I received the above belt sander and was pleased upon its arrival, however, upon use am very unhappy. The belt does not track properly and comes off the sander, even when using the tracking adjustment to the point it falls out! I contacted DeWalt and they advised taking it in for service as the tension spring is apparently malaligned, what is the point when it shoud have worked to begin with? I will have to take the unit for Warranty Repair, but since I needed it to paint the house, it seems to defeat the purpose.
