Regular maintenance includes checking and changing the oil, inspecting the air filter, adjusting the brakes, checking tire pressure, and lubricating moving parts. Always refer to the owner's manual for detailed instructions.
The recommended tire pressure is typically around 4 psi for both front and rear tires, but it's best to consult the owner's manual for exact specifications.
First, check the battery charge and connections. Ensure the fuel valve is open and there's enough fuel. Inspect the spark plug for wear or damage. If issues persist, consult a professional mechanic.
Use a high-quality 4-stroke engine oil with a viscosity grade suitable for the climate in which you operate the ATV. Refer to the owner's manual for specific recommendations.
It's recommended to change the oil every 20 hours of operation or at least once a year. More frequent changes may be necessary in harsh conditions.
Stop the engine immediately and let it cool down. Check the coolant level and ensure the radiator is not blocked. If overheating persists, have a professional inspect the cooling system.
To adjust the brakes, locate the brake adjusters near the wheels. Turn them clockwise to tighten or counterclockwise to loosen the brakes. Make sure the adjustment is even on both sides.
Ensure the brakes are functioning properly, check tire pressure and tread, verify the throttle and steering are responsive, and inspect lights and indicators. Always wear appropriate safety gear.
Remove the air filter cover, take out the filter, and clean it with compressed air or a non-flammable solvent. Allow it to dry completely before reinstalling. Replace if excessively dirty or damaged.
Check the tire pressure and ensure it's at the recommended level. Inspect the suspension for damage or wear. Tighten any loose steering components and consider re-aligning the wheels.
