The utility model provides a handheld type operating machine which can improve operating efficiency by improving operability of an output adjusting mechanism. An adjusting operating component (141) of the output adjusting mechanism (140) is arranged between a first throttle lever (120) and a handheld portion (111), a knob (141a) of the adjusting operating component (141) is arranged to be capable of moving freely in a preset scope, and by moving the knob (141a) from one end of the preset scope to the other end of the preset scope, output of an engine (3) can be adjusted from an idling running state to a highest output state. Therefore, by utilizing one-step operation of the knob (141a) of the adjusting operating component (141), the output of the engine (3) can be adjusted arbitrarily, and the operation on the output adjusting mechanism (140) can be realized in a short period.
