500H replacement engine oil and oil filter element; 1000H replacement hydraulic oil filter element, rotary reducer engine oil, if there is corrosion-resistant filter element (water filter) also have to be replaced together. 1500H is basically the same as 500H. 2000H Replace hydraulic oil and travel reducer oil. 4000H Replace antifreeze. The diesel filter element should strictly be replaced by 500H, but according to the quality of the diesel used, the replacement time is also uncertain.
