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 69
of this manual to ensure that all critical components on the snowmobile
are thoroughly inspected by your dealer at specific mileage intervals.
Driving a snowmobile requires your full attention. DO NOT drink alcohol or use
drugs or medications before or while driving or riding as a passenger. They will
reduce your alertness and slow your reaction time.
Snowmobiles are capable of traveling at high speeds. Use extra caution to
ensure operator safety. Make sure your snowmobile is in excellent operating
condition at all times. Always check major and vital safety components before
every ride.
All POLARIS snowmobiles are designed and tested to provide safe operation
when used as directed. Failure of critical machine components may result from
operation with any modifications, especially those that increase speed or power.
DO NOT MODIFY YOUR MACHINE. The snowmobile may become 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.
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. Do not stand on the plastic flap.
WARNING! Serious injuries may result if
hands, feet, or clothing become entangled
in the track. Be alert when riding, and
remain properly seated to stay clear of the
track. Never hold the snowmobile up or
stand behind it while warming up the track.
A loose track or flying debris could cause
serious injury or death. We recommend
having your dealer perform all track service
and alignment procedures.
Stay Clear of Engine
Never attempt adjustments with the engine running. Turn off the 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
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. 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.

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
•TowRope •FirstAidKit
• 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.

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 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.

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.

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.
