If gloves are necessary, wear the conductive gloves supplied with the gun. If non-Graco gloves are worn, cut off fingers or palm area of gloves to ensure your hand contacts the grounded gun handle.
Failure to follow this warning could cause fire, explosion, and electric shock and result in serious injury and property damage. Graco Part No. 241079 Megohmmeter is available as an accessory to check that the gun is properly grounded. 1. Have a qualified electrician check the electrical grounding continuity of the spray gun and air hose.
Gun Setup 7. If the resistance is greater than 100 ohms, check the tightness of the ground connections and be sure the air hose ground wire is connected to a true earth ground. If the resistance is still too high, replace the air hose. 8.

To help prevent serious injury from pressurized fluid, such as skin injection, 6. Trigger the gun into a grounded metal waste splashing fluid and moving parts, follow the container to relieve the fluid pressure.
Operation Fill the Fluid Supply 6. Clean up any fluid spills in the enclosure, using a soft cloth and a non-flammable, compatible solvent. 1. Follow the Fluid Voltage Discharge and Grounding Procedure, page 7. Fill the supply pail with fluid and return it to the enclosure.
