Preparation for the procedure:

1. It is strictly forbidden to dismantle the jack with pressure. When the jack is tested or loaded, the staff should stand on both sides, the station is forbidden in the direction of the end face, and the protective device should be provided in the dangerous section.

 

2. All people who enter the use of the jack should do “the oil pump rings and the jacks clear the ends”. On the one hand, avoid pulling the sliding wire to hurt people, on the other hand, avoid accidentally operating the jack parts to fly out and hurt people.

 

3. “When the oil pump is turned on, the pump personnel must not leave”. Always pay attention to the oil meter values. When returning, if the fuel gauge is boosted rapidly, stop the pump immediately.

 

4. The oil used for the jack is passive oil, which is affected by the oil of the oil pump. It is best to use No. 10 oil, and No. 20 oil is allowed in summer. High quality, low viscosity mineral oils can also be used. The oil is kept clean and must be filtered when the oil is poured into the oil pump.

 

5. The tubing must be cleaned before connecting the tubing, especially the nozzle.

 

6. The jack should be operated 3-5 times at no load before use to eliminate the air in the chamber.

 

7. During the working process of the jack, the loading should be stable, the unloading should be slow, and the sliding wire should be avoided.

 

8. After the work is completed, the piston returns to the position. Always wipe and keep it clean.

 

9. The jack is faulty, and it is repaired by someone with certain professional knowledge, or returned to the factory for repair.

 

10. When parking in the park or in storage, the nozzle should be equipped with a dust cap to prevent dirt and rust.
