4.1. Wood Stud Installation
- Locate Studs: Use a stud finder to locate the edges and center of the wood studs where you intend to mount the TV. Mark the center of the studs at your desired TV height.
- Position Wall Plate: Hold the wall plate against the wall, aligning it with the marked stud centers. Use the integrated bubble level to ensure the plate is straight. Mark the center of the four mounting holes on the wall.
- Drill Pilot Holes: Using a 3/16 inch (4.5 mm) drill bit, drill pilot holes at the marked locations.
- Secure Wall Plate: Attach the wall plate to the wall using the provided lag screws and washers. Tighten until secure.

4.2. Concrete / Brick Wall Installation
- Position Wall Plate: Hold the wall plate against the concrete or brick wall at your desired TV height. Use the integrated bubble level to ensure the plate is straight. Mark the center of the six mounting holes on the wall.
- Drill Pilot Holes: Using a 3/8 inch (10 mm) masonry drill bit, drill pilot holes at the marked locations to a depth of approximately 2.4 inches (60 mm).
- Insert Anchors: Clear any dust and debris from the drilled holes. Insert the provided concrete anchors into the holes.
- Secure Wall Plate: Attach the wall plate to the wall using the provided lag screws and washers. Tighten until secure.
4.3. Attaching TV Brackets to TV
- Align Brackets: Align the TV brackets over the VESA holes on the back of your television.
- Select Hardware: Choose the appropriate size mounting bolts and washers for your TV's VESA mounting holes.
- Secure Brackets: Attach the TV brackets to the TV using the selected hardware. Ensure they are securely fastened.
- (Optional) Use Extension Brackets: If your TV's VESA pattern exceeds the standard bracket width, remove the nuts from the extension brackets. Place the extension brackets onto the ends of the TV brackets and reinstall the nuts to secure them in place. This allows compatibility with VESA patterns up to 800x600mm.

4.4. Attaching TV to Wall Plate
- Hook TV: Carefully lift the TV and hook the top of the TV brackets onto the top edge of the wall plate.
- Lower TV: Slowly swing the TV downwards until the TV brackets are fully seated and lowered onto the wall plate.
- Secure Safety Bolts: Tighten the safety bolts located on the underside of both TV brackets until the bolt is past the lip of the wall bracket. This prevents accidental dislodgement.

6. Maintenance
Regular maintenance ensures the longevity and safety of your TV mount.
- Periodically check all screws and bolts to ensure they remain tight.
- Clean the mount with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Inspect the mount for any signs of wear or damage. If damage is found, contact customer support.
7. Troubleshooting
If you encounter any issues during or after installation, refer to the following common solutions:
- TV is not level: Ensure the wall plate was installed level. If the wall plate is level, check that the TV brackets are evenly secured to the TV. Slight adjustments can sometimes be made by loosening and re-tightening the TV bracket bolts.
- TV feels unstable: Recheck all mounting bolts on both the wall plate and the TV brackets to ensure they are securely tightened. Verify that the wall structure is appropriate for the mount and TV weight.
- Difficulty with tilt adjustment: Loosen the tilt adjustment knobs sufficiently before attempting to change the angle. Ensure no cables are obstructing the movement.
