5. Troubleshooting
If you encounter any issues with your chair, please refer to the following common troubleshooting tips:
- Chair Squeaks: Check all connection points, especially where the seat and backrest attach to the mechanism, and where the gas lift meets the base. Tighten any loose screws. A small amount of silicone lubricant can be applied to moving metal parts if the squeaking persists.
- Chair Does Not Adjust Height: Ensure the height adjustment lever is fully engaged. If the gas lift cylinder is not functioning, it may require replacement.
- Chair Feels Unstable: Verify that all casters are securely inserted into the five-star base and that all bolts are tightened. Ensure the chair is on a flat, even surface.
- Casters Not Rolling Smoothly: Remove any hair or debris wrapped around the caster wheels. Clean the wheels and their axles.
