5. Maintenance
Proper care will extend the life and appearance of your recliner.

- Moving Parts: Periodically check the reclining mechanism and swivel base for smooth operation. Do not force any moving parts.
6. Troubleshooting
If you encounter any issues with your recliner, refer to the following common solutions:
- Recliner not operating: Check if the power adapter is securely plugged into both the chair and the wall outlet. Ensure the power switch (if present) is in the ON position. Verify all internal electrical connections are properly matched and secure.
- Massage/Heat not working: Confirm the remote control is properly connected to the chair. Check the power connection. Try pressing the 'Power' button on the remote to activate the system.
- Unusual noises during operation: Inspect the reclining mechanism for any obstructions. Ensure all assembly bolts are tightened. If the noise persists, discontinue use and contact customer support.
