When you ride your snowmobile, you must know and use the following for your safety. Severe injury or death may result if you ignore any of the following. ● While using your snowmobile ● Before you operate your snowmobile ● ● Read the Owner’s Manual and all labels.
U8GK13E0.book Page 7 Wednesday, March 11, 2009 10:54 AM Safety information ● Many surfaces such as ice and hardpacked snow require much longer stopping distances. Be alert, plan ahead and begin decelerating early. The best braking method on most surfaces is to release the throttle and apply the brake gently—not suddenly. Avoid carbon monoxide poisoning All engine exhaust contains carbon monoxide, a deadly gas.

Braking EWS00220 WARNING ● Learning to ride your snowmobile Before you ride, always perform the pre-operation checks listed on page 33.
U8GK13E0.book Page 38 Wednesday, March 11, 2009 10:54 AM Operation Improper riding techniques such as abrupt throttle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the snowmobile to tip. If your snowmobile begins to tip while turning, lean more into the turn to regain balance. If necessary, gradually let off on the throttle or steer to the outside of the turn.
