What is the detailed explanation of the fault light on LiuGong 850h?
4 Answers
LiuGong 850h fault light detailed explanation is that if the engine is kept in a turbocharged state for a long time at high power, the temperature of the coolant is difficult to effectively reduce, thus displaying high coolant temperature. The following is more information about the engine oil pressure warning light: 1. It serves as a warning: If the engine oil pressure warning light comes on during normal vehicle operation, pay attention to check whether the engine is short of oil. 2. Reasons why the oil pressure fault light stays on: (1) The engine oil storage is too low, causing the lubrication system to have no oil or insufficient oil, resulting in low oil pressure; (2) The oil is too dirty or viscous, causing the oil pump to fail to effectively suck and pump out oil, resulting in low or no oil pressure; (3) The oil is thin or becomes thin due to high engine temperature, leaking from the friction gaps of the engine, resulting in low oil pressure; (4) Oil pipe leakage, oil pump damage or excessive wear of its components leads to reduced or no oil suction and pumping, resulting in low or no oil pressure; (5) The gap between the crankshaft and the bearing bush exceeds the standard, causing oil leakage and resulting in low oil pressure.
As a seasoned driver of the Liugong 850H, let me break down the warning lights in detail. A common engine fault light usually indicates issues like poor fuel supply, sensor problems, or abnormal exhaust—promptly inspect the fuel system and electronic control system. If the oil pressure light comes on, it signals insufficient oil or pump failure; stop immediately to prevent engine damage. A flashing temperature warning light means coolant overheating—check the fan and radiator for blockages. The battery light warns of charging faults—inspect the alternator belt and connections. The hydraulic system light indicates pressure loss—quickly check hydraulic oil levels and lines. Avoid sudden starts and stops during operation, and make it a habit to scan the dashboard before starting. Never ignore warning lights and continue working—safety first, always seek professional repairs. Regular oil changes and sensor maintenance can prevent 90% of issues and extend machine lifespan.
When I first started operating the LiuGong 850H, the warning lights always confused me, but now I've got the hang of it. An illuminated engine light could mean low fuel, an electrical short circuit, or dust triggering a false alarm. If the oil pressure light comes on, stop immediately and check the dipstick—top up if it's low. When the high-temperature light is on, reduce the load, open the windows for ventilation, and don't let the engine overheat. A flickering battery light might indicate poor contact—try tightening the battery terminals. Don't panic when issues arise; refer to the manual or search the fault code on your phone to roughly locate the problem. Beginners should pay close attention to dashboard changes and report persistent lights for repair instead of randomly dismantling parts. For maintenance, clean dust and inspect wiring monthly to reduce false alarms. Operating machinery is all about attention to detail—safety comes first.
The fault lights on the LiuGong 850H are like alarm signals, and here's a simple interpretation: The engine icon indicates issues with the fuel pump, injectors, or air filter; the oil drop symbol warns of low oil pressure; the flashing thermometer signals cooling system problems, such as a stuck fan or faulty thermostat; the battery light suggests a generator failure or loose wiring; and the hydraulic light indicates cylinder leaks or pump failure. Diagnosis can be done by connecting a computer to read fault codes, but ordinary people can determine the direction by observing symptoms: if a light is on, stop to check fluid levels and appearance. Minor repairs like replacing filters can be done yourself, but major issues should be reported to a service station. Note: never ignore any warning lights, as delaying repairs can easily increase damage costs.
