Things You'll Need

  • 4 spools of thread
  • Sewing tweezers

The Singer 14u44 serger is a three- or fourh-thread serger machine manufactured in the late 1980s. It sews, trims and produces an overlock finish simultaneously. This serger sews twice as fast as a regular sewing machine, giving you a professional seam. The edge finish prevents raveling of the material. Threading a serger is a tedious task that requires patience. Always maintain the correct order of threading the machine.

Select the thread and place one spool on each of the thread posts at the top of the machine. Thread the machine in the following order: upper looper, lower looper, right needle and left needle. Extend the thread-guide pole to the highest level. Pass each thread through its pole thread guide from back to front.

Thread one spool at a time. Begin with the upper looper. Follow the red/orange color lines for the upper looper on the diagram. Ensure that the thread going through the tension dials seats firmly between the tension discs. Continue threading through the guides marked with a red/orange dot.

Thread the lower looper. Follow the yellow color lines for the lower looper. Pay special attention to the threading between the tension dial discs. Continue threading through the guides marked with a yellow dot.

Thread the right needle following the diagram and the thread guides with a green dot.

Thread the left needle following the diagram and the thread guides with a blue dot.

Pass the all four threads from the front to the back of the presser foot. Test the stitching using a scrap piece of material to ensure the threads are making a correct stitch.


  • Always thread in the correct order. Thread the needles last to avoid crossing the threads and causing the thread to break. Consult the printed threading guide on the inside of the access door to the looper threading area in the front of the machine. Each thread guide is color-coded and shows the path for each thread.


  • Turn off your machine while threading to avoid unintentional movement of the loopers and fabric cutting knife.
