BEGINNING TO SEW
After threading the threads correctly, you can
begin your trial sew.
1. Raise the presser foot and place the fabric
sample underneath. Lower the presser foot
and start sewing. Do not raise the presser
foot while the overlock is in operation, as the
stitching will be uneven.
2. Before pressing the foot pedal, with your right
hand, turn the handwheel counter clockwise
while holding the end of the thread with your
left hand.
