I recently purchased a Juki DDL 8700, assembled it and am now ready to sew except that it won't sew a stitch. I thread it, pull the bobbin thread up and then attempt to sew...no stitches. The needle is not pulling the bobbin thread up. The directions are vague and no troubleshooting information is available.

Perhaps a manual would be helpful:

You should probably contact the manufacturer with questions. Hopefully, you did some thorough research before purchasing this machine. From the info I found, it appears to be a straight stitch only machine. I don't know anything about this machine, but I would be hesitant to purchase a straight stitch machine for sewing swimwear. Usually, swimwear needs a stretch stitch or zig-zag capability. Just my thoughts...

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.

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

Hello Daniel, I suggest you start with a new needle. Back off the needle thread tension and the bobbin thread tension to a minimum and see how it sews. If it does not ravel the thread, you can increase the tensions until you acquire the stitch you want.

try changing the needle to one that will work with heavier thread
you may have to change the bobbin to heavier thread also
try adjusting the tension also

YOU MAY SEE THREAD HANDLER HAVE SOME PROBLEM. THERE MAY BE SOME THREAD TON IN IT

Hi, if your bobbin has thread, check to make sure the bobbin is inserted into the shuttle correctly. If it is loaded correctly, check to see if the needle is able to pull the thread through the throat plate.
If it doesn't have thread, then all your sewing machine will do is make little holes because the bobbin thread is what catches the sewing needle thread to form the lock stitch to sew the material together . Check your manual on the sewing machine for where it is and how to put thread into it.

What bobbins do I use on a Juki DDL-8300
