According to Honggang's 17 years of experience, when this happens, we must first judge the speed of the automatic descent to determine the problem.
The descending speed is slow, and the judgment time is several hours for the pressure plate to descend to the end. In this case, it is basically judged that the aging of the oil seal causes oil leakage in the cylinder. Solution: Replace the oil seal.
The descending speed is very fast, and the judgment time is several minutes or ten minutes. In this case, the solenoid valve failure usually causes the machine circuit and oil circuit failure. Solution: Clean or replace the solenoid valve.
