INTRODUCTION
IMPORTANT NOTES FOR OWNERS AND
DRIVERS
After reading this manual, store it in the snowmobile for convenient reference. It
should remain with the snowmobile when the snowmobile is sold.
Some of the illustrations and photos used in this manual are general
representations. Your model may differ.
Follow the maintenance program outlined in this manual. Preventive
maintenance ensures that critical components of the snowmobile are inspected
at specific mileage intervals. This service can be performed by your authorized
POLARIS dealer.
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.
PRESERVATION OF THE ENVIRONMENT
POLARIS is committed to supporting an environmental education campaign. We
encourage state and provincial governments across the snowbelt to adopt
rigorous safety training programs that encourage protection of our environment,
including wildlife and vegetation.
Snowmobile clubs and other organizations are working together to protect our
environment. Please support their efforts and operate your snowmobile with
consideration for the protection and preservation of our environment.

INTRODUCTION

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 levels of
two-stroke engines. We expect our efforts to lead to the reduction of potential air
pollution.
In addition to our technological research, we encourage government agencies,
manufacturers, distributors, dealers, ecologists, and other interested parties to
work together to develop data on environmental topics.

INTRODUCTION

SAFETY
OPERATOR SAFETY
Follow the recommended maintenance program in the Maintenance chapter of
this manual to ensure that all critical components on the snowmobile are
thoroughly inspected at specific mileage intervals. Your dealer can perform this
service.
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
aerodynamically unstable at speeds higher than those for which it is designed.
Loss of control may occur at higher speeds. Modifications may also create a
safety hazard and lead to bodily injury.
The warranty on your entire machine is terminated if any equipment has been
added, or any modifications have been made, to increase the speed or power
of the snowmobile.
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.
13
SAFETY

STAY CLEAR OF ENGINE
Never attempt adjustments with the engine running. Turn off the ignition, 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.
RIDER CAPACITY
This snowmobile is designed for a single rider only. Never carry a passenger on
this snowmobile.
14
SAFETY

RIDING APPAREL
HELMET
Wearing a helmet can prevent a severe head injury. Whenever riding this
POLARIS vehicle, always wear a helmet that meets or exceeds established
safety standards. Clasp the buckle and pull each strap tight to ensure the helmet
is properly secured to the head.
Parents should verify that young operators have a helmet that fits, and should
obtain one of proper size if it does not fit before allowing operation.
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. Whenever riding
a POLARIS vehicle, always wear shatterproof goggles or use a shatterproof
helmet face shield. POLARIS recommends wearing approved Personal
Protective Equipment (PPE) bearing markings such as VESC 8, V-8, Z87.1, or
CE. Make sure protective eye wear is kept clean.
15
SAFETY

CLOTHING
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.
Be prepared, be warm and be comfortable
when riding. Be aware of the weather
forecast, especially the windchill, and dress
accordingly. See page 29.
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 conditions you may encounter. Such
equipment may include, but is not limited to: extra clothing, a sleeping bag, a
flashlight, food and water, a signaling mirror, a means of building a fire, and a
two-way radio or cellular telephone.
Always carry the owner’s manual on your snowmobile. For added protection,
purchase and carry the following items on your snowmobile as well:
• Spare Drive Belt
• Extra Set of Spark Plugs
• Tow Rope
• Fuel Deicer
• Winter Survival Kit
• Trail Map
• First Aid Kit
• Tool Kit
16
SAFETY

EXCESSIVE SPEED
WARNING
High speed driving, especially at night, could result in serious injury or death.
Always reduce speed when driving at night or in inclement weather.
Always observe all state and local laws governing snowmobile operation and
speed limits. Always be alert and pay attention to the trail ahead. If your speed is
40 MPH (64 km/h), your snowmobile is traveling about 60 feet (18 m) per
second. If you look back for only two seconds, your snowmobile will travel about
120 feet (36 m). If your speed is 60 MPH (96 km/h), your snowmobile will travel
about 180 feet (55 m) in two seconds.
Traveling at night requires extra caution. Check headlight and taillight to ensure
proper operation, and don’t over-drive your headlight beam. Always be able to
bring your snowmobile to a stop in the distance illuminated by the headlight.
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 and bare roads limit the effectiveness of the
steering system. Look ahead, behind, and to both
sides before turning or crossing railroad tracks or
highways. Steep embankments may also hide your
view. Always leave yourself a way out.
Variances in snow depth and/or water currents may result in uneven ice
thickness. You may drown if you break through the ice. Never travel on frozen
bodies of water unless you have first verified that the ice is sufficiently thick to
support the weight and moving force of the snowmobile, you and your cargo,
together with any other vehicles in your party. Always check with local authorities
and residents to confirm ice conditions and thickness over your entire route.
Snowmobile operators assume all risk associated with ice conditions on frozen
bodies of water.
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.
17
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.
MOUNTAINOUS TERRAIN RIDING
Mountainous terrain operation, even for experienced riders, can present
conditions and situations that could result in serious injury or death. Please
review all of the information about riding in mountainous terrain on the following
pages of this manual.
WARNING
An avalanche can occur at any time, in any conditions and on any slope.
The avalanche information provided in this manual should be considered basic
information and is not intended to replace your participation in an avalanche
safety training course. After reviewing the avalanche information in this manual,
be sure to participate in an avalanche safety training course before riding in
