Skipping stitches and breaking thread

SOURCE: My thread is breaking when

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: how do i stop juki ddl from top skipping stitches?

Hi. Skipped stitches are usually caused by a mismatch in your thread and needle. Wrong thread type, wrong needle size, or even old thread can cause skipped stitches. If all else fails, change the needle. If that doesn't work, clean the machine. Sometimes just getting rid of all the lint and giving her a good oiling does a world of good.

Let me know if this works.
