Abstract
A monitoring apparatus for a construction machine having an engine includes sensors for detecting abnormality conditions at various predetermined inspection positions. A warning system, cooperating with the sensors, provides an engine idling signal and a visual display in accordance with the detected abnormality condition. A delay circuit causes the warning system to activate the visual display only if the abnormality condition continues for a predetermined time after issuance of the engine idling signal. The engine idling signal itself is provided without delay upon detection of the abnormality condition, and causes the engine to idle.
