Which tension is wrong
if thread is bunching up under material increase the tension of the needle thread if the bottom thread is loose then increase the bobbin thread tension
each thread result for above or below material will indicate which thread to alter the tension on

SOURCE: Tension settings juki mo-644d

-If the machine is threaded correctly and the thread is flossed into the tension discs,
-if the thread is high quality and not cheap thred
the top tensions should be at 5-6 and the looper tensions should be at 4-5
Be sure it is threaded correctly (follow the threading map on the inside of the front cover of machine
Also be sure you are using a size 14 or size 90 standard Schmetz needle do not use Klasse needles
as these are to short and affecdt the timing.

I have a new Juki LU 1508NH and I can't get it to pick up the bobbin thread. Any ideas?

There are a few things you can try -
1. Extend the bobbin thread longer outside and push it away from you.
2. When you make the Stiching pressure lever down then see whether it sits properly or is lose and creating gap.
3. Clean the bobbin seat. Check for its free movement.

Sewing machines i cant get my juki lu 562 to make a single stitch nothing

Try installing a brand new needle. If it still will not pick up the bobbin thread, the machine may be knocked out of time. Take it for service.

I have a juki lu 562. Adjusting stitch length. For some reason it will not go to 9, 10, , 11 on scale. Will not go any farther than 8, then turning wheel opposite goes to 12.

Turn it to either extreme and then see if the feed dogs hit the plate when you hand turn the hand wheel towards you. Sometimes the feed dogs or plate have been replaced and they have set the stich length so that the feed dogs won't hit the ends of the plate.

My Juki LU-563 stopped picking up the bobbin thread, changed needle, took out bobbincase to look for thread, none, still won't sew because of bobbin thread not being picked up.

If you've properly installed a brand new needle that is correct for the machine, threaded it correctly, checked that the bobbin is installed correctly and the bobbin tension threaded properly, most likely the machine is out of time. In other words, the needle is arriving at the bobbin at the wrong time in order to intercept the bobbin. (You can open the bobbin area, hand rotate the handwheel and watch how and where the needle moves in relation to the bobbin to see where and why it is not connecting.) You can search the internet for web sites and videos that discuss machine timing or you can take it for service.

The Bobbin Assembly will turn in reverse but not forward Juki LU-563

Most likely the bobbin retainer has been bent. Turn it over by hand with the power off and look carefully, you will prolly see it.

I have a Juki LU-562 sewing machine I was sewing thick leather it made this clunk noise and a spring flew out of it underneth it now the hook just turns and it doesn't sew.

Like most of the older sewing machines, the lu-562 is usually an easy fix when it comes to issues of timing and even broken parts. First determine where the spring came from and that should point you to the parts that need replacing and/or readjusting. But, by all means DO NOT continue operating the machine until its fixed. Without actually seeing the machine, it sounds as if the needle bar spring failed.
