What is the key factor to remember regarding the duration of each dry motoring attempt?

The key factor to remember regarding the duration of each dry motoring attempt is that it should not exceed 30 seconds. This limitation is crucial to prevent potential damage to the engine and to ensure that the components do not overheat or wear excessively during the motoring process. The 30-second duration is a standard practice that promotes safety and efficiency in engine checks, ensuring that there is enough time for the system to cool down if multiple attempts are needed.

Understanding this timeframe helps maintain equipment integrity and ensures proper functioning during operation. The other options suggest durations that either exceed safe limits or are not aligned with standard practices in motoring procedures. By adhering to the 30-second limit, operators can effectively manage engine health and performance during dry motoring attempts.
