Sometimes, cutting machine, bending machine pressure is not enough, I do not know if the hydraulic pump is broken, how should I judge?!
If it is, sometimes the pressure is not enough, not often. Then I don't think the oil pump is likely to go bad.The main reason is the hydraulic valve or oil above.
Touch the oil, step inside to see if there is any sense of oil absorption.
If it is winter, may be relatively thick oil, if it is not possible oil problems, there may be the problem of voltage, if it is the problem of the pump, it will not be less pressure is so simple. Where can you find someone to see?.
