4.2 Installation Steps
- Locate the existing attachment point: Identify the worn, damaged, or stripped attachment piece on your mamaRoo Toy Arm.
- Remove the old piece: Carefully remove the existing attachment piece. You may need a screwdriver if it is secured with screws. The screws from the old piece should be retained for reuse.
- Insert the new attachment point: Place the new TEYOUYI attachment point into the designated slot on the mamaRoo Toy Arm. Ensure it aligns correctly.
- Add the spacer (if necessary): The package includes a spacer. Depending on the fit, you may need to use this spacer to ensure the toy bar is secure and does not rotate freely. The thick side of the spacer should face the toy arm.
- Secure the piece: Re-insert any screws that were removed from the old piece to secure the new attachment point firmly. Ensure it is a tight fit to prevent future drooping.

5. Operating Instructions
Once the replacement attachment piece is securely installed, the mamaRoo's toy bar should be restored to its intended position, allowing the mobile to function correctly without drooping. No specific operational steps are required for the attachment piece itself, as it serves as a structural component.
6. Maintenance
The TEYOUYI Mobile Attachment Connector Piece is made from durable plastic. To ensure its longevity:
- Cleaning: Wipe with a damp cloth as needed. Avoid harsh chemicals.
- Inspection: Periodically check the attachment point for any signs of wear, cracks, or loosening.
- Gentle Handling: While rugged, avoid excessive force when attaching or detaching the toy bar to prevent damage to the attachment piece or the mamaRoo itself.
