6. There is water in the oil to form liquid-in-water (new oil needs to be replaced).
7. The oil pump suction pipe is leaking.
8. When the knife is automatically retracted, the parameters of the hydraulic crocodile shearing machine will not stop after hitting the stroke switch, and the stop button will not work.
