1.The working medium of oil pump is hydraulic oil, and L-HM32 hydraulic oil is used in winter. L-HM46 hydraulic oil can be used in summer.
2.Keep the liquid level of the oil tank on the center line of the oil mark to prevent the oil pump from empty. When refueling, use the 120 mesh filter to remove impurities in the new oil. Usually, the oil tank is cleaned every two months, the filter is cleaned every half a year, and new oil is replaced at the same time.
3.Normal working oil temperature is 20 ℃ to 50 ℃, the oil temperature is too high, need cooling measures or stop pump, after waiting for the oil cooled sufficiently to work properly. If the oil temperature is too low, it is not allowed to work directly. The heating measures should be taken. The oil temperature can be raised through external heating or low-pressure operation.
4.The working pressure of the pump shall not be arbitrarily raised.
5. Long-term use of high pressure hose. Due to the aging of the hose, damage in various places will reduce the pressure strength of the hose,regular inspection should be noted.
