The machine appears to be complex, with various components and parts that the men are adjusting and fixing. The men are using tools and their hands to manipulate the machine, and they are focused on their work. The video does not provide any audio or additional context, but the actions of the men suggest that they are skilled workers who are familiar with the machine they are working on.
