First of all, for the specific wear of the automatic feeding mixer, we should observe whether there are problems in the color and quality of the oil, observe whether there are iron chips on the surface, and check the oil viscosity. If there are a lot of iron chips in the engine oil, it means that the crankshaft bearing bush and connecting rod bush are seriously worn. If the oil is viscous, it means that the oil has not been replaced for a long time.
