5. Maintenance
To ensure the longevity and optimal performance of your SANUS TV wall mount, follow these simple maintenance guidelines:
- Regular Cleaning: Dust the mount periodically with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as they may damage the finish.
- Check Connections: Periodically inspect all screws and bolts to ensure they remain tight. Over time, vibrations or frequent adjustments may cause them to loosen.
- Lubrication: The articulating joints are designed for smooth operation and typically do not require lubrication. If you notice any stiffness, contact customer support for advice.
