Note: 1) pressures, the staff are not allowed in the work of more than 63MPa pressure, can not easily compete mobilize pressure valve. 2) work should firmly shaking handle, low pressure hand pump, the oil has an impact not cause the phenomenon, so that each valve for a long time to work. 3) reversing valve lever should be pulled slowly, manually pumping stations, lest damage parts. 4) When the oil is not enough to make up for oil, marine hand pump, it should be noted in the commutation of fuel oil storage tank, so as not to spill hydraulic oil. 5) high pressure hand pump at each link needs tightening may continue to work. 6) High-pressure hose EHV undergo an annual test to avoid unexpected hose aging. When the test pressure is less than 90Mpa outburst, when leaking hydraulic hand pumps can not be used should be wiped clean prior to use, hand pump, and should check the parts are flexible, without injury, when there is a load and avoid the quick connector unloading next, in order to avoid accidents and damage to components. This hydraulic Rama before use is to be highly valued. Hydraulic Lu (Figure), mine hand pumps, hand pumps provided by the Texas Lu of the hydraulic machinery plant.
