Ensure the ATV is in neutral, turn the ignition key to the "ON" position, and press the electric start button. If equipped, make sure the choke is used appropriately in cold conditions.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol blends higher than E10.
Change the oil every 20 hours of operation or at least once a year, whichever comes first. Always use the recommended oil type as specified in the owner's manual.
Overheating can be caused by low coolant levels, a clogged radiator, or a malfunctioning fan. Ensure coolant levels are adequate and inspect the radiator for debris.
Loosen the rear axle nuts, adjust the chain tensioner until the chain has about 1/2 inch of slack, then retighten the axle nuts securely.
Check the battery connections for corrosion, ensure the battery is not dead, and inspect the charging system components such as the stator and rectifier for faults.
Remove the spark plug wire, unscrew the spark plug using a spark plug wrench, replace it with a new plug of the same specifications, and reattach the spark plug wire securely.
Check if the ATV is in neutral, ensure the battery is charged, verify the kill switch is not engaged, and inspect the fuel supply. If the problem persists, consult a professional technician.
Regularly check the brake fluid level, inspect brake pads for wear, and ensure all brake components are clean and functioning correctly. Replace any worn parts as needed.
The recommended tire pressure is usually around 4 psi in the front tires and 4 psi in the rear tires. Always refer to the owner's manual for the exact specifications.
