OPERATION

Track Warm-Up

WARNING! 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. Use a 
stable rear support.

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 snow-

mobile 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 sufficiently during colder outdoor 

temperatures.

4. Release the throttle, apply the brakes, shut off the engine and lower 

the snowmobile 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

Fuel

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 refu-

eling 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.

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

OPERATION

Fuel Recommendation

For peak performance, POLARIS recommends the use of 91 octane fuel 
or higher, with no ethanol. 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. Never use E85 fuel in your snowmobile.

NOTICE: Operating with obstructed fuel systems will result in serious engine 

damage. Perform maintenance as recommended.

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

Fuel System Deicers

If you use non-ethanol fuel (sometimes labeled “non-oxygenated”), 
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 damage resulting from fuel system icing. Never use deicers 
or additives containing methanol. POLARIS recommends the use of 
Carbon Clean Plus. See page 116 for the part numbers of POLARIS 
products.

If you use fuel with up to 10% ethanol (sometimes labeled “oxygen-
ated”) do not add deicers or additives that contain any form of alcohol.

OPERATION

Oil

Low Oil Level

Always maintain the oil level between 
the “add” mark and the bottle neck. 
Do not fill the bottle neck. See page 
64 for oil recommendations.

1. Immediately stop the engine if the 

low oil indicator light comes on.

2. Open

 

the left side panel.

3. View the oil level in the oil bottle.

4. Add oil as needed before operating. 

NOTICE: Operating the snowmobile without adequate engine lubrication can 

result in serious engine damage. Always check the oil level when refu-
eling. Add oil as needed.

The oil bottle cap is vented to allow proper oil flow. See your POLARIS 
dealer for recommended replacement parts.
