I adjust so that my arm in the toll removal mode and when it goes back to rest the arm is setting about 10:00 and 4:00. That is in the direct path of the my Z axis. Kitamura said loosen the taper lock and move the arm so that it lines up. When I do that either the arm doesn't get to the tool to remove it (while in rest the arm is at 9:00 and 3:00 perfect). Or if the arm lines up at the tool then in rest it is at the 10:00 and 4:00 position.
