Check the tension unit, when you use your knee press a pin should open the tension discs then return to normal, check for any fluff in the discs as well

SOURCE: 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.

SOURCE: I have a Juki DU-141 with a tread tension issue.

If you are putting too much fabric for the machine to sew this will happen. Does it sew any other fabrics? Some machines....even many commercial machines.........will not sew real heavy fabrics. Any thing over 1/3 of an inch and thats probably the case.

SOURCE: Hello, I have a juki DDL 5550, runs great, But the

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

How can I run pressure foot selector switch


Pressure on foot is regulated by the screw on the top of the machine directly above the pressure foot bar. Make sure your lever on back of machine is down, then turn the screw by hand, left for less pressure and to the right for more pressure.

Has anyone adjusted the presser foot inside the machine? That can throw it off or sometimes you need to look under the machine head into the oil pan to make sure there isn't something stuck and holding the pressure up from there.

Is this a new or used machine? Does it have enough oil in the pan?

How do I tilt my machine back to access the oil pan? The knee lifter bar is in the way and hit when I try to tilt my machine.


I don't know if you were the person that I was just writing to or not. I didn't think about the knee lift. I generally sew on a Juki DDL-5800 and we don't have the knee lift problem. I have an older walking foot with the knee lift. You might try what works with that one. Grab the front of the knee lift, push it towards the back and at the same time pull it up and left. There is a metal peg at the back of the shaft that will release and let you pull the knee lift out so that you can push the machine back. If that doesn't work, see if you can contact me and I can call someone else to find out.

Pressure foot will not lift up


do u have an automatic machine meaning ft is lifted by pressing ft pedal a certain dirtection. otherwise tilt machine and push knee lever. there should be a flat oval piece on top of lever rod. does it rise straight? it needs to contact the push rod on the machine presser ft. see if the line up by lowering the machine slightly. if not bend rod to aglin. your knee lift may need adjustment too and maybe the presser ft screw located by removing the rubber plug on side of machine or take off the plate by removing 3 screws. careful with gasket cause machine will leak if u tear gasket.. presser ft screw is easy to find. lower ft and tighten. make sure that the needle is centered in foot slot when adjusting presser ft screw. otherwise thread will break when needle hits side of presser ft. a very common problem that many do know about and someday i will charge the site. 35 years with juki and still going strong.

Problems when sewing over heavy jean hems


Are you using the correct type of needle? have a word with your needle supplier and explain the problem. Different threads and different thickness material need different top and bottom tension adjustments.
Can I suggest sew one thickness material at a time with tension adjustments for that thickness. Then change the tensions and do a batch of thicker material.
