you need to provide the name and model of the overlocker, so someone can help find a threading diagram

Search the internet for:
Manufacturer + Model + the word "Manual"

or search YouTube videos for "sewing machine threading." You may not find your exact machine, but many machines have similar threading patterns. Be sure to raise the presser foot before threading the upper thread so it will seat properly in the tension disk.

If the thread is breaking at the needle, it could be several problems:
Threaded incorrectly--#1 cause
Upper tension too tight
Install a brand new needle compatible with the fabric & thread
Make sure the thread is not too large for the needle eye
Avoid old, fuzzy, bargain bin thread

The inside diagram is for the loopers. For the needle threads, just follow the color coded dots.

I also own a Juki MO3716. It is a five thread not a four as it has three lower looper threads. Two are fed through the front, just follow the color codes and the threading diagram on inside plate that you lower to see the threads, the third is threaded through the back and around the left side. I can send email with picture of diagram if needed. the other two threads are for the two top needles. This machine is a true safty stitch with the overedge row of serging and an inner chain stitch row for secure seaming. You can run this machine quite nicely with only three thread ( one inside needle and the two front loopers. If you need further held email me at [email protected]
