Juki ddl 555 knee lifter is not lifting the foot. How can I fix it?

The knee lifter first started to tighten up. Now it is almost impossible to use it. I have to push it so hard, it is painful. It lifts up the foot, but not all the way.

I imagine that it is the mechanical knee lift that you actually lift with your knee? Sometimes the screw that holds the knee lift rod comes loose a little and starts to slide in the holder. Sit on the floor where you can see the underneath of your table and use a wrench or vise grip to loosen the bracket that holds your knee lift bar with the pad on it. Move the bar to the left and retighten the screw and I think you will be ok. Sometimes if there is too much oil in your pan or you have moved the machine and some of the oil spilled out, a little oil gets out of the pan onto the bar and makes it start to slip. If that doesn't work we'll try something else.

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)

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.

HI I just bought a Juki. DDL-555-5 with cpu Juki MC210 and the machine work prefectly but CPU box is not working just type 0 on memory,How do I should fix it? I put a picture for more understanding.
Start out by making sure all your cords that run from the cpu down to the motor are plugged in tightly. Sometimes when you move it from place to place, they become unplugged slightly.
Did you test the machine at the place where you bought it before you purchased it? If not, it may not have been working before you bought it.
The machine working is mechanical and is independent of the computer for the most part. If the computer is bad, it will take a mechanic to fix it and some of those parts are no longer available, Whether the computer is bad or not, the machine should continue to work fine as long as you keep clean oil in the reservoir. Did it come with a regular knee lift on the machine? If not, and if the computer goes bad, you can put a knee lift on the machine and still use it as a good machine. Good Luck!

When i release the leg lever to let down the presser foot ,the foot wont release all the way and now it wont stitch
Mine does this too sometimes. Lift up the head and look in the middle of the oil pan. The knee controller runs through there. Make sure the black knob is not stuck. Hit the knee thing a couple of times to make sure it is not stuck. It should move freely up and down. That may fix the problem. If not, look st the small post to the left and behind the oil intake. Move the manual presserfoot lever on the machine to see it move. It will be stiff, but it should still lift a little. Usually jigging these two parts will fix the problem. Good luck..

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.

How can I fix the knee lift that is very hard to push
how much srping tension do u have on presser ft. is the tension knob on top of machine screwed all the way down., never necessary by the way. next your arm attached to the knee lifter may be bent and not contacting the lifter bar for presser ft. get under machine and move knee lift with hand to see where contact is being made. bend accordingly. also the link from knee lift bar to link inside the back of the machine may be broken. u have to take off the back panel with all its screws. watch the gasket. you can replace the bar yourself since this will not intefer with the machine timing etc.

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.

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
