Abstract

A controller (102) of a construction machine (1) controls idle-stop control function so as not to interfere work and ensuring of safety. The controller (102) switches between enabled and disabled states of the idle-stop function in response to a selection switch (30) operated by a user, and when the idle-stop function is enabled, the controller (102) outputs a display on alarm/indicators (33, 34, 37, 38) inside and outside a vehicle. The controller (102) outputs an alarm to the alarm/indicator (33, 34, 37, 38) inside and outside the vehicle before the idle-stop control automatically stops an engine (101). Even before the engine (101), automatically stopped, is restarted, the controller (102) outputs an alarm to the alarm/indicators (33, 34, 37, 38) inside and outside the vehicle and does not restart the engine (101) unless a hydraulic circuit is locked by a lock lever (23).
