500h replace engine oil and engine oil filter element; 1000h replace the hydraulic oil filter element and rotary reducer oil. If there is a corrosion-resistant filter element (water filter), replace it together. 1500h is basically the same as 500h. 2000h replace the hydraulic oil and the oil of traveling reducer. 4000H replace antifreeze. Strictly speaking, the diesel filter element should also be replaced at 500h. However, depending on the quality of diesel used, the replacement time is uncertain. Usually, when the engine power drops slightly, or the car is a little suffocated, it can also be replaced when there is black smoke. Then clean the air filter element every 250h.
