You may find some useful material if you do a web search for the words: Millwright guide. The person who sets up and maintains the equipment in a mill is a millwright. Another term is "Industrial Mechanic." The verb form appears to be millwrighting. Audel's has a Millwright and Mechanics Guide.

These are some older books on the topic, in no particular order:

The UnionMillwright.com web site is maintained by a retired millwright and you may find some other useful info there. Heck, he might even answer questions if you send him an email, but I don't know him.

Canada makes some training info available here: Industrial Mechanic (Millwright) Red Seal Occupational Standard (RSOS) 2017 / Red Seal

Good luck and let us know what you find out!
