Important：Read and follow all instructions and SAFETY PRECAUTIONS before using this equipment.

Retain for future reference.

DESCRIPTION

The AGX spray gun is used on automatic and semi-automatic machines where mass production spraying of articles is
necessary or hand spraying is not accurate enough. Models and application information follows.

NOTE:

This gun may be used with chlorinated solvents. Aluminum is not used in fluid passages. If using chlorinated
solvents, make sure all other fluid handling components are also compatible.

SAFETY PRECAUTIONS

This manual contains important information that ALL users should know and understand BEFORE using this 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:

PROP 65 WARNING

WARNING: This product contains chemicals known to the State of

California to cause

cancer and birth defects or other reproductive harm.

WARNING

Important information to alert you to a situation that might cause serious injury or loss of life if
instructions are not followed.

CAUTION

Important information that tells how to prevent damage to equipment.

NOTE

Information that you should pay special attention to.

WARNING

The following hazards may occur during the normal use of this equipment. Please read the following chart.

HAZARD

CAUSE

SAFEGUARDS

Fire Solvents and coatings can be highly

flammable or combustible, especially
when sprayed.

1. Adequate exhaust must be provided to keep

the air free of accumulations of flammable
vapors.

2. Smoking must never be allowed in the spray
area.

3. Fire extinguishing equipment must be
present in the spray area.

4. Static discharges must be prevented. Ground
(earth) all conductive objects in the spray
area, such as a cleaning solvent bucket, fire
extinguisher, etc.

5. When using solvents for cleaning:

• Those used for equipment flushing must

have a flash point equal to or greater than
that of the coating.

•

Those used for general cleaning must

have flash points above 100°F (37.8°C).

Inhaling Toxic Substances

Certain materials may be harmful if

inhaled or if there is contact with the
skin.

1. Follow the requirements of the Material

Safety Data Sheet supplied by coating
material manufacturer.

2. Adequate exhaust must be provided to keep
the air free of accumulations of toxic
materials.

3. Use a mask or respirator whenever there is a
chance of inhaling sprayed materials. The
mask must be compatible with the material
being sprayed and its concentration.
Equipment must be as prescribed by an
industrial hygienist or safety expert, and be

NIOSH approved.

Explosion Hazard –

Incompatible Materials

Halogenated hydrocarbon Solvents-

for example:
methylene chloride and
1,1,1,-Trichloroethane are not
chemically compatible with the
aluminum that might be used in
many system components. The
chemical reaction caused by these
solvents reacting with aluminum can
become violent and lead to an

equipment explosion.

The AGXV spray gun can be used with these

solvents.
However, aluminum is widely used in other
spray application equipment – such as material
pumps, cups, regulators, valves, etc. Check all
other equipment items before use of these
solvents. Read the label or data sheet for the
material you intend to spray. If in doubt as to
where or not a coating or cleaning material is
compatible, contact your material supplier.

HAZARD

CAUSE

SAFEGUARDS

General Safety

Improper operation or maintenance

may create a hazard.

Operators should be given adequate training in

the safe use and maintenance of the equipment
(in accordance with the requirements of
NFPA-33, Chapter 15 in U.S.). Users must
comply with all local and national codes of
practice and insurance company requirements
governing ventilation, fire precautions, operation,
maintenance and housekeeping (in the U.S.,
these are OSHA Sections 1910.94 and

1910.107 and NFPA-33).

Noise Levels

The continuous A-weighted sound

pressure level of this spray gun may
exceed 85dB(A) depending on the
air cap/nozzle set-up 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.
Details of actual noise levels
produced by the various air
cap/nozzle set-ups are available on

request.

Wear earplugs when using the spray gun.

Spraying solvent

Pressured air/fluid passage may be

broken when cleaning or flashing
with solvent.
The solvent may be harmful if
contacted with eyes.

Always wear eye protection when spraying or

cleaning the equipment.

Misuse:

• All spray guns project particles at high velocity and must never be aimed t any part of body.

• Never exceed the recommended safe working pressure for any of the equipment used.

• The fitting of non-recommended or non-original accessories or spare parts may create hazardous conditions.

• Before dismantling the equipment for cleaning or maintenance, all pressures, air and material, must be isolated and

released.

Disposal of non-metallic materials must be carried out in an approved manner. Burning may generate toxic fumes.

The removal of waste solvents and coating materials should be carried out by an authorized local waste disposal service.

INSTALLATION

Mount the gun with the stud (13) or on a 5/16" dia. rod tightening adequately with the 1/4-28 X 1/4" set screws (Ref. No. 24).
See "ACCESSORIES" for mounting clamps.

by installing a fluid fitting (AGX-415) (order
separately) at recirculating port. See Caution

below.
