What is maintenance?

Maintenance is the work that is done to keep something in good condition. It can include things like checking for damage, fixing problems, and cleaning. Maintenance can be done on a variety of things, such as buildings, cars, and machines.

There are two main types of maintenance: preventive maintenance and corrective maintenance. Preventive maintenance is done to prevent problems from happening in the first place. It can include things like changing oil, checking brakes, and cleaning filters. Corrective maintenance is done to fix problems that have already happened. It can include things like replacing parts, repairing leaks, and welding cracks.

Maintenance is important because it can help to extend the life of a product and prevent it from breaking down. It can also help to improve the safety and efficiency of a product.
