How to use

Use the free arm by removing or positioning the accessory plate to handle cuffs and sleeves.

Use the one-step buttonhole function when finishing garments by marking the button position and following the machine's buttonhole sequence.

Recommendations

For best results with heavy or multiple-layer fabrics, use an appropriate needle (denim or heavy-duty), a polyester or heavy-weight thread, and reduce sewing speed when approaching seams with many layers. Regularly clean lint from the bobbin area and follow the manufacturer's maintenance schedule to preserve machine performance.
