Steps:

- Carefully insert the cylinder, ensuring it fits securely.
7) Test the Cylinder's Functionality:
- Use the chair's lever to test the new cylinder's functionality. Ensure that it can adjust smoothly and hold its position.
- Remove the cover of the tilt mechanism to expose the top of the cylinder.
- Adjust the black pin using a hexagonal screw head to ensure it is horizontal for proper function.
8) Reassemble the Chair:
