■ 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, 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.
CAUTION
• When winding the bobbin, make sure the thread is
not frayed. Sewing with frayed thread may result in
the thread catching on the tension spring of the
bobbin case, the thread becoming tangled or
damage to the machine.
• Do not guide the bobbin thread through the groove
in the needle plate cover, otherwise the lower
threading cannot be done correctly.
