All electrical cables must be properly grounded. • All persons entering the spray area: shoes must Graco Part No. 241079 Megohmmeter is available as an have conductive soles, such as leather, or personal accessory to check that the gun is properly grounded.
Failure to follow this warning could cause fire, explosion, and electric shock and result in serious injury and property damage. Graco Part No. 722886 Resistance Meter and 722860 Probe are available as accessories to check that the resistivity of the fluid being sprayed meets the require- ments of an electrostatic air spray system.
Operation Operation Pressure Relief Procedure Startup Follow the Pressure Relief Procedure whenever Check the following list daily, before starting to operate you see this symbol. the system, to help ensure you of safe, efficient opera- tion. All operators are properly trained to safely operate an automatic electrostatic air-assisted spray system as instructed in this manual.

Operation Adjust the Electrostatics Spraying 1. Turn on the turbine air (TA) and adjust the air pres- sure per the settings in Table 1 . Set the proper pressure at the turbine air hose inlet when air is flowing. To reduce the risk of electric shock, do not touch the gun electrode or come within 4 in.
Maintenance Maintenance To reduce the risk of an injury, follow the Pressure To reduce the risk of fire and explosion, turn off the Relief Procedure before doing any maintenance on turbine air (TA) before flushing the gun and always the gun or system. ground equipment and waste container.
Maintenance Clean Outside of Gun Clean the Spray Gun NOTICE Equipment Needed • Clean all parts with a non-conductive, compatible • soft bristle brush solvent. Conductive solvents can cause the gun to • compatible solvent malfunction. • Fluid in the air passages could cause the gun to Procedure malfunction and could draw current and reduce the electrostatic effect.
Maintenance NOTE: Use two wrenches to remove the fluid tube fitting 13. Test Gun Resistance, page 22. (C). Check for Fluid Leakage If any fluid leakage from the gun is detected, stop spraying immediately. Fluid leakage into the gun shroud could cause fire or explosion and result in serious injury and property damage.
Electrical Tests Electrical Tests Electrical components inside the gun affect performance and safety. The following procedures test the condition of the power supply (7) and electrode (25a), and electri- cal continuity between components. NOTICE The barrel resistor cartridge is part of the barrel and is not replaceable.
• Never operate the gun without the conductive ring in place. • Do not replace the conductive ring with anything but a genuine Graco part. 5. If the resistance is still outside the range, replace the gun barrel. 333011D...
Troubleshooting Troubleshooting Installing and servicing this equipment requires To reduce the risk of a fluid injection injury, always access to parts which may cause an electric shock or follow the Pressure Relief Procedure on page 16 other serious injury if the work is not performed when you stop spraying and whenever you are properly.
Troubleshooting Gun Operation Troubleshooting Problem Cause Solution Excessive spray fog. Atomizing air pressure too high. Decrease air pressure (A1) as low as possible Fluid too thin. Increase viscosity or increase fluid flow rate. “Orange Peel” finish. Atomization air pressure too low. Increase air pressure;...

Troubleshooting Problem Cause Solution Gun does not spray Low fluid supply. Add fluid if necessary. Damaged spray tip. Replace; see Air Cap/Tip Guard, Spray Tip, and Fluid Seat Housing Replacement page 29. Dirty or clogged spray tip (3). Clean; see Clean the Spray Gun, page 20.
Troubleshooting Electrical Troubleshooting Problem Cause Solution Poor wrap. Turbine air is not turned on. Turn on. Booth exhaust velocity is too high. Reduce velocity to within code limits. Atomization air pressure too high. Decrease. Fluid pressure too high. Decrease, or replace worn tip. Incorrect distance from gun to part.
