Autonomous maintenance is the concept that change the culture of operators calling technician all issue related to machines. AM should be carried out by the operators of the machines rather than by dedicated maintenance technicians. It is a core concept of TPM which gives more responsibility and authority to the operators and releases the technical personnel to do more PM and improvement works.
In a traditional way, the operators run the machines until they break or reach the time for maintenance, they will hand them to the maintenance team. AM has the operators performing the simpler and safer maintenance routines such as lubrication, bolt tightening, cleaning and also inspection.
