Operating a mode change switch changes the mode of a controller to first or third command control mode which is suitable for a work involving a large displacement of a manipulator or a second command control mode suitable for a work requiring precision. When an operation handle of an operation unit is operated, the controller controls the operation unit in each command control mode to drive the manipulator. In a case where a large-displacement-involving work and a precision-requiring work are continuously executed, therefore, the mode of the controller is first changed to the first or third command control mode by operating the mode change switch and then changed to the second command control mode. The manipulator can be driven in the proper command control mode for a work to be done.
