The pipe equipment is maintained once a month or so. The maintenance contents are as follows:

1. Check the solid parts of each part to make them in a solid state.

2. Each joint of the hydraulic station is equipped with oil-resistant rubber sealing ring. If the sealing ring is damaged or leaks, it should be replaced in time.

3. If the forward and backward failures are found, first check whether the electro-hydraulic reversing valve is operating. If the electro-hydraulic reversing valve is operating normally, check whether the electromagnetic overflow valve or single-phase unloading valve is stuck by impurities. (This phenomenon is generally easy to occur when the device is started to use). If there is a jam, disassemble it and clean it with gasoline or diesel and reinstall it.

4. Clean the oil tank and filter the hydraulic oil once within 15 days after the equipment is used.

5. When cleaning the fuel tank, clean the oil inlet filter in the fuel tank.
