The document provides instructions for starting and stopping a hydro machine. It lists pre-checks that must be completed before starting, such as ensuring intake gates and valves are open. It then outlines a 6-step starting sequence that involves opening valves, increasing guide vane position and speed, engaging the excitation system, synchronizing voltage and frequency, and increasing load. The 6-step stopping sequence reverses these steps, first decreasing load and disengaging systems before closing valves and applying brakes once the machine has come to a standstill.
