General Safety the gun, leaks or ruptured components can inject fluid through your skin and into your body and cause extremely serious bodily injury, including the need for amputation. Also, fluid injected or splashed into the eyes or onto the skin can cause serious damage. metal pail, holding the gun firmly to the pail. Using the lowest possible pressure, trigger the gun. If the fluid emitted is not diffused into an irregular stream, replace the diffuser im- mediately.
Tip Safety
NEVER point the spray gun at anyone or at any part of the body. NEVER put hand or.fingers over the spray tip. NEVER try to "blow back" paint; this is NOT an air spray gun. the spray tip clogs while spraying, engage the gun safety latch immediately. ALWAYS follow the Pressure Relief Pro- cedure, below, and then remove the spray tip to clean it.
ALWAYS follow the Pressure Relief Procedure, at right, before cleaning or removing the spray tip or servicing any system equipment.
NEVER wipe off buildup around the spray tip or air cap until pressure is fully relieved and the gun safety latch is engaged.
NEVER try to stop or deflect leaks with your hand or body.
CHECK operation of all equipment safety devices before each use.
To reduce the risk of serious bodily injury, including fluid in- jection, splashing in the eyes or on the skin, or injury from moving parts, always follow this procedure whenever you shut off the pump, when checking or servicing any part of the spray system, when installing, cleaning or changing spray tips, and whenever you stop spraying:
Note to Physiclan: Injection in the skin is a traumatic in- jury. It is important to treat the injury surgically 8s soon as possible. Do not delay treatment to research toxicity.
Toxicity directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.
Spray Gun Safety Devices each use. Do not remove or modify any part of the gun; this can cause a malfunction and result in serious bodily injury.
Safety Latch
Whenever you stop spraying, even for a moment, always set the gun safety latch in the closed or "safe" position, making the gun inoperative. See Fig 3,
Failure to set the safety latch can result in accidental triggering of the gun.
Diffuser
The gun diffuser breaks up spray and reduces the risk of fluid injection when the tip is not installed. Check diffuser operation regularly. Follow the Pressure Relief Procedure, at right, and then remove the spray tip. Aim the gun into a grounded

INSTALLATION
The Typical Installation drawing above is only a guide
.for selecting and installing air-assisted airless spray systems. It is not an actual system design. Contact your
Graco representative for assistance in designing a system to meet your needs.
The Graco fluid pump Model 217-523 is designed for use in air-assisted airless systems. It has ing pressure of 950 psi ( 6 6 bar). See a maximum work- instruction manual
307-595 for information on pump Model 217-523.
Ventilate the Spray Booth
WARNING
To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth.
NEVER OPERATE THE SPRAY GUN UNLESS
VENTILATION FANS ARE OPERATING.
Check and follow all of the National, State and
Local codes regarding air exhaust velocity re- auirements.
Required Accessories
WARNING
Two accessories, the bleed-type master air valve
(Cl, and the fluid drain valve (El are required for your system to reduce the risk of serious bodily in- jury from moving parts, splashing, or fluid injec- tion when shutting off the pump.
The bleed-type master air valve relieves air trap- ped between the valve and the pump, after the pump is shut off. Trapped air can cause the pump to cycle unexpectedly and result in serious bodily injury if you are adjusting or repairing the pump. ting .off the pump. Triggering the gun to relieve pressure may not be sufficient, especially if there is a clog in the hose, gun, or tip.

How the Air-Assisted Airless Spray Gun Works
The air-assisted airless gun combines airless and air spraying concepts. The spray tip shapes the fluid into a fan pattern, similar to a conventional airless spray tip, but at a lower pressure. Air from the air cap further atomizes the fluid and completes the atomization of the paint tails into the pattern. The pattern adjustment valve controls the width of the pattern.
The spray gun has a built-in lead 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 air cap. is atomized and prevents fluid buildup on the
Note that the air-assisted airless spray gun differs from an air spray gun in that increasing the pattern air reduces the pattern width. To increase the pattern width, less pattern air or a larger size tip must be used.
Remember, this is not an air spray gun; safety be sure page 2 and

Install a Spray Tip
WARNING
To reduce the risk of a fluid injection injury, follow the Pressure Relief Procedure
on page 2 before removing or installing a spray tip.
Install a spray tip in the gun. The air cap and Spray tip position determines the direction of the spray pattern.
Rotate the air cap (the spray tip rotates with it) as needed for the desired spray pattern direction. See
Adjust the Spray Pattern and Apply the Fluid
WARNING
To reduce the risk of serious bodily injury, including fluid injection, skin: and splashing in the eyes or on the
1. NEVER point the spray gun at anyone or any part of the body or put your hand or fingers over the spray tip when adjusting the spray pattern or spraying fluid.
2. ALWAYS engage the trigger safety latch when you stop spraying. See Fig 3.
3. NEVER exceed the maximum air and fluid working pressure of the lowest rated compo- nent in your system. See System Pressure in the EQUIPMENT MISUSE HAZARD Sec-
1. Set the fluid pressure at 300 psi (21 bar). Trigger the gun to check the atomization; don't be concerned about the pattern shape yet. Increase the fluid pressure just to the point where a further increase in fluid pressure does not significantly improve fluid atomization. DO NOT exceed 950 psi ( 6 6 bar) fluid pressure to the gun.
2. Close the pattern adjustment valve (P) by turning the knob counterclockwise all the way. (This sets the gun for its widest pattern.)
NOTE: If you are using the Fine Finish Air Cap, part no. 219-093, the pattern adjustment valve must be open (turned fully clockwise) when operating the gun.
3. Set the atomizing air pressure at into the spray pattern. clockwise. See
See Fig

Check the spray pattern, then adjust the air pressure until all the tails are completely atomized and pulled

4. tern, turn the pattern adjustment valve knob
NOTE: For some spray tips, when the line air pressure to the gun is increased to a certain level, the spray pattern will become round.
This is the smallest pattern width. Further in- creases in air pressure will force the pattern to turn from horizontal to vertical or from ver- tical to horizontal.

Pressure Relief Procedure
To reduce the risk of serious bodily injury, in- cluding fluid injection, splashing in the eyes or on the skin, or injury from moving parts, always follow this procedure whenever you shut off the pump, when checking or servicing any part of the spray system, when installing, cleaning or chang- ing spray tips, and whenever you stop spraying:
1. Engage the gun safety latch.
Shut off the power to the pump.
3. Close the bleed-type master air valve (required
5. in your system).
Disengage the gun safety latch.
Hold a a metal part of the gun firmly to the side of metal pail, and trigger the gun to relieve pressure.
6. Engage the gun safety latch. -
7. Open the pump drain valve (required in your system) to help reliave fluid pressure in the displacement pump. In addition, open the drain valve connected to the fluid pressure gauge (in a system with fluid regulation) to help relieve fluid pressure in the hose and gun. Triggering the gun to relieve pressure may not be suffi- cient. Have a container readv to catch the drainage.
8. Leave the drain valve(s) open until you are ready to spray again.
If you suspect that the spray tip or hose is com- pletely clogged, or thatpressure has not been fully relieved after following the steps above, VERY
SLOWLY loosen the air cap or hose end coupling and relieve pressure gradually, then loosen com- pletely. Now clear the tip or hose.
