2. Pass thread through a hole in the spool pin (F) (most
direct route to bobbin tensioner).
For home sewing, refer to “NOTE” on p.15.
3. Wrap thread around bobbin tensioner (G).
4. Run under and up through a hole in top of bobbin
(H). Place bobbin on post and push to the right. Hold
onto thread tail briefly and power machine with the
clutch disengaged to wind bobbin. Stop after several
rotations and cut the thread tail off flush with the
bobbin side.
5. Continue winding until the bobbin is full. Then remove
the bobbin from the winder post by pushing the post
to the left and pulling the bobbin off. Cut the thread.

CAUTION: Do not overfill bobbin and force into

Engage the Clutch
To continue sewing, push the Posi-Pin (A) through one
of the holes in the balance wheel (I) (any will work).
While maintaining light pressure on the Posi-Pin, rotate
the balance wheel (J) until the Posi-Pin locks into one
of the holes in the bushing that the balance wheel rides
on. Push the Posi-Pin all the way in until the shoulder is
flush against the balance wheel. Rotating the balance
wheel will now cause the machine to function.
