INTRODUCTION
Preservation of the Environment
Polaris is committed to supporting an environmental education
campaign. We encourage state and provincial governments across the
snowbelt to adopt rigorous safety training programs that encourage
protection of our environment, including wildlife and vegetation.
Snowmobile clubs and other organizations are working together to
protect our environment. Please support their efforts and operate your
snowmobile with consideration for the protection and preservation of
our environment.
Respect your snowmobile;
respect your environment;
and you will earn
the respect of everyone.
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
Vehicle Identification Numbers
The tunnel vehicle identification number (VIN) and engine serial
number are important for model identification when registering your
snowmobile, when obtaining insurance, and when ordering
replacement parts. In the event your snowmobile is stolen, these
numbers are essential to its recovery and identification.
Remove the spare key and store it in a safe place. Your key can be
duplicated only by mating a Polaris key blank with one of your
existing keys. If both keys are lost, the ignition switch must be
replaced. See your Polaris dealer.
NOTE: Record your snowmobile’s ID numbers and key number in the
spaces provided.

WARNING
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
recommend 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 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.

SAFETY
Operator Safety
Stay Away From Moving Parts
Be alert when riding, and remain properly seated to stay clear of the
track. Your snowmobile is propelled by a revolving track that must be
partially exposed for proper operation. Serious injuries may result if
hands, feet, or clothing become entangled in the track.
Never attempt adjustments with the engine running. Turn off the
ignition, raise the hood, make the adjustment, secure shields and
guards, secure the hood, and then restart the engine to check its
operation.
Never hold the snowmobile up or stand
behind it while warming up the track. A
loose track or flying debris could cause
serious personal injury or death.
We recommend having your dealer perform
track service and alignment procedures.
WARNING
If fingers or clothing contact the moving parts of an engine,
serious injury can result. Always stop the engine before
attempting adjustments.

SAFETY
Operator Safety
Riding Position
Operating a snowmobile requires skill and balance for proper control.
Rider positions may vary from person to person as each becomes more
skilled; but under most conditions, the proper position is to be seated
with feet on the running boards, and comfortably positioned for proper
throttle, brake, and steering control.
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.
For added protection, carry the following items on your snowmobile at
all times:
SSpare Drive Belt SExtra Set of Spark Plugs
STow Rope SExtra Oil
SFuel Deicer SWinter Survival Kit
STrail Map SOwner’s Manual
SFirst Aid Kit
Improper riding position may seriously reduce your ability to
control the machine and may result in serious injury or death.
Always be properly seated and in position to control your vehicle.
WARNING
Use of a backrest may hinder your weight shifting ability. This
could affect your ability to control this rider-active vehicle in
certain extreme driving situations.
WARNING

12
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.
Riding Apparel
Be aware of the weather forecast and
especially the wind chill. A wind chill
table is provided on page 21 for your
reference. To better enjoy your ride, be
prepared, be warm and be comfortable.
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.
Control becomes more difficult with two people on board. More
space is required to make turns, and longer distances are needed
for stopping. Make sure the passenger remains seated behind the
driver, facing forward, with both feet placed firmly on the running
boards. Slow down and avoid “jumping” your snowmobile.
WARNING
Loose clothing or long scarves may easily become entangled
in moving parts and cause serious personal injury.
Always wear an approved helmet and eye protection.
WARNING

13
SAFETY
Operator Safety
Excessive Speed
Observe all state and local laws governing snowmobile operation.
They’ve been established for your protection.
Always be alert and pay attention to the trail ahead. Multiplying speed
(MPH) by 1.5 will equal the approximate number of feet per second
your machine travels. If your speed is 40 MPH, your machine is
traveling about 60 feet per second. If you look back for only two
seconds, your machine will travel about 120 feet. If your speed is 60
MPH, your machine will travel about 180 feet 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
illuminated by the headlight.
Rider Capacities
Driving 1-Up - Some Polaris snowmobiles are designed for a single
rider only. A decal on the console of these models indicates single
rider operation.
Driving 2-Up - Some Polaris snowmobiles are designed for up to two
riders. A decal on the hood of these models indicates that the vehicle
is designed for one operator and one passenger only. See page 23 for
decal location.
Machines designed for two riders should never be operated with more
than two people on board. When traveling with a passenger, it’s the
driver’s responsibility to operate the machine safely.
Slow down! Control becomes more difficult with two people on board.
More space is required to make turns, and longer distances are
necessary for stopping.
High speed driving, especially at night, could result in serious
personal injury or death. Always reduce speed when driving at
night or in inclement weather.
WARNING

14
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
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. 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.

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.
Driving on Slippery Surfaces
Excessive shifting of operator body weight when turning on
hard-packed snow or ice may lead to loss of vehicle control and result
in serious injury or death. Slow down to maintain control under these
conditions.
It’s dangerous to drive on ice or other slippery surfaces. If it’s
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.
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.
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.
WARNING

16
SAFETY
Operator Safety
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.
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.
WARNING

17
SAFETY
Operator Safety
Driving Downhill
When riding downhill, shift your weight to the rear of the machine 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
machine and keep it from rolling freely downhill.
Clutch Guard
Do not operate the engine with the clutch guard removed.
The clutch guard is designed to protect the operator from metal parts if
the clutch should fail. Although the chance of failure is extremely
remote, don’t defeat the purpose of the guard by removing it. It’s
provided for your 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. Operation of the engine with the belt removed may
result in personal injury or damage to the engine.
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.
WARNING

18
SAFETY
Operator Safety
Intake Silencer
Do not operate the engine with the intake silencer or filter removed.
Damage to the engine may occur if the intake silencer or filter are
removed.
Clutches
Do not attempt to service the clutches.
All clutch service must be performed by your dealer. The clutch is a
complex mechanism that rotates at high speeds. Each clutch is
dynamically balanced before installation. Any tampering may disrupt
this precision balancing and create an unstable condition.
Cold Weather Drive-Away
Whenever your snowmobile has been parked for a length of time,
especially overnight, always make sure the skis and track are loosened
from ice and snow before attempting to drive. Apply the throttle with
enough authority to put the machine into motion, but always operate
within safety limits and, on 2-Up machines, with respect for a
passenger. See Starting a Cold Engine on page 56.
Maneuverability
Control and maneuverability comes not only through the steering and
skis, maximum control is achieved by shifting of body weight.
Maneuverability will change for lighter operators or machines designed
to carry a load or a passenger.
Maintenance
Your Polaris snowmobile is a well-engineered and well-constructed
recreational vehicle. Follow the recommended maintenance program
outlined beginning on page 73 of this manual to ensure that all critical
components on the snowmobile are thoroughly inspected by your
dealer at specific mileage intervals.
