After the installation and debugging of the pneumatic hoist, the following operations should be carried out before the formal operation to ensure that the hoist operates normally and safely. And regularly carry out maintenance to extend the service life of the pneumatic hoist and improve work efficiency.

1. When using the pneumatic hoist, it must be equipped with a dedicated air compressor to ensure that the compressed air used as the power source remains clean and dry. And use a specialized filtering and lubrication device, and then firmly connect the air pipe to the hoist.

2. Before using the pneumatic hoist, the operator must conduct a specified inspection and add a small amount of lubricating oil (20ml) to the air inlet of the motor to provide better lubrication effect. Check if there is any oil leakage in the hoist motor and gearbox.

3. Before using the pneumatic hoist, check whether the chain, hook, and limiter are intact.

4. Before starting the operation of the gourd, run it under no load for 5 minutes to confirm that all components and structures are normal; When lifting heavy objects, first lift them to a height of 30cm above the ground and apply brakes to ensure the safety and reliability of the brakes.

5. After use, the pneumatic hoist should be placed on a dedicated gantry frame, with the chains intertwined. The controller air pipe should be coiled neatly and fixed on the transportation frame. Do not place hooks, chains, etc. on the air duct.

If there is a malfunction during the use of the hoist, it should be stopped immediately, reported for repair in a timely manner, and the pneumatic hoist should be strictly disassembled and modified without authorization.
