The operation of this machine is really fun. The engine is powerful and the removal with good abrasive belts enormously. The belt runs well centered, and the change goes smoothly by hand. For longer works you have to be aware that such a machine for work in the vertical or upside down is quite difficult but, well and "goes to the arms." The noise pollution is kept within reasonable limits to what one would expect with such a machine. Due to the high Abrtag the Staubgangbox is very fast. Here is recommended especially with coarser grain suction. The mounting means Stationärset is well resolved, although I did not use this the attached ferrules, as they are a bit awkward to use (longer). The stop is very useful to a drawback: It can not be accurately set 90 °, but rather 92 °. Here I will rectify itself. Except for this little thing the device to the set's but worth every Euro.
