Single source of truth per machine
A maintenance log is the historical record of everything that has happened to a specific piece of equipment over its lifetime. When the bearing fails on conveyor 3, the question "is this the same bearing we replaced last year, or a different one?" should be answerable in 30 seconds — which requires a maintenance log per asset. This template gives you a structured log format that any team member can fill consistently. Maintenance logs are essential for shift handovers (the night-shift technician knows what day-shift was working on), root-cause analysis (recurring failures show up clearly), and audit defense (auditors review historical maintenance evidence per asset).
