(1) Implement lockout solenoidImplement lockout solenoid (1) is controlled by the implement lockout switch on the right hand operator console. If solenoid (1) is not energized, oil will not be able to pass through the manifold. The combined flow of the implement charge pumps will flow over the main relief valve. If solenoid (1) is energized, oil is supplied to the downstream components. If solenoid (1) is energized, the implement charge pump oil divides within the combination valve. The oil circulates through three separate circuits. One circuit passes through the hand controls and the other two circuits pass through the winch motors. This oil ensures that the hand controls and the winch motors are responsive in cold weather.
