摘要： A construction machine includes a measurement unit, a storage unit, and a notification unit. The measurement unit measures the number of times of drive of a starter. The storage unit stores the number of times of drive measured by the measurement unit and a reference value. The notification unit executes a notification process for providing notification of the drive status of the starter on the basis of the number of times of drive and the reference value. Preferably, the construction machine further comprises a comparison unit that compares the number of times of drive and the reference value. Preferably, the notification unit provides, in the notification process, notification of the result of the comparison by the comparison unit.

摘要： A work vehicle includes a drive unit, a fan motor, a fan configured to be driven by the fan motor, an overrun state detecting unit configured to detect an overrun state of the drive unit, and a control unit. The control unit is configured to control a rotational speed of the fan to reach a first fan rotational speed by increasing the rotational speed of the fan when a detection value detected by the overrun state detecting unit becomes greater than or equal to a first threshold. The control unit is configured to control the rotational speed of the fan to reach a second fan rotational speed higher than the first fan rotational speed when the detection value becomes greater than or equal to a second threshold greater than the first threshold.
