Before changing the direction of travel of the stacker, what should it do?

Before changing the direction of travel of the stacker, it is essential for the stacker to stop completely. This practice ensures that the operator has full control of the equipment and can assess the surrounding environment before moving again. Stopping prevents unintentional movement that could lead to accidents, collisions, or tipping of the load. A full stop allows the operator to take in their surroundings, ensuring awareness of any obstacles or personnel nearby.

Though other options may seem relevant, they do not prioritize the most crucial safety step, which is to bring the stacker to a complete halt. By doing so, the operator can avoid potential hazards associated with improper direction changes while the vehicle is still in motion.
