My job: Sanding of visible roof beams. I was initially unsure whether a lighter machine for this purpose would be more suitable. Am now but very happy after work and had decided correctly. * With the sanding belt width of 100 mm is canted not easy and carries more evenly. Overall, the machine is very good in the hand (middle-strong men's hands, who work more in the office than at the construction site) * The engine is very strong and the machine is not easy to hot even with heavy, prolonged use. * The removal rate is very good, depending on the abrasive belt, but it's also quite fine. Of course, a disc sander is more suitable for very fine grinding. * The change of sanding belts is absolutely simple, the lever acts robust and is easy to grip. * The track setting of the sanding belt is simple and works very reliably. With proper use, the tape does not extend laterally. * You can grind up to the edge on the right side, if you set the course of the sanding belt accordingly. * The speed can be adjusted well (though sounds the machine at low speed a bit strange) * I have an external dust extraction used (Milka-sucker with fine filter). The dust bag is in my view, generally only a temporary solution. It also falls so even enough to dust. * The machine is very well made and sturdy. * Has been able to find anything negative. Conclusion: Would not the machine for sale again
