G G 4 1. On-Command differential gear lock switch "4WD"/"LOCK" Riding before the differential gear lock is properly engaged (e.g., when the indicator and indicator light are flashing) will cause the vehicle speed to be limited until engagement is complete. When the ATV is in four-wheel-drive differential gear lock, the maximum traveling speed is limited 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 differential gear lock speed limiter. (See page 4-6 for a detailed explanation of this switch.) To release the differential gear lock, stop the ATV and push the switch to the "4WD" position. TIP G When the switch is set to "LOCK", the differential gear lock indicator and indicator light will flash until the differential gear is locked. G When the indicator and indicator light are flashing, turning the handlebar back and forth will help the differential gear lock to engage. EBU18282 Throttle lever Once the engine is running, pushing the throttle lever will increase the engine speed. Regulate the speed of the ATV by varying the throttle position. Because the throttle is springloaded, the ATV will decelerate, and the engine will return to an idle any time the throttle lever is released. 4-11
