My conveyor belt is working intermittently and mostly not working at all. Sometimes it will start up and then stop after 5 seconds. I read the manual and adjusted the conveyor belt tensioners and that’s not it. Also tightened the sleeve (2 Allen wrench adjustments) between the conveyor motor and the conveyor drive and that’s not it either. In fact, when I loosen the sleeve altogether, and turn the conveyor belt motor on, I can see the motor stop even with zero tension on the conveyor sleeve. Can someone help me with a solution. I miss my drum sander.
