INTRODUCTION

Preservation Of The Environment

Please 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 t o 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

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 t hat 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 do your part to preserve and protect our environment.

Respect your snowmobile;

respect your environment;

and you will earn

the respect of everyone.

INTRODUCTION

Vehicle Identification Numbers

Please record your snowmobile identification numbers below for future reference:

Tunnel VIN (lower right side of the tunnel)

Engine Serial Number (right front side of engine crankcase)

Remove the spare key and store it in a safe place. Your key can be duplicated only by obtaining a key blank from Polaris and mating it with your existing key.

The VIN and engine serial numbers are necessary for model identification when registering your vehicle and obtaining insurance, or when replacement parts are required. If your snowmobile is stolen, these numbers are essential to its recovery and identification.

SAFETY

Operator Safety

WARNING

Driving a snowmobile requires your full attention. DO NOT drink alcohol or use drugs or medications before or while driving. They will reduce your alertness and slow your reaction time. In most states and provinces, it’s prohibited by law to drive while intoxicated or under the influence of drugs.

Polaris produces high performance snowmobiles capable of traveling at high speeds. Extra caution must be observed to ensure operator safety. Make sure your snowmobile is in excellent operating condition at all times. We strongly recommend that the operator 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.

SAFETY

Operator Safety

Stay Away From Moving Parts

WARNING

Never hold the snowmobile up or stand behind it while warming up the track. A loose track or flying debris could cause serious personal injury or death.

We recommend having your dealer perform track service and alignment procedures.

Be alert when riding, and remain properly seated to stay clear of the track. Your snowmobile is propelled by a revolving track that must be partially exposed for proper operation. Serious injuries may result if hands, feet, or clothing become entangled in the track.

WARNING

Stop the engine before attempting adjustments. If contact is made with fingers or clothing, the moving parts of an engine can cause serious injury.

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

SAFETY

Operator Safety

Be Seated and in Position to Control the Vehicle

WARNING

Improper riding position may seriously reduce your ability to control the machine and may result in serious injury or death. Always be properly seated and in position to control your vehicle.

Operating a snowmobile requires skill and balance for proper control. Rider positions may vary from person to person as each becomes more skilled; but under most conditions, the proper position is to be seated with feet on the running boards, and comfortably positioned for proper throttle, brake, and steering control.

WARNING

Use of a backrest may hinder your weight shifting ability. This could affect your ability to control this rider-active vehicle in certain extreme driving situations.

Be Prepared fo r the Unexpected

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 t elephone.

SAFETY

Operator Safety

Do Not Overload Cargo Carrier

Too much weight on the rear of the machine may reduce your ability to steer. Do not exceed carrier and rack weight limits, and do not allow a passenger to sit on the seat back or the cargo carrier.

WARNING

Control becomes more difficult with two people on board. More space is required to make turns, and longer distances are needed for stopping. Make sure the passenger remains seated behind the driver, facing forward, with both feet placed firmly on the running boards. Slow down and avoid “jumping” your snowmobile.

Always Wear Clothing Designed f or Snowmobiling

WARNING

Loose clothing or long scarves may easily become entangled in moving parts and cause serious personal injury .

Always wear an approved helmet and eye protection.

Be aware of the weather forecast and especially the wind chill. A table is provided on page 26 for your reference. To better enjoy your ride, be prepared, warm, and comfortable.

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 i n serious injury or death.

Know the Limitations of the Machine and Yo ur Skills as a Driver

WARNING

High speed driving, especially at night, is dangerous and unwise and could result in serious personal injury or death.

Observe all state and local laws governing snowmobile operation. They’ve been established for your protection.

Always be alert and pay attention to the trail ahead of you. Multiplying speed (MPH) by 1.5 will equal the approximate number of feet per second your machine travels. If your speed is 40 MPH, your machine is traveling about 60 feet per second. If you look back for only two seconds, your machine will travel about 120 feet. If your speed is 60 MPH, your machine will travel about 180 feet 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 machine to a stop in the distance illuminated by the headlight.

SAFETY

Operator Safety

Know the Limitations of the Machine and Yo ur Skills as a Driver

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 machine 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. Always check with local residents or authorities for general information on conditions when traveling on lakes and streams that are strange to you. Before riding your machine on a frozen body of water, be sure the ice is thick enough to support the machine and its operator, as well as the force created by a moving vehicle. You may drown if you and the snowmobile break through the ice.

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 sponsored by local or state organizations.

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 t he left and right to be sure ice and snow are not interfering with full left and right steering. If difficulty is encountered, check for ice and snow build-up that may be obstructing the steering linkage. Snow screens and bib kits are available through your dealer to help reduce snow and ice build-up.

Operation on Hard -Packed Snow or Slippery Surfaces

WARNING

Driving on ice or hard-packed snow reduces steering and braking control, which may result in serious injury or death. Slow down and use caution.

Excessive shifting of operator body weight when turning on hard-packed snow or ice may lead to loss of vehicle control and result in serious injury or death. Slow down to maintain control under these conditions.

It’s dangerous to drive on ice or other slippery surfaces. If it’s unavoidable, use extreme caution and operate at speeds no faster than a walk. Never attempt an abrupt change of direction. The chance of “spin-out” increases under these conditions.

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.

Operating in hilly terrain requires extreme caution to maintain balance and avoid roll-over. If climbing a hill is unavoidable, keep all your weight low and forward.

If you must cross the face of a slope, keep your weight on the uphill side of the machine 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 machine 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 machine, pull the rear of the snowmobile around and point the front end and skis downhill. Remount the machine, restart the engine, release the parking brake, and descend the hill carefully.

SAFETY

Operator Safety

Riding Downhill

When riding downhill, shift your weight to the rear of the machine 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 machine 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.

Do Not Operate Engine With Clutch Guard Removed

The clutch guard is designed to protect the operator from metal parts if the clutch should fail. Although the chance of failure is extremely remote, don’t defeat the purpose of the guard by removing it. It’s provided for your safety.

Do Not Operate Engine With 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 personal injury or damage to the engine.

SAFETY

Operator Safety

Do Not Operate Engine With Intake Silencer or Filter Removed

Damage to the engine may occur if the intake silencer or filter are removed.

Do Not Service Clutches You rself

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 machine into motion, but always operate within safety limits and, on 2-Up machines, with respect for a passenger. See page 84 for more detailed instructions on cold weather drive-away.

Machine Maneuverability

Control and maneuverability comes not only through the steering and skis, maximum control is achieved by shifting of body weight. Maneuverability will change for lighter operators or machines designed to carry a load or a passenger.

SAFETY

Operator Safety

Powder Snow Operation

Moveable hood closures are included on some Polaris snowmobiles. They are normally left open and are located on the front upper and lower hood openings. If operating in deep snow or in extreme cold conditions (below -20_F ), Polaris recommends closing the upper hood closure.

WARNING

Do not drive for prolonged periods on blacktop, gravel, or ice. Doing so could cause irreversible track damage and lead to serious personal 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. Driving in too little snow will result in excessive wear and damage to the slide rail, track and/or engine.

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

CAUTION

When operating on icy surfaces or hard-packed snow, avoid overheating the slide rail and track. Lack of lubrication and cooling will cause overheating of the slide rail and track, resulting in premature wear and failure. If frequently operating in low cooling conditions, see your dealer for an optional wheel kit that will reduce the wear from overheating.

SAFETY

Operator Safety

Your Polaris snowmobile is a well-engineered and well-constructed recreational vehicle. Follow the recommended maintenance program outlined beginning on page 106 of this manual to ensure that all critical components on the snowmobile are thoroughly inspected by your dealer at specific mileage intervals.

Driving 1-Up - Some Polaris snowmobiles are designed for a single rider only. A decal on the console of these models indicates single rider operation. See page 30 for decal location.

Driving 2-Up - Some Polaris snowmobiles are designed for two riders. A decal on the hood of these models indicates that the vehicle is designed for one operator and one passenger only. See page 30 for decal location.

Machines designed for two riders should never be operated with more than two people on board. When traveling with a passenger, it’s the driver’s responsibility to operate the machine safely.

Slow down! Control becomes more difficult with two people on board. More space is required to make turns, and longer distances are necessary for stopping.

SAFETY

Operator Safety

Responsible Driving

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.

n 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.

n Before allowing someone else 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.

n Don’t “jump” your snowmobile. Jumping may injure your back

because of spinal compression. 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.

n Be courteous to oncoming traffic by dimming your headlights and

reducing your speed. Your snowmobile is equipped with a high output headlamp system that may cause discomfort to operators of oncoming vehicles when on high beam.

n When traveling in a group of snowmobiles, don’t tailgate (follow

too closely). Allow ample stopping distances, and keep track of those following you. Drive defensively to avoid accidents.

n Don’t tempt anyone to steal your snowmobile or ride it without

permission. Remove the key from the ignition.

Polaris offers a wide range of adjustments so that every machine may be set up to suit individual needs. This section explains how to tailor the suspension and other features for an optimum riding experience.

THE PERFECT FIT

Front Suspension Adjustments

Break in the suspension for approximately 150 miles (240 km) and re-grease all suspension parts before fine-tuning adjustments are made.

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. The machine should be methodically tested under the same conditions after each adjustment (trail and snow conditions, vehicle speed, riding position, etc.) until the best ride is achieved. Adjustments should be made to one area at a time in order to properly evaluate the change.

All snowmobile suspensions have a front and a rear suspension, each of which has adjustment options.

Independent Front Suspension (IFS)

The IFS is made up of the skis (1), front shocks and springs (2), and the components that connect these parts to both the steering, such as the tie rods (3), and to the machine itself, such as the trailing arms (4). Front suspension adjustments include shocks, springs, toe, and camber.

NOTE: Although the front suspension on your machine may not look exactly like the illustration, it will have the same parts and functions as those illustrated.

IFS Adjustment Options

Front Suspension Adjustments

WARNING

Always verify ski alignment before making adjustments to the IFS. See page155 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. For the best ride, the spring preload should be set as low as possible to use the full travel of the ski shock, with occasional light bottoming. To determine if your machine is using full travel of the ski shock, push the jounce bumper down as far as it will go on the shock rod and test ride the machine. The bumper will move up on the rod in direct relation to the amount of travel. If the shock travel is full, the bumper will be seated at the top of the shock.

Adjusting Front Shock Spring Preload

Increasing spring preload will increase ski-to-ground pressure. Decreasing spring preload will decrease ski-to-ground pressure. When adjusting, be sure springs on both the left and right sides of the machine are at the same adjustment.

To increase front shock spring preload, grasp the spring and turn it to the right. Turn it to the left to decrease preload. In the illustrations at right, B indicates high preload and C indicates low preload.

Increasing the spring preload too much may adversely affect the handling of the snowmobile and the performance of the rear suspension. Decreasing the spring preload too much may allow the upper spring retainer to fall off. Always leave at least one thread showing above the nut (A).

CAUTION

Always leave one thread showing above the adjuster nut. On models equipped with a plastic adjuster nut, if the nut is unscrewed from the threaded body, the nut will break.

D Increase compression damping on Indy Select shocks (PE 52)

See your dealer for details. NOTE: Some models do not have shocks with thread adjustable spring

preload.

Changing Shock Valving

If you find that spring preload adjustment alone is not sufficient, changing the valving of your Fox you the ride adjustment you want. The purpose of shock valving is to control the stiffness of the shock’s movement.

t or RYDE FXt shocks may give

WARNING

Changing shock valving on Foxt and RYDE FXt shocks requires special tools and a sound knowledge of mechanical theory, tool use, and shop procedures to perform the work safely and correctly. Shocks contain high-pressure nitrogen gas. Use extreme caution when handling high-pressure service equipment. This work should be performed by a Polaris dealer.

THE PERFECT FIT

Front Suspension Adjustments

Indy Select IFS Shock

Some snowmobiles are equipped with Indy Select IFS shocks, which allow you to make adjustments to the compression valving of the front shocks by turning adjustment screws (A) located near the base of the shocks.

By turning the screw clockwise, the compression of the shock increases, stiffening the ride. By turning counterclockwise, the compression decreases, softening the ride.

The factory setting is in the softest position (screw all the way out counterclockwise). If bottoming occurs, the Indy Select feature should be used to achieve the desired ride effect. One-half turn will affect the ride considerably. There are about three turns of adjustment available. If experimenting with this adjustment feature, turn the screw only 1/4 turn at a time. And always adjust both shocks equally.

Rear Suspension Adjustments

Rear Suspensions

Polaris has a suspension t o meet your needs. Each is designed and set up to deliver a soft ride under average riding conditions. Rider weight, riding style, trail conditions, and vehicle speed all affect suspension action.

Each rear suspension can be adjusted to suit rider preference and deliver excellent performance for a given set of conditions. However, all suspension designs and adjustments involve a compromise, or trade-off. For example, a suspension set up for snow-cross racing would provide a very stiff ride on the trail. A suspension set up for trail riding would bottom out harshly on a snow-cross course.

A decal outlining rear suspension set-up options is located either under the hood or on the clutch cover. It provides a guideline for initial suspension set-up. Additional adjustments can be made from this point. Make adjustments to one area at a time so you can evaluate the change. For further assistance, see your dealer.

Suspension Performance Tips

D Rider weight usually determines the position at which the spring

preload should be set. However, this may vary with riding style. With a little experimentation, each rider can find a preferred set-up. These adjustments are easy to make, involve very little time or effort, and greatly affect the ride.

D In deep snow, a new Hi-fax will offer improved performance over

worn Hi-fax. It can also improve top speed.

D When riding on ice or hard-packed snow, adding a set of bogie

wheels to the rail may enhance the machine’s performance. Bogie wheel kits are available from your dealer.

D Polaris offers track kits for improved flotation in deep snow. See

your dealer for assistance.

NOTE: Keep the suspension pivot points lubricated. This will reduce moisture and rust build-up and ensure proper function of the suspension components. Grease rear suspension pivots before adjusting the rear suspension. Refer to Suspension Maintenance on pages 158-159.

Rear Suspension Initial Spring Preload Setting EDGE RMK (Sag Method)

T o set up the EDGE RMK rear suspension torsion spring preload, measure the distance between the ground and rear bumper. This is measurement X.

Take this measurement with no rider and with the rear suspension at full extension. NOTE: The rear bumper may need to be lifted upward slightly to fully extend the suspension.

Next, have the rider drop down hard on the seat and bounce up and down several times, collapsing t he rear suspension. With the rider seated, measure the distance between the ground and the rear bumper at the exact location used for measurement X. This is measurement Y.

To determine sag, commonly referred to as ride-in, subtract measurement Y from X (Sag=X-Y). Adjust sag by rotating the torsion spring preload cams located on the rear torque arm. Use the illustration or the decal found under the hood for reference. The ideal amount of sag for the EDGE RMK rear suspension is four inches (X-Y=4).

If the rear suspension rides in less than three inches or more than five inches with the torsion spring preload cams at their maximum range of adjustment, optional torsion springs (softer or stiffer, respectively) may be required. This is only an initial setup, and final spring preload may vary based on rider preference and riding conditions.

There are no external adjustments on the position sensitive shock. There is a performance PPS kit available for increasing damping. If you desire to have the internal valving changed, consult your dealer, or refer to the suspension troubleshooting decal located under your hood or on the clutch guard.

Suspension Coupling

On all Polaris snowmobile rear suspensions, there are two torque arms that control the movement of the rail beam. Prior to the advent of suspension coupling, these torque arms could move independently of each other. Rear suspension coupling links the movement of the front and rear torque arms to each other. There are two types of rear suspension coupling.

Front To Rear Coupling and the Front Rear Scissor Stop (FRSS)

The front rear scissor stop (FRSS) couples the movement of the front torque arm with the rear torque arm and limits the amount of independence between the movement of the front torque arm and the rear torque arm.

When hitting a bump, the front torque arm starts to compress. The FRSS links that movement to the rear torque arm, causing it to compress and raise the rear suspension up as one, allowing the suspension to hit the bump only once and eliminating kickback. Your FRSS is preset at the factory.

THE PERFECT FIT

Rear Suspension Adjustments

Rear To Front Coupling and the Rear Rear Scissor Stop (RRSS)

The rear rear scissor stop (RRSS) couples the movement of the rear torque arm with the front torque arm and limits the amount of independent movement between the rear torque and the front torque arm.

Adjusting the RRSS either allows more weight to transfer to the rear for more traction, or allows less weight to transfer to the rear, resulting in improved cornering performance. An adjustment dot is located on the RRSS. This dot is on the longest end of the scissor stop.

Rear Rear Scissor Stop (RRSS) - Attributes

Moving the RRSS to a higher position, or forward hole, will have the following effects on the suspension:

D Reduced weight transfer. D Improved chatter bump ride. D Improved cornering performance.

THE PERFECT FIT

Rear Suspension Adjustments

Weight Transfer During Acceleration

Xtra-10 and EDGE Rear Rear Scissor Stop (RRSS)

The preferred method for controlling weight transfer during acceleration of the EDGE rear suspension is by adjusting the rear rear scissor stop (RRSS). The RRSS is located in the best overall trail riding position when delivered from the factory.

To decrease weight transfer under acceleration (for improved cornering), rotate the RRSS to a higher position with the scissor stop tool (1) located in your tool kit.

To increase weight transfer or ski lift during acceleration, move the RRSS to the rearward hole on high position. The RRSS may also be rotated to a lower position for even more weight transfer if desired.

A - Stock Position - This setting is most desirable for trail riding.

B - Medium or High Position (standard hole location) - This setting will decrease weight transfer.

C - Rearward Upper Position (optional hole location - This setting will increase weight transfer.

NOTE: Your dealer can help you with initial set-up and additional setup instructions to help you achieve your optimum ride.

Xtra-12 Rear Rear Scissor Stop (RRSS)

The RRSS on Xtra-12 suspensions is not adjustable.

THE PERFECT FIT

M-10 Suspension

Before proceeding with the tuning of your M-10 suspension, you should familiarize yourself with the following terms:

Description of M-10 Features

Long Travel - Refers to the over 10″ of REAL travel that the M-10 has between the rear arm cross-shaft and the slide rail. this is the location to measure suspension vertical travel. In the Edge Chassis, the rear axle travel is 13.9”.

Biased Couple - Describes the linked relationship between the front and rear arms of the M-10. When the M-10’s front arm contacts a bump, the couple forces the rear arm to react instantly. This limits the angle of incidence between the rail and bump as the rear arm crosses it. the flatter this angle is kept, the less secondary reaction (kick) the rider will feel, and better maintenance of TRACK TENSION can be attained through the full 10″ travel.

Couple Blocks - Are the plastic sliding blocks located at the rear of the rail. These pieces facilitate the M-10’s actual couple function.

Advanced Ride Control (ARC) - ARC geometry decelerates shock and spring speed throughout compression travel making the shocks very sensitive to sled speed. This enables large strokes to be used in nearly all conditions, high or low speed, delivering huge benefits in rider comfort.

On return travel, the shock speed or rate is increased, which in effect delivers “RISING RATE” on the rebound stroke. The mechanical advantage of the system over the stored spring energy is very high, especially when compared with conventional systems. The result is excellent control of the “kick” and normal return forces which FAST has identified as being the most upsetting to the rider during travel over rough conditions.

Full Range Adjuster (FRA) - FRA refers to the adjustable lower rear shock attachments. Major adjustments in rider weights can be made from 100 lbs. at the rear (#1 SOFT position of the slot) to 350 lbs at the front (#4 FIRM position of the slot). Changing this location has two effects on tuning. Moving the shock forward increases shock speed, resulting in firmer damping on both compression and rebound. It also increases the effect of the rear spring by displacing it further.

The adjuster is infinitely variable between those settings. Using a 9/16″ wrench, adjustments are made quickly and easily.

THE PERFECT FIT

M-10 Suspension

NOTE: The M-10 has been designed to be very sensitive to rider weight. Changes in rider weight of 25 lbs. or more might require appropriate changes in FRA settings. Refer to the chart on page 64 for specifications.

Internal Floating Piston Shock - A high-pressure gas shock absorber, with its gas reservoir inside the main shock body. Shock oil, is kept separate from the gas by m eans of a floating internal piston. The shock used on the front arm of the M-10 is of this type. The advantages of these shocks are consistency and reduced fade performance.

Remote Reservoir Shock - When a shock’s nitrogen and oil are separated by a floating piston or bladder in an external chamber, they are referred to as REMOTE RESERVOIR shocks. Some advantages of this type of shock are consistency in shock performance, reliability, and reduced fade performance. The M-10’s rear shock absorber is of this type.

Threaded Preload Adjuster - The top section of the X-OVER TUBE (back tube at the top of the rear shock) has a threaded collar on it. The rear spring has a lock tab that fits into the collar to allow easy PRELOAD adjustment.

T o increase PRELOAD, use a kit spanner wrench to rotate the X-OVER TUBE towards the PTO side of the sled (clockwise when viewed from below). Rotate towards the MAG side to decrease PRELOAD (counter-clockwise when viewed from below). For more information, refer to page 65.

DEFINITION OF TUNING TERMS

Spring Rates - Describes how many pounds of force it takes to compress a spring one inch. Therefore, if a 250 lb weight was set on top of a spring and it compressed one inch, it would be rated at 250 lbs/inch.

THE PERFECT FIT

M-10 Suspension

Optional S pring Rates - Optional springs have been designed to allow adaptation of the M-10 to the varied needs of our customers. The 140 lb/in option front arm spring would be used when very light loads are encountered such as very smooth trails, deep powder or by very light riders.

The 235/415 lb rear arm spring option would be used by riders in high load situations such as heavy riders on rough trails or combined total rider weight of over 350 lbs.

The available springs for M-10 are as listed below.

Location Spring Rate Polaris PN

Front Arm Std Soft Firm

Rear Arm Std Soft Firm

Overload 1000 7041936--067

Preload - Is basically the pretensioning of a spring by installing it on a shock at less than its free length - Free Length -- installed Length = Inches of PRELOAD OR 10.5″ -- 9.75″ =.75″ of PRELOAD

Dual Rate - Refers to 2 different SPRING RATES designed into one spring. Notice that M -10 coil springs are often “dual rate” having a soft (closely wound) area and a firm (loosely wound) area.

Over Load Spring - Located inside the main rear spring, contact is made with this spring only when the X-OVER tube comes in contact with it towards the end of the travel, reducing bottoming of the rear suspension.

X-OVER or CROSS OVER - Describes the transition from one spring rate to another. during compression travel, the space between the closely wound coils eventually disappears. At this point, the spring “CROSSES OVER” from the soft to the firm rate. This term also includes the transition that occurs when the overload s pring is engaged by the “X-Over Tube” on the rear shock.

SAG SETTINGS - Describes the difference in height of the rear bumper from the sleds fully extended position to its loaded height with the rider seated on the sled.

A good initial starting point is 4″ of SAG. Note that this measurement is at the rear bumper. Too much SAG will result in bottoming and too little SAG will result in reduced rider comfort.

SAG travel i s used to control ride quality and rebound travel and off the tops of bumps. SAG is controlled by FRA and PRELOAD settings. For more information, refer to the INITIAL SET-UP REFERENCE CHART found on page 64, or the suspension set up decal located under the hood of the snowmobiles.

INITIAL SET UP AND CALIBRATION

Your M-10 is a precision instrument which MUST be optimized for your specific needs and riding conditions. The following introduction and information has been compiled to assist you in tuning your M-10 to its maximum potential.

THE PERFECT FIT

Rear Suspension Setup

1. Adjusting the Full Range Adjuster (F.R.A.)

1. Refer to the initial set-up reference chart (located under the hood of your snowmobile and on page 64) to determine the desired F.R.A. position.

2. To adjust, loosen the hex bolts (A)attaching the rear lower shock cross shaft to the rail beam.

3. Using a 9/16” wrench, loosen the jam nuts (B) on the preload bolts.

4. Adjust the preload bolts (C) to the desired F.R.A. position.

5. Tighten the jam nuts (B). NOTE: Make certain the preload bolt is contacting the slide block before tightening the jam nut.

6. Tighten the hex bolts (A) and torque to 35 ft. lbs.

NOTE: The FRA setting is the primary rear suspension adjustment. It will have the MOST effect on the rear suspension performance.

If the M-10 is new, it will take anywhere from 25 to 200 miles to properly break in the springs and shocks. At the time of break-in, the suspension will get softer and may require the FRA to be re-adjusted

Setting the Rear Compression Spring Preload Dimension B

1. Using the spanner wrenches in your tool kit, rotate the x--over tube assembly to achieve the desired spring preload setting. Be certain the aluminum locknut and adjuster collar are locked against each other before starting adjustment.

2. While adjusting, keep in mind that spring preload is a FINE adjustment. COARSE adjustments should be made using the FRA.

NOTE: Preload is set “softest” when the preload dimension (B) is equal to zero. Adjusting spring preload beyond this could cause damage to the threads.

Adjusting the X-over Tube Length - Dimension C

1. Use the spanner wrenches located in the tool kit to unlock the upper lock nut from the adjuster collar.

2. Turn the adjuster collar to the appropriate or desireddimension for the rider’s weight (refer to the initial set-up reference chart located under the hood of your snowmobile). Tighten the upper lock nut firmly against the adjuster collar using the spanner wrenches.

NOTE: The correct setting of the X-Over tube length enables the M-10 to deliver superior performance in “bottoming” situations. This adjustment has no effect on spring pre-load or general ride characteristics of your M-10 rear suspension, only bottoming resistance.

THE PERFECT FIT

M-10 Suspension

SETTING LIMITER / SKI PRESSURE

Your M-10 rear suspension has come from the factory set up to delivery the optimum balance between ride and handling. If a rider

prefers more ski pressure for improved steering performance, adjustments can be made to the front limiter strap.

1. To set t he limiter, determine if the rider prefers comfort or control. Lean toward the #4 setting for comfort and towards the #3 settings for aggressive riding.

2. For full hole adjustments remove the 5/16” nut and flat washers from the lower attachments of the limiter straps and relocate straps to the desired position (i.e. position 4 to 3). Replace the nut and washer and re-tighten.

For half-hole increments (such as 3/4), the limiter straps have slots at the

upper pinch bolt. These slots allow the bolts to be loosened (rather than removed) for half-step adjustments. It is now easy to change to half-step hole positions (re-tighten pinch bolts if loosened).

3. FRONT ARM MOUNTING HOLES. There are also 2 front arm mounting holes in the slide rail that can adjust ski pressure. The lower hole (A) increases ski pressure while the upper hole (B) decreases ski pressure.

NOTE: By design, the B IASED COUPLE suspension system displaces the rear arm as the front arm is compressed. This means that when you raise the front limiter strap at some point you will collapse the rear suspension arm, which will affect SAG height, and reduce rear suspension travel.

SAG / RIDE HEIGHT SETTINGS

1. To check if the FRA settings are close before riding, check the SAG settings. Raise the rear bumper until the suspension i s fully extended (rearshock will not extend any further) and measurethe distance from the ground to the bottom of the bumper as shown to attain dimension X and record it.

2. Next, have the rider sit on the sled and bounce on the seat a couple of times to set in the M-10. While the rider remains seated, m easure the distance from the ground to the top of the bumper to attain dimension Y and record it.

3. Next subtract Y from X and you will have the S AG settings (X -- Y = SAG SETTING or 21 -- 17 = 4). The correct amount of SAG for the M-10 rear suspension is 3” - 5”.

NOTE: The FRA setting is the primary rear suspension adjustment. It will have the MOST effect on the rear suspension performance.

Traction Products

Another way to tailor your machine is to install traction products. See your dealer about installing studs and/or carbides. Many tracks with deep lug designs cannot be studded, but your dealer will be able to offer advice and assistance.

NOTE: Polaris does not recommend the use of traction products on WideTrak snowmobiles.

Traction Products

NOTE: Before equipping your machine with traction products, be aware of the laws in your area pertaining to the use of traction products.

Track studding will enhance braking control on hard-packed snow or ice, but extreme caution is still required on such surfaces. Steering ability may be reduced on hard-packed snow or ice.

A skag is a replaceable bar attached to the underside of the ski to assist in turning the snowmobile and to prevent ski wear caused by contact with roads and other bare terrain. The addition of carbide skags is recommended with studded tracks to help maintain proper vehicle steering and control. Similarly, if your machine is equipped with carbide skags or you’re adding them, it may be necessary to add track studs to maintain proper vehicle control. Proper balance must be maintained between the number of studs and the length of carbide on skags. The more studs used, the longer the carbide on the skags should be. See your dealer’s track studding chart for recommended studding and skags.

Inspect skags and studs frequently. Worn studs or skags may reduce steering and braking control on hard-packed snow and ice. Replace worn studs and skags to maintain proper balance and vehicle control.

When studded tracks are used, increased wear to the brake pads will result from increased braking. Extended-wear brake pad kits are available. See your dealer for more information.

THE PERFECT FIT

Accessories

CAUTION

Aggressive studding patterns may require grinding protruding stud bolts flush to prevent idler wheel damage. Maintain track tension on studded tracks on the tight side of the spec to prevent heat exchanger damage. Center of stud must be at least 1 1/8″ (2.86 cm) from outside edge of the track.

CAUTION

If traction products are added to the track, wear strips must be installed in the tunnel to avoid excessive wear.

Never add shims to the wear strip. Track damage will result because of lack of clearance between upper carrier wheels and track.

Use of studs longer than 1″ (2.5 cm) on machines equipped with center coolers will result in center cooler damage or damage to the tunnel.

Use only Polaris traction products on your snowmobile. Track warranties are void if track damage or failure results from improper or excessive stud installation or the use of non-Polaris t raction products.

WARNING

Loss of control can result in serious personal injury or death. Proper balance of traction products on the skis and track must be maintained to obtain proper vehicle control on hard-packed snow or ice. See your dealer for assistance.

THE PERFECT FIT

Accessories

Wear Strips

To avoid excessive tunnel wear, tunnel wear strips must be installed whenever track studding is used. Several wear strips are available. See your dealer for more information.

Some models are manufactured with tunnel wear strips or wear strip coolers installed. Refer to your Owner’s Manual Supplement to determine if your model has wear strips.

Wear strips are designed for a specific stud length. See your dealer’s studding chart for recommended traction accessories.

GETTING READY TO RIDE

Check Before Starting Engine

WARNING

Worn, damaged, or malfunctioning components may cause serious injury or death. Before starting the engine, check all components to be sure of proper operation.

Read and Understand Your Owner’s Manual

Read the Owner’s Manual completely and refer to it often. We’ve attempted to provide as much information as possible to alert you to the safety requirements of snowmobiling.

Check Throttle and Brake for Proper Operation

The throttle and brake are the primary controls of your snowmobile. If either should malfunction, loss of control could result.

Make sure the throttle lever compresses evenly and smoothly. The lever should immediately return to the idle position without binding or hesitation. If the throttle does not function smoothly, DO NOT start the engine. Have the throttle serviced immediately.

The need for a properly functioning brake is critical. Your snowmobile is equipped with the highest quality brake system available. Check the brakes for correct operation before starting the engine.

Throttle Safety Switch

Test the throttle safety switch system daily, before the machine is operated.

GETTING READY TO RIDE

Check Before Starting Engine

Hydraulic Brakes

Properly functioning brakes are critical to your safety. Always check the following items to assure proper operation before starting the engine.

Brake Lever Travel

When the brake lever is squeezed, it should move no closer to the handgrip than 1/2″ (1.3 cm) (A). A distance less than this indicates low brake fluid level or air in the hydraulic system. Refer to the brake bleeding information on page 137.

Lever Feel

A hydraulic system multiplies the force of your hand squeezing the brake lever. P roper operation depends on an adequate supply of air and moisture-free hydraulic brake fluid in the system. If the brake lever feels “spongy” when squeezed, check the level and condition of the fluid. Also check for the presence of air in the fluid system. Refer to page 137 for more information, or see your dealer for service.

Replace brake fluid at least every two years with Polaris DOT 3 high temperature brake fluid. All DOT 3 brake fluid is not alike. Use only Polaris brake fluid (PN 2870990).

WARNING

Continued use of “spongy” brakes may cause a complete loss of brakes, which could result in serious injury or death.

GETTING READY TO RIDE

Check Before Starting Engine

Mechanical Brakes

Brake Lever Travel

Firmly depress the brake lever. Measure the distance (A) between the lever and brake block. The distance should be no more than 3/4″ (1.9 cm).

If the distance is greater than this recommendation, the brake cable must be adjusted. Refer to mechanical brake adjustment information on page 138.

GETTING READY TO RIDE

Check Before Starting Engine

Park Brake Lever Lock

Your snowmobile may have a park brake lever lock located over the brake lever. Use the brake lever lock only when you want the machine to remain stationary; for example, when parked on an incline for a period of five minutes or less. To apply the lock, squeeze the brake handle and push forward on the brake lever lock. Hold the lock forward and release the brake handle.

If the brake handle is squeezed tightly enough, the lock will move freely into place. Do not force the lock or it may break. To release the lock, squeeze the brake handle until the lever returns to the unlock position. The park brake light on the console will light up when the park brake lever lock is set and the engine is running. It will also be lit when the service brake is in use. If the park brake light does not come on when the park brake or service brake is in use, have it serviced by your dealer.

1. Brake Handle

2. Park Brake Lever Lock (not all models have a park brake)

3. Master Cylinder Reservoir / Cover

4. Fluid Level Indicator

WARNING

If the park brake lever lock is partially or entirely engaged while riding, overheating of the brakes could occur, resulting in brake damage. In extreme cases it could cause a fire, which could result in serious injury or death.

GETTING READY TO RIDE

Check Before Starting Engine

Check for Proper Op eration o f Steering System

Manually turn the skis completely to the right and to the left. If any difficulty is encountered, check for ice and snow build-up that may be obstructing the steering linkage. Make sure all greasable components are properly lubricated.

Track Inspection

WARNING

Always inspect the track for damage before using the vehicle. Operating the snowmobile with a damaged track increases the possibility of track failure, which could cause loss of control resulting in serious injury or death.

Use of t raction products such as studs increases the possibility of track damage and/or failure. Driving at high speeds for extended periods of time in marginal lubrication could severely damage track rods, break track edges, and cause other track damage. Examples of m arginal lubrication would include frozen bodies of water without snow cover, icy trails, and no-snow conditions.

NOTE: Track damage or failure caused by operation on ice or poor lubrication conditions voids the track warranty.

Check for Securely Latched Hood

The hood of the snowmobile protects the operator from moving parts as well as aiding in sound emission control and other functions. Under no circumstances should your snowmobile be operated with the hood open or removed.

GETTING READY TO RIDE

Start the Engine and Check

n Transmission: Make sure the reverse is not engaged before

starting your machine.

n Engine Stop Switch: Check the auxiliary shut-off switch for

proper operation. Push down to stop the engine. Pull up to release and start the engine.

n Tether Switch: If your machine has a tether switch, make sure the

engine shuts off when the tether is removed from the switch.

n Lighting Check: Check the headlight (high and low beam),

taillight, and brake light for normal operation.

n Mirror Adjustment: Adjust your mirrors so they can be used to

their full advantage.

n Check Surroundings to Verify Clear Operating Area

Make sure you have a clear area all around your snowmobile, including an area clear of bystanders. There’s always the possibility of some sideways vehicle movement, of applying a little more throttle than intended, or of debris being thrown by the track. If the surrounding area is clear you before you start, you can devote your full attention to operating the snowmobile.

release the key to “ON” and flip the choke toggle to “OFF.” If the engine

slows or wants to stop, use intermittent choking to “HALF ON.”

5. WideTrak models can also be warmed up with the transmission in neutral and the brake engaged. This will allow the engine to warm without engaging the drive system.

NOTE: Don’t leave the machine in this position for more than five minutes. Engine RPM should be at idle before shifting the transmission.

Starting a Warm Engine

1. Turn key to “ON.”

2. Pull kill switch (shut-off switch) up to “RUN.”

3. Grasp starter handle and pull slowly until recoil engages; then pull to start.

If the engine does not start on the first pull, slightly depress the throttle with your left hand (no more than 1/4″ open), and pull the rope with your right hand. When the engine starts, immediately release the throttle.

OPERATION

Engine Break-In

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.

CAUTION

Never mix brands of two cycle oil. Serious chemical reactions can cause injection system blockage, resulting in serious engine damage and the voiding of engine warranty. The only oil recommended for this system is Polaris injection oil. This oil has been specially formulated for all temperatures and has extreme cold flow characteristics.

Do not operate at prolonged full throttle for the first three hours of operation. Vary the throttle openings and machine speeds to reduce friction on all close fitting machined parts and allow them to break in slowly without damage.

Adequate snow coverage is necessary to properly break in your machine. Avoid operating on ice, hard-packed surfaces, or roads. Snow will provide the lubrication and cooling your snowmobile needs for proper break-in. 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.

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

OPERATION

Engine Break-In

Oil Injection System

CAUTION

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

Always fill the oil reservoir when refueling. Fuel-to-oil mix ratios are controlled by the oil pump and correspond to the engine’s RPM and throttle valve opening.

Variable Exhaust System

All snowmobile engines equipped with variable exhaust valves should use VES 2 Cycle Oil (see chart on page 87).

Lubrication

The only source of engine lubrication for your engine comes from lubrication added to the fuel and oil injection systems. Use only Polaris products. We are continuously testing lubricants and provide the highest performance products available for your engine. Please refer to the table below to determine the preferred and acceptable oils for use in your engine.

Never mix other brands of oil. They may 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.

OPERATION

Track Warm-Up

WARNING

A loose track or flying debris could cause serious personal injury or death. Stand clear of the front of the machine and the moving track. Never hold the snowmobile up or stand behind it while performing this procedure. Do not use too much throttle during warm up or when track is free-hanging. Be sure the rear support is stable.

NOTE: The outside temperature will determine the amount of track warm-up required.

With the snowmobile securely supported by the rear bumper, and the track approximately 4″ (10 cm) off the ground, follow these steps t o ensure proper warm-up of the engine, drive train, and track.

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

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

revolutions.

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

the machine to the ground.

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

This will loosen frozen snow from the ski bottoms, allowing the machine to move forward more easily .

OPERATION

Track Warm-Up

5. The engine, drive system and track are now properly warmed up and the machine may be driven following normal safety practices.

WARNING

Always inspect for track damage before operating the snowmobile. 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.

OPERATION

Fuel

Gasoline is extremely flammable and explosive under certain conditions.

Always stop the engine and refuel outdoors or in a well ventilated area.

Do not smoke or allow open flames or sparks in or near the area where refueling is performed or where gasoline is stored.

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

If you get gasoline in your eyes or if you swallow gasoline, see your doctor immediately.

If you spill gasoline on your skin or clothing, immediately wash it off with soap and water and change clothing.

Never start the engine or let it run in an enclosed area. Gasoline powered engine exhaust fumes are poisonous and can cause loss of consciousness and death in a short time.

WARNING

The engine exhaust from this

product contains chemicals known

to cause cancer, birth defects or

other reproductive harm.

OPERATION

Fuel

The fuel used in your Polaris engine is as important to engine life and performance as the lubricant used.

Most Polaris engines are designed to run on 87 octane non-oxygenated or 89 octane oxygenated pump gasoline. There’s a great deal of variability in the quality of the 87 octane gasoline available across the country, so we encourage the use of premium fuel when possible. NOTE: Some Polaris snowmobiles require premium gasoline. Check your Owner’s Manual Supplement to determine what type of fuel your machine requires.

Premium Fuel Switch

Some Polaris snowmobiles are equipped with a key function to adjust the timing on the machine as you change fuels. It’s very important to the life of your engine that you use this feature.

When using fuels with a pump-posted octane rating of 91 or higher, turn the key switch to “ON/PREM.” When the engine is started, a yellow “Premium Fuel” light illuminates on the instrument panel. When the key is in this position, the fuel must be a minimum of 91 octane.

Most high performance machines require the use of premium fuels. Substituting other fuels may cause engine damage.

Premium Fuel Setting

Regular Fuel Setting

CAUTION

Using lower than the recommended octane fuels or operating with obstructed fuel systems will lead to costly engine damage.

OPERATION

Fuel

Premium Fuel Switch

If you’re uncertain about the quality or octane rating of the fuel you use, turn your key switch to “ON/REG.” The “Premium fuel” light will go out. This setting will adjust the timing of your engine to run on fuels with 87 octane or higher. Polaris does not recommend using fuel with lower than 87 octane. Running your machine on “ON/REG” will help protect your engine from damage caused by low octane fuels.

Fuel Reserve Capacity

On models equipped with fuel reserve, there are approximately two gallons of fuel left in the tank when the fuel gauge reads “RES.”

Fuel System Deicers

If you use non-oxygenated fuel, Polaris recommends the regular use of isopropyl-based fuel system deicer (Polaris PN 2870505). Add one to two ounces per gallon (8-16 milliliters per liter) of gasoline to prevent engine damage resulting from fuel system icing and lean fuel mixtures.

Never use deicers or additives containing methanol.

If you use oxygenated fuel containing ethanol, additional alcohol deicers or water absorbing additives are not required and should not be used.

CAUTION

Prolonged exposure to petroleum based products may damage paint. Always protect painted surfaces when handling fuel.

OPERATION

Oil

Low Oil Indicator Light

The low oil indicator light (standard on most models) will indicate when to add oil. However, always check the oil level when refueling.

CAUTION

When the low oil indicator light is on, oil should be added before further operation of the snowmobile. Visually check the oil level in the bottle. The engine may be operated as long as oil is visible in the oil tank. If oil is not visible, continued operation may cause serious engine damage.

Never mix brands of two cycle oil. Serious chemical reactions may occur, causing injection system blockage This may result in serious engine damage and the voiding of engine warranty.

Always maintain the oil level above the tank’s low level line. This is especially important when the machine is operated in mountainous terrain. Maintaining the proper oil level will prevent system aeration and possible loss of pumping action, which could result in engine damage.

OPERATION

Oil

Low Oil Level

Always do a visual check of the oil level when refueling. In the illustration, * indicates a low oil level. When the oil reaches the low level mark, add one U.S. quart of oil to the tank.

Always use a Polaris oil cap, never substitute. Your Polaris oil cap may be vented to allow proper oil flow.

NOTE: Not all models have a coolant bottle attached to the oil tank.

OPERATION

Carburetion

Proper carburetor adjustment is critical. A lean mixture (too much air, too little fuel) may result in piston burning, bearing failure, or complete engine failure. A rich mixture (too much fuel, too little air) may foul plugs and cause generally poor engine performance.

A lean mixture may be caused by things like fuel line restrictions, foreign matter in the carburetor, or clogged fuel filters. A rich mixture may be caused by snow build-up on t he pre-filter in the air intake system. Either condition may be caused by improper carburetor adjustment.

All carburetors have been preset at the factory for adequate fuel supply. Higher altitude operation may require different adjustments and settings. NOTE: RMK models are preset to operate at altitudes of 6000-9000 feet above sea level. See page 128 for more information. Your dealer has the training and tools required to perform any adjustments for you.

WARNING

Carburetor adjustments must be performed by your dealer, since mistakes may result in possible operator safety hazards as well as serious engine damage.

OPERATION

Engine Stop Switch

Push down on t he engine stop switch (A) to stop the engine in an emergency. This will ground out the ignition and bring the engine to a quick stop. To restart the engine, the switch must be pulled up to “ON.”

Throttle Safety Switch

Test the throttle safety switch system daily before operation.

While seated in a normal riding position, and with the engine idling, hold the throttle lever pin stationary by exerting pressure on the pivot pin in the direction shown in the illustration (B). Apply a slight amount of throttle. A properly functioning switch must shut down the engine.

The throttle safety switch is designed to stop the engine whenever all pressure is removed from the throttle lever and the throttle cable or valves do not return to the normal closed position.

WARNING

If the throttle safety switch does not shut off the engine during a carburetor/throttle system malfunction, immediately push down the engine stop switch. Do not start the engine until the malfunction has been corrected by your dealer.

OPERATION

Throttle Lever

WARNING

An improperly functioning throttle lever may cause erratic machine behavior and loss of control, which could result in serious injury or death. If the throttle lever does not work properly, DO NOT start the engine.

If the engine stops abruptly when the throttle lever is released:

1. Turn the i gnition switch to “OFF.”

2. Visually inspect the throttle cable and carburetor(s) t o determine what caused the safety switch to activate.

3. Test the throttle lever by compressing and releasing it several times. The lever and cable must return to the idle position quickly and completely.

4. If the throttle lever operates properly, turn the ignition switch on and go through normal starting procedures.

5. If the engine doesn’t start, take the snowmobile to an authorized Polaris dealer for service.

Excessive free play in the throttle cable may cause the safety switch to activate, preventing the engine from starting. If this occurs, return the machine to an authorized Polaris dealer for service.

If an emergency exists and it’s necessary to start the engine, the throttle safety switch and engine stop switch may be disconnected from the wire harness. When these switches are disconnected, the ignition key switch must be used to shut off the engine. DO NOT continue to operate the machine with the throttle safety switch disconnected. Return the machine to an authorized Polaris dealer for service as soon as possible.
