I know your all going to think I'm nuts, but I finally used my milk machine tonight. Anyway I have a dilemma, I have a Hambys milker that will milk two goats. I took off one of the claws and plugged all the holes as to only use the one claw. I called and that's what they told me to do. Anyway, it says to have the lever on the claw UP for milking and DOWN for washing, though when I swished it in the bucket of water to clean in between goats, it sucked up a whole bunch of water. So I'm confused (easy to do). So reading this pamphlet over again (and over and over.. you get the idea) it says that when taking the inflation off of the goats teat, the rapid inlet of air creates a pressure difference across the valve which sucks the valve against its seat, creating immediate shut-off. So.. what do you do to swish it in a cleaning solution in between goats? do I need to turn the pump off each time?? I just dumped 3 gal of milk down the sink.
