Thanks Whisper, you answered better than the sales person! We weren't sure. I wrote on Kymco USA and filled in the questioneer and included a paragraph describing the hammer drill sound and action. Well, I type it all out, sent it and it was taking a good while than all of a sudden a white screen popped up reading the web-site could not be found. I am just not having any luck or gain from this purchase yet!! I don't know, sales don't know, service don't know, Kymco Rep. don't know, E-Mail didn't go......don't want to say what I am thinking......
