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. 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” (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 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

Inadequate cooling and lubrication will lead to overheating of the slide 
rail and track, resulting in premature wear and failure. 

1. Reduce speeds and frequently drive into fresh snow to allow ade-

quate cooling and polishing of the slide rail and track surfaces. 

2. 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.

• Turn the fuel valve off whenever the snowmobile is stored or parked.

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.

OPERATION

Fuel

Your POLARIS engine is designed to run on 87 octane non-oxygenated 
or 89 octane oxygenated pump gasoline. There's a great deal of variabil-
ity in the quality of the 87 octane gasoline available across the country, 
so we encourage the use of premium fuel when possible. Do not use fuel 
containing more than 10% ethanol (including E85)
.

NOTICE: Using fuels with a lower than recommended octane or operating with 

obstructed fuel systems will result in serious and costly engine dam-
age. Always use the recommended fuels for your machine.

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 102 for the part numbers of POLARIS products.

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

Fuel Valve

The fuel valve is located between the 
oil bottle and engine intake duct. 
Turn the fuel valve off whenever the 
snowmobile is stored or parked.

Turn the fuel valve clockwise to OFF 
to shut off the fuel supply.

Turn the valve counter-clockwise to 
ON to turn the fuel supply on.

OPERATION

Oil

Low Oil Indicator Light

The low oil indicator light may flicker at times due to oil movement in 
the bottle, but when the light comes on and remains on, add the recom-
mended oil before further operation. See page 49 for oil recommenda-
tions.

Visually check for oil in the bottle. The engine may be operated as long 
as oil is visible in the oil tank. If oil is not visible, continued operation 
may cause serious engine damage.

Low Oil Level

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

NOTICE: Operating the snowmobile without adequate engine lubrication can 

result in serious engine damage. Always check the oil level when 
refueling. Add oil as needed.

Always maintain a visible level of oil in the tank. If oil is not visible, 
continued operation may cause serious engine damage. See page 49 for 
oil recommendations.

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