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.

Memo
• If inserting thread tail through bobbin hole is
difficult, bobbin can be wound by holding
the tail and wrapping thread around inside
base. Then carefully trim thread tail so it
does not extend from the side of the
bobbin.
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 completely becoming tangled or
damage to the machine.
• Do not guide the bobbin thread completely
through the groove in the needle plate cover,
otherwise the lower threading cannot be done
correctly. Thread only as far as shown below.
