CONTENT OF THE LESSON

INTRODUCTION

We use many tools, machines, furniture, bicycles, school desks, and household items every day. If these items are not cleaned, repaired, or stored properly, they may become damaged or stop working.

Taking good care of tools, machines, buildings, and other equipment helps them last longer and work safely. This process is called maintenance.

There are different types of maintenance, and each one helps to prevent damage, reduce repair costs, and keep equipment in good working condition.

In this lesson, pupils will learn the meaning of maintenance, the types of maintenance, and the importance of maintaining tools, machines, and other property.

MEANING OF MAINTENANCE

Maintenance is the process of taking good care of tools, machines, buildings, equipment, and other property to keep them in good working condition.

Maintenance includes cleaning, repairing, servicing, lubricating, and storing items properly so that they last longer and work efficiently.

TYPES OF MAINTENANCE

1. Preventive Maintenance

Preventive maintenance is the regular care of tools and equipment to prevent them from getting damaged.

Examples of Prevention Maintenance include:

• Cleaning tools after use.

• Oiling moving parts.

• Tightening loose screws and nuts.

• Storing tools in a safe, dry place.

2. Corrective Maintenance

Corrective maintenance is the repair or replacement of damaged or faulty tools and equipment to make them work properly again.

Examples of Corrective Maintenance include:

• Repairing a broken chair.

• Replacing a damaged handle on a hammer.

• Fixing a leaking water tap.

• Replacing worn-out parts of a machine.

3. Preventive Maintenance

Predictive maintenance is the type of maintenance in which tools or machines are checked regularly to detect problems before they break down.

Examples of Predictive Maintenance include:

• Checking a machine regularly for unusual sounds.

• Inspecting a bicycle to see if the tyres or brakes need replacement.

• Looking for cracks or loose parts on a tool before using it.

• Testing electrical equipment to ensure it is working properly.

IMPORTANCE of MAINTENANCE

1. It keeps tools and equipment in good working condition.

2. It increases the lifespan of tools and machines.

3. It prevents accidents and injuries.

4. It reduces the cost of repairs.

5. It saves time and money.

6. It improves efficiency and performance.

WAYS OF MAINTAINING TOOLS, MACHINES, AND HOUSEHOLD ITEMS

To keep tools, machines, and household items in good working condition, we should:

1. Clean them regularly after use to remove dust and dirt.

2. Store them properly in a clean and dry place.

3. Oil or lubricate moving parts to prevent rust and reduce friction.

4. Repair damaged parts immediately before the damage becomes worse.

5. Replace worn-out or broken parts when necessary.

6. Use tools and machines correctly according to their purpose.

7. Inspect tools and machines regularly to detect faults early.

8. Keep electrical appliances away from water to avoid damage and electric shock.

9. Tighten loose screws, nuts, and bolts to keep equipment firm and safe.

10. Handle tools and household items carefully to prevent damage and accidents.
