    iPress .
    →The sewing screen is displayed.
    jPress  , and then adjust the tension of 
    the upper thread.
    For details on adjusting the tension of the upper 
    thread, refer to “Adjusting Thread Tension” on 
    page 233.
     CAUTION
     When sewing bobbin work, be sure to select an 
    embroidery pattern for bobbin work. If any other 
    type of pattern is selected, the machine may be 
    damaged.
    Note
     Embroidery sewing speed defaults to 350 spm when a bobbin work embroidery pattern 
    is selected. The Settings screen will not 
    allow speed to be adjusted.
    Memo
     When an embroidery pattern for bobbin work 
    is selected, the automatic thread cutting 
    function is turned off. Afterward, if a pattern 
    other than one for bobbin work is selected, 
    the automatic thread cutting function is 
    returned to the setting that was selected 
    before the embroidery pattern for bobbin 
    work was chosen.
    Note
     Since bobbin work is sewn from the wrong side of the fabric, the pattern shown in the 
    screen appears as a mirror image of the 
    final sewn embroidery. If necessary, flip the 
    image to preview it. In addition, when 
    sewing with the thread colors shown in the 
    sewing screen, select a bobbin thread that 
    matches what is shown in the screen.

    Memo
     With embroidery patterns for bobbin work, 
    the size and thread density cannot be 
    changed. In addition, the automatic thread 
    cutting function cannot be turned on.
    Memo
     We recommend a setting between 6 and 8 for the upper thread tension.

    Start Embroidering
    aHoop the fabric so the right side of the 
    fabric is facing down with the stabilizer 
    lying on the top. Use an embroidery frame 
    that fits the size of the pattern and then 
    attach the frame to the machine. These 
    patterns are embroidered from the wrong 
    side of the fabric so technically you are 
    working in “reverse” of normal 
    embroidering.

    eUsing the presser foot lever, raise the 
    presser foot.
    fTo bring the bobbin thread above the 
    fabric, rotate the handwheel 
    counterclockwise while holding the upper 
    thread. 
    gAs shown below, pull the upper thread to 
    pull the bobbin thread up through the 
    fabric.

     CAUTION
     Always use a stabilizer material for embroidery. 
    Otherwise, the needle may break and cause 
    injuries. Not using a stabilizer material may result 
    in a poor finish to your project.
    Memo
     If the bobbin thread cannot be pulled up, use an awl to create small hole to help pull bob-
    bin thread to surface.

    hPress   to unlock all keys and 
    buttons.
     
    iLower the presser foot.
    jWhile holding both the upper thread and 
    the bobbin thread, sew a section of the 
    pattern.
    kStop the machine, and then tie the upper 
    thread and the bobbin thread together to 
    secure the threads.
    lStart sewing again to finish the pattern.
    mRaise the needle and presser foot, remove 
    the embroidery frame, and then cut the 
    upper thread and the bobbin thread.
    When cutting the threads, be sure to leave an 
    adequate length of thread so they can be 
    properly secured.
    nUsing a hand sewing needle such as a 
    ribbon embroidering needle, pull the 
    bobbin thread to the top (wrong side) of the 
    fabric, and then tie the upper thread and 
    the bobbin thread together.
    oRemove the fabric from the embroidery 
    frame, and check the finished embroidery.
    pIf the desired results could not be achieved, 
    adjust the tension of the bobbin thread and 
    of the upper thread, and then try sewing the 
    pattern again.
    For more details, refer to “ADJUSTING THE THREAD 
    TENSION” on page 322.
    Memo
     If there is a gap between the start point and end point of the pattern, cut the threads, 
    remove the fabric from the machine, and 
    then use a ribbon embroidering needle to 
    hand sew stitches to connect the starting 
    and ending points.

    Memo
     Check bobbin after each bobbin work 
    embroidery pattern is sewn to make sure 
    there is adequate bobbin thread for the next 
    pattern. 
    						
    							ADJUSTING THE THREAD TENSION
    322
    ADJUSTING THE THREAD TENSION
    After sewing trial stitches and checking the sewing results, adjust the thread tensions if necessary. After adjusting the 
    tensions, be sure to sew trial stitches again in order to check the sewing results.
    ■Adjusting the upper thread tension
    We recommend a setting between 6 and 8 for the upper 
    thread tension.
    If utility stitches are being used, refer to “Setting the 
    Thread Tension” on page 79. If embroidery patterns are 
    being used, refer to “Adjusting Thread Tension” on 
    page 233.
    ■Adjusting the tension of the bobbin 
    thread
    If the desired stitching cannot be achieved after 
    adjusting the upper thread tension, adjust the tension of 
    the bobbin thread. The tension of the bobbin thread can 
    be adjusted by turning the slotted-head (–) screw on the 
    bobbin case (gray) for bobbin work.
    a Do not turn the phillips screw (+).
    b Adjust with a small screwdriver.
    To increase the tension of the bobbin thread, turn the 
    slotted-head (–) screw 30° to 45° clockwise.
    To decrease the tension of the bobbin thread, turn the 
    slotted-head (–) screw 30° to 45° counterclockwise.
    Note
     Turning the screw on the bobbin case (gray) 
    may push up the spring plate, as shown 
    below.
    If this occurs, gently press down the spring 
    plate with a screwdriver so it is lower than 
    the top surface of the bobbin case (gray), 
    and then insert the bobbin case into the 
    machine.
    a Spring plate
     CAUTION
     DO NOT adjust the position of the phillips (+) 
    screw on the bobbin case (gray) as this may result in 
    damage to the bobbin case, rendering it useless.
     If the slotted screw (-) is difficult to turn, do not use  force. Turning the screw too much or providing 
    force in either (rotational) direction may cause 
    damage to the bobbin case. Should damage occur, 
    the bobbin case may not maintain proper tension.
    Note
     If the bobbin thread tension is tight, the thread cannot be passed through the 
    tension spring when the bobbin is installed 
    in the bobbin case. (Refer to “When tension 
    is not applied to the bobbin thread” on 
    page 312.)

    TROUBLESHOOTING
    Several solutions for minor problems are described below. If the problem persists, contact your nearest authorized 
    Brother dealer.
    ■The thread was accidentally cut 
    automatically and the bobbin thread 
    is caught inside the machine
    aCut the thread near the fabric above the 
    needle plate, and then remove the fabric.
    a Thread
    bRemove the bobbin, and then hold it out 
    toward the left side of the machine.
    cLower the presser foot.
    dApply slight tension on bobbin thread by 
    holding thread out to the left side of presser 
    foot. Press the “Thread Cutter” button 
    again.
    ■The pattern is misaligned
    Refer to “ADJUSTING THE THREAD TENSION” and 
    increase the upper thread tension. If the pattern is 
    still misaligned, reduce the tension of the bobbin 
    thread.
    Example: Decorative Stitch
    a Correct tension
    b The upper thread tension is too loose, or the 
    bobbin thread tension is too tight.
    ■The bobbin thread catches on the 
    tension spring of the bobbin case
    Sew with no tension applied to the bobbin thread. 
    (Refer to “When tension is not applied to the bobbin 
    thread” on page 312.)
    Note
     If an embroidery pattern was sewn, remove 
    the embroidery frame.
     CAUTION
     Do not pull on the thread with excessive force, 
    otherwise the machine may be damaged.

    							DESIGNING A STITCH
    326
    DESIGNING A STITCH
    By using the MY CUSTOM STITCH function, you 
    can register stitches you have created yourself. 
    You can also sew designs combining MY 
    CUSTOM STITCH creations with built-in 
    characters (see page 170).
    aDraw the stitch design on the grid sheet 
    (part code SA507, GS3:X81277-151). 
    bDecide the spacing of the stitch.
    * By adjusting the spacing of a stitch, you can create various patterns with one stitch.
    cPlace points where the pattern intersects 
    with the grid, and connect all the points 
    with a line.
    dDetermine the x and y coordinates of each 
    of the marked points. 
    Memo
     Stitches that you create with MY CUSTOM STITCH can be a maximum of 7 mm 
    (approx. 9/32 inch) wide and 37 mm 
    (approx. 1-1/3 inches) long.
     Stitches can be designed more easily with  MY CUSTOM STITCH if you first draw the 
    stitch on the included grid sheet.
    Memo
     Simplify the design so that it can be sewn as a continuous line. For a more attractive 
    stitch, close the design by intersecting lines.
    If the design is to be repeated and linked, 
    the start point and end point of the design 
    should be at the same height.
    Memo
     This will determine the stitch design that will be sewn.
