FLUID LEVELS
Inspect the fluid levels. Add or change fluids as recommended in the Periodic
Maintenance Chart.
• Rear gearcase fluid
• Transmission fluid
• Brake fluid (change every two years and any time the fluid looks dark or
contaminated)
INSPECT AND LUBRICATE
Inspect all cables and lubricate all areas of the vehicle as recommended in the
Periodic Maintenance Chart.
FOG THE ENGINE
1. Treat the fuel system with POLARIS Carbon Clean or other equivalent fuel
treatment. Follow the instructions on the container. Start the engine. Allow it
to idle for several minutes so the Carbon Clean reaches the injectors. Stop
the engine.
2. Remove the spark plug 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 pre-measured amount of oil.
Do this carefully! If you miss
the plug holes, oil will drain from the spark plug cavities into the hole at the
front of the cylinder head, and appear to be an oil leak.
3. Reinstall the spark plug. Torque to specification.
4. Apply dielectric grease to the inside of each spark plug cap. Do not reinstall
the cap onto the plug at this step .
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 protective film of fresh
oil.
6. Reinstall the spark plug caps.
7. If POLARIS fuel system additive is not used, fuel tank, fuel lines, and
injectors should be completely drained of gasoline.
STORAGE AREA / COVERS
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.
