Storage Tips

Inspect and Lubricate
Inspect all cables and lubricate all areas of the vehicle as 

recommended in the Periodic Maintenance Chart beginning on page 

57.
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 hole, use a section of clear 1/4” hose and a small

plastic squeeze bottle filled with the pre-measured amount of oil.

3. Reinstall the spark plug. Torque to specification. See page 71.
4. Apply dielectric grease to the inside of the 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. If fuel system additive is not used, fuel tank, fuel lines, and

injectors should be completely drained of gasoline.

7. Reinstall the spark plug cap to the spark plug.

Cleaning and Storage

Removal from Storage

1. Check the battery and charge if necessary. Install it in the vehicle. 
2. Make sure the spark plug is tight.
3. Fill the fuel tank with fuel.
4. Check all the points listed in the Daily Pre-Ride Inspection section 

on page 43. Tightness of the bolts, nuts and other fasteners should 

be checked by an authorized POLARIS dealer or other qualified 

service facility.

5. Lubricate at the intervals outlined in the Periodic Maintenance 

Chart beginning on page 57.

Battery Maintenance 
See pages 90-92 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.
