I remember stihl took that same approach when the 600 came out and it was breaking from hanging. Fact was they built a thin housing to reduce the weight. I just had shindawaw hedge trimmer with articulting blades and the housing broke. They covered it while in fact it was likely due to being transported in a rack.
