Abstract
A cold planer machine may include a frame, a ground engaging member, a retracting vertical actuator system to raise and lower the frame, and a housing. The housing includes a vertical wall movable relative to the frame and a position detector to determine a relative vertical distance between the vertical wall and the frame. A drum in the housing is connected to the frame and rotates about a drum axis to plane the road surface. A spray bank disposed inside the housing is arranged to spray a fluid at the drum. A controller is configured to actuate fluid spray via the spray bank based at least in part on determining that the relative vertical distance is above a first threshold height value.
