Insert the center selector rod into the middle hole of the weight stack. Slide the top weight plate (the one attached to the cable pulley adapter) over the guide rods so it rests on top of the stack.
uses a sliding weight system that requires precise alignment. The light outside had gone syrupy; rain drummed
