Juki DDL 8300

Ok, just unpacked my new machine and threaded it for the first time. The top stitch looks great but I turn the fabric over and it is a mess. The top thread is all bunched up in the back. Can't even see the bobbin thread. The so called Juki manual doesn't help one bit. Please advise. I think I threaded it incorrectly.

You need to do a tension test.
Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} Tension assembly test. To do this test. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)
If it doesn't do this you ned to rethread it through the tension discs and make sure the thread is between the discs.

Why wont my Juki DDL-8700 form a stitch?


machine is out of time and u probably have burrs on the hook since you broke the plate with a needle probably from pulling fabric and bending the needle. you instruction manual will tell u how to time machine and its really very simple. all u have to do is take off feeder plate, loosen the 3 screws that hold the hook then lower the needle with the wheel until the needle just starts to rise. bring the loose hook point to i/16 " fron the needle and tighten hook screws. machine must be tilted back to do this whole operation. it helps to have a short screwdriver to tighten the hook screws. remove burrs with lite emory paper stroking in the sale direction as the hook.

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
Is there a diagram for how to thread on the inside of the door ?

Follow that slowly and carefully to make sure you have not missed any thread guides on the way, as each one needs to be followed through to ensure correct tension and thread progression.

Cheerup and Be Happy always

I have a 2011 Juki DDL-8300N. Has always worked fine but while sewing on denim it suddenly seized up and stopped sewing. The needle is in the lowest postion through the jeans. I am unable to turn the


Your needle probably bent and got jammed. clip threads top and bottom of the fabric and remove... then get in the bobbin area and look for issues.

My bobbin stitch is too tight on my Juki DDL 8500-7, how can I fix this?


Hi LJ,
Look on the bobbin case, and see if there is a small screw. Usually that is the tension of the bobbin. You can adjust that until there is only slight tension on the bobbin thread.
Hope this helps

Hello, I have a juki DDL 5550, runs great, But the tension is off. Top thread bunches up on bottom side of fabric ( bobbin thread looks ok)\r\nThanks,S


Soulds like your not geting the top thread all the way in the tension disk. Make sure you have the presser foot up when you thread the machine. also after you get it treaded check to make sure you have tension, with the presser foot up you should have not tension and with it down it should be very hard to pull.
hope this helps

I bought a second hand Juki industrial machine , model DDL 5550-7, but struggle to get the tension of the stitches right. where do you set the lower stitches tension


upper tension sets the lower thread tension (upper thread is what you see on the underside of the fabric). Bobbin tension is for the thread you see on the top of the fabric
