Janome’s push and blow type air threading system is an industry first. When threading the loopers, the thread is blown down the threading channel and through the eye of the looper. The needles are just as easy to thread, using the built-in needle threader which slides left and right, allowing the user to thread the required needle. Sewing speciality fabrics is a breeze, the 8-piece feed dog allows fabric to smoothly feed under the the sewing foot, plus grooves have been added to the sewing foot to help control challenging or slippery fabrics during stitching. The 5-level foot pressure dial is located on the top left of the overlocker. Integrating the stitch length and differential dials makes for easy and perfect adjustment for the fabric being sewn, whether sewing stretch to lightweight woven fabric. Adjusting the cutting width or dropping the upper knife, is all easily accessed in the one place, open the front cover and just the turn of a dial lowers the upper knife, turn again to re-engage.
