5. Setup and Installation
Follow these steps to replace the mobile attachment connector piece on your 4moms mamaRoo Model 1037.
- Verify Model Number: Before proceeding, locate the model number on the bottom of your mamaRoo base. This replacement part is exclusively for 4moms mamaRoo Model 1037.
- Remove Existing Part: If an old, damaged attachment piece is present, carefully remove it. This typically involves unscrewing it from the mamaRoo's toy arm connection point. A Phillips head screwdriver may be required.
- Prepare the New Part: The package includes a toy bar attachment point and a spacer. The spacer has a "Thick Side" and a "Thin Side." Ensure you understand the orientation for proper fit.
- Install the Attachment Point and Spacer: Insert the new toy bar attachment point into the designated slot on the mamaRoo's frame. Then, position the spacer as needed to ensure a snug fit for the toy bar. The goal is to lift the removable toy bar back to its original, elevated position.
- Secure the Toy Bar: Once the attachment point and spacer are in place, reattach the mamaRoo's toy bar. Ensure it fits securely and does not droop. The fit should be tight to prevent future sagging.

6. Operating
After successful installation, the mamaRoo's mobile should be securely positioned and function as intended. The replacement part does not alter the electronic operation of the mamaRoo swing itself, only the physical attachment of the toy bar.
7. Maintenance
- Clean the attachment piece with a damp cloth and mild soap as needed. Avoid harsh chemicals.
- Ensure the attachment point remains free of debris or obstructions that could affect its fit.
- Periodically check the tightness of any screws used during installation to ensure the toy bar remains secure.
8. Troubleshooting
8.1 Toy Bar Still Droops After Installation
- Check Model Number: Confirm your mamaRoo is indeed Model 1037. This part is not compatible with other models.
- Verify Installation: Ensure the attachment point and spacer are correctly oriented and fully inserted. A tight fit is expected.
- Inspect for Damage: If the new part was damaged during installation or arrived damaged, it may not function correctly. Contact support for assistance.
8.2 Part Does Not Fit
- Double-Check Model: Reconfirm your mamaRoo model number.
- Examine Spacer Orientation: The spacer has a thick and thin side; try adjusting its orientation.
- Gentle Force: The fit can be snug. Apply gentle, even pressure during installation. Avoid excessive force that could cause breakage.
