If the E-Stop has been activated it is recommended all striping function switches, master switch, furnaces, pumps, guns, etc. be turned off prior to resetting the E-Stop switch. It is necessary to bleed the compressed air from the air compressor receiver tank prior to re-starting the air compressor.
