I have taken a job at a High School which has a variety of equipment that is showing signs of wear. I don't seem to have manuals for them. The pottery wheels are suffering from a variety of ailments;
1. A Skutt that stops occasionally when the pedal is not depressed. The switch has to be turned off and on, and then motor starts up again.
2. A Shimpo that has to turned on for about 5 minutes before it will spin, and then the wheel head spasms. It spins and stops, spins and stops.
Can you help with repair suggestions/point me to sites where I can learn? Thanks!!
