PREPARING FOR BOBBIN WORK
j
Install the bobbin wound with thread.
Whether or not tension should be applied to the
bobbin thread depends on the type of thread being
used.
■ When tension is applied to the
bobbin thread
Insert bobbin into bobbin case so the thread
unwinds from the left side.
Then correctly pass the thread through the tension
spring as shown below.

CAUTION
• When winding the bobbin, make sure the
thread is not frayed. Embroidering with frayed
thread may result in the thread catching on
the tension spring of the bobbin case, the
thread completely 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.

■ When tension is not applied to the
bobbin thread
If the bobbin thread in the trial pattern 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.
