ADULT SECTION

Maintenance

Storage

Stabilize the Fuel

Proper off-season preparation of the engine and fuel system is vital to 

the prevention of rust and corrosion formation on precision engine parts 

during storage. See page 82 for the part numbers of Polaris products.
1. Fill the fuel tank with fresh fuel.
2. Add Polaris Carbon Clean Fuel Treatment or Polaris Fuel Stabilizer. 

Follow the instructions on the container for the recommended 

amount.

NOTE:

Carbon Clean removes water from fuel systems, stabilizes fuel and 

removes carbon deposits from pistons, rings, valves and exhaust sys-

tems.

3. Start the engine. Allow it to idle for five minutes to disperse addi-

tives through the entire fuel system.

4. Turn the fuel valve off.

Maintenance

Storage

Track and Suspension

Support the rear of the snowmobile 

slightly off the ground with an appropriate 

snowmobile support. This will allow the 

track to hang freely.
Elevate the front end of the machine and 

place blocks securely under it to remove 

tension from the shocks and springs. This 

will minimize fatigue on the front shocks 

and springs.
Storage Area

Your snowmobile should be stored in a dry garage or shed, out of direct 

sunlight. It should be covered with a fabric snowmobile cover. Plastic 

covers can cause condensation to form and may damage some snowmo-

bile components.

Maintenance

Transporting the Snowmobile

Whenever the snowmobile is transported the following measures should 

be taken:
1. Turn the fuel valve off.
2. Be sure the fuel cap is installed correctly.
3. Always tie the snowmobile to the transporting unit securely using 

suitable straps.

Fall Tune-Up

To obtain maximum performance from your snowmobile, we encourage 

you to arrange for a fall service tune-up with your Polaris dealer. 
Towing

Do not pull or tow any person or object behind this snowmobile. If a 

disabled snowmobile must be towed by another snowmobile, attach the 

tow rope to the spindles of the disabled snowmobile, not to the ski toe 

loops.
Emergency Preparation

For your added protection, carry the following items in your snowmo-

bile when traveling farther than a five-minute walk from home.
• Extra Spark Plugs
• First  Aid  Kit
• Winter Survival Kit
• Extra  Gloves
• Owner's Manual
