5. Setup and Installation
Before you begin, ensure you have the necessary tools (e.g., drill, level, screwdriver, stud finder) and understand all steps. It is recommended to have two people for installation, especially when mounting the TV.
5.1. Prepare the Wall
- Choose Location: Select a suitable location on your wall, considering viewing height and proximity to power outlets.
- Locate Studs (for wood stud walls): Use a stud finder to locate the center of two adjacent wooden studs. Mark these locations.
- Mark Drilling Points: Hold the wall plate against the wall at the desired height and use a pencil to mark the drilling points through the holes on the wall plate. Ensure the plate is level using a spirit level.
- Drill Pilot Holes:
- For wood studs: Drill pilot holes (e.g., 5.5mm / 7/32 inch) at the marked locations.
- For concrete/brick walls: Drill pilot holes (e.g., 10mm / 3/8 inch) and insert concrete anchors (if provided, otherwise purchase suitable ones).
5.2. Attach Wall Plate
- Align the wall plate with the drilled holes.
- Secure the wall plate to the wall using the provided lag bolts and washers. Tighten firmly, but do not overtighten.

5.3. Attach TV Brackets to TV
- Lay your TV face down on a soft, clean surface to prevent scratches.
- Identify the VESA mounting holes on the back of your TV.
- Select the appropriate screws, washers, and spacers from the hardware kit that fit your TV's VESA pattern.
- Attach the TV brackets to the back of your TV. Ensure they are securely fastened and evenly spaced.
5.4. Mount TV to Wall Mount
- With assistance, carefully lift the TV and hook the TV brackets onto the wall mount arm.
- Ensure the TV is securely seated on the mount. Some mounts have safety screws or locking mechanisms; engage these if present.
5.5. Install Adjustable Shelf
- Attach the shelf support arms to the main vertical post of the wall mount.
- Adjust the height of the shelf support arms to your desired position (between 316mm and 462mm from the base). Secure them with the provided screws.
- Place the glass shelf onto the support arms. Ensure it is stable and level.

6. Operating Instructions
The Maclean MC-771A mount offers flexibility for optimal viewing.
- Tilt Adjustment: To adjust the vertical tilt of your TV, loosen the tilt adjustment knobs/bolts on the TV plate, set the TV to the desired angle (+15° to -5°), and then re-tighten the knobs/bolts securely.
- Swivel Adjustment: The articulating arm allows you to swivel the TV left or right to achieve the best viewing angle from different positions in the room. Gently push or pull the TV to the desired angle.
- Distance from Wall: The articulating arm also allows you to extend the TV further from the wall (up to 375mm) or push it closer (down to 54mm) as needed.
- Shelf Use: The glass shelf can hold various media devices such as Blu-ray players, game consoles, or receivers, up to a maximum weight of 5 kg. Ensure devices are placed centrally and do not obstruct TV ventilation.
