Default PC 690 Shutting Down

I'm using a table mounted PC 690 to route 3/4 MDF into raised panels for wainscoting. I've done it before and had no problem, but today the router quit on me about 3/4 through the second panel. When I moved the panel away the bit spun slowly rather than remaining stopped. After checking all mountings, plugs, speed control setting, etc., I fired it up and it ran fine for one more panel before shutting off again.
Am I overloading it with too big a bite and engaging the thermal overload? It's a 2.2 inch horizontal bit so I'm running pretty slowly (as per recommendations in this forum). This has never happened to me before, using the same router, table, bit, etc., so I'm a bit confused.
Any advice?

It sounds like overload may be the case. If you are taking more than about 1/4" bite at a time, that's too much. I would suggest even less. Try a smaller bite and taking more than one pass.

Hi WallyB

Just a long shot are you using a speed control (after market one) ??

"bit spun slowly"


If so pull it out of line and then try it...

Another item to check is to see if your router is full of sawdust. After unplugging it try blowing some compressed air through it. This happens more than you would believe. It is also possible your brushes are wore out and need to be replaced, is this an older router?

I think curiousgeorge hit it. I backed off on the amount of bite and everything seems okay. I was trying to do the panel in two passes and now I'm doing four, but a little time is no biggie if it makes it work right.

On the other replies - I have the 690LRVS, so the speed control is a part of the router itself. I plan on installing an external switch for just on/off, but I'll stick with the integrated speed control. Mike, I see what you mean about sawdust. I've been vacuuming it out every time I pull it from the table to change a bit, but I'll take it outside and hit it with air tomorrow. It hasn't been run for many hours, so I don't think the brushes are an issue, yet.

Thanks everyone. Your quick responses are greatly appreciated.
