6. Troubleshooting
If you encounter any issues with your COLAMY Office Chair, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not adjust height. | Gas lift cylinder malfunction or lever not engaged. | Ensure the height adjustment lever is fully pulled. If the issue persists, the gas lift may need replacement. |
| Chair makes noise (squeaking/creaking). | Loose fasteners or friction between components. | Tighten all screws and bolts. Apply a small amount of silicone lubricant to moving parts if necessary. |
| Chair feels unstable or wobbly. | Loose connections or damaged base/casters. | Check and tighten all assembly screws. Inspect the star base and casters for any damage. |
| Difficulty reclining or locking tilt. | Tilt mechanism not engaged or tension knob too tight/loose. | Ensure the tilt lock lever is in the correct position. For auto-tension, verify the mechanism is functioning freely. |
