  • Page 12: Reverse Sewing

    To Regulate the Stitch Length Most sewing will be done with the maximum stitch length. How- ever, the length of the stitch can be adjusted as follows: (1) Loosen the thumb nut on the stitch length lever. (2) Raise the stitch length (feed regulator) lever until the desired stitch length is obtained.

    Adjusting Upper Thread Tension The correct stitch can usually be obtained by varying the upper thread tension. NOTE: TENSION ADJUSTMENT SHOULD BE MADE WITH THE PRESSER FOOT DOWN. To increase the tension, turn the tension dial clockwise (Fig. 32). To decrease the tension, turn the tension dial counter clockwise (Fig.

  • Page 16: Common Sewing Problems

    In order to adjust the machine properly, here are the fundamental operations of a lock stitch sewing machine. A shuttle hook rotates around the cage that holds the bobbin thread under the machine. The hook passes right next to the needle as it rises and catches the loop that is formed in the upper thread beside the needle as it comes up.
  • Page 17 2) Adjust the Foot Pressure Check to make sure the there is proper foot pressure. Closely–woven materials such as vinyl, and canvas can make it diffi cult for the needle to be withdrawn from the fabric. If the presser foot is lifting as the needle comes out of the fabric the effect is the same as if the needle were not going far enough into the cloth.

    fi g. 11 fi g. 12 Screwdriver insertion location Needle to adjust needle bar height hook point behind needle 4) To Check the Hook Distance If poor stitching still occurs after the needle bar height has been set properly, then the distance or the position of the hook must be checked.
  • Page 19 Another way to view the hook position in relation to the needle is to remove only the bob- bin case and shuttle hook retainer ring. With your left hand hold the hook in place and with the right hand rotate the hand wheel. You should be able to determine the distance between them by looking at the needle and hook from the bottom.
  • Page 20 Shuttle Race Rotation If it becomes necessary to change the hook distance you must fi rst make a mark on the hook shaft to reference where the proper rotation of the race must be. To provide a reference point, make a mark on the shaft just to the right of the shuttle race clamp (See fi...
  • Page 21 fi g. 15 Shuttle Center Lower Shaft Cast Iron Leg Clamp Left Collar Right Collar To adjust the hook to the right, loosen the two screws in the right collar. Move the collar to the left on its shaft. Move the shaft to the right. You will notice that the shaft, hook and shuttle will all move together.
  • Page 22 Moving the Hook Closer to the Needle To adjust the hook to the left is done by loosening the compressible clamp screw and moving the shaft to the left. The shaft, hook and shuttle all move together. Rotate the balance wheel so that the hook is at its highest point at the top, where is crosses the needle.
  • Page 23 needle is at bottom dead center. (See fi g. 16A) The hook rotation is critical, and the range of rotation is small, if set too far outside this range the machine may not sew at all or have skipped stitches. When the point can not catch the loop of thread formed by the needle, the hook point is set too close to the needle.
