DRIVE BELT WAS NOISY-SLIPPING

I just popped up the top front using a large straight (slotted) screw driver, then removed the 2 screws at the bottom front, then the whole front panel popped down about a half inch to be lifted out of the way. I found the old drive belt way down under the motor (still attached as normal), very near the floor and removed the worn out belt by hand, and replaced it with the new belt by hand also. The spring loaded belt tightener- idler wheel makes this a very simple process to accomplish. Then, I replaced the front panel-- all done. Works like new.
