During an operational check, what is important to remember about the aerial device?

The focus during an operational check of the aerial device is to ensure that it functions as intended in both extended and retracted positions. Rotating the device while it is fully extended or fully retracted is vital for verifying that all moving components operate correctly and safely. This practice helps identify any mechanical issues such as binding, excessive wear, or misalignment, which could pose risks during actual firefighting operations.

By checking the rotation in both positions, operators can confirm that the aerial device is capable of pivoting smoothly, which is crucial for positioning the apparatus effectively in various operational scenarios. Ensuring the device operates correctly in all positions ultimately enhances safety and efficiency when the equipment is deployed in emergency situations.

The other options do not cover the necessary aspects of a comprehensive operational check. For example, checking only while extended overlooks potential issues when the device is retracted, while keeping the device stationary does not account for functionality where movement is required for effective service. Lastly, performing checks during low wind conditions is more about safety during testing, but does not ensure the full operational capabilities are tested across different scenarios.
