Safety

SKIN INJECTION HAZARD

Remember, this is not an air spray gun. For your safety be sure to read and follow the Warnings on pages4 and5 and throughout the text of this instruction manual.

Keep the wallet sized warning card (222385), provided with the gun, with the operator of this equipment at all times. The card contains important treatment information should an injection injury occur. Additional cards are available at no charge from Graco.

Pressure Relief Procedure

SKIN INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

are instructed to relieve the pressure,

stop spraying,

check or service any of the system equipment,

or install or clean the spray tip.

Follow Pressure Relief Procedure on page 10 when you stop spraying and before cleaning, checking, servicing, or transporting equipment. Read Warnings, page 4.

1.Engage the trigger lock. See FIG. 13.

2.Shut off the pump. See your pump manual.

3.Shut off the gun air supply.

4.Disengage the trigger lock. See FIG. 13.

5.Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure. See FIG. 12.

TI6555A

FIG. 12

6.Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.

7.Engage the trigger lock. See FIG. 13.

8.If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the tip guard retaining ring or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction.

Trigger Lock

Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped.

How the Air-AssistedSpray Gun

Operates

The air-assistedspray gun combines airless and air spraying concepts. The spray tip shapes the fluid into a fan pattern, as does a conventional airless spray tip. Air from the air cap further atomizes the fluid and completes the atomization of the paint tails into the pattern to produce a more uniform pattern. The width of the pattern can be adjusted by the pattern adjustment valve.

The air-assistedspray gun differs from an air spray gun in that increasing the pattern air reduces the pattern width. To increase the pattern width, use less pattern air or a larger size tip.

The spray gun has a built-inlead and lag operation. When triggered, the gun begins emitting air before the fluid is discharged. When the trigger is released, the fluid stops before the air flow stops. This helps assure the spray is atomized and prevents fluid buildup on the air cap.

Spray Pattern Adjustment

SKIN INJECTION HAZARD

To reduce the risk of component rupture and serious injury, including injection, do not exceed the gun’s maximum fluid working pressure or the maximum working pressure of the lowest rated component in the system.

1.Do not turn on the gun air supply yet. Set the fluid pressure at a low starting pressure. If a fluid pressure regulator is installed, use it to make adjustments.

If your system does not have a fluid regulator, the fluid pressure is controlled by the air regulator supplying the pump, per the formula below:

Pump x Pump Air Regulator Setting =

Fluid

Ratio

Pressure

2.Trigger the gun to check the atomization; do not be concerned about the pattern shape yet.

Operation

3.Slowly increase the fluid pressure, just to the point where a further increase in fluid pressure does not significantly improve fluid atomization.

4.Close off the pattern adjustment air by turning the knob clockwise (in) all the way. See FIG. 14. This sets the gun for its widest pattern.

CLOSE

OPEN

TI6559A

FIG. 14

5.Set the atomizing air pressure at about 5 psi (3.5 kPa, 0.35 bar) when triggered. Check the spray pattern, then slowly increase the air pressure until the tails are completely atomized and pulled into the spray pattern. See FIG. 15. Seven to 10 psi (4.9 to 7.0 kPa, 0.49 to 0.7 bar) air pressure is typically enough to atomize the tails, especially for low viscosity materials. Setting the air pressure too high will cause material to build up on the air cap and decrease transfer efficiency. Do not exceed 100 psi (0.7 MPa, 7 bar) air pressure to the gun.

For a narrower pattern, turn the pattern adjustment valve knob counterclockwise (out). See FIG. 14. If the pattern is still not narrow enough, increase the air pressure to the gun slightly or use a different size tip. (Not available for RAC tip guns.)

Operation

HVLP Operation

For HVLP operation, the atomization air must not exceed 10 psi. Use HVLP Verification Kit 249140 to verify air psi.

There is no fan adjustment when using RAC tips and caps.

1.To achieve the best results when applying fluid, keep the gun perpendicular to the surface and maintain a consistent distance of approximately 8 to 12 in. (200 to 300 mm) from the object being sprayed.

2.To obtain an even finish, use smooth, even strokes across the object being sprayed with 50% overlap.

3.Paint using parallel strokes. This spray gun applies all coatings evenly without cross coating.

Fluid Application

Always hold the gun at a right angle from the surface. Do not make an arc with the gun as it causes an uneven coat of fluid. See FIG. 16.

If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid.
