    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 11

    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 12: 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.

    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 14

    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 15: 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. 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 16: Survival Preparation

    SAFETY Operator Safety Survival Preparation For your safety, always ride in a group of other snowmobilers. Always tell someone where you’re going and how long you expect to be gone. If it isn’t possible to ride with others, and you must travel into remote areas, always carry survival equipment that’s appropriate to the conditions you may encounter.

  • Page 17: Disabled Operators

    Operators with cognitive or physical disabilities have an increased risk of loss of control, which could result in serious injury or death. Rider Capacity Your Polaris snowmobile is designed for a single rider only. Do not carry a passenger. Excessive Speed WARNING High speed driving, especially at night, could result in serious injury or death.

  • Page 18: 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.

    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: Driving Downhill

    SAFETY Operator Safety Ice and Snow Build-up WARNING Ice and snow build-up may interfere with the steering of your machine, 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 21: Driving In Hilly Terrain

    SAFETY Operator Safety Driving in Hilly Terrain WARNING Climbing a hill or crossing the face of a slope may result in loss of balance and machine roll-over, causing serious injury or death. Use caution and good judgement when driving in hilly terrain. Use extra caution when operating in hilly terrain.

  • Page 22: 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 23

    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 24: 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 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.

    THE PERFECT FIT IQ Front Suspension Adjustments Break in the suspension for approximately 150 miles (240 km) before making any fine-tuning adjustments. Settings will vary from rider to rider, depending on rider weight, vehicle speed, riding style, and trail conditions. We recommend starting with factory settings and then customizing each adjustment individually to suit rider preference.

  • Page 45: Shock Absorber Components

    THE PERFECT FIT IQ Front Suspension Adjustments WARNING Always verify ski alignment before making adjustments to the IFS. See page 103 to check alignment. If the skis are misaligned, see your dealer, as the camber adjustment may also be affected. The tension at which the shock coil spring is set is called spring preload.

  • Page 46

    THE PERFECT FIT IQ Front Suspension Adjustments Shock Compression Damping (Standard Only) Adjustments to the compression stiffness of Indy Select shocks can be made by turning the adjustment screw (Select) located near the base of the shock (A). This adjustment is the easiest to perform and it should be considered first.

  • Page 47

    THE PERFECT FIT IQ Front Suspension Adjustments Front Shock Spring Preload (Premium Only) Increasing spring preload will increase ski-to-ground pressure. Decreasing spring preload will decrease ski-to-ground pressure. When adjusting, be sure the springs on both the left and right sides of the machine are at the same adjustment.

  • Page 48: Front Springs

    Shocks contain high-pressure nitrogen gas. Use extreme caution when handling high-pressure service equipment. We recommend that this work be performed by a Polaris dealer. Front Springs The front springs can be changed if spring preload alone isn’t sufficient and further adjustment is desired to control suspension stiffness.

  • Page 49: Suspension Performance Tips

    No single action on your part is as important to long, trouble-free machine life as proper break-in of a new or rebuilt engine. Premix the first tank of gasoline with one pint of Polaris injection oil for each five gallons of fuel. This, in addition to the lubrication supplied by the injection system, will assure proper engine break-in.

  • Page 64: Oil Injection System

    Never mix brands of oil. Serious chemical reactions can cause injection system blockage, resulting in serious engine damage. Oils may also be incompatible and the result could be sludge formation, filter blockage, and reduced cold weather flow rates. All Polaris oils are compatible with each other. Engine...

  • Page 83: General Maintenance

    MAINTENANCE General Maintenance Spark Plugs A new engine can cause temporary spark plug fouling due to the preservative added during the assembly process. Avoid prolonged idle speeds, which cause plug fouling and carbonization. Change the spark plugs every 2000-2500 miles (3200-4000 km). CAUTION Using non-recommended spark plugs can result in serious engine damage.

  • Page 84

    MAINTENANCE General Maintenance Spark Plugs Spark plug condition is indicative of engine operation. The spark plug firing end condition should be read after the engine has been warmed up and the vehicle has been driven at higher speeds. Immediately check the spark plug for correct color. WARNING A hot exhaust system and engine can cause serious burns.
