Difficulty to do needle threading on S4D overlocker

Sergers are absolute "bears" when threading compared to sewing machines. If/when you get frustrated, walk away. It took me the majority of one day before successfully getting my first serger threaded properly. Using four different color threads is also helpful when learning the serger--especially when it comes to adjusting the tension.

It is very important to pay attention to the order the threads are threaded, as well as making sure the thread path for each is correct. (Consult your owner's manual as different brands will look different.) Most machines require that the upper looper be threaded BEFORE the lower looper because the lower looper thread will cross OVER the upper looper thread as the final step before going under the presser foot.

ALWAYS RAISE the presser foot when threading!!! This releases the tension disks.

Also, when threading through the tension disk, be sure to give the thread an extra little tug to make sure the thread seats firmly in the tension disk. (Grasp the thread just below the thread stand with one hand and then grasp the thread below the tension disk with the other hand and give a little tug--sometimes it will make a little popping noise when it seats.)

Start out with the tensions set at the midway point. From that point, you can test your machine to make sure it is serging properly. Then you can adjust the tensions to suit you or the project you are making.

If the either looper thread breaks or pulls out, remove BOTH looper threads and rethread from the beginning!!! Trying to finagle threading of only one thread will most often result in a machine that will not operate correctly. Just bite the bullet and rethread both threads (in the order specified in the manual).

I seem to have trouble using the tweezers to thread the looper eyes, so I use dental floss threaders instead.

One more hint: NEVER pull the thread out of the machine by pulling it UP through the machine. This could damage or wear the tension disks. Always clip the threads just below the thread stand, RAISE the presser foot, and then pull the clipped threads DOWN through the looper eyes and needles.

Be sure to clean and oil your serger frequently. This is very important to get the best performance from your machine. Use only fresh oil recommended by the manufacturer and apply only a couple drops each spot.
