The lift chair can't lift. How to fix it?

1. Align the chair and remove its base.

The swivel chair in the office is on a flat surface, so make sure it is in a horizontal position. Remove the fastening clips at the bottom of the seat, and then take off the base. If the foundation of the bolt or nut is fixed, it can be loosened and removed with a suitable wrench.

Step 2 check the indoor chairs

See if the chair is damaged. If other damaged parts appear, please refer to the instructions and replace them in the correct way.

3. Delete the existing cylinder.

Clamp the cylinder tube, open it and loosen the cylinder until it comes off easily. Be careful not to forcibly pull, otherwise it may damage other parts of the chair.

4. Install a new cylinder

Buy a new cylinder. Make sure to choose the right substitute.

5, reassembly

Tighten all bolts and nuts with a wrench, and then delete them. When the whole chair is reassembled, check whether the gas cylinder works normally by adjusting the height of the chair.
