WORK MACHINE DISPLAY SYSTEM

Provided herein is a display system for a working machine capable of displaying warning information while also displaying a high-quality camera image. A display control device 53 redisplays a reduced camera image 33b2 at a reduction scale of 60% according to an abnormality information signal. An open area 44 occurs in part of a camera image area 42 outside the area displaying the camera image 33b2. The display control device 53 further displays a warning icon 34b (large size), corresponding to abnormality information regarding a filter of a DPF device 13, in the open area 44. The operator recognizing the warning icon 34b immediately stops the operation, moves the hydraulic shovel to a place where the filter regeneration is possible while checking the safety of the surroundings by viewing the camera image 33b2, and then carries out the filter regeneration. After finishing the regeneration, the operator confirms that the warning icon 34b has disappeared, moves the hydraulic shovel to the site of the operation while checking the safety of the surroundings by viewing a camera image 33a (for normal times), and then restarts the operation.
