Daily maintenance items of Hydraulic Punching Machine ( 2 )

4. Check the hydraulic pipeline and gas circuit every day for leakage, whether the pressure is normal, and whether the water cooling is good. Check whether the outer skin of the high-pressure hose is intact, whether there is pull-off near the joint, and replace it in time if necessary to avoid cracking.

5. The oil of the Hydraulic Punching Machine should be strictly filtered before being added to the fuel tank, and the amount of oil in the fuel tank should not be lower than the requirements of the oil standard.

6. The oil temperature must not exceed 50°C, otherwise the system will be damaged. For equipment that is not used for a long time, the piston rod of the oil cylinder must be retracted into the oil cylinder to prevent corrosion.
