DESCRIPTION
The AGXV high volume, low pressure spray
gun (spray pistol) is used on automatic and
semi-automatic machines where mass produc-
tion spraying is necessary, or hand spraying is
not accurate enough. Models and application
information follows. All models are designed to
provide maximum transfer efficiency by limiting
air cap pressure to 10 psi (0.7 bar) (in the U.S.,
this complies with rules issued by SCAQMD and
other air quality authorities).Air cap pressure
can be measured with an optional air cap test
kit. See "ACCESSORIES" on Page 8.

Most finishing materials can be atomized with
the 33A air cap. The 33A cap should be used
where possible as it consumes less air volume
(CFM) and has slightly better transfer efficiency
than the 46 MP or 83MP air caps. However, more
difficult to atomize materials (i.e. low VOC's) or
high flow applications over 12 oz./min. (360 cc/
min.), are ideal for the 46 MP maximum per-
former air cap, fluid tip and baffle combination.
Also available is the 83MP (maximum performer)
for even higher flows 17 oz./min. (510 cc/min.)
and above and higher viscosities. Refer to the
air cap chart for more information.
Note
This gun may be used with chlorinated
solvents. Aluminum is not used in fluid pas-
sages. If using chlorinated solvents, make
sure all other fluid handling components
are also compatible.
A list of materials used in the construction
of this equipment is available upon request.

SAFETY PRECAUTIONS
This manual contains important information that ALL users should know and understand BEFORE using the equipment. This
information relates to USER SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we
use the following terms to draw your attention to certain equipment labels and portions of this manual. Pay special attention to
any label or information that is highlighted by one of these terms:

SB-2-628-T PAGE 3
INSTALLATION
Mount the gun with the stud (13) or on a 5/16" dia. rod tighten-
ing adequately with the 1/4-28 X 1/4" set screws (Ref. 24). See
"ACCESSORIES" for mounting clamps.
Note
If replacing the atomization air connection (15) with an
elbow type connection, be aware of a possible air flow
(CFM) limitation. A 1/4" (6.4 mm) I.D. 90° elbow will only
pass 20 CFM @ 40 psi (566 l/min. 2.7 bar). Some air caps
require more than 20 CFM (566 l/min.). Spray performance
could be affected.
Attach the trigger/cylinder air hose and the atomization air hose
to the connections as indicated by the markings on the gun body.
The air supply should be filtered and regulated. Attach the material
hose to the fluid inlet on the gun body. Fluid can be recirculated
by installing a fluid fitting (AGX-415) (order separately) at the
recirculating port. See Caution below.
The fluid inlet and recirculating ports have a tapered
seating surface intended for use with the AGX-415
fitting. Do not substitute other fittings as fluid leakage
will occur.

Details of actual noise levels produced by the various air cap/
fluid head setups are available upon request.
Noise Levels – Ear Injury A continuous A-weighted sound
pressure level of this spray gun
(spray pistol) may exceed 85
dB(A) depending on the air cap/
fluid head setup being used.
Sound levels are measured using
an impulse sound level meter
and analyzer, when the gun is
being used in a normal spraying
application.
HAZARD CAUSE SAFEGUARDS

The disposal of waste materials must be carried out in an approved manner. Burning may generate toxic fumes. The removal or
waste solvents and coating materials should be carried out by an authorized local waste disposal service.

PAGE 4 SB-2-628-T
OPERATION
1. Mix, prepare and strain the material to be sprayed according to the
paint manufacturer’s instructions. Use a lint free mesh to strain the
material.
2. Turn on the cylinder air at source of supply. Supply air should be a
minimum of 50 PSI (3.5 bar). For consistant operation the pressure
should be regulated. If 50 psi (3.5 bar) cylinder air pressure is not
available, the red inner spring (31) can be removed. This allows a
minimum cylinder pressure of approximately 37 psi (2.6 bar).
Note
If the red inner spring (31) is removed, atomization pressure
should not exceed 70 psi (4.8 bar) (will result in gun not shut-
ting off).
3. Turn the needle adjustment knob (25) counterclockwise several turns.
With the cylinder air on, turn the adjustment knob (25) clockwise until
it contacts piston (19) (for maximum fluid flow). Back knob out 1/2 turn.
Note
Due to close part tolerances, actuate the gun on and off 7 or
8 times to "break-in" the packings. Do this with the material
supply off.
4. Adjust the atomization air pressure to 50 PSI (3.5 bars) or less. Aways
attempt to keep the pressure as low as possible to minimize overspray.
The fluid pressure should be between 10 to 15 PSI (0.7 to 1.0 bar).
5. Open the hand valve and/or trip the automatic valve if installed in the
system and observe the spray pattern. Adjust the air and fluid pres-
sures until the desired pattern is obtained. Control the fluid pressure
at the source of supply. If the desired regulation is not practical at this
point, restrict the flow by turning the adjustment knob (25) clockwise.
Back Pressure – 46MP and 83MP "Maximum Performer"
Due to the unique cone shape of the MP fluid tips (nozzle), a slight back
pressure is created against the fluid column. This will reduce the amount
of fluid output. To compensate, increase the fluid regulator pressure
slightly if necessary. With 10 PSI (0.7 bar) cap pressure, back pressures
are approximately 3.5 PSI (0.24 bar) with the 46MP and 2.0 PSI (0.14 bar)
with the 83MP.
6. The width of the spray pattern is controlled by the adjusting valve (23)
marked “FAN” . With the “FAN” valve screwed fully clockwise, the
spreader air will be closed off causing a round pattern. By gradually
opening this valve, the pattern changes to a fan spray. The width is
determined by the amount the valve is opened. Atomization air is
adjusted by regulating the supply air to the gun.
Adjustments to fan may be controlled remotely by using the optional
KK-4955 fan control adapter to replace the AGG-403 control valve (23).
A separate solenoid valve is required to control on/off function. See
Figure 2A.
7. Close the automatic valves and begin operation.

PREVENTIVE MAINTENANCE
Risk of Injury. Equipment and fluid may be under pressure.
Pressure in the system must be relieved before beginning the
cleaning procedure and before replacing any parts. Follow
the procedures in the literature provided with the system.
Cleaning
1. Relieve air pressure from the pressure feed tank. Carefully fol-
low the instructions in the bulletin sent with the tank.
2. Replace material in the container with a suitable solvent.
3. Repressurize the system.
4. Trigger the gun and repeat the procedure until the gun and hose
are thoroughly clean (solvent is clean when it looks the same
as when you first opened solvent container). A SolventSaver™
type hose and gun cleaner which supplies a mixture of air and
solvent can be used to most effectiverly clean the gun and hose
internal passages. See "Accessories" on back page. Wipe the
exterior of the gun with a solvent dampened cloth.
5. If a recirculating system is used, it may be necessary to fit a shut
off valve in the return line to ensure the fluid tip and forward
portion of the sprayhead passage are properly cleaned when
flushed with solvent.
Do not totally submerge the gun in solvent. It is possible
to wash solids into the air operating sections of the gun
which could damage piston "O" ring seals.
The air cap can be immersed in solvent for cleaning. If
the orifices are clogged, use a broom straw or toothpick
to remove the obstruction. Never use a steel wire or hard
instrument. This will damage the air cap and result in a
distorted spray pattern.

3. Remove fluid tip (3).
To avoid serious gun damage, do not remove the fluid
tip (nozzle) (3) from the spray gun (spray piston) when
the fluid inlet adaper (6 or 9) is removed. Doing so may
allow the stainless steel insert to break free from the
aluminum body, which is non-repairable.
4. It is recommended that both the fluid tip (nozzle) (3) and the
needle (28) be replaced at the same time. The needle packings
(11) should also be replaced when replacing the needle.
5. Remove adjusting knob (25).
6. Remove needle (28) with pliers.
7. Loosen four screws (7) and remove sprayhead (8).
8. With the sprayhead (8) removed, the packings (11) can be easily
removed and replaced.
9. Slide onto the new needle (28), in this order, 1 packing (11),
spring (12) and 1 packing (11). Be sure to orient the packings
as shown (Figure 4).
10. Assemble sprayhead (8) with retaining screws (7).
11. Tighten screws (7) with a 3/16 hexagon key 30-40 in. lbs.

Halogenated Hydrocarbon solvents can chemically react
with aluminum. A risk of explosion or severe corrosion
will occur. The following assembly step must be care-
fully performed.
If replacing AGX-415 inlet fitting, or if it should loosen, follow the
assembly procedures below, and refer to Figure 3.
1. If installing a used fitting, clean paint and thread sealant from
the fitting threads and gun body.
2. Screw the jam nut all the way onto the fitting. Then apply a
medium strength thread sealant (i.e. Loctite 242 blue, or equal)
to the first few threads of the fitting.
3. Install the AGX-415 fitting into the spray gun and tighten to a
maximum of 12 ft. lbs. (16.3 N-m) torque. (Do not overtighten,
damage may occur.)
4. Tighten the jam nut to 16 ft. lbs. (21.7 N-m) torque using a thin
9/16" open end wrench.
5. Use two adjustable wrenches when removing a hose connec-
tion from AGX-415 to prevent the inlet fitting from loosening.
LUBRICATION
The piston O-rings (17 and 18) must be lubricated when the piston
(19) is removed. Lightly lubricate with clean petroleum jelly. Do
not use silicone-based lubricants. Petroleum jelly is effective as a
lubricant up to approximately 110°F (43°C). Above 110°F (43°C),
petroleum jelly will become "liquid" and will not lubricate the O-rings
adequately. If the ambient temperature adjacent to the spray gun
exceeds 110°F (43°C), use Parker O-Lube or suitable high temperature
grease. This allows the spray gun to be used in temperatures up
to 150°F (65° C) continous without lubrication degradation.
Lubricate the outside of the larger piston spring (30) and needle
spring (27) with a light coating of non-silicone grease. Apply a thin
film of petroleum jelly (petroleum based grease) to the fluid needle
(28) as shown in the "Note" on Page 6.
Note
Due to close part tolerances, after repairing the gun, actuate
the gun on and off 7 or 8 times to "break-in" the air packing
(20). Do this with the material supply off.

PROBLEM CAUSE CORRECTION
TROUBLESHOOTING
Proper gun adjustment will result in normal spray patterns, from
round with the fan control valve (23) closed, to long and narrow
with the valve open. Pattern width depends upon how much
the valve is opened, the type of air cap used and fluid flow rate.
NORMAL SPRAY PATTERN
The proper combination of fluid pressure, fan and
atomization air pressure, and fluid tip size should
result in a pattern of this shape.
Note
To determine where the material build up is, rotate the air cap 180° and test spray. If the pattern
stays in the same position, the condition is caused by material build up on the fluid tip (nozzle). If the
pattern changes with air cap movement, the build up is in the air cap.
