Thread
Guide Body
Joint Screw
For proper winding, the spool or cone of thread and
the bobbin being filled by that thread should be
parallel with each other. If this is not the case,
unfasten the nuts on the bobbin winder and adjust
the body of the bobbin winder until they are parallel.
Wrench(2.5mm)
Winding Wheel
Rotation of the bobbin winder may become slower
with use. The joint screw of the winding wheel is set
so that it can be adjusted from 100 to 190 degrees.
Unscrew the joint screw of the winding wheel with
a wrench, move the winding wheel forward the
desired degree(s) and then refasten the joint screw
securely.
CAUTION
If the bobbin thread is wound off-center or uneven, as seen in these examples,
you may experience thread breaks, skipped stitches or birdnesting.
CAUTION
If the bobbin thread is wound too tight and the thread does not release smoothly,
you may experience thread breaks or short tails on the bobbin after trimming.
