Winding/Installing the Bobbin
Note
• When using the spool as shown below, use the
thread spool insert (mini king thread spool).
Make sure that the thread spool insert is firmly
inserted. After installing it, pull out some thread,
and check that the thread unwinds without getting
caught.
• When using thread that winds off quickly, such as
transparent nylon thread or metallic thread, place
the spool net over the spool before placing the
spool of thread onto the spool pin.
If the spool net is too long, fold it to fit the size of
the spool.
e
While holding the thread near the spool, pass the
thread through the thread guide cover.
And then, pass the thread under the thread guide plate,
and pull it to the right.

Pass the thread under the hook on the bobbin winding
thread guide, and then wind it counterclockwise under
the pretension disk.

Note
• Make sure that the thread is passed under the
pretension disk.
Wind the thread clockwise around the bobbin 5 or 6
times, pass the thread through the guide slit in the
bobbin winder seat, and then pull the thread to cut it.

(with built-in cutter)
Note
• Be sure to wind the thread clockwise around the
bobbin, otherwise the thread will become wrapped
around the bobbin winder shaft.
CAUTION
• Be sure to cut the thread as described. If the
bobbin is wound without cutting the thread
using the cutter built into the guide slit in the
bobbin winder seat, the thread may become
tangled in the bobbin or the needle may break
and cause injury when the bobbin thread starts
to run out.
Slide the sewing speed controller to adjust the bobbin
winding speed. Slide the controller to the right to
increase the speed; slide it to the left to reduce the
speed.
Memo
• We recommend winding stretch thread, such as
transparent nylon thread, at a low speed since the
thread may stretch.
