When the stacker changes its driving direction, what must be paid attention to in the operation program?

In the operation of stackers, it is crucial to wait until the stacker is completely stopped before moving the hydraulic gear lever. This ensures that the operator maintains control and prevents accidental movements that could lead to unsafe situations or loss of load stability. When the stacker is still in motion, manipulating the hydraulic gear lever can result in unexpected changes in direction, speed, or even tipping over, especially if the load is raised.

Maintaining complete stop conditions allows the hydraulic system to engage smoothly and safely, ensuring the stacker is stable before initiating any direction change. This practice is essential for the safety of both the operator and any nearby personnel, as well as for the integrity of the load being handled.

Other options, while relevant to operational safety in general, do not directly address the critical aspect of safely changing direction within this specific scenario. For instance, checking tire pressure is an important maintenance task but not specifically related to the immediate maneuver of changing direction.
