1. Look at the number of oil pipes replaced in the entire vehicle, the less it is, the newer the car is.
2. Whether the engine leaks oil, whether the excavator works normally when the throttle is increased, whether there is a lot of black smoke, whether there is any abnormal sound, and whether there is breath holding.
3. The power of the large pump and the engine are idling. If the body cannot be lifted, it is because the pump has no power or the engine sounds abnormally when it is lifted, indicating insufficient engine power. Increase the throttle and extend all cylinders to listen for any changes in the sound of the large pump.
4. Chain plate inspection. (This is relatively simple)
5. Check the gap between the left and right sides, up and down of the turntable. It is allowed to have some gap between the left and right sides, but it is not acceptable for the up and down sides.
6. Check the normal throttle working speed.
7. Check all oil cylinders for any scratches.
8. Walk inspection, lift up one side, and walk in high-speed mode with your ears close to the drive wheels to listen for any abnormal sounds.
