Excerpt from John W. Rushton’s book, Effective Maintenance Management Using Planned and Preventive Maintenance.
PM work sheets are a vital part of an effective planned maintenance program, and they must be functional. The following tips can help you create more effective sheets:
- Before starting the preparation of the PM sheets, become as familiar as possible with the equipment and its systems. Each system should be estimated as to the percentage of emergency or expensive repairs that the system is responsible for. If the percentage is low, give that system a low priority.
- All items on the PM sheets must be completed every time. If the PM line people consistently fail to complete every item on the sheets, it is likely that the sheets need modification. The sheets must be dynamic, and changes should be made as necessary to encourage strict compliance.
- Each sheet should have space for the planner or foreman to enter minor repairs, and space for the craftsman to list needed repairs for backlog.
- PM sheets should be comprised of ITEMS (jobs) and SYSTEMS (closely related groups of jobs).
- Items should meet the following criteria:
- Must eliminate a significant source of downtime or expense.
- Can be reasonably completed during the normal PM time frame.
- Can be checked for compliance.
- Systems should meet the following criteria:
- Must eliminate a significant source of downtime or expense.
- Responsibility for the entire system can easily be assigned to a craftsman or group of craftsmen.
- When grouping items from a system on a PM sheet, each item should be listed in a logical order of completion.
- When designing system PM activities, always take into account the other PM or operating activities that may be taking place at the same time.
