7. Maintenance
Regular maintenance ensures the longevity and safe operation of your TV mount.
- Cleaning: Use a soft, dry cloth to wipe down the mount. Avoid abrasive cleaners or solvents.
- Check Connections: Periodically check all screws and bolts to ensure they are securely tightened. Loose connections can affect stability and safety.
- Lubrication: The moving parts are designed for smooth operation. Avoid applying lubricants unless specifically instructed by the manufacturer.
- Cable Management: Ensure cables are neatly organized using the provided straps to prevent strain on connections or entanglement.
8. Troubleshooting
If you encounter any issues, refer to the following common solutions. If the problem persists, contact customer support.
- Mount feels loose after installation:
- Ensure all wall mounting bolts are securely fastened into the studs or appropriate anchors.
- Verify the TV mounting screws are correctly tightened to the VESA plate.
- Confirm the wall type is suitable and not drywall alone.
- TV is not level:
- Use the built-in leveling adjustment (3 degrees left/right) to fine-tune the screen's horizontal position.
- Re-check the initial installation of the wall plate with a level.
- Movement (extension, swivel, tilt) is stiff:
- Ensure no cables are obstructing the movement of the arms.
- Verify the TV weight is within the specified load capacity.
- The mount is designed for smooth operation; avoid forcing movements.
- TV cannot rotate 90 degrees:
- Ensure there is sufficient clearance around the TV and mount for full rotation.
- Check for any physical obstructions (e.g., furniture, walls) preventing the rotation.
