I am by no means an expert but, a bad bearing could cause belts to derail. Rotate all rolls by hand and inspect for loose bearings or evidence of heating. Or it could be that one of the rollers needs to be adjusted and make sure the belts are routed correctly.ed2you said:belts track to right side
I do not see adjustment screw must be looking in wrong spotjltrent said:Adjust the roller behind as stated above. If the belts are tracking to the right adjust the left side of the roller behind. Turn adjustment screw clockwise. If tracking to the left adjust the roller on the right side turning the adjustment screw clockwise. You have to think back azzward adjusting those.
