Attention
Please review these important instructions regarding the bobbin case
The Operation Manual refers to the alternate bobbin case as
the
“alternate bobbin case (pink marking)”. However going
forward, the alternate bobbin case will be referred to as
“with no marking”. This machine comes equipped with the
alternate bobbin case (with no marking) for use in the same
manner as the
“alternate bobbin case (with pink marking)”.

Adjusting the Alternate Bobbin Case
(with no marking)
A bobbin case with a green marking has been installed in
this machine, with an alternate bobbin case (with no mark-
ing) provided as an accessory. 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 marking) 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 marking)
can be easily adjusted when bobbin tension changes are
required to accommodate different bobbin threads.
To adjust the bobbin tension for embroidery function, using
the alternate bobbin case (with no marking), turn the slot-
ted-head (-) screw with a (small) screwdriver.

If this occurs, turn the slotted-head screw (-) counter-
clockwise, being careful not to over-tighten 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 Phil-
lips (+) screw on the alternate bobbin
case as this may result in damage to the
bobbin case, rendering it unusable.
If the slotted-head 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.
