1. The oil pump uses No. 20 engine oil.

2. The oil storage capacity must be within the range above the oil window.

3. Every time refueling or changing oil, it is necessary to filter it with an 80 mesh or higher oil filter, and the oil tank must be cleaned before replacement. The oil change period is six months.

4. The working oil temperature ranges from 10 degrees Celsius to 50 degrees Celsius.

5. Before starting the electric pump, open the air release nut and place the switch in the unloading position.

6. If the motor temperature is too high during the process, it should be stopped. Cool it down before reuse.

7. The hydraulic pump has been scheduled before leaving the factory, and it is not allowed to raise the pressure arbitrarily. When it needs to be re scheduled, it must be stopped with the help of a pressure gauge.

8. The high-pressure oil pipe enters the factory and undergoes a 105MPA test. However, due to the random leakage and aging of the rubber hose, users need to check it regularly, which is usually six months. The vortex flowmeter is frequently used for three months, and the 87.5MPA pressure test is conducted during inspection. If there is any damage, protrusion, or leakage, it cannot be reused repeatedly.

9. Bearings are also washed once every six months, and lubricating grease needs to be added during assembly.
