Yea, it actually tells you in the regular users manual, which is pretty cool. The long groove as in the scarf? It was my belief that you want the scarf facing the hook which would be right in this case. Do you know if the screw of the adjustment for the check spring is actually supposed to catch it? I figure it may be bent a bit since it seems like adjusting the plate that the screw holds under it does not seems to do anything, the spring is always stopped by the screw that holds it. Anyway thanks for your response, I do appreciate it a lot. +
