Fabric Compatibility
The serger is compatible with a wide range of fabrics, from light to heavy, including cotton, denim, knitting, hemp, chenille, canvas, modal, and mesh. The differential feeding system helps prevent puckering on light fabrics and stretching on elastic fabrics.

Stitch Length Adjustment
To adjust the stitch length (front and back density):
- Loosen the screw.
- Adjust the black stitch nut.
For more specific operations, please consult the operation video provided on the product's detail page or the comprehensive instruction manual included with your machine.
