Ensure the fuel valve is open, the key is in the ignition, and the engine stop switch is in the run position. Pull the starter handle briskly to start the engine.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol-blended fuels higher than E10.
Change the engine oil every 50 hours of operation or at the start of each season, whichever comes first.
Check the fuel level, ensure the fuel valve is open, inspect the spark plug, and verify that the engine stop switch is in the run position.
Elevate the rear of the snowmobile, loosen the axle bolts, adjust the tension bolts evenly until the track deflection is within specifications, and then retighten the axle bolts.
Stabilize the fuel, change the oil, lubricate all fittings, clean the snowmobile, and store it in a dry, covered location.
Ensure proper track tension, ski alignment, and adjust the suspension settings according to rider preference and terrain conditions.
Stop the engine, allow it to cool, check for coolant leaks, ensure the cooling fins are not obstructed, and verify the proper oil level.
Remove the spark plug cap, use a spark plug socket to remove the old spark plug, check the gap on the new plug, and install it, ensuring it is snug but not overtightened.
The Polaris 120 XC does not have tires as it is a snowmobile; ensure the skis and track are in good condition for optimal performance.
