Hey all,
Greasing the gears is a different process than oiling the machine. Your OWNERS manual tells you where to put oil, but they generally don't tell you about greasing the gears because the assumption is that if they need greasing that will be taken care of when the owner takes the machine in for it's annual tune up.
Patricia, have you checked with Juki to see if they will let you have a copy of their SERVICE manual? That will probably tell you if the gears need greasing and if so, how often.
