When the stacker is approaching the parking area and the speed of the vehicle is too high, how should it slow down?

When a stacker is approaching a parking area at a high speed, the most effective and immediate action to slow it down is to step on the brake with your right foot. This method allows for controlled and prompt deceleration, ensuring safety when maneuvering in potentially crowded or confined spaces like parking areas. Using the brakes is specifically designed for this purpose in vehicles, including forklifts, and it is the standard practice to reduce speed without putting additional mechanical stress on the vehicle.

Engaging the handbrake gradually, while it can contribute to slowing down, is typically more appropriate for securing the vehicle once it has come to a complete stop rather than serving as an immediate braking method. Shifting into a lower gear also aids in controlling speed but is more applicable for driving situations rather than simply reducing speed quickly during an approach. Letting go of the steering wheel is neither safe nor effective in reducing speed and could lead to loss of control.
