When conducting an operational inspection, how should the aerial device be rotated?

The aerial device should be rotated while fully retracted or extended to ensure that it operates effectively across its entire range of motion. This practice allows the operator to check for any obstructions and to confirm that the device's rotation mechanism functions smoothly without interference from other components or surroundings.

By rotating the aerial device in both positions, the operator can identify potential issues such as binding or unusual sounds that might indicate maintenance needs. Conducting the rotation while the device is retracted helps to minimize risk during the inspection, allowing the operator to observe all accessible areas and components without the complications of being fully extended, which could limit mobility or vision.

It's also important to note that rotating the device only when fully extended or only from the ground would not allow for a comprehensive operational inspection, as both scenarios could obscure the checking of critical components that would be visible in the other positions. Therefore, the best practice is to perform the rotation in both retracted and extended states to ensure thorough and safe operational assessment.
