Ive had this tool for two years and have failed to solve the feed belt tracking problem it came with.It requires adjustment every few minutes or the belt runs off to one side and will shred the edge if not adjusted.Woodcraft (where I bought it) said it was me and not the tool.I called the tech dept. at Jet and this guy said a different brand of drive belt would fix it.He sent a new Bear brand belt and the tracking failed to improve.I have tried more and less tension,etc to no avail.This is a very useful tool except for this REALLY annoying problem.Does anyone have any suggestions? I think I got a lemon or it was dropped on its head as a baby at the factory!

The one thing I can suggest is …. make your adjustments in very small increments, and give it a LOT of time to “normalize.”

It’s very easy to turn the nut too far, and overshoot your target.

Of course, then you turn it too far the other way, and … overshoot your target again.

Make small adjustments, and wait a while (a few minutes) to see what effect each adjustment has.

I followed the instructions to adjust a quarter turn at a time,but it doesnt seem to do anything.

How about 1/3 of a turn at a time, then, and … then … waiting.

I’m not going to be able to explain this very well, but … there are two nuts on my 16/32 that—if you have NOT loosened THEM first … you’re NOT going to have ANY luck adjusting the tracking of the conveyor belt.

Hopefully, you know what I’m talking about.

I saw them right away, when I installed my new conveyor belt, but … realized that … if I hadn’t seen them, NO adjustments would have been possible.

You sure the right things are tight, and the right things are loose ?
