Erststart

Erststart is a German term referring to the first start-up of a machine, system, or device after installation, shipment, or repair. It denotes the initial activation and setup phase preceding normal operation. The goal is to verify proper installation, ensure safety, and initialize components such as engines, electrical systems, sensors, and software.

In mechanical engineering and automotive contexts, Erststart describes the first engine start after assembly or overhaul. It typically involves preparatory checks (fluids, connections, lubrication), a controlled power-up, and a staged ramp from idle to operating speed, with monitoring of temperatures, pressures, leaks, and unusual noises. The process may require supervision and a documented sign-off and is sometimes followed by an Einfahr- or break-in period to facilitate wear-in and seating of components.

In software and electronics, Erststart may refer to the initial boot or commissioning of new hardware or embedded systems. This includes license activation, calibration of sensors, firmware initialization, and the loading of configuration data. A gradual startup can be recommended to verify interfaces and to allow self-tests to complete.

Documentation for Erststart often provides a checklists and safety notes; deviations are recorded, and corrective actions are taken before mass operation. The term is used in German-language manuals and industry materials to distinguish the first start from routine starts.

Etymology and usage: Erststart combines Erst (first) and Start (start). It is widely used to describe the inaugural startup in automotive, mechanical engineering, and IT contexts and is related to terms such as Erstinbetriebnahme, Einfahren, and Anlauf.
