Hello, I have developed a problem with my trimmer (FC-20A) as well. It will work for a while then the blade will stop, slightly past the cut and shut down the whole machine. I have been checking the sensors, connections, I have even removed the knife and it'll still stop. I did notice a lot of play (slack) in the chain. The Horizon SPF10 booklet maker and FC 10 Trimmer.
