a)Condition-based Maintenance

“The preventive maintenance initiated as a result of knowledge of the condition of an item from routine or continuous monitoring.”

b) Running Maintenance

 “When the preventive Maintenance tasks (such as greasing, cleaning, and lubrication) are carried out while a machine is running, it is called running Maintenance.”
