During a pre-operation check, what should be inspected on a stacker?

During a pre-operation check on a stacker, it is crucial to inspect the functionality of the steering controls. This is essential for ensuring the operator's safety and the safe operation of the equipment. Properly functioning steering controls allow the operator to maneuver the stacker effectively, maintaining control while navigating crowded or tight spaces within a work environment. If the steering controls are not functioning correctly, it can lead to accidents, reduced efficiency, and can endanger both the operator and bystanders.

Other options, while they may involve aspects of the stacker's operation or the use environment, do not directly address critical operational safety aspects. For example, checking the color of the stacker does not contribute to its operational integrity, inspecting the operator's personal items does not impact the functionality of the equipment, and assessing the stacker's weight is less relevant compared to ensuring that all operational controls and safety systems are in place. Prioritizing the function of steering controls ensures that the stacker can be operated safely and efficiently.
