Manual states: Never override the thermal breaker. | | Bird-nesting at drive roll | Gun liner debris or excessive drive roll pressure | Blow out liner with compressed air; reduce pressure to just before slipping. | The original Century Powermate 70 manual includes an exploded-view diagram and a parts list.
