Adjusting the Alternate Bobbin Case (with No Color on the Adjusting Screw)
To adjust the bobbin tension for embroidery function, using the alternate bobbin case (with no color on the screw), turn the slotted screw (-) with a (small) screwdriver.
- The bobbin case that is used differs depending on the embroidery bobbin thread that is used. Only the alternate bobbin case allows the bobbin thread tension to be adjusted. For details, refer to Embroidering Attractive Finishes.
- Do not turn the phillips screw (+).
- Adjust with a screwdriver (small).IMPORTANT
- Do not adjust the position of the phillips (+) screw on the alternate bobbin case as this may result in damage to the bobbin case, rendering it unusable.
- If the slotted screw (-) is difficult to turn, do not use force. Turning the screw too much or providing force in either (rotational) direction may cause damage to the bobbin case. Should damage occur, the bobbin case may not maintain proper tension.
- When adjusting the alternate bobbin case, be sure to remove the bobbin from the alternate bobbin case.

If this occurs, turn the slotted screw (-) clockwise, being careful not to over-tighten the screw, approximately 30-45 degrees to increase bobbin tension.
Bobbin Thread is Too Tight
Upper thread on the right side of fabric seems to be lifting/looping and bobbin thread is not seen on the wrong side of fabric.

If this occurs, turn the slotted screw (-) counterclockwise, being careful not to over-loosen the screw, approximately 30-45 degrees to decrease bobbin tension.
