If I understand ppg’s explanation, it’s not tripping the breaker at the power source, it’s doing a thermal shutdown at the machine. It’s frustrating to explain because I run hundreds of feed of board through my DW733 in the Tucson summer heat without a problem.

I was wondering the same thing as papadan regarding airflow. When I turn my planer on, I leave it on for the duration of my planing operation. That keeps the air flowing through the motor. There’s no reason to turn it off to adjust the head, or anything. I’ve done a dozen door stiles, planing 80” boards from 8/4 down to 1-3/8”, in one session. The planer is running for an hour-plus, never turned off.

I’d recommend contacting DeWalt. That’s a quality planer. Much nicer than my DW733, so it shouldn’t do a thermal shutdown like that in normal conditions.
