ADULT SECTION

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
