I brought the new 1618EVS to the job and after routing D pine for all togeather maybe 3 hrs. (NOT continuous running time) I smoked the motor.  After a long conversation with the authorized tool service center I sent it in for a complete motor rebuild.  They assured me it would come back assembled to tighter specs. than what it was manufactured at.  I was skeptical that it would be returned to me in any decent workable condition yet two years later I'm still milling trim with it.  However I'm still waiting for that day, in the middle of some job, where it will start spewing smoke out of the motor housing again.
