    Hyundai Robex 450LC-7A Excavator warning lights

    My Hyundai excavator has a check engine light and another warning light on the console that I can’t figure out. I don’t have an owners manual and can’t find anywhere online that tells me what this symbol means. Has anyone run into this service light before?
