    Can't answer that question because I'm not Chinese.!! . . . But that spindle you have there isn't 9Kw. It's a 2.2Kw and whether 9Kw or not they still have a duty cycle and these cheaper units won't cut 10hrs continuously for long before they start feeling the effects. I also very much doubt they will be rated S1 so can cut continous.
