 2. press the button switch " up" until the chain is fully retracted into the chain bag and the motor stops running.

 3, check the lubrication of the lifting chain (Lifting chains are lubricated and oiled before they leave the factory, but may be dry during shipping ) in the process of transportation any ready-made lubricating oil can be used to lubricate the lifting chain, we also suggest to maintain a small amount of lubricating oil in the chain bag, let the chain can be dipped in lubricating oil.

 4, When the chain hangers of the host machine is double chain or multi chain, it is strictly prohibited to turn the hook from the chain in order to avoid danger.
