I have a EZ-8 115/60 HDTR and have used it a little bit here and there. The last bigger job I had the drum kept pushing the paper to one side of the machine. I would get about 4-5 passes and I would have to re-center the paper in order to keep it from exposing the drum fingers. Do I have to buy a new drum? Or is there something I am missing here? I have never had to do anything on other machines other that slide the paper onto drum and get to rolling.

Thank you for your help.

Hi John—
On the belt sanders we use, there’s an adjustment for this, at the top of the drum. It uses allen wrenches, and it allows us to center the paper if it’s moving too far one way or the other. However, Hummel belts slide over more than one roller, which allows more adjustment.

The EZ-8 is a single roller, but it may have a similar adjustment, and you’ll have to call Clark tech support to find out where it is. I looked at two videos on Youtube for that model, and only one discussed putting on the belt. It did not talk about centering it. As you noted, most of the time you just slide on the belt, and it centers automatically.
