3. Introduction to repair
 Repair is define as a To put something old or damaged back into good condition
 .Example

4.  Inactivity time get certain so equipment ability increase
 Maintenance regularly allow Bator flexibility
 Component life cycle extends
 Failure Rate decreases
Need of repair or maintenance

5. Maintenance Introduction
1. Plant maintenance is an important service function of an efficient production
system.
2. It helps in maintaining and increasing the operational efficiency of plant facilities.
3. Maintenance is the procedure of finding the faults in any equipment/Machine and
also removal of fault.
4. It may be before the breakdown or after the breakdown.
5. Plant maintenance usually refers to the methods, strategies, and practices used to
keep an industrial factory running efficiently. This can include anything from regular
checks of equipment to make sure they are functioning properly.
6. The general aim of plant maintenance is to create a productive working environment
that is also safe for workers.

6. Maintenance Objectives
1. To increase functional reliability of production facilities.
2. To maximize the useful life of the equipment.
3. To maximize production capacity from the given equipment.
4. o minimize the total production cost.
5. To minimize the frequency of interruption in production by reducing
breakdowns.
6. To enhance the safety of the manpower.

7. Importance of maintenance
1. It helps in identify the cause of failure , e.g whether the failure is due to design defect, or
a wear out failure.
2. It also helps in deciding the type of maintenance and maintenance decision like replace
and repair.
3. It provides the necessary information regarding the life and reliability of the equipment.
4. With the help of this tool spare parts management got initiated.

8. Different type of maintenance

9. Planned maintenance is a proactive approach to maintenance that focuses on minimizing
the downtime and costs associated with breakdowns. The process starts by identifying a
maintenance challenge you want to address, such as reducing downtime or increasing the
lifespan of your assets and equipment.
Planned Maintenance

10. planned maintenance key points
• Step 1: Identify a problem and create a work order.
• Step 2: Assess the worksite and the asset.
• Step 3: Detail the process to complete the work and order the necessary parts.
• Step 4: Assign the work order a priority level.
• Step 5: Schedule and complete the planned maintenance.

11. These can be further classified as
1. Préventive maintenance
2. Corrective maintenance
3. Prédictive maintenance

12. Preventive maintenance (PM)
 Preventive maintenance (PM) is the regular and routine maintenance of equipment and
assets in order to keep them running and prevent any costly unplanned downtime from
unexpected equipment failure. A successful maintenance strategy requires planning and
scheduling maintenance of equipment before a problem occurs.

13. Corrective maintenance
 Corrective maintenance (CM) involves the replacement or repair of equipment after it
fails. In response to equipment failure, CM tasks identify the failure (it may be an
equipment component or equipment item) and rectify the failure so that the equipment
can be reinstated and the facility production restored.

14. Predictive maintenance
 Predictive maintenance is a technique that uses condition-monitoring tools and
techniques to monitor the performance of a structure or a piece of equipment during
operation.

15. Unplanned maintenance
 Unplanned maintenance is any maintenance task that occurs unexpectedly. It happens
when there is no formal strategy in place to address a repair, replacement, or inspection
before it's needed. Unplanned maintenance is commonly the result of equipment failure
that was not anticipated.

16. There are some types of unplanned maintenance
 Reactive maintenance
 Corrective maintenance

17. Benefits of maintenance
1. Lengthen asset lifespan.
2. Lower risk of breakdowns.
3. Increase efficiency.
4. Decrease unplanned downtime.
5. Promote health and safety.
6. Boost customer satisfaction.
7. Save money.
