Tested and Confirmed Baby Lock 3-thread serger Itotori Monogatari BL251 (Made in Japan) The threads attached in the photos will be included. Each part has been oiled, inspected, and maintained. Both regular overlock stitching and rolled hem stitching have been test-sewn and are in good condition. LED light has been replaced. [Just Fit System (Automatic Thread Tension)] The machine automatically adjusts the tension of the three threads, which used to require the unique skill of a serger! Even if the fabric thickness changes mid-sewing, you'll get a beautiful finish without any adjustments. With this, you can achieve professional results from the very first use. [Air Threading System (Automatic Air Threading)] By simply pressing a lever, the air pressure instantly threads the needles. This revolutionary system makes threading the loopers, which used to be troublesome, easy! [Easy Threading (Automatic Needle Threading)] Threading the needles is also easy. [Differential Feed Function] Beautifies the finish of stretchy knit fabrics and bias cuts. Also effective for gathering. [Safety Stop Mechanism] The machine automatically stops when the front cover is open or the presser foot is not lowered. 《Specifications》 ・Stitching Type 1-needle, 3-thread overlock serger Standard rolled hem Modified rolled hem ・Overlock Width 1-needle, 3-thread overlock: 3.0～5.0mm Rolled hem: 1.5mm ・Stitch Length: 1～4mm ・Sewing Speed: 1,500 stitches per minute ・Differential Feed Ratio: 0.6～2.0 ・Needle: HA×1SP ・Weight: 7.5kg ・Depth 280mm, Width 340mm, Height 290mm ☆Accessories☆ Foot controller, Needles (3), tweezers, small screwdriver, Cleaning brush, instruction manual copy, Replacement upper knife, bulky presser foot, Thread spool holders x 3 (set on the machine), 3 spools of serger thread in the image (set on the machine) I bought a replacement because I wanted a 2-needle, 4-thread machine.
