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.
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.
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.
Some of the illustrations and photos used in this manual are general rep-
resentations. Your model may differ.

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 standards.
Our muffler systems are designed to reduce noise levels and must not be
altered or removed. The sound of your snowmobile may not be welcome
to non-snowmobilers, so you have a responsibility to operate your
snowmobile with concern for others. We do our part by manufacturing
quieter machines; we ask your help to further reduce the impact of noise
by operating your snowmobile safely and responsibly.
Air Pollution
Polaris engineers continuously investigate ways to reduce emission lev-
els of two-stroke engines. We expect our efforts to lead to the reduction
of potential air pollution.
In addition to our technological research, we encourage government
agencies, manufacturers, distributors, dealers, ecologists, and other
interested parties to work together to develop data on environmental
topics.

SAFETY
Operator Safety
Follow the recommended maintenance program beginning on page 65
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. They will reduce your alertness
and slow your reaction time. In most states and provinces, it’s prohibited by law
to drive while intoxicated or under the influence of drugs.
Polaris produces high performance snowmobiles capable of traveling at high
speeds. Extra caution must be observed to ensure operator safety. Make sure
your snowmobile is in excellent operating condition at all times. We strongly rec-
ommend that the operator check major and vital safety components before
every ride.
All Polaris snowmobiles are designed and tested to provide safe operation when
used as directed. Failure of critical machine components may result from opera-
tion with any modifications, especially those that increase speed or power. DO
NOT MODIFY YOUR MACHINE. The snowmobile may become aerodynami-
cally unstable at speeds higher than those for which it is designed. Loss of con-
trol 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 igni-
tion, 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.

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.
For added protection, carry the following items on your snowmobile at
all times:
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.

Riding Apparel
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
22.
WARNING! Avoid wearing loose
clothing or long scarves, which can
become entangled in moving parts
and cause serious injury.
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
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.

SAFETY
Operator Safety
Cargo Overload
Too much weight on the rear of the machine may reduce your ability to
steer. Do not exceed carrier and rack weight limits, and do not allow a
passenger to sit on the seat back or the cargo carrier.
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.
Excessive Speed
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 machine to a stop in the distance illumi-
nated by the headlight.
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.

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 machine will drown out
the sound of approaching vehicles. Look
ahead, behind, and to both sides before
turning or crossing railroad tracks or high-
ways. Steep embankments may also hide
your view. Always leave yourself a way
out.
Variances in snow depth and/or water currents may result in uneven ice
thickness. Always check with local residents or authorities for general
information on conditions when traveling on lakes and streams that are
strange to you. Before riding your machine on a frozen body of water,
be sure the ice is thick enough to support the machine and its operator,
as well as the force created by a moving vehicle. You may drown if you
and the snowmobile break through the ice.
When teaching inexperienced operators to ride, set up a predetermined
course for practice. Make sure they know how to drive and control the
snowmobile before allowing them to make longer trips. Teach them
proper snowmobile courtesy, and enroll them in driver’s training and
safety courses sponsored by local or state organizations.

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
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, check for ice and snow build-up that may be obstructing
the steering linkage. Snow screens and bib kits are available through
your dealer to help reduce snow and ice build-up.
WARNING! Ice and snow build-up may interfere with the steering of your
machine, resulting in serious injury or death. Keep the underhood area free of
snow and ice.
Driving on Slippery Surfaces
WARNING! Driving on ice or hard-packed snow reduces steering and braking
control, which may result in serious injury or death. Slow down and use caution.
If driving on ice or other slippery surfaces is unavoidable, use extreme
caution and operate at speeds no faster than a walk. Never attempt an
abrupt change of direction. The chance of “spin-out” increases under
these conditions.

17
SAFETY
Operator Safety
Driving in Hilly Terrain
WARNING! Climbing a hill or crossing the face of a slope may result in loss of
balance and machine roll-over, causing serious injury or death. Use caution and
good judgement when driving in hilly terrain.
Operating in hilly terrain requires extreme caution to maintain balance
and avoid roll-over. If climbing a hill is unavoidable, keep all your
weight low and forward.
If you must cross the face of a slope, keep your weight on the uphill side
of the machine to maintain proper balance and avoid possible roll-over.
Slow down when reaching the crest of a hill. Be prepared to react to
obstacles, sharp drops, or other people or vehicles that may be on the
other side of the hill.
If you’re unable to continue up a hill, turn the machine downhill before
it loses momentum. If this isn’t possible, spin the track just enough to
dig in to prevent it from rolling back down the hill. Stop the engine and
set the parking brake (if equipped). Keeping away from the downhill
side of the machine, pull the rear of the snowmobile around and point
the front end and skis downhill. Remount the machine, restart the
engine, release the parking brake, and descend the hill carefully.
