    First, the hydraulic system of the angle machine.
    1. The working medium of the oil pump is hydraulic oil, and l-hm32 hydraulic oil is used in winter. L-hm46 hydraulic oil can be used in summer.
    2. The liquid level of the oil tank shall be kept on the center line of the oil standard to prevent the oil pump from sucking empty. During refueling, 120 mesh filter screen shall be used to filter out the impurities in the new oil. When it is often used, the oil tank is generally cleaned every two months, the oil filter is cleaned every six months, and the new oil is replaced at the same time.
    3. The normal working oil temperature is 20 ℃ - 50 ℃. When the oil temperature is too high, cooling measures need to be taken or the pump needs to be stopped. It can work normally only after the oil is fully cooled. When the oil temperature is too low, it is not allowed to work directly. Heating measures need to be taken. The oil temperature can be increased by external heating or low-pressure operation.
    4. The working pressure of the pump shall not be increased arbitrarily
    5. The high-pressure hose is used for a long time. Due to the aging of the hose, the damage everywhere will reduce the compressive strength of the hose. Pay attention to regular inspection.
    Second, the air source triplet (water separation air filter, pressure reducing valve and oil mist).
    First, determine whether the components connected to the rear end of the air source triplet are oil-free components. If so, triplet shall not be used, but triplet shall be used. That is: cancel the oil mist. Then select the corresponding triplet according to the system pressure and the required flow. When not in use for a long time, the pressure should be adjusted to zero. Otherwise, the long-term fatigue of the spring will affect the service life. If the water distribution air filter is drained manually, the ponding shall be checked regularly and drained.
    In use, water shall be discharged to the water separation gas filter in time to ensure that the gas is dry; Pay attention to the oil quantity of the oil mist in use, and add oil when the oil quantity is insufficient
