EBU28510 EWB00150 Override switch "OVERRIDE" 1 WARNING Always ride at a slow speed when the ATV is in four-wheel-drive differential gear lock, and allow extra time and distance for maneuvers. All wheels turn at the same speed when the differential is locked, so it takes more effort to turn the ATV. The effort needed to turn increases with the riding speed. You may lose control and have an accident if you cannot make a sharp enough turn for the speed you are traveling. 4 1. Override switch "OVERRIDE" Top speed is normally limited when operating in differential gear lock. If conditions require more engine power when riding forward, push and hold this switch to override the differential gear lock speed limiting function. (See page 4-8.) Releasing the switch restores the speed limiting function. While the override switch is pushed, the reverse indicator light "REVERSE" will flash. 4-6
