A work machine comprising:
- an engine;
- a fluid path via which a fuel oil is supplied to the engine;
- a first filter provided in the fluid path;
- a pump provided between the engine and the first filter in the fluid path to suck and output the fuel oil;
- a second filter provided between the engine and the pump in the fluid path;
- and
- a third filter provided between the engine and the second filter in the fluid path,
- wherein the second filter and the third filter are filters of filtration type to remove particulates included in the fuel oil,
- wherein the third filter has a filtration fineness higher than a filtration fineness of the second filter and has a filtration area larger than a filtration area of the second filter,
- wherein the first filter removes water included in the fuel oil, and
- wherein the second filter separates, from the fuel oil, the water remaining in the fuel oil after filtration by the first filter and includes a water detection sensor to detect the water separated from the fuel oil.
