Abstract
A motor driven appliance comprises a battery, a motor, at least one switch, a control unit, an abnormality detection unit, a determination unit, and a processing unit. The at least one switch comprises an operation switch. The control unit controls driving of the motor by controlling power supply from the battery to the motor when the operation switch is turned on. The abnormality detection unit detects abnormality of the appliance. The determination unit determines whether the detected abnormality is a first type abnormality that can be cleared when the operation switch is switched from on to off, or is a second type abnormality that cannot be cleared even if the operation switch is merely switched from on to off. The processing unit is configured to perform a specific process when it is determined that the detected abnormality is the second type abnormality.
