How to deflate the lift chair

The online deflation video can be referenced, and I succeeded in deflation after referring to it.

Raise it to the highest position, otherwise it will rise when the ejector pin deflates. Use a little force when pulling the white twist; The thimble is a little troublesome to lift. Usually, the thimble can be lifted by white twisting, but the deflation should not only dive, but also be pushed in, so I need to find something thicker or thinner than the thimble, so I change the knife with a small cross. Control the strength, push the thimble slowly, and then the sound of the "pool" is a little louder, which means that you are a little deflated and a little scared when you let it out. Play it a few times more, and the "pool" sound will become smaller and smaller. When it is almost played, the thimble will fall in. I can't help it. There is no high pressure in it.
