3. Maintenance
Proper maintenance will extend the life and performance of your COMHOMA Office Chair.
- Cleaning: Wipe clean with a damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these may damage the mesh or fabric.
- Regular Checks: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
- Caster Care: Keep the casters free of debris (hair, dust, etc.) to ensure smooth rolling. Clean them regularly with a soft brush or cloth.
- Gas Lift: The SGS class-3 gas lift is designed for long-term safety and smooth operation. If you experience issues with height adjustment, ensure the lever is fully engaged.
4. Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair is wobbly or unstable. | Loose screws or connections. | Tighten all assembly screws, especially those connecting the seat to the mechanism and the armrests. |
| Difficulty adjusting seat height. | Gas lift not engaging properly or faulty. | Ensure the height adjustment lever is fully pulled up or pushed down. If the issue persists, the gas lift may need replacement (contact support). |
| Casters not rolling smoothly. | Debris caught in casters or worn out. | Remove any hair or debris from the caster wheels. If still an issue, consider replacing the casters. |
| Chair makes squeaking noises. | Loose connections or friction between parts. | Tighten all screws. Apply a small amount of silicone-based lubricant to moving parts if necessary. |
