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

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.

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. ...

Search the internet for your machine manual-- "Manufacturer Model Manual" ie Elna 1500 Manual ...

Try unthreading the machine, oiling the hook and turning the handwheel firmly backwards.

Search the internet for: Manufacturer + Model + the word "Manual" ...

try using a pair of tweezers to get the ends of the thread while pulling the thread manually turn the machine backwards so that the thread unwinds as you pull it out other than that you may have to take it in for a service where the mechanic can remove items to get the thread out that service may not be covered by warranty but that will depend on the mechanics attitude to wanting your business
