You should be able to fit a 4mm hex wrench (allen key) between the needle and the presser foot. If the 4mm wrench does not fit, follow the steps below:
- Move the Needle Case to Needle #1.
- In the Operating Software, click on Tools > Maintenance > Head Timing > and click the Bottom Center button.
- The following adjustment is very sensitive. Do Not push or bend the top portion of the Presser foot.
- Use two Needle Nose Pliers to grab the Presser foot in the locations shown below:
- Hold the top Plier in place so it doesn’t move.
- Twist the bottom Plier down and backwards slightly to create a 4mm gap.
- Use the 4mm wrench to confirm the gap is correct.
