OPERATION

Track Warm-Up

A loose track or flying debris could cause serious injury or death. Stand clear of 
the front of the snowmobile 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.

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 
about 4 inches (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.

TIP: It will take longer to warm up the track suffi-

ciently during colder outdoor temperatures.

4. Release the throttle, apply the brakes, 

shut off the engine and lower the machine to the ground.

5. Grasp the skis by their front loops and move them from side to side 

to loosen snow and ice.

Slide Rail and Track Cooling

NOTICE: 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.

OPERATION

Carburetion

Proper carburetor adjustment is critical. A lean mixture (too much air, 
too little fuel) may result in piston burning, bearing failure, or complete 
engine failure. A rich mixture (too much fuel, too little air) may foul 
plugs and cause generally poor engine performance.

A lean mixture may be caused by things like fuel line restrictions, 
foreign matter in the carburetor or clogged fuel filters. A rich mixture 
may be caused by snow build-up on the pre-filter in the air intake 
system. Either condition may be caused by improper carburetor 
adjustment.

CAUTION! Improper carburetor adjustments may result in operator safety 
hazards as well as serious engine damage. Always have your POLARIS dealer 
perform any carburetor adjustments.

Jetting Guidelines

Changes in altitude and temperature affect air density, which is the 
amount of oxygen available for combustion. In low elevations and cold 
temperatures, the air has more oxygen. In higher elevations and higher 
temperatures, the air is less dense.

The carburetors are calibrated for an altitude of 0-2000 ft. (0-600 m) and 
ambient temperatures from +15° to +35° F. (-9° to +2° C.). Carburetors 
must be re-calibrated if the snowmobile is operated outside this 
production temperature and/or altitude range. The main jet installed in 
production is not correct for all altitudes and/or temperatures. See page 
69 for more information.

NOTICE: A main jet that's too small will cause a lean operating condition and 

may cause serious engine damage. Jet the carburetors carefully for 
elevation and temperature according to the jetting charts for your 
vehicle. See page 99.

TIP: Always ensure that the correct jets are installed in the machine for the 

geographical area of operation. Be very careful when jetting down in warm 
weather. As the weather turns colder it will be necessary to re-jet upward to 
prevent engine damage. When selecting the proper main jet always use the 
lowest elevation and temperature that is likely to be encountered.

OPERATION

Daily Storage

At the end of each ride, park the 
snowmobile on a level surface and support 
it at the rear with an appropriate track 
stand. The track should be suspended 
approximately 4 inches (10 cm) off the 
ground.

Cover the machine with an appropriate 
cover.

Towing

For your safety, do not attempt to use a tow hitch until you've read the 
following warnings and understand the proper hitch functions.

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.

NOTICE: 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

Emission Control Information

Any qualified repair shop or qualified person may maintain, replace, or 
repair the emission control devices or systems on your snowmobile.

Emission Control Label

Your snowmobile is equipped at the time of sale with an emission 
control information (ECI) label and a factory-installed emissions 
information hangtag. These items are required by U.S. Environmental 
Protection Agency regulations. The ECI label is permanently affixed to 
either the right side of the tunnel or the engine recoil cover. The ECI 
label should not be removed, even after you purchase the snowmobile. 
You may remove the factory-installed emissions information hangtag, 
which is intended solely for your use in making a purchasing decision.

Emission Control Maintenance Requirements

Your snowmobile is certified to operate on gasoline with a minimum 
octane level of 91(R+M)/2. If your snowmobile is equipped with a 
check engine light and it comes on, you must take your snowmobile to a 
qualified dealer for diagnostic service. Specifications and adjustments 
for engine tune-ups are located in the Service Manual, which is 
available to your qualified service technician. Reverse (if equipped) 
must not be engaged during engine tune-ups.

Owner's Responsibilities

Please read the Snowmobile Engine Emissions Limited Warranty, and 
read the maintenance section of your owner's manual. You are 
responsible for ensuring that the specified maintenance is performed. 
POLARIS recommends that you contact an authorized POLARIS dealer 
to perform any service that may be necessary.

Non-ionizing Radiation

This vehicle emits some electromagnetic energy. People with active or 
non-active implantable medical devices (such as heart monitoring or 
controlling devices) should review the limitations of their device and the 
applicable electromagnetic standards and directives that apply to this 
vehicle.
