  In this example, the leg part 3 including the indicator light 2 is removable from the portable fire pump main body 1. In some cases, the upper leg arm 3b and the indicator lamp 2 may be removable from the portable fire pump main body 1. With the removal of the indicator lamp 2, the cord 18 that supplies power to the indicator lamp 2 from the operation panel 9 can be disconnected from the connector 20 of the operation panel 9 at the base end.

  Further, in this example, there is one indicator light 2, and at least a fuel remaining amount sensor 5 that detects a decrease in fuel in the fuel tank 4 and an oil remaining amount sensor 8 that detects a decrease in oil in the lubricating oil tank 7. When one of the detection operations is performed, the vacuum pump 14 does not absorb water for a certain period of time when the overheat sensor 12 that detects overheating of the engine 6 due to a decrease in cooling water that is cooling the engine 6 performs the detection operation. When the water detection sensor 15 performs the detection operation, the display state is changed to perform display. In this case, the indicator lamp 2 is displayed when, for example, at least one of the remaining fuel sensor 5 and the remaining oil sensor 8 performs a detection operation, for example, blinks at a frequency of 1 Hz, and when the overheat sensor 12 performs a detection operation. The light is flashed at a frequency of 10 Hz, and when the water detection sensor 15 detects that the vacuum pump 14 does not absorb water for a certain period of time, the light is continuously turned off.

  Alternatively, the number of the indicator lamps 2 is one, and at least one of the fuel remaining amount sensor 5 for detecting the fuel decrease in the fuel tank 4 and the oil remaining amount sensor 8 for detecting the oil decrease in the lubricating oil tank 7 is detected. When the operation is performed, when the overheat sensor 12 that detects the overheating of the engine 6 due to the decrease in the cooling water that is cooling the engine 6 performs the detection operation, the vacuum pump 14 does not absorb water for a certain period of time.
