An Evaluation of Service and Repair Manual Design

Sixteen mining equipment service and repair manuals were evaluated, not for technical content, but for several variables important to the human factors design of the manuals in accordance with Society of Automotive Engineers (SAE) Recommended Practice J920, Military Specification Mil-M-38784B, and other significant research findings on these design variables. Interviews with maintenance workers in the mining industry were also conducted. Recommendations are identified which could improve existing manuals and the industry standards which have been established to guide them.
