Preventive maintenance works best when it is specific to the equipment, operating conditions, and consequences of failure. Start with the assets that affect safety, production, product quality, or energy use.

For each asset, record what must be inspected, how often it should be checked, the acceptable operating range, and who owns the follow-up. Include simple observations such as unusual noise, heat, vibration, leakage, or repeated alarms alongside instrument readings.

Keep the record useful. A short service note should show the condition found, work completed, parts used, and the next action. Over time, those notes reveal recurring faults and help your team decide where monitoring, redesign, or replacement will produce the strongest result.
