To provide a wireless remote-control model capable of securing the safety of an operator (a user) as well as the safety of the wireless remote-control model itself.

A wireless remote-control model includes a safety management part 312 mounted in a central control unit 3 and having a determining part 314. The determining part 314 feeds a first pattern buzzer signal command indicating that the battery is connected to a buzzer control part 313 if a battery 27 is correctly connected, feeds a second pattern buzzer signal command indicating the start operation to the buzzer control part 313 in a checking period in which a start button is pressed while the battery is correctly connected, and feeds a third pattern buzzer signal command to notify the buzzer control part 313 that a power motor 7 is in the stand-by state in which the power motor can be driven if it is determined that the wireless remote-control model is normal as the result of the checking.
