I bought the trimmer in 2007. I'm having issues with the line not feeding automatically. I have to take it apart & pull the line out every time = not fun. I've used two sizes of line - green 0.080" & orange 0.095". The only difference is I don't have to stop the trimmer as often with the orange b/c it is thicker & stronger. Note that it's not wound wrong or too tight. The shaft gets hotter than what I think it should. Unfortunately, I don't have an IR gun to give exact temp though. It seems to have gotten worse. It's a angle head so I assume the gear there is getting too hot transmitting the heat to the line since it is sticky when I take it apart & pull it through. What lube should I use? Any other ideas? I'm afraid that I'm going to find the gears are ground to dust & need replacing. Just a cheap trimmer? It is Stihl's lowest trimmer. I have ~ 8 hours run time on it. Thanks.
