Operating the Clothing Sewing Machine - continued.
(1) To insert material into the machine perform the following:
(a) Lift the presser bar hand lifter (1) to raise the presser foot (2) which should now have about 3
inches of bobbin thread (3) and needle thread (4) under and behind it.
(b) Place the edge of the material under the presser foot (2) and the needle thread (4), at the
same time hand-turn the pulley wheel toward you until the needle is in the material at the
desired starting point.
(c) Place the end of the needle thread (3) toward the rear of the presser foot (2), and then lower
the presser foot on the needle and thread.
(2) Set motor switch to the ON position.
(3) To sew material perform the following:
While you are sewing hold the work flat, but do not push or pull on the material. Let the feed dog
carry the work evenly under the presser foot and needle. If the operator pulls on the fabric, the
needle bends, strikes the throat plate, and is either dulled or, more likely, broken. When the
needle is about to cross a seam or other unusually thick or uneven place in the work, disengage
the clutch, and hand-turn the machine over the rough place; otherwise, the needle may be
broken or thrown out of time.
(a) Hand-turn the machine hand wheel toward you and simultaneously
hold the needle and
bobbin threads until a few stitches are made. Press the foot treadle slowly to engage the
clutch with motor. Let the feed dog carry the material evenly under the presser foot and
(b) If the material is unusually thick, as a comforter for example, decrease the tension on the
presser foot by turning the tension assembly thumbscrew counterclockwise.
