WINDING THE BOBBIN
1. Push the bobbin winder switch
down to raise bobbin winder
2. Remove see-through bobbin
cover by sliding it toward the front
of machine.
Insure that the bobbin case is in
the proper position. The bobbin
case is held in place by a position
plate, which is designed to flex
slightly to allow the bobbin case to
move back and forth freely, about
1/16”.
The screw head should line up
with the seam in plastic casing of
machine and bobbin case should
move back and forth slightly
(about 1/16”) when hand wheel is
turned. If not, refer to page 17 for
repositioning instructions.

3. Remove empty bobbin from
bobbin case. The seam ripper
may make removal easier. Place
bobbin on the bobbin winder,
aligning the hole in bobbin with
the driving pin on bobbin winder.
You may have to turn the hand
wheel to help locate the driving
pin.
4. Slide spool of thread onto the
spool pin. NOTE: Make certain
that the thread retaining slit on
spool is near the bottom.
Otherwise, thread can become
caught in the slit and cause
problems during sewing.
