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 “Sewing attractive finishes”
(page 166).
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.
a Do not turn a phillips screw (+).
b Adjust with a screwdriver (small).

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.
