Adjusting the Bobbin Case (with No Color on the Screw)
The bobbin case (with no color on the screw) can be easily adjusted when bobbin tension changes are required to accommodate different bobbin threads.
Embroidering Attractive Finishes
To adjust the bobbin tension for embroidery function, using the bobbin case (with no color on the screw), turn the slotted screw (-) with a (small) screwdriver.
- Do not turn a phillips screw (+).
- Adjust with a screwdriver (small).
Correct Tension
Upper thread slightly appears on the wrong side of fabric.
- Right side
- Wrong side
Bobbin Thread Is Too Loose
Bobbin thread appears slightly on the right side of fabric.
- Right side
- Wrong side
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.
- Right side
- Wrong side
If this occurs, turn the slotted screw (-) counterclockwise, being careful not to over-loosen the screw, approximately 30-45 degrees to decrease bobbin tension.
- DO NOT adjust the position of the phillips (+) screw on the 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 bobbin case, be sure to remove the bobbin from the bobbin case.
