• Interlock the gun air supply with the voltage isolation system to shut off the air supply anytime the isolation system enclosure is opened. • Only use the red-colored Graco electrically conductive air hose with this gun. Do not use black or gray-colored Graco air hoses. - Page 5 • Do not stop or deflect leaks with your hand, body, glove, or rag. • Follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses and couplings daily. Replace worn or damaged parts immediately. 333013B...
- Page 6 • Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces. • Do not kink or over bend hoses or use hoses to pull equipment. • Keep children and animals away from work area. • Comply with all applicable safety regulations. 333013B...
