Hook up air hose to main manifold and blow out all lines to conveyor spray and washdown hose reel.
Also to play it safe check water separator filter on engine to make sure there is no water in it. If so drain. Some of the mills have a manual shutoff for fuel tank. If it has one shut it off and tag the mill so anyone that gets on it knows it is shut off. There was one case where the water separator bowl froze and cracked and emptied a full tank of fuel on the ground slowly where it was not noticed for a while.
