Autonomous Maintenance

The pillar that lets operators care for their own equipment — the heart of TPM.

This pillar changes the operator’s role from running the machine to looking after it. It starts with an initial deep clean, which is really an inspection: the first time someone puts their hands over the whole machine, they find the loose bolts, the weeping seals and the wear nobody had noticed.

From there it follows CLAIR — cleaning, lubrication, adjustment, inspection and minor repair — alongside eliminating the sources of contamination and the hard-to-reach points, so that cleaning does not become a permanent chore. Maintenance takes part as a coach teaching the work, not as an inspector looking for fault.

What this step covers

• Building in the operator a sense of owning his own machine
• The thinking behind TPM, why it matters, and the shape of the work
• Cleaning, lubrication, adjusting, inspecting and basic repair — CLAIR
• 5S and its application
• Small-group activity to improve the machines — the equipment improvement team
• Working with the maintenance department to raise production efficiency — the cross-functional team

What you receive

Machine in-depth observation, understanding of machine structure and working principle, ability to protect one’s own equipment, teamwork skills

• An in-depth survey of the operator’s own machine
• An understanding of the machine’s structure and how it works
• The ability to protect and look after his own machine
• Skill in working as a team

What autonomous maintenance actually means

The term carries two meanings. The first is preventing your own machine from failing: daily checks, lubrication, small adjustments and the minor repairs an operator can make. The second is deepening the operator’s competence with that particular machine — and this is the one most plants overlook.

The reason this work belongs to the operator rather than to maintenance is simple: nobody spends as long with the machine, nobody hears the change in its sound sooner, and nobody suffers more when it stops. A technician passes the machine once a day. The operator is with it for the whole shift.

Four capabilities have to be built: seeing an abnormality, inspecting against a standard, correcting small faults unaided, and understanding enough to know what must be handed to a technician. That last one matters as much as the first — repairing beyond your competence does more damage than not repairing at all.

How to apply it on the floor

1. Start with one or two critical machines
2. Give operators time for CLAIR inside the shift, not after hours
3. Audit each step before allowing the next
4. Have maintenance coach rather than police it

The mistakes we see most

• Reducing AM to a cleaning exercise
• Skipping steps to hit a management deadline
• Never attacking the contamination source, so cleaning repeats forever
