Hitachi M12V speed control bypass
I posted awhile back about problems I was having with the speed control on
my Hitachi M12v. Specifically, that it wouldn't hold the speed it was set at. Now the problem has gotten worse and it will slow down while in use until the collet stops completely (while the power switch is on). I can set it on the bench and 10,15, 20 seconds later, it will start up again (no it's not a regular habit of mine to not switch things off, I'm just giving an example). Anyway, since the speed control is obviously shot, I'm looking to remove it. I seem to remember that some others have done this from my previous post. Can you offer any advice? There are three wires into the speed control. One from the switch, one to the motor (I know what to do with these two) and then a yellow, thinner mystery wire. Any suggestions from folks who have done this before? Thanks, jc |

I called Hitachi. They (for some odd reason) neither recommend nor are
willing to offer any advice regarding rewiring any part of their router. Something about liability. Go figure. jc "Dave" wrote in message m... Call Hitachi They have an 800 number. |

Hitachi M12V speed control bypass
I did that on mine when the speed control went out. Don't remember
exactly what wires went where. As I recall the small yellow wire is a feedback wire into the controller and doesn't need to be hooked back up to anything. The wire from the switch goes directly to the wire from the motor. I just took to controller completely out and put a piece of tape over the hole. Works fine although I don't use it a whole lot. |

Interestingly enough, the speed control must have limited max revs because it *seems* to run faster now. Then again, that may be my imagination since it probably hasn't run at top speed since the electronics started going bad which was some time ago. Thanks again. Joe |
