Setup and Installation

Before installing the presser foot, ensure your sewing machine is turned off and unplugged for safety. This presser foot is compatible with Yamato VC3611 and VC3711-D Interlock Coverstitch Sewing Machines that require a 6.4mm needle distance.

1. Remove Existing Presser Foot: Carefully lift the presser foot lever. Loosen the screw that secures the current presser foot to the presser bar and remove it.
2. Align New Presser Foot: Position the Blooy 3117126 Presser Foot under the presser bar, aligning the hole on the presser foot with the screw hole on the presser bar.
3. Secure Presser Foot: Insert the screw through the presser foot and into the presser bar. Tighten the screw firmly but do not overtighten, as this may damage the components.
4. Verify Installation: Gently lower the presser foot lever to ensure the foot is securely attached and moves freely up and down with the lever.

Troubleshooting

If you encounter issues while using the Blooy 3117126 Presser Foot, consider the following common solutions:

• Uneven Stitching: Ensure the presser foot is securely attached and not loose. Check for any lint buildup under the foot or around the feed dogs. Verify that the fabric is being fed evenly.
• Skipped Stitches: This is often related to needle issues (bent, dull, or incorrect type) or tension settings, rather than the presser foot itself. However, ensure the presser foot is not obstructing needle movement.
• Fabric Not Feeding: Check if the presser foot is lowered correctly. Ensure the feed dogs are engaged and clean.
• Presser Foot Damage: If the presser foot appears bent or damaged, replace it immediately to prevent further issues with your sewing machine.
