Step 2: Attach the Desk Legs to the Frame

Secure the desk legs to the main frame using the provided screws and Allen key. Ensure all screws are tightened for stability. Insert the other end of the transmission rod into the slot on the leg, rotating it slightly if needed for proper installation. Secure the transmission rod by tightening the pre-assembled set screw using the small Allen key.

Step 3: Assemble and Attach the Desktop

If your desktop comes in multiple pieces, use the wooden dowels and metal plates to join them securely. Once assembled, carefully place the desktop onto the leg frame. Align the pre-drilled holes and secure the desktop to the frame using the provided screws. Attach the cable management hooks to the underside of the desktop.

Step 4: Connect the Cables

Connect the motor cable, control panel cable, and power adapter cable to the main control box. Ensure all connections are firm. Use the provided cable ties and clips to manage and secure the cables neatly along the desk frame, preventing them from dangling or getting caught.

Step 5: Final Touches

Insert the cable grommets into the desktop holes for a clean finish. Plug the power adapter into a wall outlet. Your desk is now ready for initial setup and operation.
