I got the DW618PK 3 base kit 2 or 3 years ago when Mark at HDT had a few for ~$120, a fantastic deal.
90% of my routing I do with the Bosch 1613 in the router table. I doubt if the Dewalt has 3 hours run time, all hand held, heck it's never been dusty!
I started routing a few mortises this afternoon and it ran for about a minute and I saw a brush arc and it stopped.
I removed the top cap and removed the brushes, finding the commutator very black (dirty). I cleaned it with crocus cloth. The brushes had deep horizontal grooves across the curved faces???
I sanded the brushes flat and removed the grooves and reassembled.
It made a couple of weak attempts to start but no jot.
I removed the cap again and noticed that the commutator is about 1/8" bigger below the brush area than where the brushes ride!
How the heck could the commutator wear that much in so little use? Until today I haven't seen any brush arcing and I'm attentive to that having worked with motors a lot in industry way back.
Anywhoo, it's probably out of warranty but I'll contact Dewalt Monday and see what they say about the commutator wear.
Makes me sick, I really enjoy using that router and got a super deal from Mark.
Thanks for the shoulders to cry on.
