Equipment specification documents explain the design, functions, installation methods, and operational conditions of machinery and technical devices, etc. They serve users as well as engineers and managers for training and knowledge transfer.

Formats include manuals, specification sheets, and technical requirements. Translating without understanding the design and operating principles of the products may lead to misuse of the products or operational hazards. As such, accurate interpretation and expression by translators with knowledge of mechanical engineering and related fields are required.
