OPERATION
WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including splashing in the eyes or on the skin, injury from moving parts or electric shock, always follow this procedure when shutting off the system, when checking or servicing any part of the spray system, when installing, cleaning or changing fluid nozzles, and whenever you stop spraying.
1.Turn the ES ON±OFF Valve lever to OFF.
2.Turn off the air and fluid supply to the gun.
3.Trigger the gun into a grounded metal waste container to relieve fluid pressure.
4.Open the pump drain valve, having a waste container ready to catch the drainage.
5.Leave the pump drain valve open until you are ready to spray again.
Filter the Fluid
Filter the fluid to remove coarse particles and sediment which could clog the spray nozzle.

Operating Checklist
Check the following list daily, before starting to operate the system, to help ensure you of safe, efficient operation.
1.Be sure all operators are properly trained to safely operate an electrostatic air spray system.
2.Be sure all operators are trained how to prop- erly and completely relieve system pressure.
3.Be sure the system is thoroughly grounded. See FIRE OR EXPLOSION HAZARD on page 5, and Check the Electrical Grounding on page 8.
4.Be sure the operator and all persons entering the spray area are properly grounded by wear- ing shoes with conductive soles or personal grounding straps.
5.Operator must not wear gloves which insulate the hand from the spray gun. If worn, gloves must be conductive or modified as shown in Fig 3.
6.Be sure ventilation fans are operating properly.
7.Be sure the workpiece hangers are clean and grounded. Contact points must be sharp points or knife edges.
8.Be sure all refuse is removed from the spray booth.
9.Be sure all flammable liquids in spray booth are in approved, grounded containers.
10.Be sure all conductive objects within 20 ft (6 m) of the gun are electrically grounded and the floor of the spray area is electrically con- ductive and grounded.
Spraying Operation
This gun has a built±in lead and lag operation. The gun begins emitting air before the fluid is discharged. When you release the trigger, the fluid stops before the air flow stops. This helps prevent fluid buildup on the air cap.
When spraying, the ES indicator lights (BB) should glow, indicating the electrostatic charge. See Fig 2.
