Problems with PC 7424XP

[sunday joe]

Thanks for all of the suggestion from everyone. I finally took mine to the repair show and I am waiting to hear back and what they tell me.

I confirmed that my heavy duty extension cord does meet the requirements from PC. I tried using the unit again yesterday and it started knocking and puked grease all over the backing plate and hood of the car I was polishing.

Let us know how the repair turned out. All things mechanical eventually break down. Some sooner than later. Is it covered under warranty ?
