I have a EK8060 and it has a knob on top of unit in front of handle, I see models of it on the net, but when I download instruction manual, they do not show the knob. It appears to be how much steam that comes out of machine, not sure, with no manual I do not want to ruin machine by operating it wrong, also I have no fill cup or cap and don't want to overfill machine. Please help anyone, it would be greatly appreciated, I really need this machine to work asap, trying to remove wallpaper off of walls and ceilings in a hundred year old home. Sincerely, Dana
