Maintenance
Regular maintenance will help keep your HOMCOM office chair in optimal condition:
- Cleaning: Wipe clean with a damp cloth. For faux leather surfaces, use a mild soap solution if necessary, then wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to prevent wobbling or instability.
- Casters: Clean any hair or debris from the casters regularly to ensure smooth rolling.
- Storage: If storing the chair for an extended period, keep it in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
If you encounter any issues with your chair, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair wobbles or feels unstable. | Loose screws or improper assembly. | Check and tighten all assembly screws. Ensure the gas lift is fully seated in the base. |
| Chair does not adjust height. | Gas lift malfunction or lever not engaged. | Ensure the height adjustment lever is fully pulled. If the issue persists, the gas lift may need replacement. |
| Massage/heating function not working. | Power connection loose, remote batteries low (if applicable), or unit malfunction. | Check that the power adapter is securely plugged into the chair and the wall outlet. Ensure the remote control is connected. If the remote uses batteries, replace them. |
| Casters not rolling smoothly. | Debris (hair, lint) caught in casters. | Turn the chair over and carefully remove any debris from the caster wheels. |
If these solutions do not resolve the issue, please contact HOMCOM customer support for further assistance.
