An engine-powered tool 1 includes a starter motor 106 to be driven by electric power supplied from a battery 80 to start an engine, start control means 102 to be driven by electric power from the battery 80 to control rotation of the starter motor 106, and a switching element (FET) 121 provided in series to a power supply circuit from the battery 80 to the starter motor 106, opening and closing of the switching element being controlled by the start control means. When starting the starter motor 106, PWM control is performed on the switching element and soft start in which a duty ratio is gradually increased is performed. The start control means 102 monitors temperature and battery voltage, and changes a ratio and time for increasing the duty ratio in the PWM control in accordance with the temperature and the voltage.
