3. Operating Instructions

The Mount-It! Full Motion TV Wall Mount provides flexible positioning for your television. Adjustments should be made carefully to avoid damage to the TV or mount.

  • Swivel: The articulating arms allow the TV to swivel 90 degrees left and right. Gently push or pull the TV to achieve the desired horizontal viewing angle.
  • Tilt: The mount supports a 15-degree downward tilt and a 10-degree upward tilt. This feature helps reduce glare and optimize viewing from different heights. Adjust the tilt by loosening the tilt mechanism, setting the angle, and then re-tightening.
  • Extension/Retraction: The arm can extend up to 17 inches from the wall for maximum flexibility and retract to 2.5 inches to save space. Gently pull the TV forward or push it back towards the wall.
  • Level Adjustment: After installation, a 3-degree rotation feature allows for minor post-installation level adjustments to ensure your TV is perfectly horizontal.
  • Cable Management: Utilize the built-in cable management clips on the arms to route and secure your TV cables, maintaining a clean and organized appearance.

4. Maintenance

To ensure the longevity and safe operation of your Mount-It! TV wall mount, follow these maintenance guidelines:

  • Regular Inspection: Periodically check all screws and bolts to ensure they remain tight. Loose connections can compromise stability.
  • Cleaning: Wipe the mount with a soft, dry cloth to remove dust. Avoid using abrasive cleaners or solvents, which may damage the finish.
  • Lubrication: The articulating joints are designed for smooth movement. If any stiffness occurs, a small amount of silicone-based lubricant can be applied to the moving parts, avoiding contact with the TV screen.
  • Weight Limit: Never exceed the maximum weight capacity of 77 lbs. Overloading can lead to structural failure and damage.

5. Troubleshooting

This section addresses common issues you might encounter with your TV wall mount.

  • TV is not level: Use the 3-degree rotation adjustment feature to fine-tune the TV's horizontal position. Ensure the wall plate itself was installed level.
  • Mount feels loose: Re-check all wall mounting bolts and TV attachment screws. Tighten any loose fasteners. If the issue persists, consult a professional installer.
  • Difficulty adjusting movement: Ensure no cables are snagged or obstructing movement. Check if any locking mechanisms (if present) are fully disengaged. Applying a small amount of silicone lubricant to the joints may help.
  • TV does not fit VESA pattern: Verify your TV's VESA pattern against the mount's supported patterns (75x75mm to 400x400mm). If your TV's pattern is outside this range, the mount is not compatible.
