For details on starting to sew, refer to “Starting to sew” (page 23). Stitch width knob Stitch width knob The width of the zigzag stitch is regulated by operating the stitch width knob. The numbers above the knob represent the stitch width in millimeters (mm). The larger numbers set a wider stitch width. When the knob is set at 0, a straight stitch is sewn. 2aStitch width knob NoteaStitch length knob bShorter cLonger Needle position selector By shifting this lever to L (left), M (middle) or R (right), you can sew straight and zigzag stitches on the baseline. When you sew close to the edge of the fabric, select L or R so the fabric is fed more easily. This selector should be set at M (middle) for almost all stitches, but set it to other positions for the following applications. 1. Buttonhole sewing (see “Buttonhole sewing” on . Do not move the knob while the needle is in the fabric. . When using the twin needle, the knob should always be set below 3. Stitch length knob The stitch length is regulated by turning this knob. The numbers above the knob represent the stitch length in millimeters (mm). The larger numbers set a longer stitch length. When the knob is set to 0, the fabric is not fed. This setting is used for sewing on a button. The F area is used for making a Satin Stitch (a close zigzag stitch), which can be used in making buttonholes and decorative stitches. The position needed for making the Satin Stitch may need to be adjusted according to the fabric and thread being used. To determine the correct knob position, first test the length settings on a fabric scrap. page 30.) 2. Button sewing (see “Button sewing” on page 31.) 3. Satin stitches (see “Satin stitches” on page 36.) Note . Do not move the selector while the needle is in the fabric. . Always set the selector to M when using the twin needle. 22 SEWING BASICS SEWING BASICS Starting to sew Turn on the sewing machine. a b Raise the needle to its highest position by turning the handwheel toward you (counterclockwise). Raise the presser foot lever. c a Presser foot lever d Place the fabric under the presser foot, pass the thread under the presser foot, and then pull out about 5 cm (2 inches) of thread toward the rear of the machine. a 5 cm (2 inches) While holding the end of the thread and the e fabric with your left hand, turn the handwheel toward you (counterclockwise) with your right hand to lower the needle to the starting point of the stitching. f Lower the presser foot lever. a Presser foot lever Slowly press down on the foot controller. g • The machine starts sewing. hTake your foot off the foot controller. • The machine stops sewing. i Raise the needle to its highest position by turning the handwheel toward you (counterclockwise). j Raise the presser foot lever. k Pull the fabric to the left side of the machine, and then pass the threads through the thread cutter on the back of the presser foot bar to cut them. a Thread cutter Sewing in reverse Reverse sewing is used to lock the threads at the end of the seam or wherever reinforcement is needed. Press and hold down the reverse sewing lever a while sewing. b To sew forward, release the reverse sewing lever. Thread tension Thread tension The thread tension will affect the quality of your stitches. You may need to adjust it when you change fabric or thread. Memo . Before beginning to change tension adjustments make sure the upper thread and bobbin are inserted correctly. . We recommend you do a test sample on a scrap of fabric before you start to sew. ¦ Correct tension Correct tension is important as too much or too little tension will weaken your seams or cause puckers on your fabric. 1 3 4 a Wrong side b Surface c Upper thread d Lower thread 2 ¦ Upper tension is too tight Loops appear on the surface of the fabric. Note . If the bobbin thread was incorrectly inserted, the upper thread may be too tight. In this case, refer to “Lower threading” (page 11) and reinsert the bobbin. 1 a Wrong side b Surface c Upper thread d Lower thread e Loops appear on surface of fabric 2 Solution Reduce the tension by turning the upper tension- control dial to a lower number. 35 4 ¦ Upper tension is too loose Loops appear on the wrong side of the fabric. Note . If the upper thread was incorrectly threaded, the upper thread may be too loose. In this case, refer to “Upper threading” (page 13) and rethread. 5 a Wrong side b Surface c Upper thread 2 d Lower thread e Loops appear on wrong side of fabric Solution Increase the tension by turning the upper tension- control dial to a higher number. ¦ Bobbin tension is too loose Loops may appear on the surface of the fabric when sewing thin fabric with thin thread. 1 a Wrong side b Surface c Upper thread 2 d Lower thread e Loops appear on surface of fabric Solution Reduce the tension by turning the upper tension- control dial to a lower number. If the problem persists, increase the tension in the bobbin by turning the screw clockwise with a screwdriver. Be sure not to tu...
