Firstly let me admit i am new to this belt sander, Lagler Hummel belt sander. I have seen numerous videos on Utube and the performnce of the machine was great. However i tried mine today on oak floor but as i ran the machine diagonally across the floor i see a very small track about 4" thats being cut. Please advise. i did try increasing the drum pressure but it docent help. Please advise
