■ As shown in the photos. Hitachi Cutter Psy-4 (110mm) ※ Operation confirmed · The switch turns on and it rotates. · The switch can be locked. · The depth adjustment plate moves. · I tried cutting a concrete block (photos included). That's all. ※ Blade wear is unknown, and the water injection cock's usability is unknown. 【Disclaimer】I believe it can still be used sufficiently, but it is an old, used, second-hand item. Please purchase if you understand the explanation, are familiar with machinery, or are accustomed to using it. Please refrain from purchasing if you are inexperienced or overly concerned about details.
