A big vehicle that resembles a steamroller, with a large roll on the rear end and a small roll on the front end, and spikes below the bottom, and a steaming chimeny, is rolling from left to right. Before it, a person with a trowel hectically tries to fix a pothole, with beads of sweat coming from his head. Another person's upper part of the body is showing in front of the front end, the rest of the body apparently squeezed under the front roll, he is raising his right hand and looging slightly agonized. Another person is inside the vehicle, shoveling coal into a stove. He looks snarls his teeth and beads of sweat are coming from his head. In a small room in the rear end, an angry-looking person working with a screwdriver, is shown. Subtitle: "Fully Automatic Installation"
