Maintain an asset history that includes initial purchase details, warranty status, and a log of all repairs or component replacements. Use standardized forms or digital logging tools to facilitate consistent data entry and enable efficient audits. Periodically review maintenance logs to identify recurring issues, track part lifespans, and plan for proactive replacements before failures occur. Ensure backups of digital records and implement secure access controls to safeguard sensitive information while allowing authorized personnel to retrieve historical maintenance data.
