PREPARING FOR SEWING
(a) Pull sufficient thread through the needle and with the
left hand hold the end, leaving it slack from the hand to
the needle.
(b) Turn the balance wheel toward you until the needle
moves down Snd up again, thus catching the under thread.
(c) When the take-up lever is at its highest point, pull the
end of the needle thread you are holding and the under
thread will be brought up with it through the needle hole
in the needle plate.
(d) Lay both ends of thread under and to the back of the
presser foot, and having inserted the material to be stitch,
ed, lower the presser bar lifter and commence to sew by
turning the balance wheel toward you.
Do not try to help the feeding of the work by pulling the
material, as this may deflect the needle and cause it to break.
The machine feeds without any assistance.
Never operate the machine without material under the presser
foot.
