Preventive Maintenance
The routine of time directed tasks foster discipline and focus in the maintenance organization. A well-designed program has a standard daily and weekly routine that encourages systematic planning and performance of maintenance tasks.
A PM system usually has several types of tasks. There are time directed, condition directed, regulatory compliance and failure finding tasks. There are also run-to-failure tasks, which don’t involve any work because it’s cheaper to fix the machine after it fails than to do preventive maintenance on it.
Time directed tasks are jobs like regular lubrication, preventive replacement of components and regular overhauls. Regulatory tasks are those mandated by laws and regulations. Failure finding tasks detect failures that would not show during regular operation, for example, the failure on an emergency generator or stand-by pump.
