御装置。[Scope of Claim for Utility Model Registration] In a control device for a hydraulic excavator that feedback-controls the boom, arm, and bucket of the front working system of a hydraulic power excavator using a single multi-joint operation lever, when the engine of the hydraulic excavator is started, stopped, or operated. A setting that provides a reference signal level for the signal level of the detector installed at each joint of the front work system, instead of the signal level of the transmitter installed at each joint of the multi-joint operating lever, when the person leaves the seat. In contrast to a normal control state in which the standard position of the front working system and the standard position of the multi-joint operation lever operate in almost the same way, the standard position of the front working system is A position shifter that allows you to manually shift the zero point position so that the input and output signals of each joint match the posture and the posture that makes it easy to operate the multi-joint operation lever, and the input of three joints that correspond to the working situation of the hydraulic excavator. A control device for a hydraulic excavator, comprising: a mode selector that arbitrarily adjusts the ratio between a signal amount and an output signal amount.
