Drawing Up The Lower Thread
After threading machine and placing fi lled bobbin in
case into shuttle:
1 Hold the end of the
upper thread loosely
with your left hand,
so that thread remains
slack.
2 Turn fl y wheel slowly
toward you until
needle goes down and
comes up again to its
highest position. In
so doing, the upper
thread (needle thread)
will catch the lower
thread (bobbin thread).
3 Then pull up needle thread, and at the same time
the lower thread will be pulled up through stitch
hole in needle plate.
4 Both ends of thread must be drawn under and to
the rear of presser foot, about 6 inches.
Always turn the top of the balance wheel
of the machine toward you to reduce the
possibility of a thread jam in the lower
mechanism. Never operate the machine
without material under the presser foot.
Doing so will most likely "lock up" your
machine and it will be inoperable until the
thread jam is cleared.
