OPERATION

Slide Rail and Track Cooling

Fuel

CAUTION

Inadequate cooling and lubrication will lead to overheating of the slide rail 

and track, resulting in premature wear and failure. Reduce speeds and fre-

quently 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.

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.

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

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.

to ON to turn the fuel supply on.

Fuel Recommendations

Your Polaris engine is designed to run on 87 octane non-oxygenated or 

89 octane oxygenated pump gasoline. There's a great deal of variability 

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). 

CAUTION

Using fuels with a lower than recommended octane or operating with 

obstructed fuel systems will result in serious and costly engine damage. 

Always use the recommended fuels for your machine.

OPERATION

Fuel

Fuel Reserve Capacity (Mechanical Gauge)

There are approximately two gallons of fuel left in the tank when the 

mechanical fuel gauge reads RES.

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 113 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.

CAUTION

Prolonged exposure to petroleum based products may damage paint. Always 

protect painted surfaces when handling fuel.

OPERATION

Oil

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.

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.

Always check the oil level when refueling. Maintain the oil level above 

the tank's low level line. When the oil reaches the low level mark, add 

one U.S. quart of recommended oil. See page 54 for oil recommenda-

tions.

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

flow. See your Polaris dealer for recommended replacement 

parts.

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.
