What is the purpose of the joystick lockout rocker switch in the off position?

The joystick lockout rocker switch in the off position is designed to prevent hydraulic fluid flow to the joystick. This safety feature ensures that the joystick controls remain inactive and prevents any unintended movement of the crane's functions when the operator is not ready to use them. By keeping the hydraulic fluid from reaching the joystick, it effectively locks out any operations that could lead to potential hazards or accidents, giving the operator peace of mind when the crane is not in active use or during maintenance checks. The other options pertain to different functions that do not align with the specific role of the joystick lockout rocker switch, which is solely focused on maintaining safety by controlling fluid flow.
