The starter is the component responsible for cranking the engine each time the pump is started. It uses an electric motor powered by the machine's battery to spin the engine flywheel fast enough for combustion to begin. On pump equipment like the APT4S and APT4T series, a properly functioning starter is essential for getting the unit running quickly in the field. When a starter fails — through worn brushes, a seized drive gear, or internal electrical failure — the engine will not crank at all, leaving the pump completely inoperable until the part is replaced.
