It is recommended to inspect the drive belt every 50 hours of use and replace it as necessary, or at least once a season.
To winterize, stabilize the fuel, change the oil, lubricate all fittings, remove the battery, and store in a dry place. Cover the snowmobile to protect it from dust and moisture.
Check the fuel level, ensure the choke is properly set, inspect the spark plug for fouling, and verify the battery condition. Ensure the kill switch is in the 'run' position.

To check and refill the coolant, locate the coolant reservoir, ensure the engine is cool, check the level, and fill with Polaris Antifreeze/Coolant if needed.
If overheating occurs, stop the engine immediately, check coolant levels, inspect for leaks, and ensure the cooling fan is operational. Allow the engine to cool before proceeding.
To adjust the brakes, locate the brake adjuster near the handlebars, turn the adjuster to increase or decrease tension as needed, and ensure the brakes engage smoothly without excessive force.
