Stihl FSE 52

Poor design – Beware, the trimmer head of this model is poorly designed, and even worse it cannot be removed/replaced. I got sick of endlessly having to stop work due to constantly losing the line feed due to the unreliable 'bump' mechanism so bought a replacement 'unbreakable' head that had good reviews. Unfortunately the design of my FSE 52 doesn't allow the head to be removed. According to the manual, some FSE 52s have a separate fanwheel and the head is replaceable. Other types, like mine, have an all in one fanwheel/head that can't be removed. Wish the dealer had mentioned this...
