EWB00164Always stop the ATV before changing from
two-wheel drive to four-wheel drive and vice
versa. The ATV handles differently in two-
wheel drive than in four-wheel drive in some
circumstances. Changing from two-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly

4handle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.
This ATV is equipped with a switch to change from
two-wheel drive to four-wheel drive and vice ver-
sa. Select the appropriate drive according to the
terrain and the conditions.

“2WD” (two-wheel drive): Power is supplied to
the rear wheels.
 “4WD” (four-wheel drive): Power is supplied to
the rear and front wheels.
To change from two-wheel drive to four-wheel
drive, stop the ATV and push the switch in to the
“4WD” position. The four-wheel-drive indicator
light “ ” comes on.
To change from four-wheel drive to two-wheel
drive, stop the ATV and push the switch in to the
“2WD” position.
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.1. On-Command four-wheel-drive switch “2WD”/“4WD”

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). To decrease the maximum engine power avail-
able and the maximum speed of the ATV, turn
the adjusting screw in direction (b). Do not
turn the adjusting screw out more than 12
mm (0.47 in) or the throttle cable could be
damaged. Always make sure the throttle lever
free play is adjusted to 3.0–5.0 mm (0.12–
0.20 in). (See page 8-36.)
WARNING! Im-
proper adjustment of the speed limiter and
throttle could cause throttle cable damage
or improper throttle operation. You could
lose control, resulting in an accident.
