Abstract The five-hundred-meter aperture spherical radio telescope (FAST) is a key national research facility built by China during the 11th Five-Year Plan period. FAST is the world's largest and most sensitive single-aperture radio telescope and has significantly contributed to astronomical research. The operators seek to guarantee that the FAST facility runs smoothly and efficiently to improve observations and data quality. Focusing on the analysis of the structure and working principle, maintenance system, and maintenance content of the FAST equipment, this study takes the actual FAST engineering maintenance case as the research object and thoroughly analyzes the basic situation and process of engineering maintenance. The findings reveal existing flaws in the current FAST equipment maintenance program, as well as enhanced maintenance procedures for future maintenance work, aiming to improve FAST observation times and service life. This article also provides recommendations for future repair and upkeep.
