[. . . ] Now turn the handle over from you to work the machine, without its being threaded, until you are accustomed to guiding the material with the left hand. FIG. 3 6 27 & 28 To Ensure Perfect Action of the Machine The hand wheel must always turn over towards you. Do not work the machine with the presser foot lowered or with the shuttle and the needle threaded, except when sewing Both slides over the shuttle must be kept closed. 4) Raise the needle bar to its highest point and loosen the thumb screw. [. . . ] NOTE: Keep the inside of the shuttle and under the tension spring (see Fig. 10 12 27 & 28 To Prepare for Sewing With the left hand hold the end of the needle thread, leaving it slack from the hand to the needle. Turn the hand wheel over towards you for the needle to move down and up again to its highest. Pull the thread you are holding, and the under thread will be brought up with it through the hole in the throat plate, as shown in Fig. To Commence Sewing Place the material to be sewn beneath the presser foot, lower the latter, and commence to sew by turning the hand wheel over towards you. FIG. 11 To Remove the Work NOTE: Do not try to help the feeding of the work by pulling the material, as Raise the needle bar to its highest, lift the presser foot (7, Fig. 5), at the same time pressing the this may deflect the needle and tension release (10, Fig. left, and sever the threads by passing them over the thread cutter above the presser foot. Leave a few inches of thread under and at the back of the presser foot. 13 27 & 28 To Regulate the Tensions Correct Stitch. For ordinary stitching, the tension on the upper and under threads should be equal, so as to lock both threads in the centre of the work, as above. If either tension is stronger than the other, imperfect stitching will be the result, thus: Needle Thread Tension too strong. FIG. 12 Needle Thread Tension too weak. Lower the presser foot and turn the thumb nut in the direction illustrated by the arrow to increase the tension or in the opposite direction to lessen it. If the needle thread breaks, see that: The machine is properly threaded. The thread is not too coarse for the needle (see table on inside of back cover). Should the under thread break, loosen the under tension (see page 11), and see that the shuttle and under the tension spring are free from fluff. See that the needle is correctly set (see page 5), is not blunt, bent, or too fine for the thread. 5) is not broken, that the upper and under tensions are equal, that both shuttle and needle are properly threaded, that the thread is of good quality and of correct size for the needle (see table on inside of back cover). See that both tensions are equal. 18 27 & 28 INSTRUCTIONS FOR USING ATTACHMENTS WHICH MAY BE USED WITH SINGER* SEWING MACHINE No. Before applying any of these attachments raise the needle and remove the presses foot. After substitut ing the attachment turn the hand wheel slowly over towards you to make sure that the needle passes through the centre of the needle hole. Darning by sewing machine is infinitely neater, stronger, and more quickly done than by hand. Read how to do this in separate pamphlet, Form 1001 ad 33, which maybe obtained free from any SINGER SEWING CENTRE or Singer Salesman. 19 27 & 28 Bias Gauge The Bias Gauge will be found very useful (especially in the case of soft materials) when cutting bias steps from 7/16 inch to 1 3/8 inches in width. The edge to be bound must be allowed to pass freely through the scroll and should not be crowded in or against it. [. . . ] Then push the edges at the beginning of the seam into the mouth of the hemmer, as far as the needle, and lower the hemmer foot. While stitching, keep the material perfectly flat, using both hands, and see that the seam is in line with the mouth of the hemmer. For the second seam, the stitch should be lengthened slightly. 28 27 & 28 The Adjustable Hemmer With its slide closed, the attachment will make hems up to one inch wide. Loosen the screw at the front and move the slide until the pointer is against the desired width then tighten the screw. [. . . ]
