TABLE OF CONTENTS Once the preventive maintenance tasks have been detailed, the next step is to determine the skills that will be required to perform the tasks. There are four main groups that will be responsible for performing the preventive maintenance tasks. They are listed in Figure 6-1.
Operator-based preventive maintenance tasks are generally related to the following activities:
Taking operating readings
Performing "sensory" inspections of the equipment
Performing minor adjustments or service to the equipment
In most organizations, the operator-performed preventive maintenance tasks will make up anywhere from 10-40% of the overall preventive maintenance program. There are some companies where the operator and maintenance technicians have a shared role; in these cases, the per centage can be greater. However, for this model to be successful, the company will invest heavily in technical training, raising the technical skills of operators to at least an apprentice level. (This model will be discussed in detail in Volume 6 of the maintenance strategy series.)
Operators of the equipment are usually required to make operational checks of the equipment while it is running. These checks usually involve recording data over various process parameters. These will include temperature, flows, quality information, tolerances, etc. This process provides an opportunity to have them also record any information that will add value to the maintenance of the equipment, for example:
Lubrication system flows and pressures
Hydraulic system flows and pressures
System temperatures
All of these parameters are important when determining if the equipment...
