2. Operating Instructions
2.1 Threading the Machine
Proper threading is crucial for optimal stitch quality. Follow the numbered guides on the machine for correct upper thread path. The thread take-up lever (located inside the machine body) pulls the thread up during sewing.
2.2 Winding the Bobbin
Place a SINGER Class 15 Transparent bobbin onto the bobbin winder spindle. Follow the winding path indicated on the machine. The bobbin stopper will automatically disengage the winder when the bobbin is full.
2.3 Inserting the Bobbin
Open the needle plate cover. Insert the wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction. Close the cover securely.
2.4 Controls and Adjustments
- Thread Tension Dial: Adjusts the tension of the upper thread. Factory set to 4, adjust as needed for different fabrics and threads. Turning right tightens, turning left loosens.
- Presser Foot Pressure Adjustment: This knob adjusts how hard the presser foot pushes on the fabric. It is factory preset and generally does not require adjustment.
- Reverse Sewing Lever: Hold this lever down to sew in reverse, useful for securing stitches at the beginning and end of a seam.
- Needle Position Dial: Allows you to move the needle position left or right, useful for precise stitching or specific techniques like zipper insertion.
- Stitch Width Dial: Controls the width of zigzag and decorative stitches.
- Stitch Length Dial: Controls the length of stitches.
2.5 Stitch Selection
The machine offers 215 stitch applications, including basic, stretch, and decorative stitches, and 6 one-step buttonhole styles. Refer to the stitch chart on the machine for available options.
2.6 Sewing
Place your fabric under the presser foot and lower the presser foot lever. Begin sewing by gently pressing the foot pedal. Use the Needle Up/Down feature for convenience when pivoting fabric.
3. Maintenance
3.1 Cleaning the Needle Plate Area
Regularly clean the area under the needle plate to remove lint and thread buildup, which can affect stitch quality. Unscrew the needle plate and use the included brush to clear any debris.
