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.

Note
• Slowly and evenly wind the thread around
the bobbin.
• For best results, wind the bobbin so the
thread is snug and not twisted.
CAUTION
• If thread extends beyond the top of the bobbin
too much, the thread may become tangled or
the needle may break.
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 through the
groove in the needle plate cover, otherwise
the lower threading cannot be done correctly.
