1. Preventive maintenance is a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures. The primary goal of preventive maintenance is to prevent the failure of equipment before it actually occurs. Designed to: Preserve and enhance equipment reliability by replacing worn components Ensure machine failures are not the cause for workplace mishaps.

2. Reduced production downtime Conservation of assets and increased life expectancy of assets (both machine and human) Ensuring all equipment safety features are functioning properly Reduced cost of repairs by reducing secondary failures Quality products Identification of equipment with excessive maintenance costs 3. Damage to nearby equipment during a PM task Damage due to an error in reinstalling equipment into its original location Damage due to the installation of new parts. 4. Ensure equipment meets manufacturers specification Review job hazard analysis (JHA) to ensure equipment alterations or equipment maintenance did not introduce new hazards Conduct machine checks to ensure all features, especially safety devices, are functioning properly Ensure employees are aware of any changes to equipment and/or operating procedures. 5. Scheduling: Should be automated to the maximum extent possible Execution: Should be done before an actual break down occurs Quality: Should have a formal process for checking the quality of repairs. 6. Cleaning Lubrication and inspection Correcting deficiencies Operation of safety devices. 7. Structural/facility Age exploration programs Statistical analysis Safety inspection data. 8. Establishing effective training programs Establishing inspection and preventive maintenance as a recognized, important part of the overall maintenance program, including follow-ups Assigning competent, responsible people to the preventive maintenance program Setting high standards Publicizing reduced costs with improved up-time and revenues and employee safety, which are the result of an effective preventive maintenance system.
