Maintenance of Machines

Maharashtra State Board: Class 6

Maintenance of Machines:

Friction: Parts of machines rub against each other when they work, creating friction.
Dirt and Dust: Dirt and dust can get between these moving parts, increasing the friction and making the machine work harder, which can lead to damage.
Weather Effects: Rain, humidity, and other weather conditions can cause metal parts to rust and erode.

Basic Steps in Machine Maintenance:

Cleaning: All parts of the machine are wiped clean to remove dust, dirt, and grime. This helps to reduce wear and tear from friction.
Lubrication: Oil or another lubricant is applied to parts that move against each other. This creates a slippery surface that reduces friction and prevents the parts from wearing out quickly.
Protection from Dust: Machines are covered when not in use to prevent dust from settling on them, which helps keep the moving parts clean and reduces the need for frequent cleaning.
Weatherproofing: To protect against the effects of weather, metallic parts are often painted to prevent rust. Machines should also be stored in a dry place to avoid moisture buildup.
