    INTRODUCTION Important Notes for Owners and Drivers After reading this manual, store it in the snowmobile (if possible) for convenient reference. It should remain with the snowmobile when the snowmobile is sold. Some of the illustrations and photos used in this manual are general representations.

  • Page 7: 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 8: 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 9: Safety

    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 indicates a potential personal injury hazard. DANGER A DANGER indicates a hazardous situation that, if not avoided, will result in death or serious injury.

  • Page 10: 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 11: Riding Position

    SAFETY Operator Safety Stay Clear of Track Your snowmobile is propelled by a revolving track that must be partially exposed for proper operation. Do not stand on the plastic flap. WARNING! Serious injuries may result if hands, feet, or clothing become entangled in the track.

  • Page 12: Riding Apparel

    Riding Apparel Helmet Wearing a helmet can prevent a severe head injury. Whenever riding a POLARIS vehicle, always wear a helmet that meets or exceeds established safety standards. Approved helmets in the USA and Canada bear a U.S. Department of Transportation (DOT) label.

  • Page 13: Disabled Operators

    SAFETY Operator Safety Disabled Operators Safe operation of this rider-active vehicle requires good judgement and physical skills. Operators with cognitive or physical disabilities have an increased risk of loss of control, which could result in serious injury or death. Cargo Overload Too much weight on the rear of the machine may reduce your ability to steer.

  • Page 14: Rider Capacity

    Operator Safety Rider Capacity Some POLARIS snowmobiles are designed for a single rider only, while some are designed for up to two riders. A safety label on the vehicle indicates whether the vehicle is designed for a single rider or for two riders.
  • Page 15 SAFETY Operator Safety Driving With a Passenger 12. A passenger should always be seated in the passenger seat with both feet on the running boards/footrests and both hands on the passenger grab handles at all times. The passenger should never hold on to the operator.

  • 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. Guy wires on utility poles are also difficult to distinguish.

  • Page 17: 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 18 SAFETY Operator Safety Avalanches Snowmobilers should always be properly trained and equipped before traveling in mountainous terrain: • Take an avalanche class • Travel with experienced people • Travel on designated trails • Make sure each person is equipped with a shovel, probe and avalanche beacon.

  • Page 19: Inadequate Snow Conditions

    SAFETY Operator Safety Ice and Snow Build-up WARNING! Ice and snow build-up may interfere with the steering of your snowmobile, resulting in serious injury or death. Keep the underhood area free of snow and ice. Before driving, manually turn the skis to the left and right to be sure ice and snow are not interfering with full left and right steering.

  • Page 20: Driving Downhill

    SAFETY Operator Safety Driving Downhill When riding downhill, shift your weight to the rear of the snowmobile and reduce your speed to a minimum. Apply just enough throttle to keep the clutch engaged, allowing the engine's compression to help slow the snowmobile and keep it from rolling freely downhill.

  • Page 21: 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. NOTICE: Operation of the engine with the belt removed may result in injury or damage to the engine.

  • Page 22: Driving Responsibly

    SAFETY 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 snowmobile and with what it will and won't do under various conditions. Even seasoned drivers should spend some time getting the feel for a snowmobile before attempting ambitious maneuvers.
