8.2. Understanding Preventive Maintenance
We get the oil changed in our cars so the engine doesn't blow up. We go to the dentist to make sure our teeth don't fall out. We buy life insurance, just in case.

We do them because we know what the consequences could be if we didn't.

It can make our machines run longer and faster, which is good for everyone involved. This section outlines some preventive maintenance ideas, tools, and procedures.
