I recently bought a used JSW 120T electric (J120ELIII), which arrived with no manual. I have a manual on order, but it's a 30-day wait from Japan. In the meantime, we are doing a pretty good job just figuring everything out, and have already run a few jobs successfully. One thing that has us really scratching our heads, though: How do you tie in knockout bars to do repeated ejection? Seems there is not enough space to reach in and connect KO bars to the butterfly plate, b/c of the eject servo & belt. Is there a tricky way to do it?
