Service equipment before small problems become production stops.
Preventive maintenance uses planned inspections, lubrication, cleaning, adjustment, replacement, and condition checks to reduce unexpected equipment failures. Effective programs balance maintenance effort with asset criticality, failure patterns, and production risk.
Design the plant around movement, capacity, and reliable execution.
Equipment placement, material travel, work queues, schedule changes, maintenance access, and production feedback all influence how smoothly a factory operates.
Reduce the hidden friction between production activities.
Unnecessary travel, unclear priorities, poorly placed storage, reactive maintenance, and unbalanced work can all consume capacity without appearing as direct machine cycle time.
CRIT-AAsset Criticality
Maintenance frequency should reflect the production consequence of failure, redundancy, repair time, safety impact, and known failure modes.
CRIT-BTask Quality
A maintenance task should specify what to inspect, acceptable condition, tools, parts, lubrication, torque, cleaning, and verification after service.
CRIT-CCondition Feedback
Vibration, temperature, pressure, wear, current, cycle count, and operator observations can help refine maintenance timing.
CRIT-DPlanned Downtime
Maintenance windows should coordinate with production schedules so service work protects reliability without creating unnecessary disruption.
Visualize the operating pattern before changing the system.
These diagrams focus on plant-level behavior such as travel distance, queues, capacity loading, schedule sequencing, and maintenance risk.
Maintenance cycle.
Inspection, service, verification, and feedback should repeat as a controlled reliability loop rather than as isolated tasks.
Failure risk.
Condition and failure risk often increase gradually, giving maintenance teams an opportunity to act before the equipment stops unexpectedly.
Relevant plant and production resources.
External references are selected from the approved TempoJS manufacturing link inventory and matched directly to the operating topic.
Preventive maintenance should reduce production risk, not simply create more scheduled tasks. Asset criticality, failure modes, task quality, condition feedback, spare parts, and planned downtime determine whether reliability actually improves.
