5.0 mm. See page 8-91. _

DC jack should only be used when the engine is
running.
1. Set the light switch to “OFF”.
2. Start the engine. (See pages 6-3–6-7.)
3. Open the auxiliary DC jack cap, and then in-
sert the accessory power plug into the jack.
4. When the auxiliary DC jack is not being used,

CAUTION:_

Do not use accessories requiring more
than the above maximum capacity. This
may overload the circuit and cause the
fuse to blow.


If accessories are used without the engine
running or with the headlights turned on,
the battery will lose its charge and engine
starting may become difficult.


Do not use an automotive cigarette lighter
or other accessories with a plug that gets
hot because the jack can be damaged.
