The recommended oil type for the CFMOTO CFORCE 400 is 10W-40, and the oil capacity is approximately 2.6 liters. Always refer to the owner's manual for the most accurate information.
To perform an oil change, first warm up the engine, then turn it off. Remove the oil drain plug and let the oil drain completely. Replace the drain plug and add new oil through the oil filler cap. Check the oil level with the dipstick to ensure it's correct.
The recommended tire pressure for the CFORCE 400 is 5 psi (34 kPa) for the front tires and 5 psi (34 kPa) for the rear tires. Always check the tire pressure when the tires are cold.
If the ATV won't start, check the battery for charge, ensure the fuel valve is open, and verify that the ignition switch is on. Also, inspect the spark plug for fouling or damage. If issues persist, consult a professional mechanic.
Routine maintenance includes checking and changing the oil, inspecting the air filter, checking tire pressure, lubricating the chassis, and ensuring all nuts and bolts are tight. Regularly inspect the brakes and coolant levels as well.
The CFORCE 400 features adjustable suspension. To adjust, locate the preload adjusters on the shocks. Use the appropriate tool to rotate the adjuster to increase or decrease the preload according to your riding preference and terrain.
If the ATV overheats, stop the vehicle and allow the engine to cool. Check the coolant level and refill if necessary. Inspect for leaks in the cooling system and ensure the radiator is not blocked. If the problem persists, seek professional help.
To replace the air filter, remove the seat and access the air filter cover. Remove the screws or clips holding the cover, take out the old filter, and replace it with a new one. Ensure the new filter is seated properly before reattaching the cover.
The CFMOTO CFORCE 400 is designed to run on unleaded gasoline with a minimum octane rating of 91 RON. Using the recommended fuel type helps maintain engine performance and efficiency.
To maintain the battery during storage, disconnect it from the ATV and store it in a cool, dry place. Use a battery maintainer or trickle charger to keep it charged. Check the battery periodically for charge levels and corrosion.
