6. Operating Instructions

6.1 Stitch Length and Width Adjustment

Adjust the stitch length and width using the dedicated dials on the machine. Experiment with different settings on scrap fabric to achieve the desired stitch appearance for your project.

Figure 6.1: Dial for adjusting stitch length. A smaller number results in shorter stitches, while a larger number creates longer stitches.

Figure 6.2: Control for adjusting stitch width, allowing for wider or narrower seams.

6.2 Differential Feed

The adjustable differential feed allows you to control the feeding of fabric, preventing stretching or puckering on various fabric types. Adjust the dial to match your fabric's needs.

• Fabric Puckering/Stretching: Adjust the differential feed setting according to your fabric type.
• Uneven Stitches: Re-thread the machine completely, ensuring all threads are seated correctly in their tension discs and guides.
