It will not allow me to press the in out button

The in/out button on the SunStar SWF/B Series could be unresponsive due to the presser foot not properly pressing the fabric when the needle exits. This causes the fabric to lift with the needle, creating a gap and leading to issues like thread breaks or skipped stitches, which may affect button responsiveness. Also, incorrect manual color change (not performed at the upper shaft angle of 100°) or improper adjustment of the half-turn film or sensor could contribute to the issue.

Thread Guide Disk (Pass through the middle of shaft) Wrap the thread around thread sensing roller one time. Thread Sensing Roller One turn Wrap the thread 1.5 times around the main tensioner in the V- groove between the rotary tension disks.

  • Page 35: Tension Control On Upper Thread

    TENSION CONTROL ON UPPER THREAD Proper tension is an important factor in producing quality embroidery. If the upper tension is too loose, looping and thread breaks may occur. If the tension is too tight, thread and needle breaks may occur as well as puckering.

  • Page 36: Take-Up Spring

    TAKE-UP SPRING The play between the pull of the upper thread by the Thread tension take-up lever and the pull of the thread by the hook adjusting stud creates tension on the upper thread. If the tension of the take-up spring is too tight, looping and loose stitches may result.

  • Page 37: Bobbin Threading And Tension Adjustment

  • Page 40: The Needle, The Hook And The Stitches

    CHAPTER THE NEEDLE, THE HOOK AND THE STITCHES STITCH FORMATION Understanding how a stitch is formed will help you understand hook timing and teach you to recognize quality embroidery. It will also help you better understand the importance of tension and the roles the different parts of the machine play in creating that tension and stitch.

  • Page 41: The Needle And Hook

    THE NEEDLE AND HOOK THE NEEDLE The needle is a slender piece of steel with an opening for thread called the eye and a point for piercing fabric so the thread can pass thought the Needle Groove fabric on the way to the bobbin housing. The needle and thread not only need to pierce the substrate, but Needle Eye also form the loop that helps create the stitch in the...
  • Page 42 Machine embroidery needles come in sharp points for piercing heavy, tightly woven fabric and ball points, which glide between the fibers of the knits. The size of yarn being pushed aside with the ball point determines the size of the needle. Light ball points (SES) are good for polo shirts, medium points (SUK) are good for fleece.

  • Page 43: Changing The Needle

    CHANGING THE NEEDLE Make sure that the needle is clear of the needle plate before attempting to change it. If the needle is not clear of the needle plate, use the hand wheel to raise the needle. Needle Needle Plate Hand Wheel STOP THE MACHINE BEFORE TURNING THE HAND WHEEL MANUALLY.

  • Page 44: Relationship Between Needle And Hook

    RELATIONSHIP BETWEEN NEEDLE AND HOOK The relationship between the needle and the hook is called timing. Timing between the needle and the hook is correct when the main shaft is 200 degrees. It is a good idea to use a Size 11 needle when adjusting the timing. Although needle size increases toward the front –...
  • Page 45 Hook Point Upper Point of Hook Point Hook Circumference Top Edge of Needle Eye Top Edge of Needle Eye Needle Tip Lowest Point of Needle Stroke The eye of the needle should be just below the point of the hook(b,c). The eye should look like a teardrop hanging from the point of the hook.
  • Page 46 The size of the eye of the needle-and the size of the needle groove varies-between different sizes of needles. Needle Groove The front groove of the needle cradles the thread and protects it from the heat of sewing friction Needle Eye (which can result in thread breaks.).

  • Page 47: Relationship Between Take-Up Lever And Hook

    RELATIONSHIP BETWEEN TAKE-UP LEVER AND HOOK The following pictures show the location of hook when the take-up lever starts to move up from the lower dead stop (main shaft rotation angle: 295°). When the hook timing falls in the A range (see In case of fast hook timing illustration below) the loop will be too small.

  • Page 48: Thread-Break Detecting Unit

    THREAD –BREAK DETECTING UNIT The thread-break detecting unit contains rollers which sense the smooth rotation of the thread which determines if there has been a break in the upper or lower thread. Any dust, thread remnants, etc. will interfere with the roller’s rotation and prevent detection of broken thread. Therefore, It is important to always keep the rollers and bush bearings clean and free of dust and dirt.

    CHAPTER BACKING Backings fall into three categories: tearaway, cutaway and specialty. Tearaway is a logical choice for many jobs and does not require scissors for removal-a safety feature for beginning embroiderers. Tearaways range in weight from one to three ounces per yard. A good tearaway is stable enough to stand up to multiple needle penetrations as well as tear well both directions.Tearaways that can be torn in only one direction can result in distortion of the embroidered design and unsightly remnants of the backing, which then must be cut away.

  • Page 158: Hooping And Tensions

    CHAPTER HOOPING AND TENSIONS The tension of the fabric in your hoop is just as important as the tension on the threads of your machine. Many a stitching problem can be traced to poor hooping. Proper hooping is one of the most important factors in producing quality stitching.
  • Page 159 Before you being, check for damage to the bobbin, its case and the cone or spool of thread you are using for stitching. Make sure that your machine is threaded correctly before you begin to check the tensions. Your upper thread should run through the pretensioners ( sub-controllers) and the main tensioner as well as the take-up lever and all the eyes and guides on the way to the needle.
