Installation

Air Line and Accessory
Recommendations

1. Install an air pressure regulator on the gun cylinder
air supply line.

A minimum of 70 psi (0.49 MPa, 4.9 bar) air pres­sure must be supplied to the cylinder for proper
operation. Air pressure opens the valve, a spring
closes the valve. A three-way air valve, which
exhausts cylinder air, is required.

2. Install a bleed-type air shutoff valve on the main air
line. Install an additional bleed-type valve on each
pump air supply line, downstream of the pump air
regulator, to relieve air trapped between this valve
and the pump after the air regulator is shut off.

WARNING

The bleed-type air shutoff valve is required in your
system to relieve air trapped between this valve
and the pump after the air regulator is closed.
Trapped air can cause the pump to cycle unexpect­edly, which could result in serious injury.

Fluid Line and Accessory
Recommendations

WARNING

INJECTION HAZARD

To reduce the risk of property damage or
serious injury, including injection, which
could be caused by component rupture
or unrelieved fluid pressure,

 A fluid drain valve(s) is required in your system

to assist in relieving fluid pressure in the dis­placement pump, hose and gun; triggering the
gun to relieve pressure may not be sufficient.

 A fluid pressure regulator must be installed in

the system if the pump’s maximum working
pressure exceeds the gun’s maximum fluid
working pressure (see the front cover).

1. Install a fluid filter and drain valve(s) close to the
pump’s fluid outlet.

2. Install a fluid pressure regulator to control fluid
pressure to the gun.

NOTE: Some applications require fine-tuned control of
fluid pressure. You can control fluid pressure more
accurately with a fluid pressure regulator than by
regulating the air pressure to the pump.

3. Install a bleed-type air shutoff valve on the gun air
cylinder supply line, downstream of the air regula­tor, to shut off air to the gun cylinder. Connect the
air supply line to the gun cylinder air inlet (C). See
Fig. 4.

NOTE: The cylinder air inlet accepts 1/4 in. (6.3 mm)
O.D. tubing.

3. Install a fluid shutoff valve to shut off the fluid
supply to the gun.

4. For paint spray applications, install an in-line fluid
filter, part no. 210500, on the gun fluid inlet (F) to
avoid clogging the spray tip with particles from the
fluid. See Fig. 4.

5. Connect the electrically conductive fluid hose to
the gun fluid inlet (F) or optional in-line filter.

Ground the System

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding could cause static
sparking, which could cause a fire or
explosion. To reduce the risk of property
damage or serious injury, follow the
grounding instructions below.

The following grounding instructions are minimum
requirements for a system. Your system may include
other equipment or objects which must be grounded.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Your
system must be connected to a true earth ground.

1. Pump: Ground the pump by connecting a ground
wire and clamp between the fluid supply and a true
earth ground as instructed in your separate pump
instruction manual.

2. Air compressors and hydraulic power sup-
plies: Ground them according to the manufacturer
recommendations.

3. Air, fluid, and hydraulic hoses connected to
the pump: Use only electrically conductive hoses
with a maximum of 500 feet (150 m) combined
hose length to ensure grounding continuity. Check
the electrical resistance of your air and fluid hoses
at least once a week. If the total resistance to
ground exceeds 29 megohms, replace the hose
immediately.

NOTE: Use a meter that is capable of measuring
resistance at this level.

4. Spray gun: Ground the gun by connecting it to a
properly grounded fluid hose and pump.

5. Fluid supply container: Ground it according to
local code.

6. Object being sprayed: Ground it according to
local code.

7. All solvent pails used when flushing: Ground
them according to local code. Use only metal pails,
which are conductive. Do not place the pail on a
non-conductive surface, such as paper or card­board, which interrupts the grounding continuity.

Safety

WARNING

INJECTION HAZARD

Remember, this is not an air spray gun.
For your safety be sure to read and
follow the Warnings on pages 2 and 3
and throughout the text of this instruction
manual.

Keep the wallet sized warning card, 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

WARNING

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.

1. Shut off the power to the pump.

2. Close the bleed-type master air valve (required in
the system).

5. Leave the drain valve(s) open until you are ready
to spray again.

6. If you suspect that the spray tip or hose is com­pletely clogged or that pressure has not been fully
relieved after following the steps above, very
slowly loosen the hose end coupling and relieve
pressure gradually, then loosen the coupling
completely. Now clear the tip or hose obstruction.

Install a Spray Tip

WARNING

INJECTION HAZARD

To reduce the risk of an injection injury,
follow the Pressure Relief Procedure
at left before removing or installing a
spray tip.

WARNING

INJECTION HAZARD

To reduce the risk of component rupture
and serious injury, including injection, do

not exceed the gun’s maximum fluid
working pressure (see the front cover) or the
maximum working pressure of the lowest rated
component in the system.

1. Make sure there is no pressure in the system.
Follow the Pressure Relief Procedure at left.

Models 239786 and 241469
with GG0 and GG1 Series Spray Tips

2. Install the spray tip (H) and the gasket (J) in the tip
retainer nut (K). Screw the assembly firmly onto
the gun. Tighten the assembly with a wrench. See
Fig. 6.

3. Trigger the gun to relieve the fluid pressure.

4. Open the pump drain valve (required in the sys­tem) to help relieve 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 sufficient. Have a container
ready to catch the drainage.

Operation

Adjust Spray Pattern

1. To adjust the spray pattern direction with fan tips,
orient the slot in the tip horizontally for a horizontal
pattern and vertically for a vertical pattern. See
Fig. 7.

2. Start the pump. Adjust the fluid pressure until the
spray is completely atomized. Use the lowest
pressure necessary to get the desired results.
Higher pressure may not improve the spray pattern
and will cause premature tip wear and pump wear.

3. The spray tip orifice and spray pattern angle
determines the coverage and size of pattern.
When more coverage is needed, follow the Pres-
sure Relief Procedure on page 9, and install a
larger spray tip rather than increasing fluid pres­sure.

Clean the Spray Gun and System Daily

WARNING

INJECTION HAZARD

To reduce the risk of an injection injury
or splashing fluid in the eyes or on the
skin:

 Follow the Pressure Relief Procedure on page

9 before cleaning, removing, or installing a

Reassembly

1. Perform the following applicable step:

 Non-circulating Paint Guns: Lubricate the back-

up (6) and o-ring (5) and install them on the
fluid outlet port plug (4). Install the plug in the
fluid outlet port of the fluid housing (2). See
Fig. 9.

 Circulating Paint Guns: Reinstall the filter (32)

in the fluid inlet port and the gasket (3) in the
fluid housing (2).

 Sealant Gun: Reinstall gasket (3).

2. Install the o-rings (22*, 23*) on the piston (21).
Install two o-rings (25*, 26*) on each of the piston
stems (T). Lubricate all the o-rings, the piston, and
the piston stems.

3. Insert the piston (21) into the piston housing (1).

4. Remove the protective paper from the sticky side
of the gasket (13*) and adhere the gasket to the
bottom of the piston housing (1), making sure the
three holes in the gasket are properly aligned with
the matching holes in the housing.

5. Install the fluid housing (2) on the piston housing
(1). Torque the four screws (15) to 65 in-lb (7.3
Nm).

CAUTION

Install a new gasket (11) whenever you remove the
seat (10) from the gun. Failure to install a new gas­ket may result in fluid leaking into the air chamber.

6. Install the o-rings (31) on the fluid needle assem­bly (12). Lubricate with light weight oil.

CAUTION

Be sure to keep the needle straight when installing it
in the piston housing. If the needle is bent it must be
replaced.

7. Insert the needle assembly (12) into the front of
the fluid housing (2). Push it straight back through
the piston.

8. Install a new gasket (11) in the fluid housing (2).

9. Lubricate the threads of the seat (10). Screw it into
the fluid housing (2) and torque to 20–25 ft-lb
(27–34 Nm).

10. Install the needle stop (17) on the needle. Coat the
setscrew (16) with semi-permanent anaerobic
sealant and install the screw into the needle stop.
Torque to 4–5 in-lb (0.45–0.56 Nm). Pull on the
needle to make sure it seats fully.

11. Install the springs (19, 20).

12. Lubricate the threads of the piston housing (1).
Screw the cap (18) onto the housing until it bot­toms out.

13. Do not lubricate the gasket (8). Install the spray
tip (9) and gasket (8) in the tip retainer nut (7).
Screw the assembly firmly onto the gun. Tighten
the assembly with a wrench, but do not exceed
5 ft–lb (6.8 Nm) for model 233670 gun.

14. Reinstall the gun on the manifold with the four
screws (14). Torque to 65 in-lb (7.3 Nm).

*Fluid output at 600 psi (4.1 MPa, 41 bar).

Fluid output (Q) at other pressures (P) can be calculated by this
formula: Q = (0.041) (QT) (

qP ).

Where QT = Fluid output (fl oz/min) from the above table for
the selected orifice size.

determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accor­dance with Graco’s written recommendations.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub­stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. 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. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.
