Abstract: A terminal device includes a processor and a display. The processor causes the display to display a portion of a plurality of portions of a work machine which is a candidate inferred to be a cause of a failure of the work machine. The processor further causes the display to display a video or a plurality of images showing a disassembly procedure for disassembling the work machine until the portion that is the candidate is exposed.

Abstract: A work vehicle includes a plurality of hybrid instruments, a cooling medium circuit, a radiator, a fan, a variable mechanism, a plurality of sensors, and a fan control unit. The cooling medium circuit communicates with the plurality of hybrid instruments to cause a cooling medium for cooling the plurality of hybrid instruments to circulate through the hybrid instruments. The radiator is connected to the cooling medium circuit. The fan generates cooling wind for cooling the radiator. The variable mechanism is capable of changing the number of rotations of the fan. The plurality of sensors are provided in correspondence with the plurality of hybrid instruments, respectively, each detecting the temperature of a corresponding one of the hybrid instruments. The fan control unit controls the variable mechanism based on the temperatures detected by the plurality of sensors, to control the number of rotations of the fan.
