Preventive maintenance refers to routine, scheduled activities that aim to prevent breakdowns and ensure that equipment or systems run smoothly. It is based on the principle of anticipating problems before they occur.

Key Aspects of Preventive Maintenance:

• Scheduled Inspections: Regular checks and servicing of equipment or systems based on a set time interval (e.g., weekly, monthly, or annually).

• Lubrication, Cleaning, and Calibration: Ensuring machines and systems are well-maintained by lubricating moving parts, cleaning dust or debris, and calibrating settings.

• Replacement of Worn-Out Parts: Identifying parts that show signs of wear and replacing them before they fail (e.g., filters, belts, or gaskets).

• Reduced Downtime: Helps reduce unplanned downtime by addressing issues proactively.

• Increased Lifespan: Helps extend the lifespan of equipment or systems by maintaining them in optimal condition.

Benefits of Preventive Maintenance:

• Minimizes costly repairs due to unexpected breakdowns.

• Helps extend the lifespan of assets and equipment.

• Increases system reliability and reduces production stoppages.

• Enhances safety by identifying potential hazards before they cause accidents.

2. Corrective Maintenance (CM):

Corrective maintenance is performed after a failure or breakdown has occurred. Its purpose is to restore equipment or systems to their normal operating condition.
