Establish machine identity before procedure advice
Use model, serial range, configuration and installed options when they affect the answer. A similar series name is not sufficient. If identity is unknown, request the appropriate label information or route the question for confirmation before presenting a model-specific action.
Build an approved source register
Record manual title, document revision, language, applicability and owner. Separate current instructions from obsolete or unresolved material. Service notes can be useful, but a note for a particular installation should not silently become the general procedure for every customer.
Make the source visible in the answer
A useful response names the document and relevant section, links to the permitted source and explains why it applies. Check that the citation actually supports the answer. A genuine document link attached to an unsupported conclusion is still a wrong answer.
