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. Teach 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 n ot 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.

INTRODUCTION

Vehicle Identification Numbers

Record your snowmobile’s identification numbers and key number in
the spaces provided below . The key nu mber is stamped on the spare key .
The number on the rubber-coated key is in the form of raised dots.
Remove the spare key and store it in a safe place. An ignition key can be
duplicated only by ordering a Polaris key blank (using your key num­ber) and mating it with one of your existing keys. The ignition switch
must be replaced if all keys are lost.

SAFETY

Operator Safety

Follow the recommended maintenance program outlined beginning on
page 68 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 ope rating
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

10

SAFETY

Operator Safety

Stay Clear of Track

Your snowmobile is propelled by a revolving track that must be partially
exposed for proper operation.

WARNING! Serious injuries may result if hands,
feet, or clothing become entangled in the track.
Be alert when riding, and remain properly seated
to stay clear of the track. 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, raise the hood, make the adjustment, secure shields and guards,
secure the 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.

11

SAFETY

Operator Safety

Riding Position

Operating a snowmobile requires skill and balance for proper control.
Rider positions may vary with experience; 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.

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 g one. 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

Riding Apparel

Helmet

Wearing a helmet can prevent a severe head injury. Whenever riding a
Polaris vehicle, always wear a helmet that meets or exceeds established
safety standards.

Approved helmets in the USA and Canada bear a U.S. Department of
Transportati on (DOT) label.

Approved helmets in Europe, Asia and Oceania
bear the ECE 22.05 label. The ECE mark consists
of a circle surrounding the letter E, followed by the
distinguishing number of the country which has
granted approval. The approval number and serial
number will also be displayed on the label.

Eye Protection

Do not depend on eyeglasses or sunglasses for eye protection. When­ever riding a Polaris vehicle, always wear shatterproof goggles or use a
shatterproof helmet face shield. Polaris recommends wearing approved
Personal Protective Equipment (PPE) bearing markings such as VESC
8, V-8, Z87.1, or CE. Make sure protective eye wear is kept clean.

Clothing

Be prepared, be warm and be com­fortable when riding. Be aware of
the weather forecast, especially the
windchill, and dress accordingly.
See the chart on page 21.

WARNING! Avoid wearing loose
clothing or long scarves, which can
become entangled in moving parts and
cause serious injury. Always wear an
approved helmet and eye protection.

Disabled Operators

Safe operation of this rider-active vehicle requires good judgement and
physical skills.

WARNING! Operators with cognitive or physical disabilities have an increased
risk of loss of control, which could result in serious injury or death. Do not allow
disabled persons to operate this vehicle.

Rider Capacity

Your Polaris snowmobile is designed for a single rider only. Do not
carry a passenger.

Excessive Speed

WARNING! High speed driving, especially at night, could result in serious injury
or death. 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.

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

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.

17

SAFETY

Operator Safety

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 hard ­packed snow reduces steering and braking control, which may result in loss of
control and serious injury or death. Slo w down and use extra caution when
operating on slippery surfaces.

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 rollover.

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 fro m 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.

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 loos ened 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 and, on 2-up machines, with respect for a passenger .

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 or a passenger.

19

SAFETY

Operator Safety

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 surface s . 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.

20

SAFETY

Operator Safety

Driving Responsibly

Every snowmobile handles differently, and even the most docile condi­tions may become dangerous if operators drive improperly. If you’re
new to snowmobiling, acquaint yourself with the machine and with
what it will and won’t do under various conditions. Even seasoned driv­ers should spend some time getting the feel for a machine before
attempting ambitious maneuvers.

• 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.

Reverse Warning

Polaris snowmobiles equipped with
electric reverse have a reverse warning
decal on the console.

WARNING
Reverse operation, even at low speeds,

can cause loss of control resulting in seri­ous injury or death. To avoid loss of con­trol, always:

• Look behind before and while backing
up.

• Avoid sharp turns.

• Shift to or from r e verse only when
stopped.

• Apply throttle slowly.

NOTE: For more information, see
Owner's Manual.

If electric revers e:

• Machine stopped and engine at idle, push yellow button on LH control to
reverse. Flashing light on dash indicat es reverse operation.

• Push button again to return to forward.

Operation Warning

The operation warning decal is located on the console of all Polaris
snowmobiles.

WARNING

• To avoid serious injury or death, read and understand all warnings and the
Owner’s Manual before operation. If manual is missing, contact a Polaris
dealer for a replacement.

• This vehicle is capable of high speeds. Buried objects or uneven terrain can

Operation Warning

(continued from previous page)

• Excessive speed, especially at night or with limited visibility, can result in
insufficient time for you to react to terrain changes, to avoid unexpected
obstacles, or to stop safely.

• Never consume alcohol or drugs before or while operating this vehicle.

• In an emergency, push down the Auxiliary Shut-Off Switch, located on the
top of the throttle control assembly, to stop the engine. Then pull the brake
lever to stop.

• Always wear an approved helmet, eye protect ion, and adequate clothing
while operating this vehicle.

• This vehicle is designed for adult use only. Check local laws for age require­ments.

• When operating with a passenger (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 r educed. 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 carb id es to track studs. 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.

FEATURES

Detonation Elimination Technology (DET)

A detonation sensor monitors the engine and responds to detonation by
automatically reducing the engine timing and adding fuel. This results in
decreased engine RPM and performance.

Effect of DET

The DET system prevents damage to the engine from detonation while
developing the maximum power of the engine safely. If the system
senses detonation beyond a preset limit, it retards ignition timing and
adds fuel to reduce the detonation and prevent engine damage.

When the detonation returns to a permissible level, the system will
return spark and fuel to normal, allowing the engine to run at rated
power levels.

Sensor Fail-Safe

The DET includes a sensor fail-safe system to prevent the engine from
damage if the sensor fails, becomes disconnected or is unable to detect
detonation. The rider will experience a loss in power. The sensor must
be reconnected or repaired to regain full power.

TIP:The check engine light will flash six times if the sensor fails or becomes

disconnected.

IQ Front Suspension Adjustments

Independent Front Suspension (IFS)

Break in the suspension for approximately 150 miles (240 km) before
making any fine-tuning adjustments.

Settings will vary from rider to rider , depending on rider weight, vehicle
speed, riding style, and trail conditions. We recommend starting with
factory settings and then customizing each adjustment individually to
suit rider preference. The snowmobile should be methodically tested,
one change at a time, under the same conditions (trail and snow condi­tions, vehicle speed, riding position, etc.) after each adjustment until the
best ride is achieved.

WARNING! Always verify ski alignment before making adjustments to the IFS.
See page 98 to check alignment. If the skis are misaligned, see your dealer, as

Standard Shocks

The tension at which the shock coil spring is set is called spring preload.
For the best ride, the suspension should be adjusted to use the full travel
of the shocks with occasional light bottoming.

The front springs can be changed if spring preload alone isn't sufficient
and further adjustment is desired to control suspension stiffness. See
your Polaris dealer for more information.

Rear Suspension Adjustments

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 adjustm en ts involv e 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.

Make adjustments to one area at a time so you can evaluate the change.
For further assistance, see your dealer.

Suspension Performance Tips

• 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.

• In deep snow, a new rail slide will offer improved performance ov er a
worn slide. It can also improve top speed.

TIP: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 the suspension lubrication information beginning on page 73.

42

THE PERFECT FIT

Rear Suspension Adjustments

Initial Spring Preload Setting (Sag Method)

To set up the 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.

TIP: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 the 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. See illustration. The ideal amount of sag for this rear
suspension is five inches (12.7 cm) (X-Y=5 in./12.7 cm).

If the rear suspension rides in less than four inches or more than six
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.

• Turn the screw clockwise for a stiffer
ride.

• Turn the screw counterclockwise for a
softer ride.

If bottoming continues after the screw has

nSteering System

Manually turn the skis completely to the right and to the left. If any dif­ficulty is encountered, remove any ice and snow build-up that may be
obstructing the steering linkage.

n Track Inspection

WARNING! 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. Always inspect the track for damage before using th e vehicle.

Use of traction 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 marginal lubri­cation would include frozen bodies of water without snow cover, icy
trails, and no-snow conditions. Track damage or failure caused by oper­ation on ice or poor lubrication conditions voids the track warranty.

Deep Lug Tracks (if equipped)

The 2.4" powder track is designed specifically for deep snow applica­tions. Operation in low snow conditions at high speeds may cause track
lug separation. Track lug separation is not covered under the Polaris
limited warranty policy . Polaris do es not recommend ope ration above

70 mph with this track.

NOTICE: High speed use on hard-packed surfaces is not recommended for

models equipped with a deep lug track. Track lug damage may occur.

snap back into the housing. Damage may result.

4. Repeat the cranking procedure as needed until the engine starts.

TIP:It may require as many as eight to ten pulls to prime the fuel system and

start the engine if the fuel tank has been completely emptied.

55

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 as outlined below. Oil added to the fuel and
oil injection systems will provide the necessary engine lubrication.

Tip: The semi-synthetic oil will seat the rings faster than the VES Gold Plus oil.

See page 104 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 Premium 2- Cycle Semi-Synthetic Oil
After Brea k-in: POLARIS VES Gold Plus Oil

Fuel Semi-Synthetic Oil Ratio

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

56

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 close-fit­ting 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 tank when refueling. See page 60.

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

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

Drive Belt Break-In

The break-in period for a new drive belt is 30 miles (48 km). During this
time, vary the throttle position under 50% and limit full throttle use.

New drive belts that feature a sanded finish should be first washed with
warm, soapy water and allowed to air dry prior to 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.

57

OPERATION

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.

Track Warm-Up

WARNING! A loose track or flying debris could cause serious 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 warming up the track. Do not use
excessive throttle during warm-up or when the track is free-hanging. Be sure the
rear support is stable.

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
approximately 4" (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 loop s and move them from side to side

to loosen snow and ice.

58

OPERATION

Fuel Safety

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
and water and change clothing.

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

The engine exhaust from this product contains chemicals known to cause can­cer, birth defects or other reproductive harm. Operate this vehicle only outdoors
or in well-ventilated areas.

WARNING

WARNING

59

OPERATION

Fuel

For peak performance, Polaris recommends the use of 91 octane or
higher fuel. Although 87 octane fuel is usable, some engine perfor­mance will be lost and fuel economy will decrease. Do not use lower
than 87 octane fuel. Do not use fuel containing more than 10% ethanol
(including E85).

NOTICE: Operating with obstructed fuel systems will result in serious engine

damage. Perform maintenance as recommended.
Damage to the fuel pump will occur if the snowmobile is operated with

an empty fuel tank. Do not allow the snowmobile to run out of fuel.
Always refuel when the level is low.

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

Fuel System Deicers

If you use non-oxygenated fuel, Polaris recommends the regular use of
isopropyl-based fuel system deicer. Add one to two ounces per gallon
(8-16 ml per liter) of gasoline to prevent engine damage resulting from
fuel system icing and lean fuel mixtures. Never use deicers or additives
containing methanol. Polaris also recommends the use of Carbon Clean
Plus. See page 104 for the part numbers of Polaris products.

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

OPERATION

n Oil
Low Oil Indicator Light

The low oil indicator light may flicker at times due to oil movement in
the bottle, but when the light comes on and remains on, add the recom­mended oil before further operation. See page 55 for oil recommenda­tions.

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 oil. Serious chemical reactions can cause injection
system blockage, resulting in serious engine damage. They 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.

Always maintain the oil level above the tank’s low level line. This is
especially important when the snowmobile 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.

NOTICE: Mixing brands or using a non-recommended oil may cause serious

engine damage. We recommend the use of POLARIS 2-cycle oils for
your snowmobile. Never mix brands.

Operating the snowmobile without proper engine lubrication can result
in serious engine damage. Always check the oil level when refueling.

Low Oil Level

Always do a visual check of the oil level when refueling. When the oil
reaches the low level mark, add the recommended oil to the tank.

The POLARIS oil cap on the oil bottle is vented to allow proper oil
flow. See your POLARIS dealer for recommended replacement parts.

Daily Storage

At the end of each ride, park the snowmobile
on a level surface and support it at the rear
with an appropriate track stand. The track
should be suspended approximately 4" (10 cm)
off the ground.

Remove the key and cover the snowmobile.

Towing

Do not use the front bumper to pull or drag the
snowmobile. The front bumper is not designed for this type o f use and
may detach from the vehicle if force is applied.

For your safety, do not attempt to use a tow hitch until you've read the
following warnings and understand the proper hitch functions.

WARNING! Objects towed with a rope have no braking power and can easily
collide with the rear of the snowmobile or other objects, resulting in seriou s
injury or death. DO NOT tow toboggans, sleds, saucers, or any type of vehicle
with a rope. Only a stiff metal pole connecting the towed object and the tow hitch
on the snowmobile should be used. If passengers are to be towed on a
toboggan or sled, make sure the pole is at least four feet (1.2 meters) long to
prevent any possibility of contact between the snowmobile's track and a person
riding in the towed object.

WARNING! Braking distances increase when towing loads. Slow down to
maintain control of the snowmobile.

If the snowmobile becomes inoperable and must be towed, and if it isn't
possible to use a rigid tow bar, attach the tow rope to the ski spindles
(not to the ski loops) to prevent damage to the steering components.
Remove the drive belt before towing, and have someon e ride on the
towed snowmobile to operate the brake and steering when necessary.

NOTICE: Towing a disabled snowmobile with the drive belt in place can result in

serious damage to the engine and drive system. Always remove the
drive belt from a disabled snowmobile before towing.

MAINTENANCE

Spark Plugs

Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine has been warmed up
and the vehicle has been driven at higher speeds. Immediately check the
spark plug for correct color.

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

Normal Spark 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.

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 Spark 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, use
of non-recommended injection oil, improper use of the choke, or incor­rect carburetor/throttle body adjustments.

77

MAINTENANCE

Spark Plugs

A new engine can cause temporary spark plug fouling due to the preser­vative added during the assembly process. Avoid prolonged idle speeds,
which cause plug fouling and carbo nization. Change the spark plugs
every 2000-2500 miles (3200-4000 km).

NOTICE: Using non-recommended spark plugs can result in serious engine

damage. A spark plug with a heat range too high will always cause
engine damage if the engine is operated in conditions more severe
than intended for that plug. Always use the spark plugs recommended
for your snowmobile. See your Owner’s Manual Supplement.

• Use recommended spark plugs with the proper gap.

• Use only resistor-type spark plugs.

• Torque spark plugs to 18-22 ft. lbs. (24-30 Nm).

• Always carry spare spark plugs.

Spark Plug Removal and Replacement

1. Remove the spark plug cap.

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

spark plug counterclockwise to remove it.

3. Reverse the procedure for spark plug installation.

4. Torque to specification.

5. Reinstall the spark plug cap.

78

MAINTENANCE

Intake Filters

The intake foam filter limits snow
ingestion into the intake system.
When operating in loose powder
snow, check the top of the foam
filter periodically to remove any

accumulation of snow.

NOTICE: Operating the snowmobile

with the intake filters
removed may cause intake
icing. The result will be poor
fuel economy or intake mal­function. Always reinstall
the intake filters before
operating the snowmobile.

Oil Lines

Inspect oil line condition at the intervals outlined in the Periodic Main­tenance Table beginning on page 69.

Oil Filter

Have your dealer change the oil filter
and bleed the system at the intervals
outlined in the Periodic Maintenance
Table beginning on page 69.

TIP:The direction of the arrows indicates

the direction of flow through the
filter.

Fuel Injectors

All fuel injector service must be performed by an authorized Polaris
dealer. Do not attempt to clean or service the fuel injectors.

Fuel Pump

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

Intake Foam Filters/Pre-filter

79

MAINTENANCE

Fuel Filter

See your Polaris dealer for replacement of the fuel filter at the intervals
outlined in the Periodic Maintenance Ta ble beginning on page 69.

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.

Fuel Lines

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.

NOTICE: Kinkin g 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.

Exhaust System

Check the exhaust system for wear or damage at the intervals outlined in
the Periodic Maintenance Table beginning on page 68.

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.

Always allow the engine and exhaust system to cool completely before
inspecting.

1. Open the hood and inspect the muffler and pipes for cracks or dam-

age.

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

grommets.

3. Check for loose clamps on the pipe covers.

80

MAINTENANCE

Cooling System

Coolant

The coolant supplied in the system is a 60/40 mixture of ethylene-glycol
and distilled water. This mixture provides protection against freezing.
Contact your dealer if greater protection is required.

Use Premium 60/40 anti-freeze coolant, which is already premixed and
ready to use. Do not dilute with water. Never exceed a 60% antifreeze/
40% water mixture. See page 104 for the part numbers of Polaris prod­ucts.

TIP:Never add tap water to the cooling system. Minerals cause deposits and

may react adversely with the metals in the engine and cooling system.

n Coolant Level

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

• Coolant bottle or overflow tank

• Filler neck

• Pressure cap

• Connecting hoses

Always maintain the coolant level between the minimum and maxim um
marks on the coolant bottle (when engine is cold) to prevent overheating
and serious engine damage.

NOTICE: Operating the snowmobile with insufficient coolant will result in over-

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

Cooling System

Coolant High Temperature Indicator Light

The high temperature indicator light will illuminate when engine cool­ant temperature becomes too hot for safe continued operation of the
engine. If you must drive your snowmobile after the high temperature
indicator light has come on, drive slowly and stop frequently to allow
the engine to cool down. Driving in deep snow will also help cool the
engine. See your dealer for service. Add coolant if the level is low.

TIP:Engine performance will be reduced if you continue operating when the

high temperature light is on.

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.

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 coola nt flow becomes re stricted or plugged, coolant loss, air lock or

engine damage may result. Most cooling systems are equipped with
a filter that should be periodically inspected or replaced.

Bleeding the Cooling System

Bleed the cooling system at the intervals outlined in the Periodic Main­tenance Table beginning on page 69. Perfo rm the bleeding procedure
when the engine is cold.

1. Remove the pressure cap and fill the coolant bottle with properly

mixed coolant to the maximum mark.

2. Elevate the front end of the machine slightly to aid in bleeding of

the heat exchangers.

3. 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.

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

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

Loosen the bleed screw occasionally to purge any trapped air.

6. Stop the engine and check the coolant bottle level. Fill as required.

7. Feel the heat exchangers under the running boards. If the system is

bled properly , they'll be warm to the to uch. If they're not, repeat step

5. Lift the front of the machine slightly to assist in the bleeding.

8. Replace the pressure cap and carefully lower the front end of the

machine.

n Hydraulic Brake Inspection

Inspect the brake lever travel before each use of the snowmobile. See
page 49.

Brake pads must be replaced when the brake pad material becomes thin­ner than the backing plate, approximately 1/16" (1.5mm). 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" (1.5mm).

nBrake Fluid

Replace brake fluid at least every two years with Polaris DOT 4 high
temperature brake fluid. See page 104 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.

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.

NOTICE: Brake fluid will damage decals, paint and some plastics. Always wipe

up spills immediately.

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 han dle 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 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" (.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 unsc rew 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 85.

8. Reinstall the gasket and cover.

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. Please see your Polaris dealer if you experience a decrease in
performance.

Clutch Center Distance

See your Owner's Manual Supplement for recommended center distance
for your machine. If adjustment is necessary, see your dealer.

89

MAINTENANCE

Clutch System

n Drive Belt Condition

Belt width and length must match the center distance of the clutches and
sheave width of the drive clutch. For this reason, Polaris recommends
that only O.E.M. belts be used. Other belts may match the dimensions,
but can drastically change the shift pattern, resulting in poor perfor­mance. See Drive Belt Troubleshooting on page 109.

Periodically check the condition and tension of the drive belt, and
always carry a spare. Inspect the belt for signs of excessive wear: frayed
edges, missing cogs, cracks and excessive looseness. Replace the belt if
any of these conditions exist.

TIP:A worn belt will continue to function, but will not deliver maximum

performance. Always carry a spare belt in case of an emergency.

For improved drive-away during extremely cold temperatures, remove
the belt and warm it to room temperature. Reinstall it before starting the
snowmobile.

Drive Belt Installation

1. Drop the drive belt over the drive

clutch and pull back the slack.
The belt cord line should be flush
with, or slightly above, the outer
circumference of the driven
clutch sheaves. The belt will seat
itself in the driven clutch during
the break-in period. Adjust the
belt ride-out after the break-in
period by readjusting belt deflec­tion.

TIP:To ensure satisfactory belt life, install belts so they operate in the same

direction of rotation by positioning the identification numbers so that you
can read them. If required, separate the sheaves as outlined in the belt
removal procedures.

2. Rotate the L-wrench counter-clockwise to tighten the sheaves while

working the belt to the outer edge of the sheaves.

3. Remove the wrench and store it in the tool kit.

4. Reinstall the side panel.

5. Close and secure the hood.

6. Break in the new belt. See page 56.

n Drive Belt Deflection

Measure belt deflection with both
clutches at rest and in their full
neutral position.

Place a straight edge on the belt
and apply downward pressure
while measuring at point A. This
measurement should be 1 1/4"
(3.2 cm).

Drive Belt Adjustment

1. Install the L-wrench into the open threaded hole in the outer sheave

of the clutch (see page 90). Turn the wrench clockwise slightly to
remove pressure from the sheaves.

2. Loosen the 7/ 16" jam nut.

3. Using a 1/8" Allen wrench, turn the set screw inward (clockwise) to

increase the distance between the sheaves or outward
(counterclockwise) to decrease the distance.

4. Tighten the jam nut. Store the L-wrench in the tool kit.

Torque Stop

Periodically check torque stop clear­ance. With clutches in proper align­ment, measure rear torque stop
clearance from the engine case. Rear
torque stop clearance should be .010"­.030" (.25-.75mm). Adjust if neces­sary. Secure the nut.

Track Replacement

When replacing the track, always install a track having the lug size rec­ommended for your model. See your Polaris dealer.

NOTICE: Installing tracks with larger lugs on machines equipped with coolers

will result in damage to the cooler or tunnel. Always install a track hav­ing the lug size recommended for your model.

Track Inspection

WARNING! Broken track rods can cause a rotating track to come off the
machine, which could cause serious injury or death. Never operate with a
damaged track. Never rotate a damaged track under power.

1. Using a hoist, safely lift and support the

rear of the snowmobile off the ground.

2. Rotate the track by hand to check for

damage.

3. Carefully examine the track along the

entire length of each rod. Bend the track
to check for breakage.

4. Replace the track if any rod damage is

found.

Track Lubrication

The slide rail needs snow for lubrication. Excessive wear indicates
insufficient lubrication. A new rail slide can cause faster heat build-up
in limited lubrication, resulting in excessive wear.

WARNING! Operating with insufficient lubrication between the rail slide and
track guide clips can cause track failure, loss of vehicle control and loss of
braking ability, which can result in serious injury or death. Avoid operating for
extended periods on ice and other surfaces that have little or no snow for
lubrication.

Track damage or failure caused by op eration on ice or under other poor
lubrication conditions will void the track warranty.

NOTICE: High speed use on hard-packed surfaces is not recommended for

models equipped with a deep lug track. Track lug damage may occur.
Keep high speed use to a minimum, including frequent slow-speed
intervals for track cooling.

MAINTENANCE

Track Tension

WARNING! Moving parts can cut and crush body parts. When performing the
checks and adjustments recommended on the following pages, stay clear of all
moving parts. Never perform track measurement or adjustments with the engine
running.

Track tension is critical for maximum efficiency and performance.
Track tension controls the approach angl e of the track to the rail beam in
powder snow conditions. Deep snow performance will be optimized at

the specified tension. Looser tensions will cause the track to “bunch” in
front of the rail tips, causing improper approach angle and poor perfor­mance. New tracks will need to be retightened and aligned after the first

ride.

TIP:Tension adjustments should be made only after the track is warmed up and

limber.

1. Turn the engine off.

2. Lift the rear of the snowmobile and safely support it off the ground.

3. Place the recommended weight or downward pressure on the track

at the specified distance (see chart) ahead of the center of the rear
idler wheel. Measure at the point where the weight is placed.

4. Check for specified slack between the wear surface of the track clip

and the plastic rail slide.

n Tr ack Alignment

Periodically check that the track is
centered and running evenly on the
slide rails. Misalignment will cause
excessive wear to the track and slide
rail.

1. Safely support the rear of the

snowmobile with the track off the
ground.

2. Start the engine and apply a small

amount of throttle until the track
turns slowly at least five
complete revolutions. Stop the
engine and let the track come to a
stop (do not apply brakes).

3. Inspect track alignment by looking through the track window to

make sure the rails are evenly spaced on each side. If the track runs
to the left, loosen the left locknut and tighten the left adjusting bolt.
If the track runs to the right, loosen the right locknut and tighten the
right adjusting bolt.

4. After adjustments are complete, tighten the locknuts and torque

idler shaft bolts to 35 ft. lbs. (47.5 Nm).

5. Repeat steps 2 and 3 to verify proper alignment.
