300 SEL 3.5

My latest Benz is a 1970 300 SEL 3.5.The next one will be the 6.3. I need to know draining the air tank.I also understand there is a air fill schrader valve to fill the tank up.Where is it and to what pressure ect?The only think I can see is a compressor type fitting on the bottom.it is spring loaded.Also how do you check the compreesor output as the car will not rise.The car has only dropped when sitting, several mm in a week but will not rise to the level when I first got it.The compressor intake makes a soft thucka thucka noise and draws very slightly.The car will not rise when the height knob pulled,and the pressure light stays off in normal position.Do I have to put alchohol or metho in the receiver and how much? Thanks for everones help in the past,
