Page 7: Introduction
INTRODUCTION Important Notes for Owners and Drivers After reading this manual, store it in the snowmobile for convenient reference. It should remain with the snowmobile when sold. Some of the illustrations and photos used in this manual are general representations. Your model may differ. Follow the maintenance program outlined in this manual. -
Page 8: Preservation Of The Environment
Polaris snowmobiles are engineered to conform to these SAE standards. Our muffler systems are designed to reduce noise levels and must not be altered or removed. The sound of your snowmobile may not be welcome to non-snowmobilers, so you have a responsibility to operate your snowmobile with concern for others. -
Page 9: Vehicle Identification Numbers
Remove the spare key and store it in a safe place. Your key can be duplicated only by mating a Polaris key blank with one of your existing keys, so if both keys are lost, the ignition switch must be replaced. -
Page 10: Safety
Operator Safety The following signal words and symbols appear throughout this manual and on your vehicle. Your safety is involved when these words and symbols are used. Become familiar with their meanings before reading the manual. The safety alert symbol, on your vehicle or in this manual, alerts you to the potential for injury. -
Page 11: Operator Safety
Always check major and vital safety components before every ride. All Polaris snowmobiles are designed and tested to provide safe operation when used as directed. Failure of critical machine components may result from operation with any modifications, especially those that increase speed or power. - Page 12 Operator Safety Stay Clear of Track Your snowmobile is propelled by a revolving track that must be partially exposed for proper operation. WARNING Serious injuries may result if hands, feet, or clothing become entangled in the track. Be alert when riding, and remain properly seated to stay clear of the track.
-
Page 13: Riding Position
SAFETY Operator Safety Riding Position Operating a snowmobile requires skill and balance for proper control. Rider positions may vary with experience; but under most conditions, the proper position is to be seated with both feet on the running boards and both hands on the handlebar grips for proper throttle, brake and steering control. -

Page 15: Excessive Speed
SAFETY Operator Safety Excessive Speed WARNING High speed driving, especially at night, could result in serious injury or death. Always reduce speed when driving at night or in inclement weather. Always observe all state and local laws governing snowmobile operation and speed limits. Always be alert and pay attention to the trail ahead. -
Page 16: Driver Awareness
SAFETY Operator Safety Driver Awareness Slow down when traveling near poles, posts, or other obstacles. Be especially alert if you’re snowmobiling after dark. Always be on the alert for wire fences. Single strands are especially dangerous, since there may be a great distance between posts. - Page 17 SAFETY Operator Safety Avalanches Snowmobilers should always be properly trained and equipped before traveling in mountainous terrain: S Take an avalanche class S Travel with experienced people S Travel on designated trails S Make sure each person is equipped with a shovel, probe and avalanche beacon.

Page 20: Drive Belt
SAFETY Operator Safety Drive Belt Do not operate the engine with the drive belt removed. Any servicing that requires operation without a belt must be performed by your dealer. Operation of the engine with the belt removed may result in injury or damage to the engine. Intake Silencer Do not operate the engine with the intake silencer or filter removed. -
Page 21: Inadequate Snow Conditions
SAFETY Operator Safety Inadequate Snow Conditions WARNING Do not drive for prolonged periods on blacktop, gravel, or ice. Doing so could cause irreversible track damage and lead to serious injury. Since snow provides the only lubrication for the power slide suspension and, on liquid cooled models, cooling for the engine, adequate snow cover is a requirement for operation of your machine. -
Page 22: Driving Responsibly
Operator Safety Driving Responsibly Every snowmobile handles differently, and even the most docile conditions may become dangerous if operators drive improperly. If you’re new to snowmobiling, acquaint yourself with the machine and with what it will and won’t do under various conditions. Even seasoned drivers should spend some time getting the feel for a machine before attempting ambitious maneuvers. - Page 23 SAFETY Operator Safety Windchill/Temperature Charts The following information is provided to help you determine when temperatures become dangerous for riding.
