ADJUSTING THE ALTERNATE BOBBIN CASE (WITH NO COLOR ON THE SCREW)

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. See
"Sewing Attractive Finishes" on page 141.
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.

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.
