ABSTRACT:
A control device for a machine has a control lever operative to rotate about two axes. The control lever is rotatably mounted on a shaft within a frame and is in communication with a first rotation sensor to detect movement of the control lever about the first axis. A first pair of adjustable abutment members are operative to center the control lever within the frame. The control lever and frame are operative to rotate about the second axis. A second rotation sensor is operative to detect movement of the control lever about the second axis. A second pair of adjustable abutment members are operative to center the control lever and frame within a stationary housing.
