1. Hydraulic tank pressure and volume control tank should pay attention to the tank pressure at all times during work. The pressure must be kept within the range specified in the “User Manual”.
2. The pressure is too low, the oil pump is not easy to damage due to insufficient oil absorption. If the pressure is too high, the hydraulic system will leak oil, which will easily cause the low pressure oil circuit to burst. For the equipment after maintenance and oil change, after exhausting the air in the system, check the oil level according to the random “Operating Instructions”, put the machine in a flat place, and re-check the oil level after the engine after turned off for 15 minutes and added the oil when it needed.
3. Other Notes：In the work, it is necessary to prevent flying stones from hitting hydraulic cylinders, piston rods, hydraulic oil pipes and other components. If there is a small impact on the piston rod, the surrounding edge should be ground with oil stone in time to prevent damage to the piston rod sealing device and continue to be used without oil leakage. For equipment that has been continuously shut down for more than 24 hours, oil must be injected into the hydraulic pump before starting to prevent the hydraulic pump from being dry and damaged.
4. Regular maintenance Notes：At present, some engineering machinery hydraulic systems are equipped with intelligent devices, which have some hidden warning functions for the hydraulic system, but their detection range and degree have certain limitations, so the inspection and maintenance of the hydraulic system should be intelligent device detection results and periodic inspections and maintenance combined.
5. Maintenance Check the filter screen attachments, such as excessive metal powder, often marks the wear of the pump or the cylinder of the cylinder. To do this, you must ensure that the corresponding measures are taken before starting. If the filter is found to be damaged, the dirt will accumulate, and it should be replaced in time. If necessary, change the oil at the same time.
