My Juki DDL 8300n unthreads itself

SOURCE: Juki 8300N

Dear Rosemarie,

Make sure you have threaded the machine from right to left, it sounds like the needle thread is trapped under the lower looper thread and cannot form a stitch.........start the threading over from scratch like this:

1. Lower Looper
2. Upper Looper
3. Left Needle
4. Right Needle

im no expert, just been sewing for many years, i use 2 different juki machines, i suggest looking at the needle, are we sure you have the rite size? 135/ 140? did the needle just get changed? it could be the correct one, but if its in backwards, there isn't a dimple to let the hook behind the thread, to catch it, feel free to call me, 239-895-4845, my name is devin, shop is Quality Auto Trim Inc., ill try to help you over the phone if necessary, good luck

perhaps you have the wrong needle or its not in the proper position?

Hi,

I do understand sometimes the manuals do not give a complete picture. Check out these videos that I have posted bellow. They show how to set it up.

Could you explain the problem a bit more. Sounds like a tension problem but it could also be a poor needle/thread match.
