It is recommended to change the oil every 50 hours of use or every 6 months, whichever comes first. Always use the recommended oil type specified in the owner’s manual.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol blends higher than E10 to prevent engine issues.
Check the battery for charge and connections, ensure the fuel is fresh, inspect the spark plug for wear or fouling, and make sure the fuel valve is open.
The front tires should be inflated to 5.0 psi and the rear tires to 5.0 psi. Always check the tire pressure when the tires are cold.
Remove the air filter cover, take out the air filter, and clean it with a mild detergent and water. Let it dry completely before reinstalling.
Turn off the engine and let it cool down. Check the coolant level and look for any leaks. Ensure that the radiator is clear of debris.
Routinely inspect brake pads for wear and replace if necessary. Check the brake fluid level and top up with the recommended DOT 4 brake fluid as needed.
Locate the idle adjustment screw on the carburetor. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it, aiming for a smooth idle.
Common causes include a clogged air filter, dirty fuel filter, worn spark plug, or incorrect valve clearance. Regular maintenance can prevent these issues.
Clean the ATV thoroughly, change the oil, top off all fluids, disconnect the battery, and store it in a dry and covered location. Consider using a fuel stabilizer.
