The display redisplays a reduced camera image at a reduction scale of 60% according to an abnormality information signal. An open areaoutside the area displaying the camera image. The display control device displays a warning icon (large size), corresponding to abnormality information regarding a filter of a DPF device, in the open area. The operator recognizes the warning and immediately stops the operation, moves to a place where the filter regeneration is possible while checking the safety of the surroundings by viewing the camera image, and then carries out the filter regeneration.
