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.
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.

SAFETY
Operator Safety
Follow the recommended maintenance program outlined beginning on
page 59 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
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 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. Stop the engine,
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.
Riding Position
Operating a snowmobile requires skill and balance for proper control.
Rider positions may vary with experience; but under most 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 be properly seated and in position
to control your vehicle.

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
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 19.
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.
Rider Capacity
Your Polaris snowmobile is designed for a single rider only. Do not
carry a passenger.
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. 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.
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.

12
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.

Avalanches
Snowmobilers should always be properly
trained and equipped before traveling in
mountainous terrain:
STake an avalanche class
STravel with experienced people
STravel on designated trails
SMake 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
mountainous terrain.
Before riding in mountainous terrain, call or log on to your local
avalanche advisory to get current weather and snow stability
information.
For more information about avalanche training and avalanche
conditions, contact local law enforcement in your area, or visit either
the American Avalanche Association online at
www.americanavalancheassociation.org or the U.S. Forest Service
National Avalanche Center 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
machine, 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.
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.
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.

15
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.
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 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.

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. 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.
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.
Maneuverability
While much control and maneuverability is achieved through the
steering system and skis, maximum control is achieved by the shifting
of your body weight. Maneuverability will change for lighter operators
or machines designed to carry a load.

17
SAFETY
Operator Safety
Inadequate Snow Conditions
WARNING
Do not drive for prolonged periods on blacktop, gravel, or ice.
Doing so could cause irreversible track damage and lead to
serious injury.
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 machine.
Driving in too little snow will result in excessive wear and damage to
the slide rail, track and/or engine.
If the machine becomes stuck in snow, clear the running board area of
snow, then step down the snow in front of the machine so that when
the throttle is opened, the snowmobile will be able to climb up and
over the snow.
CAUTION
When operating on icy surfaces or hard-packed snow, avoid
overheating the slide rail and track. Lack of lubrication and
cooling will cause overheating of the slide rail and track, resulting
in premature wear and failure. If frequently operating in low
cooling conditions, see your dealer for an optional wheel kit that
will reduce the wear from overheating.
