<p>The purpose of the present invention is to smoothly conduct maintenance work on a heat exchanger without the need to crawl under the machine body to work when draining coolant from the heat exchanger. A side of an engine compartment (75) can be opened and closed by means of a side cover (90) of the engine compartment (75), and a radiator (61) has a drain port (69) for draining the coolant. One end of a drain hose (71) is connected to the drain port (69), and the other end of the drain hose (71) can be pulled outside of the engine compartment (75) by opening the side cover (90).</p> |
