Title:

CONSTRUCTION MACHINE MAINTENANCE DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/203989

Kind Code:

A1

Abstract:

A construction machine maintenance device comprises: a malfunction detection means for detecting a malfunction in an apparatus which is mounted upon a construction machine; a malfunction information output means for outputting the detected apparatus malfunction information; and a maintenance mode setting means for setting a maintenance mode for carrying out maintenance work upon the apparatus. If the malfunction in the apparatus is detected when the maintenance mode is set, the malfunction information output means either negates or does not output the malfunction information thereof. It is thus possible to reliably avoid outputting erroneous malfunction information arising with maintenance work by switching the construction machine to maintenance mode prior to the maintenance work.
