							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.
