Have the model for some time now the holder of the coal is broken in the engine, a tiny plastic piece the size of a 5 cent piece and probably a similar cost. As the saying goes, unfortunately, not an isolated case, is in another review here on Amazon at a different "size" of this model also occurred. As in that assessment, the only idea of Bosch Services is an engine change ... and it's about a small, cheap, demountable part - pathetic as it gets. Until then, the engine has a strong impression that the processing of the case, however, is weak, the plastic made thin, looks cheap and unstable. Light is the device - just at the expense of soundness, a bad design as a whole. I will then probably reach for a new lawn mower, Bosch is not it safe again.
