A maintenance log records work performed on a piece of equipment. It should be kept for __________.

Maintaining a comprehensive maintenance log for every machine is essential in Total Productive Maintenance (TPM). This practice ensures a detailed record of work performed on all equipment, which is crucial for tracking performance, scheduling future maintenance, and identifying trends or issues over time.

By documenting maintenance activities for every machine, organizations can ensure that all equipment is regularly checked and maintained, which enhances reliability and operational efficiency. It allows for the analysis of machinery performance across all types of equipment, not just those deemed critical or used frequently, leading to proactive maintenance strategies that can prevent failures and extend the lifespan of all equipment within the facility.

Keeping a log for only critical machinery, heavy equipment, or machines used daily limits the scope of maintenance strategy and can leave less-used machinery vulnerable to unexpected breakdowns. Comprehensive logging for every machine fosters a culture of ownership, accountability, and thoroughness in maintenance practices across the entire organization.
