Inspiring versatility! Set the over-edge thread length – at the twist of a knob. A serger with a chainstitch, four coverstitches and four combination stitches (chainstitch/overlock stitch). The hard-wearing safety seam (combination stitch) is ideal for reliably joining firm woven fabrics, such as jeans. The 3- and 4-thread coverstitch gives you an especially durable, flat stitch in highly elastic fabrics. The BERNINA lay-in system lets you thread quickly and directly – and it's also simple to thread the lower looper, thanks to the automatic lower-looper threading system. Easy, ergonomic operation: With the aid of the vision panel and the red position indicators, you'll find the ideal position of the needles and lower looper for threading straightaway.
