A shot blasting preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the shot blasting fails. This page gives the schedule used in the PlantOps360 task library for shot blasting (/ sand blasting machine and booth), which follows common industry practice for general-purpose equipment. It is also searched for as sand blasting, grit blasting, shot peening, blast cabinet.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
