OPERATION

Engine Break-In

Oil Injection System

Always check and fill the oil bottle when refueling. See page 65.

NOTICE: Serious engine damage can occur without the proper lubrication. 

Check the oil bottle 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 using Polaris Semi-Synthetic Oil for premixing the 

first tank of fuel at 40:1 (one pint of oil per 5 gallons of fuel) and for the 

first fill of the oil tank. After this initial treatment, Polaris recommends 

the use of VES Gold Plus Synthetic 2-cycle oil. See page 110 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.

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 4I (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.

Fuel Recommendation

For peak performance, Polaris recommends the use of 91 octane fuel or 

higher. 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.

OPERATION

Fuel Resistor

This snowmobile is equipped with a 

feature that allows the engine control-

ler to select the proper operating soft-

ware based on the type of fuel being 

used. The proper fuel resistor must be 

installed to match the type of fuel you 

are using.
The snowmobile comes from the fac-

tory with the resistor installed that 

should be used when operating with 

fuel containing up to 10% ethanol. 

The resistor is labeled “10% ETHA-

NOL 24 OHM” (see illustration). 
The resistor is installed into the wir-

ing harness on the left side of the 

snowmobile just above the top of the 

oil bottle (see photo).
If the snowmobile is operated with 

non-ethanol fuel be sure to install the 

resistor labeled “NON-ETHANOL 

160 OHM”. This resistor is provided 

in the tool kit. 

NOTICE: Engine damage may occur if ethanol fuel is used while the non-etha-

nol fuel resistor is installed. The check engine light may also display in 

this condition as this could cause detonation. 

If you’re unsure of the type of fuel in the fuel tank, make sure the 

“10% ETHANOL 24 OHM” resistor is installed. This is the preferred 

default and will provide the most engine protection.

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 Car-

bon Clean Plus. See page 110 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.
