2-12. OPERATING PROCEDURES FOR DARNING SEWING MACHINE - continued.
h. Operating the Darning Sewing Machine. After the machine has been prepared for operation, operate
as follows using excess cloth. Make all thread and presser foot adjustments before starting repairs.
CAUTION
Always rotate the machine hand wheel towards you. Turning the hand wheel away
from you will break or bend needles or damage bobbin case or rotating sewing
hook.
NOTE
Before making clothing repairs, make sure of the adjustments by using a piece of
scrap cloth.
(1) Turn the switch on under the table.
(2) To insert material into the machine perform the following:
(a) Lift the presser bar hand lifter to raise the presser foot which now should have about five
inches of bobbin and needle threads under and behind it.
(b) Place the edge of the material under the presser foot , having the unworn part of the work
near the hole under the needle. Hold the needle thread until the first two stitches are
completed, then commence the darning by making a line of stitches across the hole a little
longer than the width of the hole. Continue making parallel lines of stitches across the hole,
moving the work backward and forward and at the same time gradually moving the work
sidewise until the hole is covered with lines of stitches running across the hole. Then
commence as before and move the work lengthwise of the hole until the stitches across the
hole are completely covered and the darn is finished.
(3) To remove material from the machine proceed as follows:
(a) Release the foot treadle to stop the machine.
(b) Hand-turn the hand wheel toward you until the needle bar is at its highest point, and raise the
presser foot.
(c) Draw the material straight behind the presser foot, and break or cut the needle and bobbin
threads so that about four inches will remain under and behind the presser foot.
