Product Overview

The new air threading system makes it effortless to thread your machine. Combined with the built-in needle threader, this feature saves time for seamless sewing. The 8-piece feed dog system ensures smooth and perfect feeding of all types of fabric.

The Elna Easy Air 864 Professional is our first air thread serger and the easiest Elna serger to thread. Elna’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 specialty fabrics is a breeze, the 8-piece feed dog allows fabric to smoothly feed under 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 serger. 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. Safety, is important, the serger will not operate if, any covers are open, the sewing foot is raised or if the air thread mechanism is engaged. Another industry first is two ball bearings on the main shaft which provides low torque, making this Elna serger powerful and stable when operating, even at high speeds. All of these features are specially designed to make the Elna 864 Easy Air serger the easiest to use on the market today.
