What is the first step in conducting a cold start of the main engine?

The initial stage of conducting a cold start of the main engine focuses on checking fluid levels. This step is crucial because ensuring that all fluids, such as oil, coolant, and fuel, are at the proper levels is essential for the engine's safe and efficient operation. If fluid levels are insufficient, it can lead to severe engine damage or failure during the start-up process.

By confirming that the fluid levels are adequate, you are taking necessary precautions to prevent issues that could arise from low lubrication or cooling capabilities as the engine begins to operate. This foundational check sets the stage for a successful engine start and helps identify any potential problems before further steps, like pre-lubricating or following the start-up checklist, are taken.
