Adjusting the Alternate Bobbin Case (with
No Color on the Screw)
When using the embroidery bobbin thread provided,
please be sure to choose the green marked bobbin case
when performing utility stitch sewing and embroidery
functions. When in the embroidery function mode, the
alternate bobbin case (with no color on the screw)
should be selected when substitute embroidery bobbin
threads (other than what is accompanied with your
machine) are being used. The alternate bobbin case
(with no color on the screw) can be easily adjusted
when bobbin tension changes are required to
accommodate different bobbin threads. Refer to
“Embroidering Attractive Finishes” on page 134.
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.
1 Do not turn a phillips screw (+).
2 Adjust with a screwdriver (small).
■ Correct Tension
Upper thread slightly appears on the wrong side of fabric.
■ Bobbin Thread Is Too Loose
Bobbin thread appears slightly on the right side of fabric.
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.

CAUTION
• When adjusting the alternate bobbin case, be
sure to remove the bobbin from the alternate
bobbin case.
• 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.
