1.The pneumatic hoist should be placed in a relatively dry location and also in a relatively safe location, which can effectively prevent damage to the outer shell of the hoist.

2.The power supply of the hoist should also be protected. Effective insulation protection can avoid the phenomenon of electric leakage in the hoist after not using it for a long time. This is not only to maintain the pneumatic hoist, but also to improve the safety of users.

3.After each use, the gourd should be wiped clean to avoid any water stains on it, and the chain should be cleaned to ensure that the machine is in a dry state before storing it, otherwise corrosion may occur easily.

4.The maintenance of the chain is also important. Due to the high humidity and salinity of the coastal air, it is easy to cause rust and corrosion of the lifting chain. Therefore, it is necessary to maintain good surface lubrication of the chain at all times. The lubricating oil can be 40 'mechanical oil, while also avoiding sand and dust adhesion caused by excessive viscosity.
