An excavator (10) has a quick coupler (24) coupled to the distal end (22) of its excavator arm (12). The quick coupler (24) can be operated from the cab (14) of the excavator (10), and is connected to a warning control system (48) or an instructional device (102). The warning control system (48) is connected to a coupler control circuit (46), which controls the coupler (24) and the system or circuit acquires information on the coupler's status. A control system activation warning circuit is then arranged to be responsible for issuing warning signals (53, 54) to personnel located external of the cab when the coupler control circuit (46) is activated into an accessory coupling procedure mode, or an accessory decoupling procedure mode. To do this, the warning circuit (48) is coupled to an audio and/or visual alarm (50, 52) for directing the warnings (53, 54) to the personnel, including bystanders. The instructional device, however, instructs the operator as to how to use the coupler.
