Reinstallation instructions for automatic inflatable device of inflatable life jacket:

1. Unscrew the used CO2 cylinder counterclockwise and throw it away.

2. Put the hand-pulled inflatable rod into the inflatable part and install a new green indicator block to protect the inflatable rod from being pulled by mistake as much as possible. 3. check the holes and gaskets of the inflator connected to the CO2 cylinder liner. If damaged, replace the gasket again.

4. Take out the melted dissolving plug in the valve body and throw it away, then wipe the water in the valve body dry, put in a new dissolving plug, and tighten the big nut.

5. Check the mouth surface of the new CO2 cylinder to ensure that it is smooth, there are no signs of damage or abrasion, and the cylinder has a gross weight mark. You can use a small scale to weigh him and then compare his actual weight with the standard weight. If it does not match, please change it.

6. Screw the new cylinder clockwise into the body of the inflation part and tighten. But not too tight, in moderation.

7. Before each use, check the indicating parts installed on the inflatable parts. It will indicate whether you can use it. In addition, check the bottle mouth regularly to ensure that it is not punctured.
