1. Scrub the udder of the cow with warm water and dry it with a towel. Massage the udder in the same way as manual milking.

2. Move the milking machine to the back of the ventral side of the cow. And put the rope hanging the milk collector around the waist of the cow, and then squeeze the first milk of the four nipples into the small basin by hand.

3. Connect the vacuum hose to the fixed vacuum duct and turn on the switch, remove the breast collector at the same time, remove the three adjacent nipple hoses and hold them in your hand, turn on the milk inlet switch, and turn on the remaining milk. Put the mouth on the farthest nipple, then put on the other three nipples in turn, and at the same time pull one end of the hanging rope from the belly of the cow, and slightly tighten it on the hook of the breast collector.

4. Observe the milk entering into the milk glass tube. After a period of time, the milk stops flowing, which means that the milk has been squeezed out and the breast can be massaged again; if no milk enters the milk bucket, the milking machine can be removed. The sequence of taking the milk extractor should first untie the sling, then hold the milk collector, and turn off the milk switch on the milk bucket, remove the nipple from the nipple, turn off the vacuum switch, and remove the vacuum hose.
