    							At the start of this manual, you were informed that this book
    covers the operation of multiple models of sewing machines.
    The primary difference between the various models is the type
    and number of stitch patterns. In addition to stitch patterns
    there is also a difference in the number of dials used to modify
    the patterns.
    On all models stitch patterns are chosen by turning the stitch
    pattern selector dial. The pattern on an alphabet letter depicting
    the pattern will show in the stitch display window.
    As you study the chart on the right while examining your sewing
    machine you will be able to easily determine which model is
    your sewing machine.
    If you determine your sewing machine is either A or B model
    pay attention to the instructions on the next page for stitch width
    dial and stitch length dial.
    If you have model C then ignore the instructions for stitch width
    dial and only pay attention to stitch length dial.
    If you have model D then all your pattern lengths and widths
    are pre-set and you do not have length or width dials.

    							Function of stitch width dial
    Function of stitch length dial while zigzaging(for models A & B)
    The maximum zigzag stitch width for zigzag stitching is 5mm;
    however, the width can be reduced on any patterns. The width
    increases as you move zigzag dial from 0 - 5. For twin
    needle sewing, never set the width wider than 3 (1).
    The stitch width dial is also the control for the straight stitch
    infinite needle position. 0 position is full left, 5 is full right
    and between 2 and 3 is center needle position.
    (for models A, B & C)
    The density of zigzag stitches increase as the setting of stitch
    length dial approaches 0.
    Neat zigzag stitches are usually achieved at 2.5 or below (2).
    Closed up zigzag stitches are called satin stitches (2).
    For straight stitch sewing, generally speaking, the thicker the
    fabric, thread and needle, the longer the stitch should be.

    density varies according to the fabric. Always test sew a

    with the stitch pattern selector dial. Take care not to sew too
    many stitches in stages 2 and 4. Use seam ripper and cut
    buttonhole open from both ends towards the middle.
    - Slightly reduce upper thread tension produce better results.
    - Use a backing for fine or stretchy fabrics.
    - It is advisable to use heavy thread or cord for stretch or knit
    fabrics.
    - The zig-zag should sew over the heavy thread or cord.on the
    buttonhole foot aligns with starting marking on fabric. Lower
    the foot, so that the buttonhole center line marked on the
    fabric aligns with the center of the buttonhole foot.
