The pressure plate cannot rise or press down in manual or automatic

mode:

① Is the motor direction correct: If the motor direction is opposite, please reconnect the two power cords.

② Is the oil pump working properly: Checkwhether there is convection in the oil tank when the oil pump is working. Ifthere is no convection, it proves that the oil pump is damaged.

③ Is the overflow valve (pressure regulating valve) blocked: Loosen the parts

of the overflow valve and clean them carefully. There are small working holes

in the overflow valve. If there are debris in the hydraulic oil, it is easy to block

the small working holes and cause the machine to not work or have no

pressure (Note! The overflow valve is generally not easily damaged, but there

are more blockages).
