If not, disassemble it carefully. It sounds like a broken part. I'm guessing that the plastic spline has broken. It is readily and cheaply replaceable.Sun, 25 Oct 2009 19:36:15 GMTsandyhttp://messageboard.dremel.com/Topic6111-28-1.aspxThe on/off switch of this rotary tool seems to be frozen in the off position. Tried WD40 but no luck. Any suggestions? Thanks.Sun, 25 Oct 2009 16:33:58 GMTPeanut
