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 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 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.

INTRODUCTION

Vehicle Identification Numbers

Record your snowmobile’s identification numbers and key number in
the spaces provided below. The key number is stamped on the spare key.
The number on the rubber-coated key is in the form of raised dots.
Remove the spare key and store it in a safe place. An ignition key can be
duplicated only by ordering a Polaris key blank (using your key num­ber) and mating it with one of your existing keys. The ignition switch
must be replaced if all keys are lost.

SAFETY

Operator Safety

Follow the recommended maintenance program outlined beginning on
page 71 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. 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.

WARNING

Serious injury can occur if fingers or clothing contact the moving parts of an
engine. Always stop the engine before attempting adjustments.

10

SAFETY

Operator Safety

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.

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 • Winter Survival Kit

• Extra Set of Spark Plugs • Trail Map

•Tow Rope •First Aid Kit

• Extra Oil • Tool Kit

• Fuel Deicer

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 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. 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.

Clothing

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 21.

SAFETY

Operator Safety

Disabled Operators

Safe operation of this rider-active vehicle requires good judgement and
physical skills.

WARNING

Operators with cognitive or physical disabilities have an increased risk of loss
of control, which could result in serious injury or death. Do not allow disabled
persons to operate this vehicle.

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. 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.

13

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. Avoid travelling
on frozen bodies of water.

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 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 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 Downhill

When riding downhill, shift your weight to the rear of the snowmobile
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
snowmobile 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.

16

SAFETY

Operator Safety

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 in Hilly Terrain

WARNING

Climbing a hill or crossing the face of a slope may result in loss of balance
and snowmobile rollover, 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 snowmobile to
maintain proper balance and avoid possible rollover.

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 snowmobile 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 snowmobile, pull the rear of the snowmobile
around and point the front end and skis downhill. Remount the snowmo­bile, restart the engine, release the parking brake, and descend the hill
carefully.

17

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 snowmobile into motion, but always operate within
safety limits and, on 2-up machines, with respect for a passenger.

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
snowmobiles designed to carry a load or a passenger.

18

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 snowmobile. Driving in too
little snow will result in excessive wear and damage to the slide rail,
track and/or engine.

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.

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.

19

SAFETY

Operator Safety

Driving Responsibly

Every snowmobile handles differently, and even the most docile condi­tions may become dangerous if operators drive improperly. If you’re
new to snowmobiling, acquaint yourself with the machine and with
what it will and won’t do under various conditions. Even seasoned driv­ers should spend some time getting the feel for a machine before
attempting ambitious maneuvers.

• A snowmobile depends on the rider’s body position for proper bal­ance in executing turns, traversing hills, etc. Always start on a
smooth, level area to begin building your operating experience.

• Before allowing someone else to use your snowmobile, know the
extent of their operating skills. Check to see if they’ve taken a snow­mobile safety course and have an operator’s certificate. For their pro­tection, as well as yours, make sure they take a snowmobile safety
course. Everyone can benefit from the course.

• Don’t “jump” your snowmobile. Jumping may injure your back
because of spinal compression. The seat and suspension of your
snowmobile have been designed to provide protection under normal
riding conditions. Your snowmobile is not intended for this kind of
use.

• Be courteous to oncoming traffic by dimming your headlights and
reducing your speed.

• When traveling in a group of snowmobiles, don’t tailgate (follow too
closely). Leave enough distance between snowmobiles to provide
ample stopping room and to provide protection from flying snow and
debris. Allow even more distance when driving on slippery surfaces
or when driving in darkness or other low visibility conditions. Be
aware of any snowmobile traffic around your vehicle. Drive defen­sively to avoid accidents.

• Remove the key from the ignition when you leave the snowmobile
unattended.

SAFETY

Safety Decals and Locations

Operation Warning

(continued from previous page)

• Excessive speed, especially at night or with limited visibility, can
result in insufficient time for you to react to terrain changes, to
avoid unexpected obstacles, or to stop safely.

• Never consume alcohol or drugs before or while operating this vehi­cle.

• In an emergency, push down the Auxiliary Shut-Off Switch, located
on the top of the throttle control assembly, to stop the engine. Then
pull the brake lever to stop.

• Always wear an approved helmet, eye protection, and adequate
clothing while operating this vehicle.

• This vehicle is designed for adult use only. Check local laws for age
requirements.

• When operating with a passenger (on approved models only),
reduce speed and allow extra space for steering and stopping. A
passenger reduces your ability to control the vehicle.

• When operating on hard-packed snow, ice, or when crossing roads,
steering and braking ability are greatly reduced. Reduce speed and
allow extra space to turn or stop.

• To maintain vehicle control on ice or hard-packed surfaces, you
should have a proper balance of ski carbides to track studs. See
Owner’s Manual for proper use of traction products.

• Repeated stops from high speed may cause fading or sudden loss
of braking ability.

• Parking brake may relax when used for long periods. Do not leave
brake engaged for more than five minutes.

• Before starting the engine, check throttle, brake, and steering for
proper operation. Make sure hood is latched. Be seated and in posi­tion to control the vehicle.

Oil injection system: Use unmixed fuel only. Check oil level when
refueling.

FEATURES

Detonation Elimination Technology (DET)

A detonation sensor monitors the engine and responds to detonation by
automatically reducing the engine timing and adding fuel. This results in
decreased engine RPM and performance.

DET Troubleshooting

Use this chart to determine causes and solutions for detonation. If none
of these conditions exists and the sensor remains activated, see your
Polaris dealer for diagnosis.

Possible Cause Solution

Poor quality fuel Replace with higher quality fuel

Improper engine modifications Do not modify the engine

Effect of DET

The DET system prevents damage to the engine from detonation while
developing the maximum power of the engine safely. If the system
senses detonation beyond a preset limit, it retards ignition timing and
adds fuel to reduce the detonation and prevent engine damage.

When the detonation returns to a permissible level, the system will
return spark and fuel to normal, allowing the engine to run at rated
power levels.

Sensor Fail-Safe

The DET includes a sensor fail-safe system to prevent the engine from
damage if the sensor fails, becomes disconnected or is unable to detect
detonation. The rider will experience a loss in power. The sensor must
be reconnected or repaired to regain full power.

NOTE: The check engine light will flash six times if the sensor fails or

becomes disconnected.

IQ Front Suspension Adjustments

Independent Front Suspension (IFS)

Break in the suspension for approximately 150 miles (240 km) before
making any fine-tuning adjustments.

Settings will vary from rider to rider, depending on rider weight, vehicle
speed, riding style, and trail conditions. We recommend starting with
factory settings and then customizing each adjustment individually to
suit rider preference. The snowmobile should be methodically tested,
one change at a time, under the same conditions (trail and snow condi­tions, vehicle speed, riding position, etc.) after each adjustment until the
best ride is achieved.

camber adjustment may also be affected.

Air Shocks

Walker Evans air shocks can be adjusted for preload and valving. Please
see your Polaris dealer for these adjustments.

Standard Shocks

The tension at which the shock coil spring is set is called spring preload.
For the best ride, the suspension should be adjusted to use the full travel
of the shocks with occasional light bottoming. To determine if your
machine is using full travel, push the jounce bumper down on the shock
rod until it contacts the body and test ride the machine. The bumper will
move up on the rod in relation to the amount of travel that was used dur­ing the ride. If the travel is full, the bumper will be seated at the top of
the rod.

THE PERFECT FIT

IQ Front Suspension Adjustments

Front Shock Spring Preload

(RMK Premium Only)

Increasing spring preload will
increase ski-to-ground pressure.
Decreasing spring preload will
decrease ski-to-ground pressure.
When adjusting, be sure the springs
on both the left and right sides of the
machine are at the same adjustment.

To increase front shock spring pre­load, grasp the spring and turn it to
the left. Turn it to the right to decrease
preload.

Increasing the spring preload too
much may adversely affect the han­dling of the snowmobile and the per­formance of the suspension. Never
exceed one inch of preload beyond
the factory settings, and ensure that
both sides are adjusted the same.
When decreasing preload, make sure
at least two turns of preload are hold­ing the spring between the retainer on
top of the shock and the threaded
spring preload adjuster nut on the
shock body.

Low Preload High Preload

Front Shock Springs

(Standard only)

The front springs can be changed if spring preload alone isn't sufficient
and further adjustment is desired to control suspension stiffness. See
your Polaris dealer for more information.

THE PERFECT FIT

Rear Suspension Adjustments

Rider weight, riding style, trail conditions, and vehicle speed all affect
suspension action.

Each rear suspension can be adjusted to suit rider preference and deliver
excellent performance for a given set of conditions. However, all sus­pension designs and adjustments involve a compromise, or trade-off.
For example, a suspension set up for snow-cross racing would provide a
very stiff ride on the trail. A suspension set up for trail riding would bot­tom out harshly on a snow-cross course.

Make adjustments to one area at a time so you can evaluate the change.
For further assistance, see your dealer.

Suspension Performance Tips

• Rider weight usually determines the position at which the spring pre-

load should be set. However, this may vary with riding style. With a
little experimentation, each rider can find a preferred set-up. These
adjustments are easy to make, involve very little time or effort, and
greatly affect the ride.

• In deep snow, a new rail slide will offer improved performance over a

worn slide. It can also improve top speed.

NOTE: Keep the suspension pivot points lubricated. This will reduce moisture

and rust build-up and ensure proper function of the suspension com­ponents. Grease rear suspension pivots before adjusting the rear sus­pension. Refer to the suspension lubrication information beginning on
page 76.

42

THE PERFECT FIT

Rear Suspension Adjustments

Initial Spring Preload Setting (Sag Method)

To set up the rear suspension torsion
spring preload, measure the distance
between the ground and rear bumper.
This is measurement X.

Take this measurement with no rider
and with the rear suspension at full
extension.

NOTE: The rear bumper may need to

be lifted upward slightly to fully
extend the suspension.

Next, have the rider drop down hard
on the seat and bounce up and down
several times, collapsing the rear
suspension. With the rider seated,
measure the distance between the
ground and the rear bumper at the
exact location used for measure­ment X. This is measurement Y.

To determine sag, commonly referred to as ride-in, subtract measure­ment Y from X (Sag=X-Y). Adjust sag by rotating the torsion spring
preload cams located on the rear torque arm. See illustration. The ideal
amount of sag for this rear suspension is five inches (12.7 cm) (X-Y=5
in./12.7 cm).

If the rear suspension rides in less than four inches or more than six
inches with the torsion spring preload cams at their maximum range of
adjustment, optional torsion springs (softer or stiffer, respectively) may
be required. This is only an initial setup, and final spring preload may
vary based on rider preference and riding conditions.

made by turning the adjustment screw located near the base of the
shock.

In half-turn increments, turn the screw clockwise to increase compres­sion valving and stiffen the ride. Turn the screw counterclockwise to
reduce compression and soften the ride. There are approximately three
full turns of adjustment available.

If bottoming continues after the screw has been turned fully clockwise,
the torsion spring should be adjusted (see page 44). Return the screw to
its original starting position after the torsion spring has been adjusted.

engine damage, do not operate the electric starter or pull-rope starter while
the engine is running.

56

OPERATION

Engine Break-In

No single action on your part is as important to long, trouble-free
machine life as proper break-in of a new or rebuilt engine. Premix the
first tank of gasoline with one pint of Polaris injection oil for each five
gallons of fuel. This, in addition to the lubrication supplied by the injec­tion system, will assure proper engine break-in.

CAUTION

Excessive heat build-up during the first three hours of operation will damage
close-fitted engine parts. Do not operate at full throttle or high speeds for
extended periods during the first three hours of use. Vary the throttle open­ings and machine speeds to reduce friction on all close-fitting machined
parts, allowing them to break in slowly without damage.

Use of any lubricants other than those recommended by Polaris may cause
serious engine damage. We recommend the use of Polaris lubricants for your
vehicle.

Drive with extra caution during the break-in period. Perform regular checks
on fluid levels, lines, and all other important areas of the machine.

57

OPERATION

Engine Break-In

Oil Injection System

Always fill the oil reservoir when refueling.

CAUTION

Serious engine damage can occur without the proper lubrication. Check the
oil tank level often during the first tank of fuel. If the oil level doesn't go down,
contact your dealer immediately.

Oil Recommendations

This snowmobile is equipped with a variable exhaust system (VES).
Engine lubrication comes from oil added to the fuel and oil injection
systems. Polaris recommends the use of VES II 2 Cycle Oil for this
engine. See page 112 for the part numbers of Polaris products.

Never mix brands of oil. Serious chemical reactions can cause injection
system blockage, resulting in serious engine damage. Oils may also be
incompatible and the result could be sludge formation, filter blockage,
and reduced cold weather flow rates. All Polaris oils are compatible
with each other.

Slide Rail and Track Cooling

CAUTION

Inadequate cooling and lubrication will lead to overheating of the slide rail
and track, resulting in premature wear and failure. Reduce speeds and fre­quently drive into fresh snow to allow adequate cooling and polishing of the
slide rail and track surfaces. Avoid operating on ice, hard-packed surfaces or
roads.

58

OPERATION

Track Warm-Up

WARNING

A loose track or flying debris could cause serious injury or death. Stand clear
of the front of the machine and the moving track. Never hold the snowmobile
up or stand behind it while warming up the track. Do not use excessive throt­tle during warm-up or when the track is free-hanging. Be sure the rear sup­port is stable.

WARNING

Use of traction products such as studs, ice growsers, etc. will increase the
possibility of track damage and/or failure. This could cause loss of control,
resulting in serious injury or death. Always inspect for track damage before
operating the snowmobile.

Follow these steps to ensure proper warm-up
of the engine, drive train and track.

1. Use an appropriate stand to securely
support the rear of the snowmobile at the
rear bumper. The track should be
approximately 4" (10 cm) off the
ground.

2. Start the engine and allow it to warm up

two to three minutes.

3. Depress the throttle abruptly and allow

the track to rotate several revolutions.

NOTE: It will take longer to warm up the track sufficiently during colder out-

Fuel Safety

WARNING

Gasoline is highly flammable and explosive under certain conditions.

• Always exercise extreme caution whenever handling gasoline.

• Always refuel outdoors or in a well-ventilated area.

• Always turn off the engine before refueling.

• Do not overfill the tank. Do not fill the tank neck.

• Do not smoke or allow open flames or sparks in or near the area where
refueling is performed or where gasoline is stored.

• If gasoline spills on your skin or clothing, immediately wash it off with soap
and water and change clothing.

• Never start the engine or let it run in an enclosed area. Engine exhaust
fumes are poisonous and can cause loss of consciousness or death in a
short time.

WARNING

The engine exhaust from this product contains chemicals known to cause
cancer, birth defects or other reproductive harm. Operate this vehicle only
outdoors or in well-ventilated areas.

60

OPERATION

Fuel

For peak performance, Polaris recommends the use of 91 octane or
higher fuel. Although 87 octane fuel is usable, some engine perfor­mance will be lost and fuel economy will decrease. Do not use lower
than 87 octane fuel. Do not use fuel containing more than 10% ethanol
(including E85).

CAUTION

Operating with obstructed fuel systems will result in serious engine damage.
Perform maintenance as recommended.

Damage to the fuel pump will occur if the snowmobile is operated with an
empty fuel tank. Do not allow the snowmobile to run out of fuel. Always refuel
when the level is low.

Prolonged exposure to petroleum based products may damage paint. Always
protect painted surfaces when handling fuel.

Fuel System Deicers

If you use non-oxygenated fuel, Polaris recommends the regular use of
isopropyl-based fuel system deicer. Add one to two ounces per gallon
(8-16 ml per liter) of gasoline to prevent engine damage resulting from
fuel system icing and lean fuel mixtures. Never use deicers or additives
containing methanol. Polaris also recommends the use of Carbon Clean
Plus. See page 112 for the part numbers of Polaris products.

If you use oxygenated fuel containing ethanol, additional alcohol deic­ers or water absorbing additives should not be used.

61

OPERATION

Oil

n Low Oil Indicator Light

The low oil indicator light will alert the operator if the oil level is low.
Visually check for oil in the bottle. Add oil before further operation of
the snowmobile. See page 58 for oil recommendations.

CAUTION

Operating the snowmobile without adequate engine lubrication can result in
serious engine damage. Always check the oil level when refueling. Add oil
as needed.

n Low Oil Level

Maintaining the proper oil level will prevent system aeration and possi­ble loss of pumping action, which could result in engine damage. This is
especially important when the machine is operated in mountainous ter­rain.

Maintain the oil level at the bottom of the filler neck. Always check and
fill the oil tank when refueling. Never operate the engine if oil is not vis­ible in the tank.

NOTE: The Polaris oil cap on the oil bottle is vented to allow proper oil flow.

See your Polaris dealer for recommended replacement parts.

WARNING

Objects towed with a rope have no braking power and can easily collide with
the rear of the snowmobile or other objects, resulting in serious injury or
death. DO NOT tow toboggans, sleds, saucers, or any type of vehicle with a
rope. Only a stiff metal pole connecting the towed object and the tow hitch on
the snowmobile should be used. If passengers are to be towed on a tobog­gan or sled, make sure the pole is at least four feet (1.2 meters) long to pre­vent any possibility of contact between the snowmobile's track and a person
riding in the towed object.

Braking distances increase when towing loads. Slow down to maintain con­trol of the snowmobile.

If the snowmobile becomes inoperable and must be towed, and if it isn't
possible to use a rigid tow bar, attach the tow rope to the ski spindles
(not to the ski loops) to prevent damage to the steering components.
Remove the drive belt before towing, and have someone ride on the
towed snowmobile to operate the brake and steering when necessary.

CAUTION

Towing a disabled snowmobile with the drive belt in place can result in seri­ous damage to the engine and drive system. Always remove the drive belt
from a disabled snowmobile before towing.

MAINTENANCE

Spark Plugs

Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine has been warmed up
and the vehicle has been driven at higher speeds. Immediately check the
spark plug for correct color.

WARNING

A hot exhaust system and engine can cause serious burns. Wear protective
gloves when removing a spark plug for inspection.

NOTE: On carbureted models, incorrect fuel mixture can often cause a spark

plug to appear too dark or too light in color. Before changing spark
plug heat ranges, be sure the correct main jet is installed in the carbu­retor(s). Refer to the Owner's Manual Supplement or see your dealer.

Normal Spark Plug

The normal insulator tip is gray, tan or light brown. There will be few
combustion deposits. The electrodes are not burned or eroded. This indi­cates the proper type and heat range for the engine and the service.

NOTE: The tip should not be white. A white insulator tip indicates overheating,

caused by use of an improper spark plug or incorrect carburetor/throt­tle body adjustments.

Wet Fouled Spark Plug

The wet fouled insulator tip is black. A damp oil film covers the firing
end. There may be a carbon layer over the entire nose. Generally, the
electrodes are not worn. General causes of fouling are excessive oil, use
of non-recommended injection oil, improper use of the choke, or incor­rect carburetion adjustments.

79

MAINTENANCE

Spark Plugs

A new engine can cause temporary spark plug fouling due to the preser­vative added during the assembly process. Avoid prolonged idle speeds,
which cause plug fouling and carbonization. Change the spark plugs
every 2000-2500 miles (3200-4000 km).

CAUTION

Using non-recommended spark plugs can result in serious engine damage. A
spark plug with a heat range too high will always cause engine damage if the
engine is operated in conditions more severe than intended for that plug.
Always use the spark plugs recommended for your snowmobile. See your
Owner’s Manual Supplement.

• Use recommended spark plugs with the proper gap.

• Use only resistor-type spark plugs.

• Torque spark plugs to 18-22 ft. lbs. (24-30 Nm).

• Always carry spare spark plugs.

Spark Plug Removal and Replacement

1. Remove the spark plug cap.

2. Using the special wrench provided in the tool pouch, rotate the
spark plug counterclockwise to remove it.

3. Reverse the procedure for spark plug installation.

4. Torque to specification.

5. Reinstall the spark plug cap.

80

MAINTENANCE

Intake Filters

The intake foam filter limits
snow ingestion into the intake
system. When operating in loose
powder snow, check the top of
the foam filter periodically to
remove any accumulation of

snow.

CAUTION

Operating the 600 RMK with the intake filters removed may cause carburetor
icing. The result will be poor fuel economy or carburetor malfunction. Always
reinstall the intake filters before operating the snowmobile.

dealer. Do not attempt to service the fuel pump.

Fuel Filter

See your Polaris dealer for replacement of the fuel filter at the intervals
outlined in the Periodic Maintenance Table beginning on page 72.

Fuel Lines

Inspect the fuel lines regularly for signs of deterioration or damage.
Always check fuel line condition after periods of storage. Normal dete­rioration from weather and fuel compounds may occur. Replace worn or
damaged fuel lines promptly.

CAUTION

Kinking the fuel lines or using a pliers or similar tools to remove fuel lines
may cause damage to the lines. If a fuel line has been damaged or kinked,
replace it promptly.

Oil Lines

Inspect oil line condition at the intervals outlined in the Periodic Main­tenance Table beginning on page 72.

Oil Filter

Have your dealer change the oil filter
and bleed the system at the intervals
outlined in the Periodic Maintenance
Table beginning on page 72.

NOTE: The direction of the arrows indi-

82

cates the direction of flow
through the filter.

MAINTENANCE

Carburetor (600 RMK)

The number stamped in the end of the main jet indicates the jet size. The
jet installed at the time of manufacture is not necessarily correct for your
elevation. It's your dealer's responsibility to make sure the correct main
jet is installed.

CAUTION

Operating the snowmobile with incorrect jetting can result in serious engine
damage. Have your Polaris dealer perform all carburetor adjustments to
ensure all adjustments are done correctly.

Carburetor Adjustments (600 RMK)

The frequency at which the carburetors are synchronized or balanced is
important. Properly adjusted carburetors can greatly improve engine
performance, fuel economy, engine life, and reliability.

If you notice any of the following conditions, the carburetor may need
adjustment:

• Hard starting

• Poor idle

• Overheated pistons and cylinder walls

• Plug fouling

• Poor engine response to various throttle valve openings

Carburetor Water/Sediment Trap (600 RMK)

Most Polaris snowmobiles contain patented carburetor bowl water/sedi­ment traps located at the bottom of each carburetor. The trap, consisting
of a hose with a plug, should be drained about every 1000 miles (1600
km) and inspected for contamination.

WARNING

When draining the traps, fuel spillage will occur. Always work in a well venti­lated area away from anything that may cause the fuel to ignite, such as open
flames, sparks, heaters, trouble lights, cigarettes, etc. Review the fuel warn­ings on page 60.

Cleaning Procedure

1. Turn the fuel valve off.

2. Place a container or shop
towels below the plug to
catch drained fuel.

3. Slide the clamp away from
the drain plug and remove
the drain plug from the sedi­ment tube.

4. Wipe residue from the plug
and reinstall it. Reposition
and tighten the clamp.

5. Repeat the draining proce­dure for any remaining traps.

Exhaust System

Check the exhaust system for wear or damage at the intervals outlined in
the Periodic Maintenance Table beginning on page 71.

WARNING

Hot exhaust system parts can cause serious burns. Allow adequate time for
the exhaust system to cool. Never perform this procedure with the engine
running.

Always allow the engine and exhaust system to cool completely before
inspecting.

1. Open the hood and inspect the muffler and pipes for cracks or dam­age.

2. Check for weak or missing retaining springs or damper/support

grommets.

3. Check for loose clamps on the pipe covers.

MAINTENANCE

Cooling System

Coolant

The coolant supplied in the system is a 60/40 mixture of ethylene-glycol
and distilled water. This mixture provides protection against freezing.
Contact your dealer if greater protection is required.

Use Premium 60/40 anti-freeze coolant, which is already premixed and
ready to use. Do not dilute with water. Never exceed a 60% antifreeze/
40% water mixture. See page 112 for the part numbers of Polaris prod­ucts.

NOTE: Never add tap water to the cooling system. Minerals cause deposits

n Coolant Level

The engine coolant level is controlled by the recovery system. The
recovery system components are:

• Coolant bottle or overflow tank

• Filler neck

• Pressure cap

• Connecting hoses
Always maintain the coolant level between the minimum and maximum

marks on the coolant bottle (when engine is cold) to prevent overheating
and serious engine damage.

and may react adversely with the metals in the engine and cooling
system.

CAUTION

Operating the snowmobile with insufficient coolant will result in overheating
and serious engine damage. Always maintain the coolant level as recom­mended.

Coolant High Temperature Indicator Light

The high temperature indicator light will illuminate when engine cool­ant temperature becomes too hot for safe continued operation of the
engine. If you must drive your snowmobile after the high temperature
indicator light has come on, drive slowly and stop frequently to allow
the engine to cool down. Driving in deep snow will also help cool the
engine. See your dealer for service. Add coolant if the level is low.

NOTE: Engine performance will be reduced if you continue operating when

Flushing the Cooling System

To ensure that the coolant maintains its ability to protect the engine,
drain the system completely every two years and add a fresh mixture of
antifreeze and distilled water. This service must be performed when the
engine is cold. Ask your Polaris dealer to check the coolant when he
performs the fall tune-up on your snowmobile.

Bleeding the Cooling System

WARNING

Steam and hot liquids will cause serious burns to your skin. Never bleed the
cooling system or remove the pressure cap when the engine is warm or hot.

Use of a non-standard pressure cap will not allow the recovery system to
function properly. If the pressure cap needs replacement, contact your
dealer for the correct part.

CAUTION

If coolant flow becomes restricted or plugged, coolant loss, air lock or engine
damage may result. Most cooling systems are equipped with a filter that
should be periodically inspected or replaced.

Bleeding the Cooling System

Bleed the cooling system at the intervals outlined in the Periodic Main­tenance Table beginning on page 72. Perform the bleeding procedure
when the engine is cold.

1. Remove the pressure cap and fill the coolant bottle with properly
mixed coolant to the maximum mark.

2. Elevate the front end of the machine slightly to aid in bleeding of

the heat exchangers.

3. Remove the bleed screw from the water outlet manifold and/or the

thermostat housing. Allow the coolant to bleed through the system
until it runs out the bleed holes. Reinstall the bleed screw into the
manifold.

4. Add coolant to the coolant bottle to the maximum mark.

5. Start the engine and run at a fast idle for two to three minutes.

Loosen the bleed screw occasionally to purge any trapped air.

6. Stop the engine and check the coolant bottle level. Fill as required.

7. Feel the heat exchangers under the running boards. If the system is

bled properly, they'll be warm to the touch. If they're not, repeat step

5. Lift the front of the machine slightly to assist in the bleeding.

Brakes

n Hydraulic Brake Inspection

Inspect the brake lever travel before each use of the snowmobile. See
page 51.

Brake pads must be replaced when the brake pad material becomes thin­ner than the backing plate, approximately 1/16" (1.5mm). A kit is avail­able for replacing brake pads. See your dealer.

WARNING

Brake failure during operation can result in serious injury or death. Properly
functioning brakes are vital to your safety. Be sure the brake pads do not
drag on the disc and that brake lever travel is not excessive.

Always replace brake pads when the brake pad material becomes thinner
than the backing plate, approximately 1/16" (1.5mm).

n Brake Fluid

WARNING

After opening a bottle of brake fluid, always discard any unused portion.
Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it rap­idly absorbs moisture from the air. The moisture causes the boiling tempera­ture of the brake fluid to drop, which can lead to early brake fade and the
possibility of accident or serious injury.

WARNING

Keep the master cylinder cover free of dirt and debris. The vent slits allow for
diaphragm movement, and if they become plugged, movement of brake fluid
below the diaphragm may be restricted, altering brake function.

CAUTION

Brake fluid will damage decals, paint and some plastics. Always wipe up
spills immediately.

Replace brake fluid at least every two
years with Polaris DOT 4 high tem­perature brake fluid. See page 112 for
the part numbers of Polaris products.

The brake fluid level can be seen
through a plastic sight glass in the
brake reservoir. If the fluid is suffi­cient, the sight glass will be black. If
the sight glass is any color other than
black, add brake fluid.

Brakes

Bleeding the Hydraulic Brake System

Air in the hydraulic brake system will cause spongy brake lever action.
Bleed the system before operating the snowmobile.

WARNING

Operating the vehicle with a spongy brake lever can result in loss of brakes,
which could cause an accident and lead to serious injury or death. Never
operate the vehicle with a spongy-feeling brake lever.

During the bleeding procedure, keep the brake handle as level as possi­ble. The reservoir must be in this position to minimize the possibility of
air entering the system through the reservoir vent.

1. Remove brake master cylinder reservoir cover and gasket.

2. Fill the master cylinder reservoir to between the MIN and MAX

marks or 1/4"-5/16" (.6-.8 cm) below the lip of the reservoir open­ing. Reinstall the gasket and cover.

3. Slip a rubber tube over the ball of the bleeder valve and direct the

flow of fluid into an approved container.

4. Squeeze the brake lever a full stroke. Then unscrew the bleeder

valve 3/4 of a turn to release air.

5. Close the bleeder valve and release the brake lever.

6. Repeat steps 4 and 5 until fluid flows from the bleeder valve in a

solid stream free of air bubbles.

WARNING

Overfilling the master cylinder leaves no room for fluid expansion and may
cause the brakes to lock, resulting in serious injury or death. Always add
brake fluid to the fill line as recommended.

7. After bleeding is complete, refill the reservoir to the proper level.

See page 93.

8. Reinstall the gasket and cover.

MAINTENANCE

Clutch System

Periodically inspect clutch sheaves for damage, wear or belt residue. To
maintain optimum performance, clean with non-oil based cleaners such
as isopropyl alcohol.

WARNING

If you become aware of higher than normal clutch engagement or an unusual
vibration or shift pattern, see your dealer immediately. Do not operate the
snowmobile until repairs have been made.

All clutch maintenance and repairs must be performed by an authorized
Polaris dealer. Any unauthorized modifications to clutches, such as adding or
removing weights, will void the warranty.

CAUTION

The bushings in the weights and rollers of Polaris clutches are made of a
material that may be damaged if lubricated. Do not lubricate clutch bushings.

Clutch Alignment and Offset

Clutch alignment offset is important for
maintaining optimum performance. See your
Owner's Manual Supplement for the recom­mended offset between the drive and driven
clutches with the belt removed.

Belt width and length must match the center
distance of the clutches and sheave width of
the drive clutch. Polaris recommends the use
of O.E.M. belts. Other belts may match the
dimensions, but can drastically change the
shift pattern, resulting in poor performance.
See your dealer for service and adjustments.

NOTE: A worn belt will continue to function, but

will not deliver maximum performance.
Always carry a spare belt in case of an
emergency.

always carry a spare. Inspect the belt for signs of excessive wear: frayed
edges, missing cogs, cracks and excessive looseness. Replace the belt if
any of these conditions exist. See Drive Belt Troubleshooting on page

117.

For improved drive-away during extremely cold temperatures, remove
the belt and warm it to room temperature. Reinstall it before starting the
snowmobile.

n Drive Belt Deflection

Measure belt deflection with both
clutches at rest and in their full
