What should you do if you notice that there is no water in the water tank of the stacker?

When you notice that there is no water in the water tank of the stacker, stopping and turning off the engine before adding water is the appropriate action. This is essential to prevent potential overheating of the engine and subsequent damage. Running the machinery without sufficient water can lead to serious operational issues, impacting both the performance of the stacker and its longevity.

By turning off the engine, you eliminate the risk of causing further damage as the engine cools down. Once the engine is off, you can safely add water to the tank, ensuring that the stacker is ready for operation again without any risks associated with overheating. This method follows safe operational practices and helps maintain the equipment's efficiency.

In contrast, continuing to work without addressing the lack of water could lead to severe mechanical failure, while simply informing a supervisor or letting it cool down without immediate action does not address the urgent need to replenish the water for safe equipment operation.
