 INTRODUCTION
Important Notes for Owners and Drivers
After reading this manual, store it in the snowmobile for convenient ref-
erence. It should remain with the snowmobile when the snowmobile is
sold.
Some of the illustrations and photos used in this manual are general rep-
resentations. 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 cam-
paign. We encourage state and provincial governments across the snow-
belt 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 pro-
tect 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 stan-
dards. 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 manufac-
turing 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 reduc-
tion 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.

 SAFETY
Operator Safety
Follow the recommended maintenance program beginning on page 77
of this manual to ensure that all critical components on the snowmobile
are thoroughly inspected by your dealer at specific mileage intervals.
WARNING
Driving a snowmobile requires your full attention. DO NOT drink alcohol or use
drugs or medications before or while driving or riding as a passenger. They will
reduce your alertness and slow your reaction time.
Snowmobiles are capable of traveling at high speeds. Use extra caution to
ensure operator safety. Make sure your snowmobile is in excellent operating
condition at all times. Always check major and vital safety components before
every ride.
All POLARIS snowmobiles are designed and tested to provide safe operation
when used as directed. Failure of critical machine components may result from
operation with any modifications, especially those that increase speed or power.
DO NOT MODIFY YOUR MACHINE. The snowmobile may become aerody-
namically 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 haz-
ard 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 Clear of Track
Your snowmobile is propelled by a revolving track that must be partially
exposed for proper operation. Do not stand on the plastic flap.
WARNING! Serious injuries may result if
hands, feet, or clothing become entangled NO STEP
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 igni-
tion, open the side panels or hood, make the adjustment, secure shields
and guards, secure the side panels and hood, and then restart the engine
to check its operation.
WARNING! Serious injury can occur if fingers or clothing contact the moving
parts of an engine. Always stop the engine before attempting adjustments.

Riding Position
Operating a snowmobile requires skill and balance for proper control.
Rider positions may vary with experience and the features available on
some snowmobiles, but under many conditions, the proper position is to
be seated with both feet on the running boards and both hands on the
handlebar grips for proper throttle, brake and steering control.
WARNING! Improper riding position may reduce control and could result in
serious injury or death. Always ride in a position that allows for control of your
vehicle.

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 estab-
lished safety standards.
Approved helmets in the USA and Canada bear a U.S. Department of
Transportation (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 E4
distinguishing number of the country which has 051039
granted approval. The approval number and serial 0006.31
number will also be displayed on the label.
Eye Protection
Do not depend on eyeglasses or sunglasses for eye protection. When-
ever 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 com-
fortable when riding. Be aware of
the weather forecast, especially the
windchill, and dress accordingly.
See the chart on page 20.
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.

SAFETY
Operator Safety
Disabled Operators
Safe operation of this rider-active vehicle requires good judgement and
physical skills. Operators with cognitive or physical disabilities have an
increased risk of loss of control, which could result in serious injury or
death.
Survival Preparation
For your safety, always ride in a group of other snowmobilers. Always
tell someone where you're going and how long you expect to be gone. If
it isn't possible to ride with others, and you must travel into remote
areas, always carry survival equipment that's appropriate to the condi-
tions you may encounter. Such equipment may include, but is not lim-
ited 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 cel-
lular telephone.
Always carry the owner’s manual on your snowmobile. For added pro-
tection, 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

Rider Capacity
This snowmobile is designed for a single rider only. Never carry a pas-
senger on this snowmobile.
Excessive Speed
WARNING! High speed driving, especially at night, could result in serious injury
or death. Always reduce speed when driving at night or in inclement weather.
Always observe all state and local laws governing snowmobile opera-
tion 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 illu-
minated by the headlight.

13
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 R R
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 suffi-
ciently 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 condi-
tions and thickness over your entire route. Snowmobile operators
assume all risk associated with ice conditions on frozen bodies of water.
When teaching inexperienced operators to ride, set up a predetermined
course for practice. Make sure they know how to drive and control the
snowmobile before allowing them to make longer trips. Teach them
proper snowmobile courtesy, and enroll them in driver's training and
safety courses.

 SAFETY
Operator Safety
Avalanches
Snowmobilers should always be properly
trained and equipped before traveling in
mountainous terrain:
• Take an avalanche class
• Travel with experienced people
• Travel on designated trails
• Make sure each person is equipped
with a shovel, probe and avalanche
beacon.
You don't have to be snowmobiling on a slope for an avalanche to occur.
Be aware that all of the snow is connected. You may be riding on a flat
slope or snow covered road, but if the snowpack above is unstable
enough you can trigger an avalanche on a steeper slope above you.
Always be aware of snow conditions above you as you travel in moun-
tainous terrain.
Before riding in mountainous terrain, call or log on to your local ava-
lanche advisory to get current weather and snow stability information.
For more information about avalanche training and avalanche condi-
tions, contact local law enforcement in your area, or visit the American
and Canadian online avalanche centers at www.avalanche.org.

15
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 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. Slow down and use extra caution when
operating on slippery surfaces.

Inadequate Snow Conditions

Since snow provides the only lubrication for the power slide suspension
and, on liquid cooled models, cooling for the engine, adequate snow
cover is a requirement for operation of your snowmobile.
NOTICE: Driving in too little snow will result in excessive wear and damage to
the slide rail, track and/or engine.
WARNING! Inadequate cooling and lubrication will lead to overheating of the
slide rail and track, causing premature wear, damage and failure, which can
result in serious injury. Reduce speeds and frequently drive into fresh snow to
allow adequate cooling and polishing of the slide rail and track surfaces. Avoid
operating for prolonged periods on ice, hard-packed surfaces or roads.

Operating in Deep Snow

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

16
 SAFETY
Operator Safety
Driving Downhill
When riding downhill, shift your weight to the rear of the snowmobile
and reduce your speed to a minimum. Apply just enough throttle to keep
the clutch engaged, allowing the engine's compression to help slow the
snowmobile and keep it from rolling freely downhill.
WARNING! When driving on long downhill stretches, pump the brakes. Riding
the brakes may cause the brake system to overheat, which may result in brake
failure. Excessive or repetitive use of the brakes for high speed stops will also
cause an overheated brake system. This condition may lead to a sudden loss of
brakes and/or fire and may result in serious injury or death.

Driving in Hilly Terrain

WARNING! Climbing a hill or crossing the face of a slope may result in loss of
balance and snowmobile rollover, causing serious injury or death. Use caution
and good judgement when driving in hilly terrain.
Use extra caution when operating in hilly terrain. If climbing a hill is
unavoidable, keep your weight low and forward. If you must cross the
face of a slope, keep your weight on the uphill side of the snowmobile to
maintain proper balance and avoid possible roll-over.
Slow down when reaching the crest of a hill. Be prepared to react to
obstacles, sharp drops or other people or vehicles that may be on the
other side of the hill.
If you're unable to continue up a hill, turn the snowmobile downhill
before it loses momentum. If this isn't possible, spin the track just
enough to dig in to prevent it from rolling back down the hill. Stop the
engine and set the parking brake (if equipped). Keeping away from the
downhill side of the snowmobile, pull the rear of the snowmobile
around and point the front end and skis downhill. Remount the snowmo-
bile, restart the engine, release the parking brake, and descend the hill
carefully.

17
SAFETY
Operator Safety
Drive Belt
Do not operate the engine with the drive belt removed.
Any servicing that requires operation without a belt must be performed
by your dealer.
NOTICE: Operation of the engine with the belt removed may result in injury or
damage to the engine.

Intake Silencer
Do not operate the engine with the intake silencer or filter removed.
NOTICE: Damage to the engine may occur if the intake silencer or filter are
removed.

Clutches
Do not attempt to service the clutches.
All clutch service must be performed by your dealer. The clutch is a
complex mechanism that rotates at high speeds. Each clutch is dynami-
cally balanced before installation. Any tampering may disrupt this preci-
sion balancing and create an unstable condition.
Cold Weather Drive-Away
Whenever your snowmobile has been parked for a length of time, espe-
cially overnight, always make sure the skis and track are loosened from
ice and snow before attempting to drive. Apply the throttle with enough
authority to put the snowmobile into motion, but always operate within
safety limits.
Maneuverability
While much control and maneuverability is achieved through the steer-
ing 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.

18
 SAFETY
Operator Safety
Driving Responsibly
Every snowmobile handles differently, and even the most docile condi-
tions may become dangerous if operators drive improperly. If you're
new to snowmobiling, acquaint yourself with the snowmobile and with
what it will and won't do under various conditions. Even seasoned driv-
ers should spend some time getting the feel for a snowmobile before
attempting ambitious maneuvers.
• A snowmobile depends on the rider's body position for proper bal-
ance 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 snow-
mobile safety course and have an operator's certificate. For their pro-
tection, 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 pro-
tection 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 defen-
sively to avoid accidents.
• Remove the key from the ignition when you leave the snowmobile
unattended.

Operation Warning
• 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 reduced. Reduce speed and
allow extra space to turn or stop.
• To maintain vehicle control on ice or hard-packed surfaces, you
should have a proper balance of ski carbides to track 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.
• Before starting engine, check throttle, brake, and steering for proper
operation. Make sure hood and side panels are latched. Be seated
and in position to control the vehicle.
Oil injection system: Use unmixed fuel only. Check oil level when
refueling.

Whenever using ethanol, MTBE or other forms of oxygenated gaso-
lines, the fuel type designation setting must be changed to “Eth” in the
gauge. When using the recommended 91 non-ethanol gasoline, always
select the “91-non” setting.
Whenever in doubt of your fuel
purchase, use the “Eth” setting as
a safeguard.
Use the following procedure to
change the fuel type designation in
the gauge. Refer to the fuel type
selection label located inside the
left side panel.
1. Start the engine.
2. Lock the parking brake.

FEATURES
Detonation Elimination Technology (DET)
The DET system prevents damage to the engine from detonation by
going into an engine protection mode whenever the DET system is
active.
When excessive detonation is detected,
the check engine light will illuminate and
you may notice decreased engine perfor-
mance and RPM when the DET system is
activated. In most cases this is temporary
and the operator does not need to take
any action. The engine will return to its
normal performance automatically.
If severe detonation occurs, the check engine light will begin to flash
steadily and the gauge indicator will read “dET” (see illustration). The
engine will enter a limp home mode and RPM will be limited to 6500
RPM. The engine will remain in this mode until it is shut down and
restarted.

Suspension Adjustments
Factory settings, combined with user adjustments to the rear track shock
spring (RTSS), should be all that’s necessary to provide the best riding
experience for most riders. The primary adjustment for overall vehicle
balance is RTSS preload. Perform this adjustment first.
Always perform shock spring preload adjustments with the weight of
the vehicle removed from the shock and with the shock at full extension.
NOTICE: Never adjust spring preload to an installed length longer than the
maximum or shorter than the minimum lengths in the following chart.
Damage to the suspension could result. Never exceed one inch (2.54
cm) of preload beyond the factory settings. When decreasing preload,
make sure at least two turns of preload are holding the retainer
against the spring.

Suspension Adjustments
Fine-Tuning Your Suspension Set-Up
The primary adjustment for overall vehicle balance is RTSS preload.
Adjust the factory-set preload to the recommended setting for your
weight and then test ride. Additional minor adjustments can then be
made to the spring preload to adjust the feel of the vehicle. Do not
exceed the minimum and maximum installed length requirements. See
page 50.
For more ski lift (transfer), reduce spring preload by increasing the
installed length. Rotate the spring 1-2 full turns counter-clockwise
(when viewed from bottom). This will enhance maneuverability, mak-
ing the snowmobile more “flickable” although it may hinder climbing
performance.
For less ski lift (transfer), increase spring preload by reducing the
installed length. Rotate the spring 1-2 full turns clockwise (when viewed
from bottom). This will improve climbing ability and rider control.
To control the overall balance of the vehicle use the following guideline:
• More rear track shock spring preload increases ski pressure. Less pre-
load decreases ski pressure.
• Spring preload can affect bottoming resistance. More preload means
less bottoming. Less preload means a softer ride (and more bottom-
ing). Both adjustments will affect overall balance and ski pressure.
After adjusting RTSS preload to your satisfaction, the front track shock
(FTS) spring preload and independent front suspension (IFS) spring pre-
load can also be adjusted. See page 54.

Suspension Adjustments
Shock Compression Damping (RMK/ASSAULT RMK)
The primary adjustment for overall vehicle balance is RTSS preload.
Perform this adjustment first. See page 50. After adjusting RTSS pre-
load to your satisfaction, compression damping adjustments can be
made to control ride quality and bottoming resistance.
800 RMK Damping
Screw
Make the adjustments in half-turn incre-
ments, then test ride.
To stop bottoming, turn the damping
screw clockwise one half-turn, then test
ride. Repeat the adjustment until bottom-
ing stops and the desired ride quality is
achieved.
ASSAULT RMK Damping
Compression damping can be adjusted at Stiffer Softer
the front suspension and at the rear track
shock. Make adjustments in 2-click incre-
ments, then test ride. When adjusting the
front suspension, always adjust both
clickers equally.
To stop bottoming of the front or rear sus-
pension (stiffer ride), rotate the clicker(s)
clockwise two clicks (as viewed from the
top of the clicker), then test ride. Repeat
the adjustment until bottoming stops and
the desired ride quality is achieved.
For a more plush ride at the front or rear
Sti

suspension, rotate the clicker(s) counter-

ff
er

clockwise two clicks, then test ride.

Repeat the adjustment until the desired
ride quality is achieved.

Suspension Adjustments
Independent Front Suspension and Front Track Shock
Spring Preload (RMK/PRO-RMK)
Factory settings, combined with user adjustments to the rear track shock
spring, should be all that’s necessary to provide the best riding experi-
ence for most riders. The primary adjustment for overall vehicle balance
is RTSS preload. Perform this adjustment first. See page 50.
After adjusting the preload, and if desired, additional adjustments can be
made to the independent front suspension and front track shock preload.
When adjusting the front suspension, be sure the springs on both sides
of the vehicle are at the same adjustment.
Always perform shock spring preload adjustments with the weight of
the vehicle removed from the shock and with the shock at full extension.
NOTICE: Never exceed one inch (2.54 cm) of preload beyond the factory set-
tings. When decreasing preload, make sure at least two turns of pre-
load are holding the retainer against the spring.
For a softer ride on rough, washboard surfaces, reduce front track shock
(FTS) spring preload by 1-2 turns.
To improve corner stability, increase front suspension (IFS) spring pre-
load by 1-2 turns on both sides of the vehicle.
NOTICE: IFS spring installed length must always be set at least 1/4 inch (6 mm)
less than the free length.

Steering System
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.
Track
Track damage or failure caused by operation on ice or poor lubrication
conditions voids the track warranty.
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 the vehicle.
WARNING! 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.

Hood and Side Panel Fasteners

OPERATION
Break-In Period
Engine Break-In
Always follow these recommended break-in procedures for new or
rebuilt engines. The first tank of fuel is considered the break-in period
for the engine.
Premix the first tank of fuel and fill the oil reservoir as outlined below.
Oil added to the fuel and oil injection systems will provide the necessary
engine lubrication.

Oil Recommendations
First Tank of Fuel: POLARIS VES Gold Plus 2-Cycle Oil
After Break-in: POLARIS VES Gold Plus 2-Cycle Oil

See page 116 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.
Fuel VES Gold Plus Oil Ratio
Each 5 gal. (19 l) 16 oz. (473 ml) 40:1

 OPERATION
Break-In Period
Engine Break-In
Excessive heat build-up during the first three hours of operation will
damage close-fitted engine parts. Do not operate at full throttle or high
speeds for extended periods during the first three hours of use. Vary the
throttle openings and vehicle speeds to reduce friction on all close-fit-
ting 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 snow-
mobile.
Oil Injection System
Always check and fill the oil bottle when refueling. See page 69.
NOTICE: Serious engine damage can occur without the proper lubrication.
Check the oil bottle level often during the first tank of fuel. If the oil
level doesn't go down, contact your dealer immediately.

Drive Belt/QUICKDRIVE Belt Break-In

The length of the break-in period varies depending on the type of drive
system. The break-in period for a new drive belt is 30 miles (48 km).
The break-in period for a new QUICKDRIVE belt is 100 miles (160
km).
• During the break-in period, vary the throttle position under 50% and
limit full throttle use.
• Always take time to warm up the belt and driveline prior to operating
the snowmobile. Free the track and skis from the ground before
engaging throttle.
QUICKDRIVE Belt
During the 100 miles (160 km) of belt break-in, the rider will hear a
sound made by the drive system. After the break-in period, the sound
will become similar to that of a traditional chaincase.
During the break-in period, this belt will shed a fiber-type material in
and around the drive system. Use a dry shop towel to clean the residue.

65
OPERATION
Track Warm-Up
WARNING! A loose track or flying debris could cause serious injury or death.
Stand clear of the front of the snowmobile and the moving track. Never hold the
snowmobile up or stand behind it while warming up the track. Do not use
excessive throttle during warm-up or when the track is free-hanging. Use a
stable rear support.
WARNING! Use of traction products such as studs, ice growsers, etc. will
increase the possibility of track damage and/or failure. This could cause loss of
control, resulting in serious injury or death. Always inspect for track damage
before operating the snowmobile.
Follow these steps to ensure proper warm-up of the engine, drive train
and track.
1. Use an appropriate stand to securely support the rear of the snow-
mobile at the rear bumper. The track should be about 4 inches (10
cm) off the ground.
2. Start the engine and allow it to warm up two to three minutes.
3. Depress the throttle abruptly and allow the track to rotate several
revolutions.
TIP: It will take longer to warm up the track sufficiently during colder outdoor
temperatures.
4. Release the throttle, apply the brakes, shut off the engine and lower
the snowmobile to the ground.
5. Grasp the skis by their front loops and move them from side to side
to loosen snow and ice.
Slide Rail and Track Cooling
NOTICE: Inadequate cooling and lubrication will lead to overheating of the slide
rail and track, resulting in premature wear and failure. Reduce speeds
and frequently drive into fresh snow to allow adequate cooling and
polishing of the slide rail and track surfaces. Avoid operating on ice,
hard-packed surfaces or roads.

OPERATION
Fuel Recommendation
For peak performance, POLARIS recommends the use of 91 octane fuel
or higher, with no ethanol. 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. Never use E85 fuel in your snowmobile.
NOTICE: Operating with obstructed fuel systems will result in serious engine
damage. Perform maintenance as recommended.
Prolonged exposure to petroleum based products may damage paint.
Always protect painted surfaces when handling fuel.

Fuel System Deicers

If you use non-ethanol fuel (sometimes labeled “non-oxygenated”),
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 damage resulting from fuel system icing. Never use deicers
or additives containing methanol. POLARIS recommends the use of
Carbon Clean Plus. See page 116 for the part numbers of POLARIS
products.
If you use fuel with up to 10% ethanol (sometimes labeled “oxygen-
ated”) do not add deicers or additives that contain any form of alcohol.

port it at the rear with an appropriate track stand. The track should be
suspended approximately 4 inches (10 cm) off the ground.
Remove the key and cover the snowmobile.
Towing
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 serious
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 someone 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

 MAINTENANCE
Intake Filters
The intake foam filters
limit snow ingestion into
the intake system. When
operating in loose powder Intake
snow, check the foam fil- Filters
ters periodically to
remove any accumula-
tion of snow.
Fuel Pump
All fuel pump service must be performed by an authorized POLARIS
dealer. Do not attempt to service the fuel pump.
Fuel Filter/Fuel Lines
See your POLARIS dealer for replacement of the fuel filter at the inter-
vals outlined in the Periodic Maintenance Table beginning on page 78.
Contaminated or poor quality fuel will shorten the life of the fuel filter
and result in poor engine performance. Always store fuel in clean fuel
containers. If low fuel pressure or reduced engine performance occurs
between the recommended fuel filter service intervals, the filter may
need replacement. See your dealer.
Inspect the fuel lines regularly for signs of deterioration or damage.
Always check fuel line condition after periods of storage. Normal dete-
rioration from weather and fuel compounds may occur. Replace worn or
damaged fuel lines promptly.
NOTICE: Kinking the fuel lines or using a pliers or similar tools to remove fuel
lines may cause damage to the lines. If a fuel line has been damaged
or kinked, replace it promptly.

85
MAINTENANCE
Spark Plugs
Spark Plug Recommendations
A new engine can cause temporary spark plug fouling due to the preser-
vative added during the assembly process. Avoid prolonged idle speeds,
which cause plug fouling and carbonization.
Refer to the specifications section for the specific spark plug to be used
in your snowmobile.
Change the spark plugs at the intervals outlined in the Periodic Mainte-
nance Table beginning on page 77.
• 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.
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.

86
 MAINTENANCE
Spark Plugs
Spark Plug Inspection
Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine has been warmed up
and the vehicle has been driven at higher speeds. Immediately check the
spark plug for correct color.
CAUTION! A hot exhaust system and engine can cause burns. Wear
protective gloves when removing a spark plug for inspection.
1. Remove the left side panel.
2. Remove the spark plug cap.
3. Using the special wrench provided in the tool pouch, rotate the
spark plug counter-clockwise to remove.
4. Reverse the procedure for spark plug installation. Torque to specifi-
cation.
5. Reinstall the spark plug cap.
Spark Plug Condition
Normal Plug
The normal insulator tip is gray, tan or light brown. There will be few
combustion deposits. The electrodes are not burned or eroded. This indi-
cates the proper type and heat range for the engine and the service.
TIP: The tip should not be white. A white insulator tip indicates overheating,
caused by use of an improper spark plug or incorrect carburetor/throttle
body adjustments.
Wet Fouled Plug
The wet fouled insulator tip is black. A damp oil film covers the firing
end. There may be a carbon layer over the entire nose. Generally, the
electrodes are not worn. General causes of fouling are excessive oil or
use of non-recommended injection oil.

87
MAINTENANCE
Oil Lines
Inspect oil line condition every 1000 miles (1600 km) as outlined in the
maintenance charts beginning on page 77.
Oil Filter
Please see your dealer for replacement of the in-line oil filter every 2000
miles (3200 km) as outlined in the maintenance charts beginning on
page 77.

88
 MAINTENANCE
Cooling System
Coolant
The coolant supplied in the system at the factory is a 50/50 mixture of
ethylene-glycol and distilled water, which will provide adequate freeze
protection under most conditions. If the vehicle will be stored or oper-
ated at extremely low temperatures, greater protection may be required.
Please see your POLARIS dealer.
When adding or changing coolant, POLARIS recommends using Pre-
mium 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 116 for POLARIS products.
Never add tap water to the cooling system. Minerals cause deposits and
may react adversely with the metals in the engine and cooling system.
Coolant Level
The engine coolant level is controlled by the recovery system. The
recovery system components are:
• Coolant bottle/overflow tank
• Pressure cap
• Connecting hoses
Always maintain the coolant level at or “Full Cold” Mark
slightly above the FULL COLD mark on
the coolant bottle (when the engine is
cold).
1. Stop the engine.
2. Open the right side panel.
3. View the coolant level in the coolant
bottle.
4. Add coolant as needed.
NOTICE: Operating the snowmobile with insufficient coolant will result in over-
heating and serious engine damage. Always maintain the coolant
level as recommended.

89
MAINTENANCE
Cooling System
Engine Overheating
The over-temperature indicator on the
instrument cluster will illuminate when the
engine is overheating. The indicator will
flash when engine temperature reaches
critical levels.
Illuminated Indicator
Take action to cool the engine:
• Drive in loose snow.
• View the coolant level. Do not open the
pressure cap while the engine is hot.
Add coolant if the level is low.
• Stop the engine and allow it to cool down.
If you must continue to operate while the indicator light is illuminated,
drive slowly and stop the engine frequently to allow it to cool down.
Flashing Indicator
If the indicator flashes, continued operation could result in serious
engine damage. The system will automatically reduce engine power and
create a misfire condition. Stop the engine immediately. Allow the
engine to cool down.
If engine overheating seems to be caused by something other than poor
cooling conditions, see your dealer for service.
Flushing the Cooling System
To ensure that the coolant maintains its ability to protect the engine,
drain the system completely every two years and add a fresh mixture of
antifreeze and distilled water. This service must be performed when the
engine is cold. Ask your POLARIS dealer to check the coolant when he
performs the fall tune-up on your snowmobile.

90
 MAINTENANCE
Cooling System
Bleeding the Cooling System
CAUTION! Steam and hot liquids will cause burns to your skin. Never bleed the
cooling system or remove the pressure cap when the engine is warm or hot.
Use of a non-standard pressure cap will not allow the recovery system to
function properly. If the pressure cap needs replacement, contact your
dealer for the correct part.
NOTICE: If coolant flow becomes restricted or plugged, coolant loss, air lock or
engine damage may result.
1. Position the vehicle so that the top of the tunnel is level. Elevate the
front of the vehicle slightly if necessary.
2. Make sure the engine is cold before continuing.
3. Remove the right side panel.
4. Fill the coolant bottle with properly mixed coolant to the maximum
mark. Do not install the pressure cap at this time.
5. Remove the bleed screw from the water outlet manifold and/or the
thermostat housing. Allow the coolant to bleed through the system
until it runs out the bleed holes. Reinstall the bleed screw into the
manifold.
6. Add coolant to the coolant bottle to the maximum mark.
7. Reinstall the side panel. Always ensure that the hood and side pan-
els are securely in place before starting the engine.
8. Start the engine and run at a fast idle for two to three minutes.
Loosen the bleed screw occasionally to purge any trapped air.
9. Stop the engine and check the coolant bottle level. Add coolant as
needed. Reinstall the side panel.
10. Carefully and briefly touch the top of the tunnel cooler under the
seat. If the system is bled properly, the cooler will be warm to the
touch. If not, repeat step 8. Lift the front of the snowmobile slightly
to assist in the bleeding.

Brakes
Hydraulic Brake Inspection
Inspect the brake lever reserve before each use of the snowmobile. See
page 59.
Brake pads must be replaced when the brake pad material becomes thin-
ner than the backing plate (approximately 1/16 inch or 1.5 mm). A kit is
available for replacing brake pads. See your dealer.
WARNING! Brake failure during operation can result in serious injury or death.
Properly functioning brakes are vital to your safety. Be sure the brake pads do
not drag on the disc and that brake lever travel is not excessive. Always replace
brake pads when the brake pad material becomes thinner than the backing plate
(approximately 1/16 inch or 1.5 mm).

Excessive Lever Travel
Hydraulic brakes are self-adjust-
ing, but if excessive brake pad
clearance develops, bring the
snowmobile to an authorized
POLARIS dealer for inspection 2
and adjustment.
TIP: The PRO RMK and RMK ASSAULT models are equipped with a lightweight
brake disc that has vent holes. These holes may cause a high-pitched
sound during operation.

 MAINTENANCE
Brakes
Brake Fluid
The brake fluid level can be seen through a plastic sight glass in the
brake reservoir. If the fluid is sufficient, the sight glass will be black. If
the sight glass is any color other than black, add brake fluid.
Replace brake fluid at least every two years with POLARIS DOT 4 high
temperature brake fluid. See page 116 for the part numbers of POLARIS
products.
WARNING! After opening a bottle of brake fluid, always discard any unused
portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it
rapidly absorbs moisture from the air. The moisture causes the boiling
temperature of the brake fluid to drop, which can lead to early brake fade and
the possibility of accident or serious injury.
WARNING! Keep the master cylinder cover free of dirt and debris. The vent slits
allow for diaphragm movement, and if they become plugged, movement of
brake fluid below the diaphragm may be restricted, altering brake function.
NOTICE: Brake fluid will damage labels, paint and some plastics. Always wipe
up spills immediately.

95
MAINTENANCE
Brakes
Bleeding the Hydraulic Brake System
Air in the hydraulic brake system will cause spongy brake lever action.
Bleed the system before operating the snowmobile.
WARNING! Operating the vehicle with a spongy brake lever can result in loss of
brakes, which could cause an accident and lead to serious injury or death.
Never operate the vehicle with a spongy-feeling brake lever.
During the bleeding procedure, keep the brake handle as level as possi-
ble. The reservoir must be in this position to minimize the possibility of
air entering the system through the reservoir vent.
1. Remove the brake master cylinder reservoir cover and gasket.
2. Fill the master cylinder reservoir to between the MIN and MAX
marks or 1/4-5/16 inch (.6-.8 cm) below the lip of the reservoir
opening. Reinstall the gasket and cover.
3. Slip a rubber tube over the ball of the bleeder valve and direct the
flow of fluid into an approved container.
4. Squeeze the brake lever a full stroke. Then unscrew the bleeder
valve 3/4 of a turn to release air.
5. Close the bleeder valve and release the brake lever.
6. Repeat steps 4 and 5 until fluid flows from the bleeder valve in a
solid stream free of air bubbles.
WARNING! Overfilling the master cylinder leaves no room for fluid expansion
and may cause the brakes to lock, resulting in serious injury or death. Always
add brake fluid to the fill line as recommended.
7. After bleeding is complete, refill the reservoir to the proper level.
See page 95.
8. Reinstall the gasket and cover.

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.
Rod
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.
If excessive rail slide wear occurs due to poor snow conditions, addi-
tional wheel kits are available. See your dealer for more information.
Track damage or failure caused by operation on ice or under other poor
lubrication conditions will void the track warranty.

Ski Alignment
WARNING! Improper ski alignment or adjustment may cause loss of steering
control, resulting in serious injury or death. Do not attempt to change the ski
alignment or camber adjustment. See your POLARIS dealer.

1. Place the handlebars in a straight-ahead position.

2. With only vehicle weight compressing the suspension, measure
10 inches (25.4 cm) forward from the center of the ski mounting
bolt. See illustration. At this point, measure between the skis. This is
measurement X.
3. Perform the same measurement rearward from the center of the ski
mounting bolt. This is measurement Y.
4. The X measurement should be 1/8-1/4 inch (3-6 mm) greater than
the Y measurement. If the skis are misaligned, see your dealer for
alignment correction as camber adjustment may also be affected.

Ski Skags
WARNING! Worn skis and/or skags will adversely affect handling. Loss of
vehicle control may result, causing serious injury or death. See your dealer's
studding chart for recommended skags. If you install longer or more aggressive
carbide skags than the original equipment, it may also be necessary to add track
studs to maintain proper vehicle control while turning on hard-packed snow or
ice.
Check skags before each use of the snowmobile to ensure positive steer-
ing characteristics. Skags must be replaced when worn to half their orig-
inal diameter.
TIP: Carbide skags must be replaced if any abnormal wear or chipping is found.

Skag Replacement
1. Raise and support the front of the
snowmobile so the skis are
approximately 6 inches (15.2 cm)
from the ground.
2. Remove the attaching nuts and pry
the skag downward.
3. Remove the front end of the skag.
4. Remove the rear end of the skag.

MAINTENANCE
Fall Tune-Up
For maximum performance, arrange for a fall service tune-up with your
POLARIS dealer. His experienced and trained service technician will
keep your snowmobile in peak operating condition.
Transporting the Snowmobile
Whenever the snowmobile is transported:
1. Be sure the fuel cap and oil cap are installed correctly.
2. Tie the snowmobile to the transporting unit securely using suitable
straps.
3. Remove the ignition key to prevent loss.
Extended Storage
Off-season or extended storage of your snowmobile requires preventive
measures to aid against deterioration and to prolong the useful life of
many components. See page 116 for the part numbers of POLARIS
products.
Cleaning and Preservation
Proper storage starts with cleaning, washing, and waxing the hood, side
panels, chassis, and plastic parts. Wipe down remaining surfaces with a
damp cloth. Clean and touch up with paint any rusted or previously
painted surfaces. Be sure that corrosive salt and acids are removed from
surfaces before beginning preservation with waxes and rust inhibitors
(grease, oil or paint).
The snowmobile should be stored in a dry garage or shed, out of direct
sunlight, and covered with a fabric snowmobile cover. Plastic tarp may
cause condensation to form and damage snowmobile components.

110
 MAINTENANCE
Extended Storage
Controls and Linkage
Lubricate all bushings and cables as outlined in the Periodic Mainte-
nance Table beginning on page 78.
Clutch and Drive System
Remove the drive belt and store in a cool dry location. Do not lubricate
clutch components, except the driven clutch shaft bushing as outlined in
the Master Repair Manual. See your dealer.
Engine Protection
Proper preparation of the engine and fuel system is vital to the preven-
tion of rust and corrosion on precision engine parts during storage.
Whenever the snowmobile is stored for a period of more than 60 days,
the engine must be fogged with fogging oil. Follow the engine fogging
instructions provided on the container.
Always add Premium Carbon Clean or a fuel conditioner/stabilizer to
the fuel tank. Follow the instructions on the container, running the
engine for five minutes to get additives through the entire fuel system.
Top off with fresh fuel. Do not allow the snowmobile to run out of fuel.
Electrical Connections
Replace worn or frayed electrical wire and connectors. Be sure wiring
harness is properly secured away from sharp edges, steering linkage,
moving parts, and hot exhaust parts.
Track and Suspension
Moderate track tension should be maintained during summer storage.
The snowmobile should be supported off the ground to allow the track
to hang freely.

WARRANTY
Limited Warranty
POLARIS Sales Inc., 2100 Highway 55, Medina, MN 55340, provides a ONE YEAR
LIMITED WARRANTY on all components of the POLARIS snowmobile against
defects in material or workmanship. This warranty covers the parts and labor charges for
repair or replacement of defective parts that are covered by this warranty. The warranty
begins on the date of purchase. This warranty is transferable to another consumer, dur-
ing the warranty period, through a POLARIS dealer.

Registration
At the time of sale, the Warranty Registration Form must be completed by your dealer
and submitted to POLARIS within ten days. Upon receipt of this registration, POLARIS
will record the registration for warranty. No verification of registration will be sent to
the purchaser as the copy of the Warranty Registration Form will be the warranty entitle-
ment. If you have not signed the original registration and received the customer copy,
please contact your dealer immediately. NO WARRANTY COVERAGE WILL BE
ALLOWED UNLESS THE SNOWMOBILE IS REGISTERED WITH POLARIS.
Initial dealer preparation and setup of your snowmobile is very important in ensuring
trouble-free operation. Purchasing a snowmobile in the crate or without proper dealer
setup will void your warranty coverage.

The warranty does not cover accidental damage, normal wear and tear, abuse or
improper handling. The warranty also does not cover any snowmobile that has been
structurally altered, neglected, improperly maintained, used for racing or used for pur-
poses other than for which it was manufactured. The warranty does not cover any dam-
ages that occur during trailer transit or as a result of unauthorized service or parts. In
addition, this warranty does not cover physical damage to paint or finish, stress cracks,
tearing or puncturing of upholstery material, corrosion or defects in parts, components
or the snowmobile due to fire, explosions or any other cause beyond POLARIS' control.
This warranty does not cover the use of unauthorized lubricants, chemicals, or fuels that
are not compatible with the snowmobile.
The exclusive remedy for breach of this warranty shall be, at POLARIS' exclusive
option, repair or replacement of any defective materials, or components or products.
THE REMEDIES SET FORTH IN THIS WARRANTY ARE THE ONLY REMEDIES
AVAILABLE TO ANY PERSON FOR BREACH OF THIS WARRANTY. POLARIS
SHALL HAVE NO LIABILITY TO ANY PERSON FOR INCIDENTAL, CONSE-
QUENTIAL OR SPECIAL DAMAGES OF ANY DESCRIPTION, WHETHER ARIS-
ING OUT OF EXPRESS OR IMPLIED WARRANTY OR ANY OTHER CONTRACT,
NEGLIGENCE, OR OTHER TORT OR OTHERWISE. THIS EXCLUSION OF CON-
SEQUENTIAL, INCIDENTAL, AND SPECIAL DAMAGES IS INDEPENDENT
FROM AND SHALL SURVIVE ANY FINDING THAT THE EXCLUSIVE REMEDY
FAILED OF ITS ESSENTIAL PURPOSE. Some states do not permit the exclusion or
limitation of incidental or consequential damages or implied warranties, so the above
limitations or exclusions may not apply to you if inconsistent with controlling state law.

122
 WARRANTY
Limitations of warranties and remedies
ALL IMPLIED WARRANTIES (INCLUDING BUT NOT LIMITED TO THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PAR-
TICULAR PURPOSE) ARE LIMITED IN DURATION TO THE ABOVE ONE YEAR
WARRANTY PERIOD. POLARIS FURTHER DISCLAIMS ALL EXPRESS WAR-
RANTIES NOT STATED IN THIS WARRANTY. Some states do not allow limitations
on how long an implied warranty lasts, so the above limitation may not apply to you if
inconsistent with controlling state law.

Promotional Warranties
Promotional warranties are sometimes offered by POLARIS. These warranties can be,
but are not limited to:
• Two-year extended engine coverage
• Two-year powertrain coverage
• Extended service contract
If you selected any type of extended warranty coverage as part of a POLARIS retail pro-
gram, please contact any authorized POLARIS dealer for additional information.

How to Obtain Warranty Service

If your snowmobile requires warranty service, you must take it to a POLARIS dealer
authorized to repair POLARIS snowmobiles. When requesting warranty service you
must present your copy of the Warranty Registration form to the dealer. (The cost of
transportation to and from the dealer is YOUR responsibility). POLARIS recommends
that you use your original selling dealer; however, you may use any POLARIS Servicing
Dealer to perform warranty service.
Please work with your dealer to resolve any warranty issues. Your dealer will contact the
appropriate personnel at POLARIS if additional assistance is needed.
This warranty gives you specific legal rights, and you may also have other rights which
vary from state to state.
If any of the above terms are void because of state or federal law, all other warranty
terms will remain in effect.

Engine Oil
1. Mixing oil brands or using non-recommended oil may cause engine damage. We rec-
ommend the use of POLARIS engine oil.
2. Damage resulting from the use of non-recommended lubricants may not be covered
by warranty.

123
WARRANTY
Conditions and Exclusions
In order to qualify for warranty, the product must have been properly set up and tested
by a POLARIS Dealer (if applicable). Failure of any dealer to perform the required vehi-
cle Pre-Delivery Inspection, perform all applicable service bulletins and have the con-
sumer sign the PDI form prior to delivery may void the warranty. Failure to provide
proof of required periodic maintenance upon request may result in denial of warranty
coverage. Use of the recommended POLARIS products for lubrication and maintenance
as directed by the Owner's manual is highly recommended. Should a failure occur dur-
ing the warranty period resulting from the use of non-recommended products, warranty
coverage may be denied.
Warranty does not apply to parts exposed to friction surfaces, stresses, environmental
conditions and/or contamination. The following items are excluded from warranty con-
sideration if the failure was due to wear or not the direct result of a defect:

Brake components Carburetor/Throttle body components
Seat components Engine components
Clutches and components Drive belts
Steering components Hydraulic components
Batteries Circuit breakers/Fuses
Light bulbs/Sealed beam lamps Electronic components
Idler wheels
Warranty applies to the product only and does not allow for coverage of personal loss.
Some items are considered "consumable," meaning they are considered part of normal
maintenance or part of completing an effective repair. The following items are excluded
from warranty coverage in the event of a warranty claim:
Spark Plugs Lubricants such as oil, grease, etc.
Filters Batteries (unless defective)
Fuel Cosmetic damage/repair
Sealants Coolants
Hotel fees Meals
Towing charges Shipping/ handling fees
Mileage Product pick-up/delivery
Rentals/Loss of product use Loss of vacation/personal time

RANTY OR SERVICE BULLETIN COVERAGE ON THIS VEHICLE IF IT IS SOLD
OUTSIDE THE COUNTRY OF THE SELLING DEALER'S AUTHORIZED LOCA-
TION.

POLARIS Industries. Dealers may not give authorization for export. You should consult
an authorized dealer to determine this vehicle's warranty or service bulletin coverage if
you have any questions.
This policy does not apply to vehicles registered to government officials or military per-
sonnel on assignment outside the country of the selling dealer's authorized location.
This policy does not apply to Safety Bulletins.

How to Get Service

In the Country where your vehicle was purchased:

you move or are traveling within the country where your vehicle was purchased, War-
ranty or Service Bulletin repairs may be requested from any authorized POLARIS dealer
who sells the same line as your vehicle.
Outside the Country where your vehicle was purchased:
If you are traveling temporarily outside the country where your vehicle was purchased,
you should take your vehicle to an authorized POLARIS dealer. You must show the
dealer photo identification from the country of the selling dealer's authorized location as
proof of residence. Upon residence verification, the servicing dealer will be authorized
to perform the warranty repair.

If you move to another country, be sure to contact POLARIS Customer Assistance and
the customs department of the destination country before you move. Vehicles importa-
tion rules vary considerably from country to country. You may be required to present
documentation of your move to POLARIS Industries in order to continue your warranty
coverage. You may also be required to obtain documentation from POLARIS Industries
in order to register your vehicle in your new country. You should warranty register your
vehicle at a local POLARIS dealer in your new country immediately after you move to
continue your warranty coverage and to ensure that you receive safety information and
notices regarding your vehicle.

125
WARRANTY
How to Get Service
If Purchased From A Private Party:
If you purchase a POLARIS product from a private citizen outside of the country in
which the vehicle was originally purchased, all warranty coverage will be denied. You
must nonetheless warranty register your vehicle under your name and address with a
local POLARIS dealer in your country to ensure that you receive safety information and
notices regarding your vehicle.

Notice
If your vehicle is registered outside of the country where it was purchased, and you have
not followed the procedure set out above, your vehicle will no longer be eligible for war-
ranty or service bulletin coverage of any kind, other than safety bulletins. (Vehicles reg-
istered to Government officials or military personnel on assignment outside of the
country where the vehicle was purchased will continue to be covered by the basic war-
ranty.)
For questions call POLARIS Customer Assistance (see page 121).

 WARRANTY
U.S.A. EPA Emissions Limited Warranty
This emissions limited warranty is in addition to the POLARIS standard limited war-
ranty for your vehicle. POLARIS Industries Inc. warrants that at the time it is first pur-
chased, this emissions-certified vehicle is designed, built and equipped so it conforms
with applicable U.S. Environmental Protection Agency emission regulations. POLARIS
warrants that the vehicle is free from defects in materials and workmanship that would
cause it to fail to meet these regulations.
The warranty period for this emissions-certified vehicle starts on the date the vehicle is
first purchased and continues for a period of 200 hours of engine operation, 4000 kilo-
meters (2485 miles) of vehicle travel, or 30 calendar months from the date of purchase,
whichever comes first.
This emissions limited warranty covers components whose failure increases the vehi-
cle’s regulated emissions, and it covers components of systems whose only purpose is to
control emissions. Repairing or replacing other components not covered by this war-
ranty is the responsibility of the vehicle owner. This emissions limited warranty does not
cover components whose failure does not increase the vehicle’s regulated emissions.
For exhaust emissions, emission-related components include any engine parts related to
the following systems:
• Air-induction system • Ignition system
• Fuel system • Exhaust gas recirculation systems
The following parts are also considered emission-related components for exhaust emis-
sions:
• Aftertreatment devices • Sensors
• Crankcase ventilation valves • Electronic control units
The following parts are considered emission-related components for evaporative emis-
sions:
• Fuel Tank • Vacuum Control Diaphragms*
• Fuel Cap • Control Cables*
• Fuel Line • Control Linkages*
• Fuel Line Fittings • Purge Valves
• Clamps* • Vapor Hoses
• Pressure Relief Valves* • Liquid/Vapor Separator
• Control Valves* • Carbon Canister

The exclusive remedy for breach of this limited warranty shall be, at the exclusive
option of POLARIS, repair or replacement of any defective materials, components or
products. THE REMEDIES SET FORTH IN THIS LIMITED WARRANTY ARE THE
ONLY REMEDIES AVAILABLE TO ANY PERSON FOR BREACH OF THIS WAR-
RANTY. POLARIS SHALL HAVE NO LIABILITY TO ANY PERSON FOR INCI-
DENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES OF ANY
DESCRIPTION,WHETHER ARISING OUT OF EXPRESS OR IMPLIED WAR-
RANTY OR ANY OTHER CONTRACT, NEGLIGENCE OR OTHER TORT OR
OTHERWISE. THIS EXCLUSION OF CONSEQUENTIAL, INCIDENTAL, AND
SPECIAL DAMAGES IS INDEPENDENT FROM AND SHALL SURVIVE ANY
FINDING THAT THE EXCLUSIVE REMEDY FAILED OF ITS ESSENTIAL PUR-
POSE.
ALL IMPLIED WARRANTIES (INCLUDING BUT NOT LIMITED TO ANY
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PAR-
TICULAR PURPOSE) ARE LIMITED IN DURATION TO THE WARRANTY
PERIOD DESCRIBED HEREIN. POLARIS DISCLAIMS ALL EXPRESS WARRAN-
TIES NOT STATED IN THIS WARRANTY. Some states do not allow limitations on
how long an implied warranty lasts, so the above limitation may not apply if it is incon-
sistent with the controlling state law.
This limited warranty excludes failures not caused by a defect in material or workman-
ship.This limited warranty does not cover damage due to accidents, abuse or improper
handling, maintenance or use. This limited warranty also does not cover any engine that
has been structurally altered, or when the vehicle has been used in racing competition.
This limited warranty also does not cover physical damage, corrosion or defects caused
by fire, explosions or other similar causes beyond the control of POLARIS.
Owners are responsible for performing the scheduled maintenance identified in the
owner's manual. POLARIS may deny warranty claims for failures that have been caused
by the owner’s or operator’s improper maintenance or use, by accidents for which
POLARIS has no responsibility, or by acts of God.
Any qualified repair shop or person may maintain, replace, or repair the emission con-
trol devices or systems on your vehicle. POLARIS recommends that you contact an
authorized POLARIS dealer to perform any service that may be necessary for your vehi-
cle. POLARIS also recommends that you use only Pure POLARIS parts. It is a potential
violation of the Clean Air Act if a part supplied by an aftermarket parts manufacturer
reduces the effectiveness of the vehicle's emission controls. Tampering with emission
controls is prohibited by federal law.
If you have any questions regarding your warranty rights and responsibilities, please
contact the POLARIS Warranty Department at 1-888-704-5290.
