Before all else. Turn off machine!
(1) break screws on the hook loose.
(2) tighten one back up very skightly, one you can reach when the needle bar is at its lowest position.
(3) lower needle bar to its lowest position.
(4) loosen the screw just tightened.
(5) position the tip of the hook behind the needle hole. the tip should be as close to the needle hole as possible without actually touching the needle
(6) tighten screws
(7) slowly hand turn the machine (depress the foot pedal to disengage clutch brake on motor) several revolutions to make sure the needle doesn't hit anything on the hook.
(8) if it passes this test, try on a scrap of fabric

MAKE SURE YOU HAVE THE RIGHT NEEDLE FOR THE THREAD YOU ARE USING, AND THAT THE SAME THREAD IS ALSO IN THE BOBBIN. CHECK UPPER TENSION, BY PULLING SLIGHTLY, IF IT'S TIGHT, LOOSEN THE UPPER TENSION.YOUR THREAD MAY BE THE WRONG SIZE OR TYPE FOR THE SPEED YOUR SEWING., and the needle your are using( sorry about the caps lock)

My juki 8700 h frays thread while trying to sew


Hello Daniel, I suggest you start with a new needle. Back off the needle thread tension and the bobbin thread tension to a minimum and see how it sews. If it does not ravel the thread, you can increase the tensions until you acquire the stitch you want.

My wife broke several needles on her Juki DDL 555 machine and I need to know how to adjust the timing as she put a new needle in and the point was damaged


First thing to check is if you've got the right needle system: http://partsbooks.sewingmachine.com/Instructions/Juki/Industrial/DDL-5550%20&%205530%20Instruction%20Manual.pdf and that the needle is correctly oriented... the scarf has to be precisely set.
The next things I'd check are the stitch cycle -- hand crank the machine through the normal stitch cycle and see what's hitting. Then fix that. I've got my suspicions this may be a needle bar height adjustment. Don't thread up for this test... misthreading can also cause the needle to hit something and break, so start with the fewest possible variables first.

How to set timing and bobbin in my juki ddl-555


hi there
when you need to set timing please first make sure height of needle bar is ok. there's two mark at needle bar, the upper one is for height of needle bar: bring the needle bar at lowest position and in this case the upper mark must be equal with lower needle bar bushing.
second : set timing
move hand machine pulley at the same rotation and when the lower mark equal with lower needle bar pushing the tip of hook must be at the center of needle groove and just light touch not hit. that's all
best regards

I have a Juki DU 141NH industrial sewing machine. I just had it serviced. I had to put a new bobbin in and now the needle is not catching my bobbin thread. Please help!


Be sure you have the proper needle - it is longer than standard needles, plus be sure that you put the needle in from left to right - not...front to back.

Juki Sewing machine DDL-555. After 4-5 hours use feed not moving


Sounds like as the machine builds up friction from extended use, some vital part is lacking lubrication and is seizing up. A good service person will remove ALL of the covers and thoroughly air clean and oil every moving part. Sometimes these dry points are hard to find and patience is required.

You can get a sewing machine oiler with a long applicator and put a drop of oil on anything that moves, but over oiling can be messy.
