
Riding before the differential gear is properly en-
gaged or disengaged (e.g., when the indicator
and indicator light are flashing) will cause the
vehicle speed to be limited until the differential
gear is completely engaged or disengaged.
 When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 35 km/h (22 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the dif-
ferential gear lock speed limiter. (See page 4-8
for a detailed explanation of this switch.)
EBU18283Throttle leverOnce the engine is running, pushing the throttle le-
ver will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine
will return to an idle any time the throttle lever is re-
leased. 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.
EBU18324Speed limiterYour ATV is equipped with an adjustable speed
limiter. The speed limiter keeps the throttle from
fully opening, even when the throttle lever is
pushed to the maximum.
1. Loosen the locknut.
2. To increase the maximum engine power available and the maximum speed of the ATV,
turn the adjusting screw in direction (a). To1. Throttle lever

running or with the headlights turned on, the
battery will lose its charge and engine start-
ing 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. Maximum rated capacity for the auxiliary DC
