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.
U8FP15E0.book Page 7 Thursday, July 23, 2009 11:01 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.
