AIR FILTER / AIR BOX
Replace the air filter. See page 117. Clean the air box.
FLUID LEVELS
Inspect the fluid levels. Add or change fluids as recommended in the Periodic
Maintenance Chart section.
• Demand drive fluid (front gearcase)
• Rear gearcase fluid (if equipped)
• Transmission fluid
• Brake fluid (change every two years and any time the fluid looks dark or
contaminated)
• Coolant (test strength/fill)
INSPECT AND LUBRICATE
Inspect all cables and lubricate all areas of the vehicle as recommended in the
Periodic Maintenance Chart section.
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" 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
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.
