Hi there, gently tilt the head of your machine back and rest it on the white peg thing at the back. Inside you should see lines on the back side of the oil pan...min and max. If you are somewhere in between, all good. If not, add more. NOTE: always use clear machine oil. Any other stuff will stain your work. Hope this helps, have a great day

Hi there, no you cannot do a stretch stitch on the ddl-8700. It only has on stitch and it is a straight lockstitch.

Your table sounds like it was cut for a different machine..You might be able to move your motor over to where the belt will come straight down from the handwheel. There is some adjustment that can be made with a wrench on the large nuts that hold the motor up to the table. Good luck.

Carmen, Your belt is either twisted or is not down in the groove in the hand wheel or in the pulley that is on the end of your motor. Use a flashlight to look at the end of your motor (under your table). That is a common problem. Once you think it is probably on both the hand wheel and the pulley, start turning the hand wheel towards you about 10 times. Sometimes that helps it settle in. When this happens, the hinges sometimes get crooked and you will need to try to straighten them by jiggling the head of the sewing machine until it settles in. Good luck.

I looked everywhere on line that I could think of and couldn't find one. I have had luck looking for other parts I needed by watching ebay selling a model for parts. My go to mechanic is in Cleveland OH at the Geo. E. Johnson Co. Ask Herb or Jerry if they can order the part and have it sent to you.800-729-6341.

Your machine is out of time. This means that your bobbin casing is not rotating at the right time to be able to grab the thread from your needle. You should take it to the mechanic to have it fixed.

Any chance you broke a needle?
1. First take your feed plate off and then see if the hand wheel turns freely. If it does, look at the plate to see if it is bent. If bent, lay on a flat surface and tap with a hammer until it's flat and put is back on. If it's in bad shape, you will need to buy another one. This should also free up your back lever.

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?

Cut or broken? Broken is the tension is too tight on either the top or bottom. The needle hole may be too small for the thread you are using. Thread can be poor quality (look in light-is it fuzzy?)and breaking on it's own. The most likely is the tension must be adjusted.

I do not know why you never got one with the machine contact the vendor, BUT here is Threading Guide for Juki DDL-8700 Single Needle... on you tube. If you also contact them they should be able to give you info. Nice machine though.

if you know the model number, youtube is the best place to figure out how to fix the problem

possible over oiling, or if it has a reservoir to put oil in , then the reservoir may need to be checked for leaks

If it has been a while since the needle has been changed, doing so may be helpful. Also be sure to use a sharp needle that will more easily penetrate the zipper tape.

Be sure that you are actually lowering the presser foot before stitching (this most likely isn't the case--just a thought).

Most machines also have a presser foot pressure adjustment that can be loosened or tightened to accommodate different thickness of fabric and the amount of pressure applied by the zipper foot on the fabric and the feed dogs. Experimenting with that pressure adjustment may be helpful.

Some bobbin cases also have a finger extension with a hole through it. If you are experiencing issues with bobbin tension, sometimes threading the bobbin thread through that finger will help even out bobbin tension.

Using lighter weight thread will also affect the resulting thread tension. If the bobbin case is wound with light weight thread, the bobbin tension will not operate the same as it would with standard weight thread. Light weight thread in the bobbin will cause looser tension, but heavier thread will cause a tighter tension.

Technicians use a standard weight thread to test tension on a machine, but if you use a different weight thread, then your results most likely will not be the same.

Bobbin Tension How and Why Tension is Adjusted

How can properly adjust my tension

Understanding Thread Tension Threads


Most tension adjustments can be accomplished via the upper tension. However, there are times when the bobbin needs to be adjusted. Sewists are frequently nervous about adjusting bobbin tension. It is important to mark with permanent marker where the skrew-slot is positioned on the bobbin case BEFORE attempting any adjustments (at least if you need to return it to the original setting, you'll know where it was). Make only 1/8 turn adjustments at a time and re-test. (Righty-tighty, Lefty-loosey!) Sewists who frequently use different weight threads in their machine will often have an extra bobbin case that is set up specifically for that thread weight so they don't have to manipulate the bobbin case every time a thread is changed.

Consult your owner's manual. The troubleshooting section will usually list error codes and how to correct them.

If the error code is not listed in the manual, you may want to contact a Juki technician for advice.
