ELECTRIC SHOCK HAZARD

WARNING

ELECTRIC SHOCK HAZARD

Improper grounding or an improper setup can cause a hazardous condition and result in an electric shock or other serious injury.

DGround the equipment, personnel in or close to the spray area, the object being sprayed, and all other electrically conductive objects in the spray area. See Ground the System on page 14.

DThe gun must be connected to a voltage isolation system that will discharge the system voltage when the gun is not in use.

DComponents of the isolation system which are charged with high voltage must be inaccessible to personnel to avoid electric shock. These components must be contained in an enclosure or a safety fence that prohibits personnel from making contact with them before the system voltage is discharged.

DThe areas of the waterborne fluid hose that are accessible to the personnel must be covered by the conductive hose layer. The area on the hose that is not covered by the conductive hose layer must be inside the voltage isolation system enclosure. Refer to Fig. 6, page 13.

DOnly use the red-colored Graco electrically conductive gun air hose with this gun. Do not use the black or grey-colored Graco air hoses.

DInstall only one continuous Graco waterborne fluid hose between the isolated fluid supply and the spray gun. Do not splice hoses together.

DFollow the Fluid Voltage Discharge and Grounding Procedure on page 16 when instructed to discharge the voltage; before cleaning, flushing, or servicing the system; before approaching the front of the gun; and before opening the safety fence or the enclosure for the isolated fluid supply.

DDo not enter a high voltage or hazardous area until all high voltage equipment has been discharged.

DDo not come within 4 in. (101.6 mm) of the front of the gun until the Fluid Voltage Discharge and Grounding Procedure on page 16 has been completed.

DDo not connect more than one gun to the same fluid isolation system. Regulations applying to this type of equipment prohibit the use of multiple hand-held guns.

DIf there is any static sparking while using the equipment, stop spraying immediately. Identify and correct the problem.

DFollow the warnings and instructions in the voltage isolation system manual.
