NuPulse Milker Machine help

I just received my NuPulse Milker Machine and need some advice/help. How the heck do you attach the claw to the cow/udder. It does not seem to have enough suction to stay on the teat. I tried to hook up one teat and go the attach the next and the first falls off??? The instructions did not come with the machine They are in the mail though.

If you have one of these units how do you like it. Mine came with a huge 75#bucket. Will need a cart to carry that sucker back to the house

With the bucket milkers you will have to kink off all four inflation's to built up the vacuum and then carefully attach each teat without loosing your vacuum. I hope that makes sens. I'm not familiar with the brand but this is what we have to do with single bucket milkers at the shows.

Hmmm I wonder if they can be plugged. Dont think my hands are big enough to kink the four hoses lol. Will have to practice before I haul it back out
