3. Beroperasi
3.1 Jahitan Asas
- Pilih corak jahitan yang anda inginkan menggunakan dail pemilih jahitan.
- Laraskan panjang dan lebar jahitan mengikut keperluan untuk fabrik dan projek anda.
- Place fabric under the presser foot, lower the presser foot, and begin sewing by gently pressing the foot controller.
- Use the reverse lever for backstitching at the beginning and end of seams.
3.2 Pelarasan Ketegangan
Correct thread tension is crucial for balanced stitches. Adjust the upper thread tension dial according to your fabric and thread type. A balanced stitch will show equal amounts of upper and bobbin thread on both sides of the fabric.
3.3 Fungsi Sulaman
For embroidery, attach the embroidery unit (if applicable) and follow the specific instructions for pattern selection and hoop placement. Ensure the correct needle and stabilizer are used for your embroidery project.
3.4 Serging Functions
When using the serging capabilities, ensure the appropriate needles and threads are installed. Adjust differential feed and cutting width as required for neat, professional edges on various fabrics.
4. Penyelenggaraan

- Regularly clean lint and dust from the bobbin case, feed dogs, and needle plate area using a small brush.
- Disconnect the machine from power before cleaning.
4.2 Pelinciran
Refer to the lubrication points indicated in the original manual. Apply a small drop of high-quality sewing machine oil to these points periodically, especially after extended use.

Replace needles frequently (approximately every 8-10 hours of sewing) or when they become bent, dull, or damaged. Using a fresh, sharp needle prevents skipped stitches and fabric damage.
4.4 Penyimpanan
When not in use, cover the machine with a dust cover to protect it from dust and debris. Store in a dry, temperate environment.
