MAINTENANCE Cleaning and Storage Storage Tips Fog the Engine 1. After stabilizing the fuel, remove the spark plugs and add 2-3 tablespoons of engine oil. To access the plug holes, use a section of clear 1/4" hose and a small plastic squeeze bottle filled with the premeasured amount of oil. 2. Reinstall the spark plugs. Torque to specification. 3. Apply dielectric grease to the inside of each spark plug cap and reinstall the caps onto the plugs. 4. Turn the engine over several times using electric start. Oil will be forced in and around the piston rings and ring lands, coating the cylinder with a protective film of fresh oil. 5. If POLARIS fuel system additive is not used, the fuel tank, fuel lines, and injectors should be completely drained of gasoline. Air Filter / Air Box 1. Inspect and clean (or replace) the pre-cleaner and air filter. See page 99. 2. Clean the air box. Inspect and Lubricate Inspect all cables and lubricate all areas of the vehicle as recommended in the Periodic Maintenance Chart beginning on page 79. Battery Maintenance Remove the battery and recharge it as outlined on page 118. Store the battery in a cool, dry place. Storage Area/Covers 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. Do not use plastic or coated materials. They do not allow enough ventilation to prevent condensation, and may promote corrosion and oxidation. 123
