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 the snowmobile is 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. Preventive maintenance ensures that critical components of the snowmobile are inspected by your dealer at specific mileage intervals.

You and your dealer must complete the registration form included with your snowmobile and forward it to us. This completed form is necessary to ensure warranty coverage.

Protect and preserve your right to ride by joining your local trail riding clubs.

When teaching inexperienced operators to ride, set up a predetermined course for practice. Make sure they know how to drive and control the snowmobile before allowing them to make longer trips. Te ach them proper snowmobile courtesy, and enroll them in driver’s training and safety courses sponsored by local or state organizations.

INTRODUCTION

Preservation of the Environment

POLARIS is committed to supporting an environmental education campaign. We encourage state and provincial governments across the snowbelt to adopt rigorous safety training programs that encourage protection of our environment, including wildlife and vegetation.

Snowmobile clubs and other organizations are working together to protect our environment. Please support their efforts and operate your snowmobile with consideration for the protection and preservation of our environment.

Noise Level

One of the most publicized issues about snowmobiles is noise. The Society of Automotive Engineers (SAE), the standard-setting body for snowmobile development, recommends that snowmobiles conform to prescribed sound levels.

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. We do our part by manufacturing quieter machines; we ask your help to further reduce the impact of noise by operating your snowmobile safely and responsibly.

Air Pollution

POLARIS engineers continuously investigate ways to reduce emission levels of two-stroke engines. We expect our efforts to lead to the reduction of potential air pollution.

In addition to our technological research, we encourage government agencies, manufacturers, distributors, dealers, ecologists, and other interested parties to work together to develop data on environmental topics.

INTRODUCTION

Vehicle Identification Numbers

Record your snowmobile's identification numbers and key number in the spaces provided. 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

Follow the recommended maintenance program beginning on page 79 of this manual to ensure that all critical components on the snowmobile are thoroughly inspected by your dealer at specific mileage intervals.

Driving a snowmobile requires your full attention. DO NOT drink alcohol or use drugs or medications before or while driving or riding as a passenger. They will reduce your alertness and slow your reaction time.

Snowmobiles are capable of traveling at high speeds. Use extra caution to ensure operator safety. Make sure your snowmobile is in excellent operating condition at all times. 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. DO NOT MODIFY YOUR MACHINE. The snowmobile may become aerodynamically unstable at speeds higher than those for which it is designed. Loss of control may occur at higher speeds. Modifications may also create a safety hazard and lead to bodily injury.

The warranty on your entire machine is terminated if any equipment has been added, or any modifications have been made, to increase the speed or power of the snowmobile.

WARNING

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. Be alert when riding, and remain properly seated to stay clear of the track. Never hold the snowmobile up or stand behind it while warming up the track. A loose track or flying debris could cause serious injury or death. We recommend having your dealer perform all track service and alignment procedures.

Stay Clear of Engine

Never attempt adjustments with the engine running. Turn off the ignition, open the side panels or hood, make the adjustment, secure shields and guards, secure the side panels and hood, and then restart the engine to check its operation.

WARNING! Serious injury can occur if fingers or clothing contact the moving parts of an engine. Always stop the engine before attempting adjustments.

Riding Position

Operating a snowmobile requires skill and balance for proper control. Rider positions may vary with experience and the features available on some snowmobiles, but under many 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.

WARNING! Improper riding position may reduce control and could result in serious injury or death. Always ride in a position that allows for control of your vehicle.

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.

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. Such equipment may include, but is not limited to: extra clothing, a sleeping bag, a flashlight, food and water , a signaling mirror, a means of building a fire, and a two-way radio or cellular telephone.

Always carry the owner’s manual on your snowmobile. For added protection, purchase and carry the following items on your snowmobile as well:

• Spare Drive Belt • Winter Survival Kit

• Extra Set of Spark Plugs • Trail Map

•Tow Rope •First Aid Kit

• Extra Oil • Tool Kit

• Fuel Deicer

SAFETY

Operator Safety

Rider Capacity

This snowmobile is designed for a single rider only. Never carry a passenger on this snowmobile.

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. If your speed is 40 MPH (64 km/h), your snowmobile is traveling about 60 feet (18 m) per second. If you look back for only two seconds, your snowmobile will travel about 120 feet (36 m). If your speed is 60 MPH (96 km/h), your snowmobile will travel about 180 feet (55 m) in two seconds.

Traveling at night requires extra caution. Check headlight and taillight to ensure proper operation, and don’t over-drive your headlight beam. Always be able to bring your snowmobile to a stop in the distance illuminated by the headlight.

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.

Make sure the way is clear before crossing railroads and other roads and highways. The noise of your snowmobile will drown out the sound of approaching vehicles. Look ahead, behind, and to both sides before turning or crossing railroad tracks or highways. Steep embankments may also hide your view. Always leave yourself a way out.

Variances in snow depth and/or water currents may result in uneven ice thickness. You may drown if you break through the ice. Never travel on frozen bodies of water unless you have first verified that the ice is sufficiently thick to support the weight and moving force of the snowmobile, you and your cargo, together with any other vehicles in your party. Always check with local authorities and residents to confirm ice conditions and thickness over your entire route. Snowmobile operators assume all risk associated with ice conditions on frozen bodies of water.

When teaching inexperienced operators to ride, set up a predetermined course for practice. Make sure they know how to drive and control the snowmobile before allowing them to make longer trips. Teach them proper snowmobile courtesy, and enroll them in driver's training and safety courses.

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.

You don't have to be snowmobiling on a slope for an avalanche to occur. Be aware that all of the snow is connected. You may be riding on a flat slope or snow covered road, but if the snowpack above is unstable enough you can trigger an avalanche on a steeper slope above you. Always be aware of snow conditions above you as you travel in mountainous terrain.

Before riding in mountainous terrain, call or log on to your local avalanche advisory to get current weather and snow stability information.

For more information about avalanche training and avalanche conditions, contact local law enforcement in your area, or visit the American and Canadian online avalanche centers at www.avalanche.org.

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. If dif ficulty is encountered, remove ice and snow build-up that may be obstructing the steering linkage.

Driving on Slippery Surfaces

WARNING! Never attempt an abrupt change of direction when operating on

slippery surfaces. Proceed slowly and use extra caution. Driving on ice or hardpacked snow reduces steering and braking control, which may result in loss of control and serious injury or death. Slow down and use extra caution when operating on slippery surfaces.

Inadequate Snow Conditions

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 snowmobile.

NOTICE: Driving in too little snow will result in excessive wear and damage to

the slide rail, track and/or engine.

WARNING! Inadequate cooling and lubrication will lead to overheating of the slide rail and track, causing premature wear, damage and failure, which can result in serious injury. Reduce speeds and frequently drive into fresh snow to allow adequate cooling and polishing of the slide rail and track surfaces . Avoid operating for prolonged periods on ice, hard-packed surfaces or roads.

Operating in Deep Snow

If the snowmobile becomes stuck in snow, clear the running board area of snow, then step down the snow in front of the snowmobile so that when the throttle is opened, the snowmobile will be able to climb up and over the snow.

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.

WARNING! When driving on long downhill stretches, pump the brakes. Riding the brakes may cause the brake system to overheat, which may result in brake failure. Excessive or repetitive use of the brakes for high speed stops will also cause an overheated brake system. This condition may lead to a sudden loss of brakes and/or fire and may result in serious injury or death.

Driving in Hilly Terrain

WARNING! Climbing a hill or crossing the face of a slope may result in loss of

balance and snowmobile rollover, causing serious injury or death. Use caution and good judgement when driving in hilly terrain.

Use extra caution when operating in hilly terrain. If climbing a hill is unavoidable, keep your weight low and forward. If you must cross the face of a slope, keep your weight on the uphill side of the snowmobile to maintain proper balance and avoid possible roll-over.

Slow down when reaching the crest of a hill. Be prepared to react to obstacles, sharp drops or other people or vehicles that may be on the other side of the hill.

If you're unable to continue up a hill, turn the snowmobile downhill before it loses momentum. If this isn't possible, spin the track just enough to dig in to prevent it from rolling back down the hill. Stop the engine and set the parking brake (if equipped). Keeping away from the downhill side of the snowmobile, pull the rear of the snowmobile around and point the front end and skis downhill. Remount the snowmobile, restart the engine, release the parking brake, and descend the hill carefully.

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.

Intake Silencer

Do not operate the engine with the intake silencer or filter removed.

NOTICE: Damage to the engine may occur if the intake silencer or filter are

removed.

Clutches

Do not attempt to service the clutches.

All clutch service must be performed by your dealer. The clutch is a complex mechanism that rotates at high speeds. Each clutch is dynamically balanced before installation. Any tampering may disrupt this precision balancing and create an unstable condition.

Cold Weather Drive-Away

Whenever your snowmobile has been parked for a length of time, especially overnight, always make sure the skis and track are loosened from ice and snow before attempting to drive. Apply the throttle with enough authority to put the snowmobile into motion, but always operate within safety limits.

Maneuverability

While much control and maneuverability is achieved through the steering system and skis, maximum control is achieved by the shifting of your body weight. Maneuverability will change for lighter operators or snowmobiles designed to carry a load.

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.

• A snowmobile depends on the rider's body position for proper balance in executing turns, traversing hills, etc. Always start on a smooth, level area to begin building your operating experience.

• Before allowing someone else to use your snowmobile, know the extent of their operating skills. Check to see if they've taken a snowmobile safety course and have an operator's certificate. For their protection, as well as yours, make sure they take a snowmobile safety course. Everyone can benefit from the course.

• Don't “jump” your snowmobile over large drifts or similar terrain. Jumping may injure your back because of spinal compression that could occur when the snowmobile impacts the ground. The seat and suspension of your snowmobile have been designed to provide protection under normal riding conditions. Your snowmobile is not intended for this kind of use.

• Be courteous to oncoming traffic by dimming your headlights and reducing your speed.

• When traveling in a group of snowmobiles, don't tailgate (follow too closely). Leave enough distance between snowmobiles to provide ample stopping room and to provide protection from flying snow and debris. Allow even more distance when driving on slippery surfaces or when driving in darkness or other low visibility conditions. Be aware of any snowmobile traffic around your vehicle. Drive defensively to avoid accidents.

• Remove the key from the ignition when you leave the snowmobile unattended.

• When operating with a p assenger (on approved models only) reduce speed and allow extra space for steering and stopping. A passenger reduces your ability to control the vehicle.

• When operating on hard-packed snow, ice, or when crossing roads, steering and braking ability are greatly reduced. Reduce speed and allow extra space to turn or stop.

• To maintain vehicle control on ice or hard-packed surfaces, you should have a proper balance of ski carbides to track st uds. See Owner's Manual for proper use of traction products.

• Repeated stops from high speed may cause fading or sudden loss of braking ability.

• Parking brake may relax when used for long periods. Do not leave brake engaged for more than five minutes.

• Before starting engine, check throttle, brake, and steering for proper operation. Make sure hood and side panels are latched. Be seated and in position to control the vehicle.

Oil injection system: Use unmixed fuel only. Check oil level when refueling.

Accessories

POLARIS offers a wide range of accessories for your snowmobile to help make each ride more enjoyable.

Use only POLARIS parts and accessories on your POLARIS snowmobile. Use of unapproved parts and accessories may result in:

• Non-compliance with government/industry requirements

• Voiding of warranty

• Injury to self or others This applies, but is not limited to the following areas: brakes, clutches,

fuel systems, and exhaust systems. Exhaust systems are critical safety areas that must use approved POLARIS parts. Please see your POLARIS dealer for service.

FEATURES

Fuel Type Selection

Whenever using ethanol, MTBE or other forms of oxygenated gasoline, the fuel type designation setting must be changed to “Eth” in the gauge. When using the recommended 91 non-ethanol gasoline, always select the “91-non” setting.

Whenever in doubt of your fuel purchase, use the “Eth” setting as a safeguard.

Use the following procedure to change the fuel type designation in the gauge. Refer to the fuel type selection label located inside the left side panel.

1. Start the engine.

2. Lock the parking brake.

3. Press and release the SELECT button or SET switch until “FUEL” is displayed in the lower section of the gauge.

4. Press and hold the SELECT button or SET switch until the desired fuel type is displayed in the center of the screen.

FEATURES

Detonation Elimination Technology (DET)

The DET system prevents damage to the engine from detonation by going into an engine protection mode whenever the DET system is active.

When excessive detonation is detected, the check engine light will illuminate and you may notice decreased engine performance and RPM when the DET system is activated. In most cases this is temporary and the operator does not need to take any action. The engine will return to its normal performance automatically.

If severe detonation occurs, the check engine light will begin to flash steadily and the gauge indicator will read “dET” (see illustration). The engine will enter a limp home mode and RPM will be limited to 6500 RPM. The engine will remain in this mode until it is shut down and restarted.

Check Engine Light Indicates

Solid or Flickering Excessive detonation detected

Steady Flashing Severe detonation detected, RPM will be limited

FEATURES

Detonation Elimination Technology (DET)

The most likely causes of severe detonation are outlined in the troubleshooting table below.

DET Troubleshooting

Security System (Ignition Lock System)

Your snowmobile has an optional security function that can be activated by an authorized POLARIS dealer. If you have this feature activated, you can lock the ignition to prevent unauthorized use when leaving the snowmobile unattended. A locked system will limit engine speed to 3000 RPM, which prevents clutch engagement, and the snowmobile will not move when throttle is applied.

If you wish to use this system, see page 41 of the Instrument Cluster section for security system activation and operating instructions.

Cause of DET Activation Solution

Poor quality fuel Replace with higher quality fuel Incorrect ethanol/non-ethanol fuel

Suspension Adjustments

Factory settings, combined with user adjustments to the rear track shock spring (RTSS), should be all that’s necessary to provide the best riding experience for most riders. The primary adjustment for overall vehicle balance is RTSS preload. Perform this adjustment first.

Always perform shock spring preload adjustments with the weight of the vehicle removed from the shock and with the shock at full extension.

NOTICE: Never adjust spring preload to an installed length longer than the

maximum or shorter than the minimum lengths in the following chart. Damage to the suspension could result. Never exceed one inch (2.54 cm) of preload beyond the factory settings. When decreasing preload, make sure at least two turns of preload are holding the retainer against the spring.

Suspension Adjustments

Fine-Tuning Your Suspension Set-Up

The primary adjustment for overall vehicle balance is RTSS preload. Adjust the factory-set preload to the recommended setting for your weight and then test ride. Additional minor adjustments can then be made to the spring preload to adjust the feel of the vehicle. Do not exceed the minimum and maximum installed length requirements. See page 50.

For more ski lift (transfer), reduce spring preload by increasing the installed length. Rotate the spring 1-2 full turns counter-clockwise (when viewed from bottom). This will enhance maneuverability, making the snowmobile more “flickable” although it may hinder climbing performance.

For less ski lift (transfer), increase spring preload by reducing the installed length. Rotate the spring 1-2 full turns clockwise (when viewed from bottom). This will improve climbing ability and rider control.

To control the overall balance of the vehicle use the following guideline:

• More rear track shock spring preload increases ski pressure. Less preload decreases ski pressure.

• Spring preload can affect bottoming resistance. More preload means less bottoming. Less preload means a softer ride (and more bottoming). Both adjustments will affect overall balance and ski pressure.

After adjusting RTSS preload to your satisfaction, the front track shock (FTS) spring preload and independent front suspension (IFS) spring preload can also be adjusted. See page 54.

THE PERFECT FIT

Suspension Adjustments

Shock Compression Damping (RMK/ASSAULT RMK)

The primary adjustment for overall vehicle balance is RTSS preload. Perform this adjustment first. See page 50. After adjusting RTSS preload to your satisfaction, compression damping adjustments can be made to control ride quality and bottoming resistance.

800 RMK Damping

Make the adjustments in half-turn increments, then test ride.

To stop bottoming, turn the damping screw clockwise one half-turn, then test ride. Repeat the adjustment until bottoming stops and the desired ride quality is achieved.

ASSAULT RMK (optional PRO-RMK) Damping

Compression damping can be adjusted at the front suspension and at the rear track shock. Make adjustments in 2-click increments, then test ride. When adjusting the front suspension, always adjust both clickers equally.

To stop bottoming of the front or rear suspension (stiffer ride), rotate the clicker(s) clockwise two clicks (as viewed from the top of the clicker), then test ride. Repeat the adjustment until bottoming stops and the desired ride quality is achieved.

For a more plush ride at the front or rear suspension, rotate the clicker(s) counterclockwise two clicks, then test ride. Repeat the adjustment until the desired ride quality is achieved.

Independent Front Suspension and Front Track Shock Spring Preload (RMK/PRO-RMK)

Factory settings, combined with user adjustments to the rear track shock spring, should be all that’s necessary to provide the best riding experience for most riders. The primary adjustment for overall vehicle balance is RTSS preload. Perform this adjustment first. See page 50.

After adjusting the preload, and if desired, additional adjustments can be made to the independent front suspension and front track shock preload. When adjusting the front suspension, be sure the springs on both sides of the vehicle are at the same adjustment.

Always perform shock spring preload adjustments with the weight of the vehicle removed from the shock and with the shock at full extension.

NOTICE: Never exceed one inch (2.54 cm) of preload beyond the factory

settings. When decreasing preload, make sure at least two turns of preload are holding the retainer against the spring.

For a softer ride on rough, washboard surfaces, reduce fr ont track shock (FTS) spring preload by 1-2 turns.

To improve corner stability, increase front suspension (IFS) spring

preload by 1-2 turns on both sides of the vehicle.

NOTICE: IFS spring installed length must always be set at least 1/4 inch (6 mm)

less than the free length.

OPERATION

Break-In Period

Engine Break-In

Always follow these recommended break-in procedures for new or rebuilt engines. The first tank of fuel is considered the break-in period for the engine.

Premix the first tank of fuel and fill the oil reservoir as outlined below. Oil added to the fuel and oil injection systems will provide the necessary engine lubrication.

See page 120 for the part numbers of POLARIS products. 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.

Initial Fuel Premix

Always premix fuel in 5-gallon (19-liter) increments in a separate fuel container. Never add oil directly to the fuel tank.

Oil Recommendations

First Tank of Fuel: POLARIS VES 2-Cycle Oil After Brea k-in: POLARIS VES 2-Cycle Oil

Fuel VES 2-Cycle Oil Ratio

Each 5 gal. (19 l) 16 oz. (473 ml) 40:1

OPERATION

Break-In Period

Engine Break-In

Excessive heat build-up during the first three hours of operation will damage close-fitted engine parts. Do not operate at full throttle or high speeds for extended periods during the first three hours of use. Vary the throttle openings and vehicle speeds to reduce friction on all closefitting machined parts, allowing them to break in slowly without damage.

NOTICE: Use of any lubricants other than those recommended by POLARIS

may cause serious engine damage. We recommend the use of POLARIS lubricants for your vehicle.

Drive with extra caution during the break-in period. Perform regular checks on fluid levels, lines, and all other important areas of the snowmobile.

Oil Injection System

Always check and fill the oil bottle when refueling. See page 71.

NOTICE: Serious engine damage can occur without the proper lubrication.

Check the oil bottle level often during the first tank of fuel. If the oil level doesn't go down, contact your dealer immediately.

OPERATION

Break-In Period

Drive Belt/QUICKDRIVE Belt Break-In

The length of the break-in period varies depending on the type of drive system. The break-in period for a new drive belt is 30 miles (48 km). The break-in period for a new QUICKDRIVE belt is 100 miles (160 km).

• Vary the throttle position and limit full throttle use.

• Always take time to warm up the belt and driveline prior to operating

the snowmobile. Free the track and skis from the ground before engaging throttle.

Break-In Requirements Specific to the QUICKDRIVE Belt

• During the 100 miles (160 km) of belt break-in, the rider will hear a

sound made by the drive system. After the break-in period, the sound will become similar to that of a traditional chaincase.

• Improper track tension can result in track ratcheting, which will affect

QUICKDRIVE belt durability . Always maintain proper track tension. See page 104.

• During the break-in period, this belt sheds a fiber-type material in and

around the drive system. Use a dry shop towel to clean the residue.

• Stop occasionally and allow the snowmobile to cool after high

throttle/high track load events. This will help the QUICKDRIVE belt achieve maximum performance and it will also break in the engine, drive belt and sprockets properly.

• On-trail break-in should be performed at speeds no more than 50

MPH (80 km/h).

• Always be cautious when jumping and landing a snowmobile. Avoid

“power-on” landings. Damage caused to any component due to improper use or abuse is not covered by warranty.

OPERATION

Track Warm-Up

WARNING! A loose track or flying debris could cause serious injury or death.

Stand clear of the front of the snowmobile and the moving track. Never hold the snowmobile up or stand behind it while warming up the track. Do not use excessive throttle during warm-up or when the track is free-hanging. Use a stable rear support.

WARNING! Use of traction products such as studs, ice growsers, etc. will increase the possibility of track damage and/or failure. This could cause loss of control, resulting in serious injury or death. Always inspect for track damage before operating the snowmobile.

Follow these steps to ensure proper warm-up of the engine, drive train and track.

1. Use an appropriate stand to securely support the rear of the

snowmobile at the rear bumper. The track should be about 4 inches (10 cm) off the ground.

2. Start the engine and allow it to warm up two to three minutes.

3. Depress the throttle abruptly and allow the track to rotate several

revolutions.

TIP:It will take longer to warm up the track sufficiently during colder outdoor

temperatures.

4. Release the throttle, apply the brakes, shut off the engine and lower

the snowmobile to the ground.

5. Grasp the skis by their front loops and move them from side to side

to loosen snow and ice.

Slide Rail and Track Cooling

NOTICE: Inadequate cooling and lubrication will lead to overheating of the slide

rail and track, resulting in premature wear and failure. Reduce speeds and frequently drive into fresh snow to allow adequate cooling and polishing of the slide rail and track surfaces. Avoid operating on ice, hard-packed surfaces or roads.

OPERATION

Fuel

Gasoline is highly flammable and explosive under certain conditions.

• Always exercise extreme caution whenever handling gasoline.

• Always refuel outdoors or in a well-ventilated area.

• Always tu rn off the engine before refueling.

• Do not overfill the tank. Do not fill the tank neck.

• Do not smoke or allow open flames or sparks in or near the area where

refueling is performed or where gasoline is stored.

• If gasoline spills on your skin or clothing, immediately wash it off with soap

Spark Plug Inspection

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.

CAUTION! A hot exhaust system and engine can cause burns. Wear protective gloves when removing a spark plug for inspection.

1. Remove the left side panel.

2. Remove the spark plug cap.

3. Using the special wrench provided in the tool pouch, rotate the

spark plug counter-clockwise to remove.

4. Reverse the procedure for spark plug installation. Torque to

specification.

5. Reinstall the spark plug cap.

Spark Plug Condition

Normal Plug

The normal insulator tip is gray, tan or light brown. There will be few combustion deposits. The electrodes are not burned or eroded. This indicates the proper type and heat range for the engine and the service.

TIP:The tip should not be white. A white insulator tip indicates overheating,

caused by use of an improper spark plug or incorrect carburetor/throttle body adjustments.

Wet Fouled Plug

The wet fouled insulator tip is black. A damp oil film covers the firing end. There may be a carbon layer over the entire nose. Generally, the electrodes are not worn. General causes of fouling are excessive oil or use of non-recommended injection oil.

MAINTENANCE

Oil Lines

Inspect oil line condition every 1000 miles (1600 km) as outlined in the maintenance charts beginning on page 79.

Oil Filter

Please see your dealer for replacement of the in-line oil filter every 2000 miles (3200 km) as outlined in the maintenance charts beginning on page 79.

Intake Filters

The intake foam filters limit snow ingestion into the intake system. When operating in loose powder snow, check the foam filters periodically to remove any accumulation of snow.

Fuel Pump

All fuel pump service must be performed by an authorized POLARIS dealer. Do not attempt to service the fuel pump.

Fuel Filter/Fuel Lines

See your POLARIS dealer for replacement of the fuel filter at the intervals outlined in the Periodic Maintenance Table beginning on page

80.

Contaminated or poor quality fuel will shorten the life of the fuel filter and result in poor engine performance. Always store fuel in clean fuel containers. If low fuel pressure or reduced engine performance occurs between the recommended fuel filter service intervals, the filter may need replacement. See your dealer.

Inspect the fuel lines regularly for signs of deterioration or damage. Always check fuel line condition after periods of storage. Normal deterioration from weather and fuel compounds may occur. Replace worn or damaged fuel lines promptly.

Kinking the fuel lines or using a pliers or similar tools to remove fuel lines may cause damage to the lines. If a fuel line has been damaged or kinked, replace it

promptly.

MAINTENANCE

Cooling System

Coolant

The coolant supplied in the system at the factory is a 50/50 mixture of ethylene-glycol and distilled water, which will provide adequate freeze protection under most conditions. If the vehicle will be stored or operated at extremely low temperatures, greater protection may be required. Please see your POLARIS dealer.

When adding or changing coolant, POLARIS recommends using POLARIS Antifreeze 60/40 Premix, which is already premixed and ready to use. Do not dilute with water. Never exceed a 60% antifreeze/ 40% water mixture. See page 120 for POLARIS products.

Never add tap water to the cooling system. Minerals cause deposits and may react adversely with the metals in the engine and cooling system.

Coolant Level

The engine coolant level is controlled by the recovery system. The recovery system components are:

• Coolant bottle/overflow tank

• Pressure cap

• Connecting hoses Always maintain the coolant level at or

slightly above the FULL COLD mark on the coolant bottle (when the engine is cold).

1. Stop the engine.

2. Open the right side panel.

3. View the coolant level in the coolant

bottle.

4. Add coolant as needed.

NOTICE: Operating the snowmobile with insufficient coolant will result in

overheating and serious engine damage. Always maintain the coolant level as recommended.

“Full Cold” Mark

MAINTENANCE

Cooling System

Engine Overheating

The over-temperature indicator on the instrument cluster will illuminate when the engine is overheating. The indicator will flash when engine temperature reaches critical levels.

Illuminated Indicator

Take action to cool the engine:

• Drive in loose snow.

• View the coolant level. Do not open the pressure cap while the engine is hot. Add coolant if the level is low.

• Stop the engine and allow it to cool down.

If you must continue to operate while the indicator light is illuminated, drive slowly and stop the engine frequently to allow it to cool down.

Flashing Indicator

If the indicator flashes, continued operation could result in serious engine damage. The system will automatically reduce engine power and create a misfire condition. Stop the engine immediately. Allow the engine to cool down.

If engine overheating seems to be caused by something other than poor cooling conditions, see your dealer for service.

Flushing the Cooling System

To ensure that the coolant maintains its ability to protect the engine, drain the system completely every two years and add a fresh mixture of antifreeze and distilled water. This service must be performed when the engine is cold. Ask your POLARIS dealer to check the coolant when he performs the fall tune-up on your snowmobile.

MAINTENANCE

Cooling System

Bleeding the Cooling System

CAUTION! Steam and hot liquids will cause burns to your skin. Never bleed the

cooling system or remove the pressure cap when the engine is warm or hot.

Use of a non-standard pressure cap will not allow the recovery system to function properly. If the pressure cap needs replacement, contact your dealer for the correct part.

NOTICE: If coolant flow becomes re stricted or plugged, coolant loss, air lock or

engine damage may result.

1. Position the vehicle so that the top of the tunnel is level. Elevate the

front of the vehicle slightly if necessary.

2. Make sure the engine is cold before continuing.

3. Remove the right side panel.

4. Fill the coolant bottle with properly mixed coolant to the maximum

mark. Do not install the pressure cap at this time.

5. Remove the bleed screw from the water outlet manifold and/or the

thermostat housing. Allow the coolant to bleed through the system until it runs out the bleed holes. Reinstall the bleed screw into the manifold.

6. Add coolant to the coolant bottle to the maximum mark.

7. Reinstall the side panel. Always ensure that the hood and side

panels are securely in place before starting the engine.

8. Start the engine and run at a fast idle for two to three minutes.

Loosen the bleed screw occasionally to purge any trapped air.

9. Stop the engine and check the coolant bottle level. Add coolant as

needed. Reinstall the side panel.

10. Carefully and briefly touch the top of the tunnel cooler under the

seat. If the system is bled properly, the cooler will be warm to the touch. If not, repeat step 8. Lift the front of the snowmobile slightly to assist in the bleeding.

11. Remove the side panel. Reinstall the pressure cap. Reinstall the side

panel.

12. Carefully lower the front end of the snowmobile.

MAINTENANCE

Exhaust System

Check the exhaust system for wear or damage at approximately 2000 miles (3200 km). Always allow the engine and exhaust system to cool completely before inspecting.

CAUTION! Hot exhaust system parts can cause burns. Allow adequate time for the exhaust system to cool. Never perform this procedure with the engine running.

1. Open the side panels and remove the hood. See page 83.

2. Inspect the muffler and pipes for cracks or damage.

3. Check for weak or missing retaining springs or damper/support

grommets.

4. Check for loose clamps on the pipe covers.

MAINTENANCE

Drive Chain Tension (RMK/ASSAULT RMK)

Check drive chain tension weekly and before each long trip.

1. Remove the side panels.

2. Rotate the driven clutch

counter-clockwise to move all chain slack to the tensioner side. Lock the brake lever lock, or have an assistant hold the brake lever firmly.

3. Loosen the adjuster bolt jam

nut.

4. Finger tighten the adjuster bolt

until it can no longer be adjusted by hand, then back off 1/4 turn.

5. Tighten the jam nut while

holding the adjuster bolt. Torque to 21 ft. lbs. (28 Nm).

Brakes

Hydraulic Brake Inspection

Inspect the brake lever reserve before each use of the snowmobile. See page 59.

Brake pads must be replaced when the brake pad material becomes thinner than the backing plate (approximately 1/16 inch or 1.5 mm). A kit is available for replacing brake pads. See your dealer.

WARNING! Brake failure during operation can result in serious injury or death. Properly functioning brakes are vital to your safety. Be sure the brake pads do not drag on the disc and that brake lever travel is not excessive. Always replace brake pads when the brake pad material becomes thinner than the backing plate (approximately 1/16 inch or 1.5 mm).

Brake Components

1. Brake Caliper

2. Brake Disc

3. Brake Pad Material (Replace

when thickness is less than 1/16 inch or 1.5 mm).

4. Anti-rattle springs (come

with brake pad kit)

Excessive Lever Travel

Hydraulic brakes are selfadjusting, but if excessive brake pad clearance develops, bring the snowmobile to an authorized POLARIS dealer for inspection and adjustment.

TIP:The PRO RMK and RMK ASSAULT models are equipped with a lightweight

brake disc that has vent holes. These holes may cause a high-pitched sound during operation.

MAINTENANCE

Brakes

Brake Fluid

The brake fluid level can be seen through a plastic sight glass in the brake reservoir. If the fluid is sufficient, the sight glass will be black. If the sight glass is any color other than black, add brake fluid.

Replace brake fluid at least every two years with POLARIS DOT 4 high temperature brake fluid. See page 120 for the part numbers of POLARIS products.

WARNING! After opening a bottle of brake fluid, always discard any unused portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. The moisture causes the boiling temperature of the brake fluid to drop, which can lead to early brake fade and the possibility of accident or serious injury.

WARNING! Keep the master cylinder cover free of dirt and debris. The vent slits allow for diaphragm movement, and if they become plugged, movement of brake fluid below the diaphragm may be restricted, altering brake function.

NOTICE: Brake fl uid will damage labels, paint and some plastics. Always wipe

up spills immediately.

MAINTENANCE

Brakes

Bleeding the Hydraulic Brake System

Air in the hydraulic brake system will cause spongy brake lever action. Bleed the system before operating the snowmobile.

WARNING! Operating the vehicle with a spongy brake lever can result in loss of brakes, which could cause an accident and lead to serious injury or death. Never operate the vehicle with a spongy-feeling brake lever.

During the bleeding procedure, keep the brake handle as level as possible. The reservoir must be in this position to minimize the possibility of air entering the system through the reservoir vent.

1. Remove the brake master cylinder reservoir cover and gasket.

2. Fill the master cylinder reservoir to between the MIN and MAX

marks or 1/4-5/16 inch (.6-.8 cm) below the lip of the reservoir opening. Reinstall the gasket and cover.

3. Slip a rubber tube over the ball of the bleeder valve and direct the

flow of fluid into an approved container.

4. Squeeze the brake lever a full stroke. Then unscrew the bleeder

valve 3/4 of a turn to release air.

5. Close the bleeder valve and release the brake lever.

6. Repeat steps 4 and 5 until fluid flows from the bleeder valve in a

solid stream free of air bubbles.

WARNING! Overfilling the master cylinder leaves no room for fluid expansion and may cause the brakes to lock, resulting in serious injury or death. Always add brake fluid to the fill line as recommended.

7. After bleeding is complete, refill the reservoir to the proper level.

See page 95.

8. Reinstall the gasket and cover.

MAINTENANCE

Lights

When servicing a halogen lamp, avoid touching the lamp with bare fingers. Oil from your skin leaves a residue, causing a hot spot that will shorten the life of the lamp. If fingers do touch a lamp, clean it with denatured alcohol.

Headlight Lamp Replacement

1. Peel back the foam shield covering the headlight assembly.

2. Remove the wire harness connector from the back of the headlight.

3. Grasp the bulb housing and turn it counter-clockwise to remove the

bulb.

4. Apply dielectric grease to the socket and install the new bulb.

Rotate the bulb 1/4 turn clockwise to secure it.

5. Reinstall the connector to the back of the headlight.

6. Secure the foam shield.

Taillight/Brake Light Replacement

The taillight assembly is not serviceable. If the light fails to operate properly, replace the entire taillight assembly.

MAINTENANCE

Clutch System

Periodically inspect clutch sheaves for damage, wear or belt residue. To maintain optimum performance, clean with non-oil based cleaners such as isopropyl alcohol.

WARNING! If you become aware of higher than normal clutch engagement or an unusual vibration or shift pattern, see your dealer immediately. Do not operate the snowmobile until repairs have been made.

All clutch maintenance and repairs must be performed by an authorized POLARIS dealer. Any unauthorized modifications to clutches, such as adding or removing weights, will void the warranty.

NOTICE: The bushings in the weights and rollers of POLARIS clutches are

made of a material that may be damaged if lubricated. Do not lubricate clutch bushings.

Clutch Alignment Offset

Clutch alignment offset is important for maintaining optimum performance. See your dealer for service and adjustments. A special tool is required to check for proper alignment.
