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 serv- icing any part of the spray system, when installing, cleaning or changing fluid nozzles, and whenever you stop spraying.
1.Turn off all the air to the gun except the cylinder (actuating) air.
2.Turn off the fluid supply to the gun.
3.Trigger the gun into a grounded metal waste con- tainer to relieve fluid pressure.
4.Engage the gun safety latch.
5.Open the pump drain valve, having a waste con- tainer ready to catch the drainage.
6.Leave the pump drain valve open until you are ready to spray again.
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 automatic 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, page 5, and Check the Electrical Grounding, 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.Be sure ventilation fans are operating prop- erly.
6.Be sure the work piece hangers are clean and grounded. Contact points must be sharp points or knife edges.
7.Be sure all refuse is removed from the spray booth.
8.Be sure all flammable liquids in the spray booth are in approved, grounded containers.
9.Be sure all conductive objects within 6 m (20 ft) of the gun are electrically grounded and the floor of the spray area is electrically con- ductive and grounded.
Filter the Fluid
Filter the fluid to remove coarse particles and sediment which could clog the spray nozzle.
Spraying Operation
This gun has a
Adjust the system's control device, if it is automatic, so the gun starts spraying just before meeting the work piece, and stops as soon as the work piece has passed.
When spraying, the ES indicator lights (BB) should glow, indicating the electrostatic charge. See Fig 4.
Selecting a Fluid Nozzle and Air Cap
WARNING
To reduce the risk of serious bodily injury, including splashing in the eyes or on the skin or electric shock, always follow the Pressure Relief Proce- dure, above, before installing, or removing the fluid nozzle/air cap assembly.
This gun is supplied with fluid nozzle 181±299 and air cap 180±739. See Instruction Manual 307±803 for air cap consumption and fluid nozzle flow rate information.
The fluid output and pattern shape depends on the fluid nozzle size, fluid viscosity, and fluid pressure. If your application requires a different nozzle and air cap combi- nation, use manual 307±803 to select the appropriate fluid nozzle and air cap.
To install a different fluid nozzle and air cap, see To Clean or Change Air Cap and Fluid Nozzle, page 12.
