　　1. After using the stage chain hoist, it should be cleaned and coated with rust proof grease, and stored in a dry place

　　2. Maintenance and overhaul should be carried out by those familiar with the stage manual hoist mechanism to prevent those who do not understand the performance principles of the machine from disassembling and assembling it at will.

　　3. Install the chain gear according to the drawing.

　　4. When installing the groove nut, the handwheel should be turned clockwise first to press the ratchet and friction plate onto the brake air seat before installing the groove nut.

　　5. After cleaning, inspection, and maintenance, the stage chain hoist should undergo no-load and heavy load tests to confirm normal operation, automatic reliability, and can only be used interchangeably.
