How to adjust the beer machine?

Adjusting the machine is a technical job that requires a master to take care of it on site. Simple words cannot explain it clearly. Even if there are detailed instructions, it still requires on-site operation and explanation by the captain, and you need to do more operations yourself and accumulate your own experience before you can adjust it properly. It can be seen from the positions of captain, second-hand, and apprentice that machine adjustment is a long-term process of accumulating experience. It cannot be simply explained. For different machines, the same method is used to adjust the machine. The results are also different. To adjust the machine well, one must understand the method, and the other is to understand the "temper" of the machine. These require you to accumulate experience yourself.
