The operational experience of service and repair devision is resulted. History of its development, the purpose and a problem of it are described. The main direction in service work is introduction of the new equipment, materials and service for the purpose of increase in a between-repairs cycle of the prime mission equipment and decrease in expenses for maintenance service and repair. Service maintenance, monitoring and equipment audit allow to define precisely enough a technical condition, dynamics of depresiation of units, to predict forthcoming repairs on time and volumes, to spend due preparation, to minimise expenses for maintenance service and repairs. Technically operative equipment not only solves industrial problems, but also promotes improvement of ecological aspects and decrease in risks in the field of a labour safety and industrial Safety.
