How do I make a preventive maintenance program?

First of all determine a starting point for your new maintenance program.
Begin by listing every piece of equipment and assign asset or identification numbers to each unit, then determine the health status of each piece of equipment, create a downtime log for each asset that is essential to overall business operation, make the log form simple enough that your machine operators will begin to capture the amount of downtime, finally create a service request sheet that allows operators to identify issues that may not increase downtime.
After creating the proper forms and procedures, your people need to make routine inspections, this will help you measure to see if employees are doing what they are supposed to do.
