OPERATION

Engine Break-In

Oil Injection System

Always check and fill the oil tank when refueling. See page 59.

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 the use of VES II 2 Cycle Oil for this 

engine. See page 113 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.

CAUTION

Serious engine damage can occur without the proper lubrication. Check the 

oil tank level often during the first tank of fuel. If the oil level doesn't go down, 

contact your dealer immediately.

OPERATION

Track Warm-Up

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 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 revo-

lutions.

NOTE: 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.

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 throt-

tle during warm-up or when the track is free-hanging. Use a stable rear sup-

port.

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.

56

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.

OPERATION

Fuel

Fuel Valve

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.

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.
