Following those instructions, I unscrewed the black knob, pulled out the red handle, and loosened (3 or 4 turns) the set screw. This, by the way, takes a 5/32 allen wrench, and has to be done by feel. But the chrome fixture doesn't pull off or even pry off. It seem fixed on the main part of the mechanism. Is this a corrosion issue? I assume you don't have to remove the set screw completely... Any ideas? (not enthusiastic about the sawzall solution)
