The recommended oil type for the Suzuki KingQuad 400ASi LT-A400F 2022 is SAE 10W-40, API service classification SF or SG.
It is recommended to change the oil every 3,000 miles or 6 months, whichever comes first. Regular oil changes help maintain engine performance.
The correct tire pressure for the front tires is 4.0 psi and for the rear tires is 4.0 psi. Always check tire pressure when the tires are cold.
First, check the battery connections for corrosion or looseness. Then, inspect the ignition switch and fuses for any visible damage. If the problem persists, consult a professional technician.
During the first 10 hours of operation, avoid full-throttle starts and high-speed operation. Gradually increase speed and engine load. This helps ensure proper engine seating and performance.
The KingQuad 400ASi features adjustable rear shock absorbers. Use the preload adjuster to change the spring tension according to your weight and riding conditions. Refer to the owner's manual for specific instructions.
If the engine overheats, stop the ATV immediately and allow it to cool. Check the coolant level and look for any visible leaks. If the problem persists, consult a qualified technician.
Remove the air filter cover and take out the filter. Clean it with compressed air or replace it if it’s too dirty. Ensure it is completely dry before reinstalling. Regular maintenance can improve engine efficiency.
Signs include squeaking or grinding noises, reduced braking performance, or a spongy brake lever. Inspect the brake pads and fluid levels regularly and replace them as needed.
To store the ATV for winter, clean it thoroughly, change the oil, fill the gas tank, and add a fuel stabilizer. Disconnect the battery and store it in a cool, dry place. Cover the ATV to protect it from dust and moisture.
