General threading information A color coded diagram is located inside the front cover for quick reference. Always start threading the upper looper, followed by the lower looper and then the needles from right to left. See the table below for recommendations on what needles and thread to use for different fabric weights. Tip: Your new machine is threaded to sew a standard overlock. Tie your own threads to these threads and carefully pull them through the machine, to easily thread your new overlock machine the first time. Re-threading if a thread breaks If the two loopers are not threaded in the correct order they will not create a stitch. If a looper thread breaks always do the following: 1. Unthread the needle(s) 2. Unthread the loopers 3. Thread the upper looper 4. Thread the lower looper 5. Thread the needle(s) from right to left The following pages give you detailed step by step instructions on threading. Fabric Needles Thread Light fabric (voil, crepe, georgette, etc.) #12/80 Polyester (spun filament) Twisted thread #60/2 - #100/3 Twisted thread #80/3 - #100/3 Medium fabric (cotton, chino, wool, satin etc.) #14/90 Twisted thread #60/2 Heavy fabric (denim, jersey, tweed etc.) #14/90 Twisted thread #50/2 - #60/2 Note: When using standard thread spools, place the thread unreeling disc as shown to prevent the thread from getting caught on the edge of the spool.
