I just bought a 223L today and I have the same problem. I too would like a better answer than, It's not an arm rest. It's not a matter of resting your forearm on the top of the motor. The forearm naturally come in contact with the exhaust as you move the trimmer back and forth and up and down. In the mean time, I going to try wearing an arm guard of some sorts like they use for sports...here's hoping it doesn't melt. On second thought, maybe I'll duct-tape a hot pad to my arm instead.
