Setting the zigzag width
Set the zigzag width after selecting the pattern number. The zigzag width is defined as the distance between the
leftmost needle drop point and the rightmost needle drop point. If the zigzag width is increased or reduced, the
width of the sewing pattern is also increased or reduced by the same proportion.
The zigzag width will be automatically set to [0.0 ] only when straight stitches have been selected as the
sewing pattern.

• The zigzag width cannot be changed if the setting value is not selected and the indicator is not illuminated,
even when the zigzag width is being displayed in the setting screen. When changing the zigzag width, press
so that the setting value illuminates.
• If the needle bar is at the needle up stop position, the needle bar will move to the sewing start position when
the zigzag width is changed.
If the needle bar is not at the needle up stop position, the needle bar will move to the sewing start position
after it next moves to the needle up stop position.
Sewing speed limits
The sewing speed is limited by the amount of zigzag movement. Accordingly, in the following sewing patterns,
the actual sewing speed will be different from the swing speed which is set because of the zigzag width setting,
adn the speed will be automatically controlled as follows.
For straight stitches and 3-step zigzag stitches, the sewing speed is not limited by the zigzag width setting.
