PROBLEM TO BE SOLVED: To provide an electric machinery tool, which can prevent an erroneous notification that the remaining battery power is low even when a battery voltage temporarily drops due to increasing operation for increasing a driving force generated by a motor while the motor is driving. ! SOLUTION: An electric machinery tool 1 sets a driving force of a motor M1 from "low" to "high" while the motor M1 is driving and prohibits displaying a notification on a display 7 until a prohibition time has elapsed even when a battery voltage is temporarily less than a first threshold and a second voltage threshold. !
