■ When tension is not applied to the bobbin
thread
If the bobbin thread in the trial stitching is too tight and
adjusting the bobbin case tension does not help (*As
described in “Adjusting the Tension of the Bobbin
Thread” on page 13), do not pass the thread through the
tension spring.
Hold the bobbin with your left hand so the thread
unwinds from the right side and hold the end of the
thread with your right hand.
k
Pull out about 8 cm (approx. 3 inches) of
bobbin thread.
l
Lightly hold the end of the upper thread while
turning the handwheel toward you
(counterclockwise) until the mark on the
handwheel aligns with the center top of
machine.
m
Gently pull the upper thread to bring the
bobbin thread up through the needle plate.
→ A loop of the bobbin thread comes out through the
hole in the needle plate.
n
Insert tweezers through bobbin thread loop
and pull bobbin thread above the needle
plate.
o
Align the upper thread and bobbin thread,
and then pull out about 10 cm (approx.
4 inches) of the threads and pass them under
the presser foot toward the rear of the
machine.
