This year, we purchased 3 Echo SRM-230 models because of their light weight use and for light duty line-trimming. The other day our two helpers came to the trailer after doing a large job and were complaining of forearm burns from the machines. We opened the first aid kits and applied the usual burn creams, and bandaged them up and off to work we went. The next morning, those spots had water blistered up and became infected on one man. I used one of the units myself that day and for the first time of our career that the units do--in fact--get hot as hell on the clutch area and the metal casing. We have used Echo line-trimmers before and now use the Stihl models continuously. Has anyone else been having these issues with their units. I have been line-trimming for over a decade and have never had these kind of burn since the old time when the muffler covers were metal and not plastic. The old JD line trimmers were bad about burning the stew out of you! If so, what means have you done to eliminate the problem from hurting your employees. This is a serious problem as the guys are real pro's at using the line trimmer correctly, but occasionally you do have to rest the thing when it gets hot!!--The heat outside-I mean!! I burned the crap out of my arm and it blistered up too!!!!!!! Are you Echo reps out ther looking at my thread??? Give me some feedback!
