5.4 Needle Installation
Ensure the machine is off. Loosen the needle clamp screw, insert the new needle with the flat side facing the back, and tighten the screw securely. Always use the correct type and size of needle for your fabric.
6. Operating Instructions
6.1 Basic Stitching
Turn on the machine. Place your fabric under the presser foot. Lower the presser foot. Gently press the foot pedal to start sewing. Guide the fabric smoothly, allowing the machine to feed it. The machine's high speed (1100 rpm) allows for rapid completion of projects.

6.2 Adjusting Thread Tension
The machine features individual tension dials for each thread. Adjust these dials according to your fabric type and desired stitch. Incorrect tension can lead to loose or puckered seams. Perform test stitches on a scrap piece of your fabric to fine-tune tension settings.
6.3 Using Differential Feed
The differential feed lever allows you to adjust the feeding ratio of the front and rear feed dogs. Increase the ratio to stretch fabric (useful for knits) or decrease it to gather fabric. This prevents wavy seams on stretchy materials and puckering on fine fabrics.
6.4 Roll Hemming
To create a rolled hem, adjust the stitch finger and tension settings as described in the full manual. This function allows for neat, narrow hems on lightweight fabrics.
6.5 Utilizing the Cutting System
The integrated cutting system trims the fabric edge just before stitching, creating a clean, professional finish. Ensure the cutting blade is sharp and properly engaged for optimal results.
