Generally speaking, after a long time of use, the hydraulic paper cutter may basically have oil leakage. Although the paper cutter can work normally when the oil leakage failure occurs, the oil consumption of the hydraulic paper cutter will cause fuel consumption. Increase, causing waste.

        The repair of the oil leakage of the hydraulic paper cutter requires the replacement of the hydraulic valve and other skeleton oil seals of other parts, and the oil leakage problem can be solved after the replacement. However, after many users have changed, the oil leakage of the hydraulic paper cutter still exists, and the expected solution effect is not achieved. This is mainly because the quality of the replaced seals does not meet the standards, and these seals that do not meet the standards Mainly because the inventory time is too long, it has deteriorated and aging, so replacing these sealing rings can easily cause the cutter to leak again, thus affecting the sealing effect of the cutter. Therefore, you should pay attention to the quality of the sealing ring when replacing its sealing ring, so as to avoid repeated leakage of oil.
