I have two questions. First I have a preformax wide belt sander 22-44. And I keep tearing the paper. Right at the end of the wrap where it goes in the clip. Sometimes right there and some times a little further back. What could I be doing wrong? And the next question is. Is there a way I can fix thoese torn belts. Thanks

Are you putting the belts on backwards? If the visible edge of the lap is moving the wrong way, it will eventually peel back and tear your belt.
Not that I know. I thought there was only one way to put them on.
I've got a 16-32 and have had breaks like you describe. Every time it's happened though, they've broken immediately upon powering up after changing grits. Are yours breaking like this or just through wear? With the lid of the unit closed, it was a bit hard to figure out why this was happening, but think I was finally able to trace the problem to tensioning of the roll on the drum. At least I've had a LOT fewer occurrences since I started paying more attention to this. Basically if you end up with any slack in the wrap on the drum, you get a crack-the-whip type effect on the end which ends up breaking. If that's the kind of break you're getting, keep the wrap VERY taut on the drum as you're applying it. When you get to the end, if you've got any slack at all going into the clip, start over. If you have to start over - instead of completely unrolling and starting at the first end you clipped you can do this: Insert as much of the end as you can into the (2nd) clip, then roll backwards as you tension til you get back to the starting clip. Whatever slack you had at the 2nd clip you should be able to completely push back into the starting clip and lock.
