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.

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 8-91. _
