Troubleshooting of hydraulic press
| phenomenon | reason | Troubleshooting |
| The lifting plate does not rise during work or the pressure drops significantly during pressure maintenance | There is dirt or damaged oil seal inside the high-pressure pump | Cleaning or replacement |
| There are dirt, wear, or damaged oil seals in the control valve | Grind or replace | |
| Reverse rotation of oil pump | Reconnect the motor wire | |
| The safety valve is not properly adjusted | Adjust the safety valve properly | |
| Insufficient oil in the fuel tank | Add sufficient oil | |
| Unstable pressure or crawling phenomenon | Unclean oil or pump/valve | Replace the oil or disassemble the pump valve for cleaning |
| There is air in the oil or pipeline | Empty trips several times | |
| Damaged oil seal in high-pressure pump or control valve | replace | |
| Insufficient oil causes the oil pump to become empty | Add sufficient oil | |
| Oil leakage | Oil seal damaged, screw plug not tightened | Tighten the screw plug |
