4. Run under and up through a hole in top of bobbin (H).
Place bobbin on post and push to the right. Hold onto

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.
