Because in the beginning of the operation is easy to be affected by air bubbles and dust, high temperature bad lubrication or use condition overload, so that the hydraulic pump out of abnormal sound.
5 pay attention to the pressure gauge display value of the hydraulic circuit of the excavator at any time.
6 understand the function of each valve inside the hydraulic pump system of the excavator.
7 when changing the pump, should we pay attention to whether there is obstruction in each oil filter in the oil circuit of the excavator hydraulic system?
8 excavator regularly check the use of hydraulic oil, basically every one or two months to analyze whether the hydraulic oil of the excavator is deteriorating, whether there is discoloration or contamination.
