I just got my new Magna Matic 9000 Sharpening Station and assembled it this morning.. While using it on my second blade the motor shut off.. it over heated. I had to wait 10 mins... It came back to life for approx 12 minutes and shut off again. same cycle over and over again! I changed extension cords.. ( both are 16 gauge.. 1st was 75 feet and second was 50 feet ) I went and purchase a fan to blow directly on it while in operation.. No change. Still overheated. Has anyone experienced this? Should I go to a 14 gauge or 12 gauge cord? I really like the cut/angle, but... Whiskey tango Foxtrot.
