1, overload each hydraulic lift has its own rated load, once the overload lifting, it will show the phenomenon of lifting weak or not up, reduce the load so that it can solve this problem in the load scale.
2, the hydraulic oil is insufficient, the solution is to add enough hydraulic oil
3. The circuit is open, and the solution is to check the button contactor and fuse, etc.
4. The supporting valve or electromagnetic reversing valve fails to act A, and the input voltage of electromagnetic coil is less than 220V. B, electromagnetic coil burned c, valve core stuck. The solution is to repair or replace.
5, manual pump, gear pump serious oil leakage, the solution to change the oil pump sealing ring.
6, the filter is blocked, the solution is to change or clean.
7, the gear pump is damaged, the oil without pressure, can be changed through the process of gear pump to achieve.
8. The one-way valve of the manual pump is stuck and fails to return. The solution is to unscrew the bolt of the valve port of the oil pump, overhaul and clean the hydraulic oil.
