MAINTENANCE
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 plugs and add 2-3 tablespoons of engine oil. To access
the plug holes, use a section of clear 1/4 in (6.35 mm) 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 plugs. Torque to specification. See the Spark Plug Gap /
Torque section for details.
4. Apply dielectric grease to the inside of each spark plug cap. Do not reinstall
the caps onto the plugs 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. If POLARIS fuel system additive is not used, fuel tank, fuel lines, and
injectors should be completely drained of gasoline.
7. Reinstall the spark plug caps to the spark plugs.
BATTERY MAINTENANCE
See the Battery section for storage and charging procedures.
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.
REMOVAL FROM STORAGE
Engine exhaust contains poisonous carbon monoxide and can cause loss of
consciousness or death. Never run an engine in an enclosed area.
1. Charge the battery if necessary.
2. Make sure the spark plug is tight. Reinstall the fuse box cover if it was
removed for storage.
3. Fill the fuel tank with fuel.
