Features & Benefits
Automatic Thread Tension — Fast, Consistent Results
Select a stitch and the **Auto Tension Dial** sets thread tensions automatically for a balanced, neat seam. Great for busy sewists who want accuracy without trial‑and‑error tension tweaking.
2/3/4‑Thread Capability for Every Finish
- 4‑thread overlock: durable construction seams for everyday garments.
- 3‑thread overlock (narrow/wide): clean edge finishing with less bulk.
- 2‑thread rolled hem / narrow edge: quick, delicate hems on sheers and scarves.
- Flatlock: decorative ladder seams and sporty, low‑profile finishes.
High Productivity with Smooth Fabric Control
- Speed: sew up to 1,100–1,200 stitches per minute for rapid finishing.
- Differential feed: prevents wavy seams on knits and puckers on lightweight wovens; also enables controlled gathering.
- Extra presser‑foot height & large sewing space: easier handling of bulk, layers, and lofty textiles.
Easy Setup & Adjustability
- Color‑coded lay‑in threading paths: intuitive threading and rethreading.
- Adjustable cutting width & stitch length: tailor seam bite and finish to fabric; fine‑tune for decorative looks.
- Front cover safety interlock: machine won’t sew when the cover is open.
Ideal Projects & Fabrics
- Everyday garments, athleisure, swimwear, and baby/children’s clothing.
- Rolled hems on chiffon, organza, voile, and delicate decorative edges.
- Home décor: cushions, napkins, table linens, curtains, and soft accessories.
- Creative accents: flatlock ladders, wave edges (with appropriate settings), and contrast-thread finishes.

Frequently Asked Questions
Can it handle knits and lightweight fabrics without wavy seams?
Yes. Use the differential feed to prevent stretching on knits and to stop puckering on light wovens; you can also use it to create gathers.
Is threading difficult for beginners?
Threading is simplified with color‑coded, lay‑in paths and front covers that open wide, making access to loopers straightforward.
What hems and finishes can I make?
Standard 3‑ and 4‑thread overlock seams, narrow/wide overlock finishes, rolled hems, flatlock (ladder) seams, decorative open‑work edges, and more.
Does it include everything to start?
Yes—23 essential accessories are included (bobbins not required for sergers). Add specialty presser feet as your projects evolve.
