Industrial Wet/Dry Vacuum Q&A
On Model 258 how can I connect the interceptor if I'm working with water too?
Why does my unit cycle on/off continually?
It sounds like you could have a problem with the daughterboard in your power unit. If you want to give us a call we could try a few things to help you troubleshoot your problem over the phone. Also I have attached a link to our troubleshooting guide.
