Hi guys
sorry for another dumb question from a newbie but i don't understand why the fill pressure manometer has 2 pointers..
i thought it would have just one pointer -for me to tell the pump at which maximum pressure it needs to stop pumping but what am i supposed to tell the compressor with the second pointing arm- the minimum pressure... what for?
