Brushes & Springs
Check that brushes move freely in holders by holding back brush springs and pulling gently on the flex connectors. If movement is sluggish, remove brush from holder and clean sides with a gasoline moistened cloth. Replace brushes and springs when they have reached minimum specifications in specification table.
