Abstract
A work machine includes a mechanical arm and a hydraulic actuator coupled to the mechanical arm to move the arm between a first position and a second position. A valve is in fluid communication with the hydraulic actuator for supplying fluid to the hydraulic actuator. A pump is configured to discharge fluid to the valve. An engine is operatively connected to the pump. A coolant system is in thermal communication with the engine and includes a temperature sensor. A controller is in communication with the pump and the temperature sensor. The controller is configured to transmit a control signal to the pump to modify a flowrate of the pump and to adjust the flowrate of the pump in response to a signal from the temperature sensor that a temperature is at or above a set temperature value.
