The machine includes a free arm for sewing cuffs and hems and provides adjustable stitch length and width for a range of sewing tasks.

Advantages

Select the desired stitch pattern and set stitch length and width using the dials. Adjust presser foot pressure for fabric thickness and raise the extra-high presser foot lifter to place multiple layers under the foot. Use the free arm to access cuffs, collars and hems. For buttonholes, choose the 1-step buttonhole setting and follow the machine’s guide to create a buttonhole automatically.

Recommendations

Use appropriate needles and threads for heavyweight materials and test stitch settings on a fabric scrap before sewing the final piece. Regularly clean lint from the stainless steel bed plate and bobbin area and follow the manufacturer’s maintenance schedule to ensure long-lasting performance.
