4. Setup and Installation
Follow these steps to properly install the double toe walking foot on your compatible sewing machine.
- Power Off Machine: Ensure your sewing machine is turned off and unplugged from the power source for safety.
- Remove Existing Foot: Loosen the screw that holds the current presser foot in place and carefully remove it.
- Attach Outside Foot: Position the outside foot (#46970) onto the presser bar. Align the screw hole on the foot with the screw hole on the presser bar.
- Secure Outside Foot: Insert the screw and tighten it securely, but do not overtighten.
- Insert Inside Foot: Slide the inside foot (#40474-4) into the designated slot within the outside foot. Ensure it moves freely.
- Check Alignment: Manually lower the needle to ensure it passes cleanly through the needle hole of both the inside and outside feet without obstruction. Adjust the foot position slightly if necessary before fully tightening.
- Test Functionality: With the machine still off, manually turn the handwheel to observe the walking motion of the foot. Both feet should move in sync to feed the fabric.

5. Operating Instructions
The double toe walking foot is designed to provide superior fabric feeding, especially for thick, slippery, or multi-layered materials. Here are general guidelines for its use:
- Material Handling: Place your fabric layers evenly under the foot. The walking action will help grip and move all layers simultaneously.
- Stitch Length: Experiment with stitch length. For thicker materials, a slightly longer stitch length may be beneficial.
- Needle Selection: Use an appropriate needle size and type for your fabric. A heavy-duty needle is recommended for materials like leather or canvas.
- Thread Tension: Adjust your machine's thread tension as needed to achieve balanced stitches. The walking foot itself does not directly affect tension, but material thickness can.
- Speed: For optimal results, especially with challenging materials, sew at a moderate and consistent speed.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your walking foot.
- Cleaning: Periodically remove lint and dust from the foot, especially around the needle hole and feeding teeth, using a small brush or compressed air.
- Inspection: Regularly inspect the foot for any signs of wear, damage, or deformation. Ensure both the inside and outside feet move smoothly.
- Storage: When not in use, store the walking foot in a clean, dry place to prevent rust or damage.
7. Troubleshooting
If you encounter issues while using the walking foot, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Needle rubs against the foot. | Foot not properly aligned or secured. | Loosen the screw, adjust the foot slightly to ensure the needle passes freely, then re-tighten. Ensure the correct foot size for your machine. |
| Uneven feeding or puckering. | Incorrect tension, wrong stitch length, or foot not moving freely. | Adjust thread tension. Increase stitch length for thicker materials. Clean any debris from the foot mechanism. |
| Foot feels loose or wobbly. | Mounting screw is loose. | Ensure the mounting screw is tightened securely. |
