(2) Before working, make a test run for 10 minutes in an empty stroke, check whether the buttons, switches, valves, limit devices, etc. are flexible and reliable, confirm that the pressure of the hydraulic system is normal, and the working beam moves flexibly before starting to work.
(3) It is strictly forbidden to use the cylinder over stroke.
(4) If the cylinder piston is found to be vibrating or the oil pump makes a sharp sound, the gas must be discharged.
(5) If the equipment has abnormal phenomena or sounds during work, it should be stopped for inspection.
(6) When working, the pressed workpiece should be placed in the middle of the work table and be concentric with the spindle, and the pad should be placed smoothly.
(7) When the work is finished, the working oil pump should be turned off first, then the control oil pump should be turned off, the power supply should be cut off, the equipment should be cleaned, and the inspection records should be made.
