2.1 Disimballaggio e posizionamento
- Estrarre con cautela la macchina dall'imballaggio. Conservare tutto il materiale di imballaggio per eventuali trasporti o rimessaggio futuri.
- Place the machine on a stable, level surface with adequate lighting. Ensure there is sufficient space around the machine for fabric handling.
- Connect the foot controller and power cord to the machine and then to a suitable electrical outlet.
2.2 Installazione dell'ago
- Ruotare il volantino verso di sé per sollevare la barra dell'ago nella posizione più alta.
- Allentare l'ago clamp vite.
- Inserire un nuovo ago con il lato piatto rivolto verso il retro della macchina, spingendolo verso l'alto il più possibile.
- Stringere l'ago clamp avvitare saldamente.
2.3 Avvolgimento della bobina
To wind the bobbin:
- Posizionare un rocchetto di filo sul portarocchetto.
- Far passare il filo attraverso il disco di tensione per l'avvolgimento della bobina.
- Posizionare la bobina vuota sul perno dell'avvolgitore.
- Start the machine; the bobbin will wind automatically. Stop when full.
2.4 Infilatura della macchina
Follow the numbered threading path indicated on the machine, ensuring the thread passes through all guides and the take-up lever. Thread the needle from front to back.
3. Operativo
3.1 Cucito di base
- Select your desired stitch pattern using the stitch selector dial.
- Adjust stitch length and width as needed for your fabric and project.
- 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 Regolazione della tensione
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 Funzioni di ricamo
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. Manutenzione
4.1 Pulizia
- 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 Lubrificazione
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.
4.3 Sostituzione dell'ago
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 Conservazione
When not in use, cover the machine with a dust cover to protect it from dust and debris. Store in a dry, temperate environment.
