I had already removed its predecessor and so many square meters and hours in speiss laid tiles, concrete foundations small hammered etc. When the coals were ground off the engine, I have unfortunately continued to work short and burnt by the sparked the collector. A Autausch of coals (in Varo ordered) then brought nothing, because the collector had become rough.
Now for POWX1155. Am convinced by this model. Even some old foundations, small walls removed. The hammer drill has power without end, because rather get the Meisel broken as the engine. Can recommend 1155, but pay attention to the wear on the coals. Last, but once it sparks, switch off and switch.
