Tackling Training Textbook KOMATSU Komatsu Training Center, 10th Edition, Published in Heisei 31 (2019) Special Education Skill Training Examination Certification License Certificate Factory Industry Construction Architecture How about for preparation, review, re-education, and checking important matters? I obtained this two years ago, and I believe there haven't been any changes to the content since then. Because unauthorized reproduction and use of the content and images of this textbook are prohibited, I cannot post photos, but I have underlined the parts that were said to be on the exam in red. I was underlining in red while fighting off sleep, so some of the red lines are wavy and messy. Thank you for your consideration.
