1.When the ladder is lowered, the ladder limit switch is turned ON, the swing pilot shut-off solenoid valve relay circuit is grounded, turning the swing pilot shut-off solenoid valve relay ON.
2. In addition, when either the engine stop switch or the emergency engine stop switch (in the cab) is depressed, the swing pilot shut-off solenoid valve relay circuit is grounded, turning the swing pilot shut-off solenoid valve relay ON.
3. Then, current from fuse terminal #21 magnetizes the swing pilot shut-off solenoid valve via the swing pilot shut-off solenoid valve relay.
4. As the circuit between the swing pilot valve and the control valve is closed by the swing pilot shut-off solenoid valve, the swing function is inoperable.
