Juki MO-655 Mechanical Sewing Machine - Page 9 Questions & Answers
I have a juki 560 - wheel is moving manually, but gets hard to move at one point and then goes fine after that. The footfeed is not moving the material through. what could be the problem?
- Remove the foot and plate. Take your thread out of the needle and see if you can run the machine and it turns freely, if so:
- It sounds like you might have your feed dogs in crooked or your plate may be bent. Have you taken them out lately? Or bought a new plate that might not be the right one to match with the feed dogs that are in your machine?
- Take your plate off and examine it to make sure it is flat and that the metal between the feed dogs aren't bent. If they are bent, straighten them with your screw driver. If the plate isn't flat, lay it on a flat surface that you won't hurt (cutting board, workbench, garage floor :) ) and use a hammer to beat it flat (usually a couple hits).
- Lay the plate in place without putting the screws back in and wind the hand wheel forward and see if your machine is still hanging up. If not, put the screws back in the plate, put your foot back on and see if it works!
Juki 5550-6 bottom stitching has little loops every few inches What to do?
- Frances, Check to make sure that you don't have a bad needle. If there is a slight burr on the point of the needle, it will cause this. Or if your needle isn't in straight.
- If you have broken a needle, you may have a groove on the inside of the needle hole in your throat plate. You can take your plate off and buy emery string to run back and forth to smooth that out or you can buy a new plate. (look under your plate and there should be a number engraved on your plate to guide you into purchasing the right plate.
- Check your bobbin to see if its wound evenly and that there aren't any grooves in the edges of your bobbin (if there is, throw it away).
- Lean your machine back and run your finger along the outer edge of the shuttle to see if there is a rough edge that might be catching the thread as it revolves around. If there is, buy a piece of fine emery paper at a hardware store and buff it smooth
- Are you using smooth thread and a big enough needle? If your needle eye is too small for the thread or the needle is too small to punch a big enough hole in the material for the thread to pass through easily, it will sometimes cause skips like this.
- As a last thought, try a different foot. If your foot doesn't hold the material tight to the feed dogs while you are sewing, the material will 'follow' the needle up and down and cause skips.
- Good Luck!
I have a juki ddl 8700h when reverse its skipping how am i going to fix it
Generally the machine is making poor stitches going forward before it makes skipped stitches going backwards. Start out by correcting any tension imbalance first. Then:
- I usually start with the simplest thing first. Put in a new needle and make sure the eye is straight so that the scarf of the needle is meeting the hook properly.
- If it still skips, I look for places that there might me a flaw in my thread path. 1.) Is the thread coming off the cone properly? I follow the thread all the way to the needle to make sure its right. 2.) Did you break a needle lately? If so, it might have made a groove in the needle plate at the hole which you can sand out. Then, lean your machine back and run your finger around the edge of your hook. If there is a rough spot, use a piece of emery paper to smooth it out. 3.) Take your bobbin out and check to make sure that there aren't rough edges to the bobbin(throw it away if there are), then put a bobbin back in and see if the thread pulls out of the bobbin holder smoothly.
- Then, I look at the underneath of the foot I am using to see if it isn't holding the material to the feed dogs firmly. If the foot is allowing the material to move up and down slightly with the needle, you will have 'flagging' and that causes skipped stitches.I generally try a couple different feet and see if it stops the problem.
- Lastly, be sure that your needle and your thread are compatible with the material you are sewing. If you are using a needle that is too small to make a proper sized hole in the material for the size of the thread, you might have enough stress on the stitches to cause the skipped stitches.
- Good Luck!
Brand new juki 1508NH when replacing the throat plate and notch is in correct spot the bobbin only turns half way.Tried to remove screws to take out case they won't budge
Oil generally helps. Put a couple drops of oil on screws and let set a while.
- HOWEVER, If you have had a thread stuck in your bobbin, it may have used its safety feature to keep you from ruining your machine.
- Tip the machine back and use flashlight to make sure that your bobbin case is either out of the machine or in the machine correctly. If you think you have a thread hung up in the hook, take out the bobbin case, put a drop of oil where the hook moves and if there is a thread in there I usually use needle nose pliers to pull it out. It sometimes takes a few minutes to work it loose.
- NOW put the machine back down. There is a small button in the middle of the bed of the machine, about half way between the needle and the reverse lever. Push down hard with your left hand on the button and hold it down while you are turning the hand wheel towards you slowly. You should soon feel a click on the button as the machine goes back into sewing mode.
- Put your bobbin and bobbin case back in, pull your thread up and test sew.
Good Luck :)
How to oil juki MO 2512
There is a clear oil gunge cap on top of the machine.It probably is clear and has a small red line on it. Grab hold of it (if it hasn't been oiled in a while, you may have to use pliers to twist it counter clock wise. If you do, put a small scrap of material between the plastic cap and the pliers so that you don't make rough places on your cap.). Once you have taken the cap all the way off, fill it with sewing machine oil (not car oil, not WD-40, etc.)
When you are pouring it in, be slow. The actual oil gauge is on the right lower front. Pour only enough oil to be between the two lines on your gauge window. If you over fill, it will bubble out the bottom, run out the bottom of the machine and go all over your foot pedal etc .Irritating but not a crisis.
Be sure to put your cap back on securely before you try to run it or you will be cleaning up all around your machine and you may get a shower also.
Once your machine has oil, run it fast every so often and the oil should bubble up in that top cap as you sew. If it doesn't, you may need a new oil pump.
Good Luck! :)
I took the bobbin case holder out of my Juki machine and can't get it back in. Any tips?
- Make sure that your bobbin is all the way into the case
- Make sure that your needle is up out of the machine
- The half circle that is cut out of the bobbin case always goes towards the top.
- When you grab the tab on the bobbin case to put it in to the machine, it keeps the bobbin from falling out while you are trying to get it into the machine.
- If you still can't get it in, take a flashlight and look at where you are putting the bobbin case. Sometimes the thread from the spool on top has wound around inside the hook and won't let your bobbin case go in. If this has happened, you need to take a sharp pair of scissors or seam ripper to cut it out and then clean all that thread out and try it again.
Good Luck :)
Timing a juki ddl 555 and how to set needle bar
- I am surprised that you have to set the needle bar but put a NEW needle in the bar or make sure that the needle set screw is to the right side of the bar
- If your needle bar is already loose, there should be two small lines about 1/4" apart on your needle bar, where you can see it between the needle and the underneath of the machine.
- The needle bar height is set when the top line is flush with the body of the machine. Tighten your needle bar screw.
- Now wind the hand wheel towards you until the 2nd line is flush with the body of the machine. Push your machine back so you can see the hook. Set the tip of the hook one thread away from the scarf of your new needle and in the middle of the needle. Tighten the screws on the hook, put the machine back down (make sure that you have put your bobbin case back in) and test to see if you can pick up a thread when you wind your hand wheel towards you.
- If you are not picking up the thread, I find that I have to put my throat plate back on to pick it up most of the time.You may have to redo this several times especially if your hook is old and worn. It's possible but harder.
- Good Luck. There are a couple people on youtube showing how to time a sewing machine. They are all pretty much the same. It doesn't have to be someone who is especially trying to time a 555,
I have a Juki DU1181n and y corners when attempting box stitches. I am using a netted nylon fabric.
It is generally because you have not taken your knee completely off the knee lift.
Whenever you use your knee lift, it opens the thread tension and lets out more upper thread.
If you find out you are not leaving your knee on the knee pedal, try to only lift the foot as little as possible when you do your turn. I find out that when I am in a hurry I leave my knee against the knee lift as I am sewing and I have the same problem.
Good Luck. :)
Second needle keeps dropping thread. What to do?
Check to make sure that your needle is completely inserted up into the machine, and that it is straight with the proper side towards you (just in case you don't know: the 'ditch' that runs from the eye of the needle all the way up the needle to the part that inserts into the machine, is the front of the needle).
Check to see if the needle is the proper size. A wrong length needle or a size that is much smaller than you had been using (say you had been running a size 18 and decided to go down to a 12 for finer fabric) will sometimes require resetting the looper because it isn't able to grab the thread because the needle is too far away..A mechanic needs to do that.
Last but never least, you may have hit the end of the looper and chipped the end. If you have done that, unfortuneately they don't heal them selves and you will need to............you guessed it!.....call your mechanic.
Once in a while, there is a rough place on your plate or the wire on the tension for that thread has a small groove cut in it from the thread and you would need a new wire in your tension,
Look at the needle problems first.If your machine was sewing fine before, it is probably the needle, If the machine is new to you, the other things could be the problem.
Good Luck, :)
How to thread a juki cp 180
I am surprised that I couldn't find threading directions in the manuals that I found. It appears to me that you can thread it the same way that you would thread a Juki DDL 555 or DDL 8700. Manuals on Line have several manuals but I couldn't find threading directions in them. Weird. Most sewing machines thread similarly whether they are home or industrial machines. Once in a while there will be an odd one. Sergers, etc are another matter but sewing machines are generally alike in their threading.
My Juki 2200 sit down long arm is not grabbing the bobbin thread..help!
Did you get this fixed?
Most common problems:
1. You broke a needle and the hole in your needle plate now has grooves cut into the edges of the hole that are grabbing your upper thread and holding it too long for the hook to grab it. Take your needle plate off and examine it closely with a magnifying glass. If there are grooves, purchase some emery cord and run it back and forth until the edges are smooth or buy a replacement plate.
2. You broke a needle and you have rough edges on your hook. Lean your machine back and examine the hook with a light. If there are rough spots on the edge of your hook, you will need to smooth them out with emery cloth.
3. You have either the wrong size needle or you have the needle in backwards or not perfectly straight and the hook can't pick it up each time.
4. Have you changed to pre-wound bobbins? They may not be large enough for your bobbin case. If you have regular bobbins, check to make sure that the bobbins don't have burrs on the edge of the bobbins. If they do, throw them away and buy new bobbins. Sometimes I get some bobbins that are not quite round. Weird but true. Examine them.
Good Luck.
