Disassembly Notes

1. When removing the X table - either remove the spindle first -or- make sure that when you put the X table on a cart you use blocks to not bend the then very exposed spindle.
2. When removing the gearbox in the knee it is *crucial* to first remove the guiding pin. This allows you to rotate the unit some 10 degrees clockwise to lift the crownwheel. You *will* break a teeth from the crownwheel otherwise !
