SOURCE: industrial sewing machine top thread breaking

The brother DB 2 series of machines do not use a needle with a flat side. the needle system is DBX1 and are available from size 10 to size 20.
Try using the right needle for the machine and the right size for the thread you are using. this should make it better

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

SOURCE: bobbin thread won't engage.

The bobbin case is not in the shuttle.

Raise the needle to it's highest position.

Lift the lever on the back of the bobbin case and hold it open as you insert the case into the shuttle; arm on the case pointing up. You may have to turn a bit to the left or right - it will click when in place.

I am using a Juki DDL 8700 thread to tight & not pulling through needle & cactching bottom thread


needle too small or machine out of time. to time machine theres a mark on needle bar. lower needle bar till mark shows and raise bar till even with bar guide. take off feeder plate so u can see needle in relation to hook. when mark on needel bar is even with bar guide the hook should be 1/16 fron passing the needle. if not loosen 3 screws and trial and error it to get it right. use a small screwdriver and tighten just on screw when u hab aglined the hook to needle. do a full rotation and watch where needle is and needle bar mark. needel should be as clost to hook without touching.

How do I stop my Juki DDL-8700 machine from skipping stitches?


set up on quilting table? wheres the oil pan?? if your machine sews fine straight and skips on curves i think you are lifting the presser ft as you make the turn. theres nothing wrong with the machine. you could always change the needle which is always the first thing when you encounter a sewing problem.

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.

Oily bobbin


Sounds like you've over oiled your machine. Take the bobbin out, strip the thread from it. wipe it down well... and re-wind the bobbin with new thread.

Next time you oil after your day of sewing. Place a piece of absorbent scrap fabric under the presser foot to catch excess drips.

My machine won't stitch, and the tensions seems to be very high, even after adjusting it.


Hi, if your bobbin has thread, check to make sure the bobbin is inserted into the shuttle correctly. If it is loaded correctly, check to see if the needle is able to pull the thread through the throat plate.
If it doesn't have thread, then all your sewing machine will do is make little holes because the bobbin thread is what catches the sewing needle thread to form the lock stitch to sew the material together . Check your manual on the sewing machine for where it is and how to put thread into it.
