Fluid Levels
Inspect the following fluid levels and change if necessary: engine oil;
transmission oil; brake fluid (change every two years or as needed if
fluid looks dark or contaminated).
Engine
1. Remove the spark plug and pour 2-3 tablespoons of Premium 4
Synthetic 0W40 engine oil into the hole. Use a section of clear 1/4”
hose and a small plastic squeeze bottle filled with the pre-measured
amount of oil.
NOTE: Do this carefully! If you miss the plug hole, oil will drain from
the spark plug cavity into the hole at the front of the cylinder
head and appear to be an oil leak.
2. Reinstall the spark plug.
3. With the ignition off, turn the engine over several times using the
recoil starter. This will ensure coverage of the piston rings,
cylinder walls and crankshaft bearings.
4. Apply dielectric grease to the inside of the spark plug cap and install
the cap onto the plug.
5. Treat the fuel system with Polaris Carbon Clean.
6. If Polaris fuel system additive is not used, drain all fuel from the
fuel tank, fuel lines, and carburetor. Eliminate any fuel remaining
in the carburetor by running the engine until it stops.
Lubricate
Inspect all cables and lubricate with Polaris Cable Lubricant. Follow
lubrication guidelines in the maintenance section of the service or
owner’s manual to completely grease and lubricate the entire vehicle
with Polaris Premium All Season Grease. Apply Polaris O-Ring Chain
Lube to the drive chain.
Storage Area/Covers
Set the tire pressure and safely support the ATV with the tires 1-2” off
the ground. Be sure the storage area is well ventilated, and cover the
machine with a genuine Polaris ATV cover.
NOTE: Do not use plastic or coated materials. They do not allow
enough ventilation to prevent condensation, and may promote
corrosion and oxidation.
