  • Page 130: Storage Tips

    123. Stabilize the Fuel 1. Fill the fuel tank. 2. Add Polaris Carbon Clean Fuel Treatment or Polaris Fuel Stabilizer. Follow the instructions on the container for the recommended amount.

  • Page 131: Fluid Levels

    5. Turn the engine over several times. Oil will be forced in and around the piston rings and ring lands, coating the cylinder with a protec- tive film of fresh oil. 6. If Polaris fuel system additive is not used, the fuel tank, fuel lines, and injectors should be completely drained of gasoline.
  • Page 132 Set the tire pressure and safely support the ATV with the tires slightly off the ground. Be sure the storage area is well ventilated. Cover the vehicle with a genuine Polaris cover.
