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.
