Maintenance
Proper care will ensure the longevity and appearance of your chair.
- Cleaning: The PU leather surface is easy to clean. Wipe with a damp cloth and mild soap solution. Avoid harsh chemicals or abrasive cleaners.
- Regular Inspection: Periodically check all screws and bolts for tightness. Re-tighten if necessary to prevent wobbling or instability.
- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
- Avoid Overloading: Do not exceed the maximum weight capacity of 264 lbs.
Troubleshooting
If you encounter any issues with your chair, refer to the following common problems and solutions:
- Chair does not adjust height: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift may need replacement.
- Chair wobbles: Check that all assembly screws, especially those connecting the mechanism to the seat and the armrests, are securely tightened.
- Casters do not roll smoothly: Inspect casters for trapped debris (hair, lint) and clean them thoroughly. Lubrication may be applied if needed.
- Reclining function is stiff or not locking: Check the reclining lever for any obstructions. Ensure the mechanism is clean and free of debris.
- Squeaking noises: Apply a small amount of silicone lubricant to moving parts, especially around the gas lift and reclining mechanism.
If these solutions do not resolve the problem, please contact HOMCOM customer support.
