A controller controls a first FET to go on and off based on an input signal of a trigger switch and a push switch and controls a second FET to go on and off based on an input signal of a trigger switch, a push switch, and a operation detection switch. The controller then controls the time that the first FET is on for to be longer than the time the second FET is on for.
