T-AGHV HVLP
COMPACT AUTO GUN Operation Manual
Important:Read and follow all instructions and SAFETY PRECAUTIONS before using this equipment.
DESCRIPTION
T-AGHV gun a small, light-weight HVLP compact auto gun and suitable for robots and automatic machines.
This gun is designed to obtain high transfer efficiency with maximum 0.07Mpa (10psi) air cap pressure for all combinations.
The actual air cap pressure can be measured with Air Cap Test Gauge (optional).
Models and application information follows.

(Min. 500cc/min)
Actual pattern is determined depending on the orifice size of fluid tip, delivery, atomizing air pressure and pattern air pressure.
It is recommended to use 33A Air Cap, which most paint can be atomized with and consumes less air and better transfer
efficiency than 46MP Air Cap.
However, for paint which is difficult to be atomized such as high solid paint or medium delivery of 300~500cc/min, 46MP Air
Cap is recommended. Also, 83MP Air Cap is suitable for high delivery of over 500cc/min.
The air passage of this gun is made of Stainless Steel and may be used with chlorinated solvents. 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:
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 1. Adequate exhaust must be provided to keep
flammable or combustible, especially
the air free of accumulations of flammable
when sprayed.
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 Solventsfor 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 T-AGB 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
Wear earplugs when using the spray gun.
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.
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
Figure 1. Dimensions
Figure 2. Installation
Mount the gun with the stud (21) or tighten with M8(F) of the gun body.
CAUTION:
The air supplied to the gun should be clean air that removed any impurities. Also, the air hose should have enough inner
diameter depending on the length to supply necessary air.
As CYL air is not consumption air, large diameter of the tube is not necessary.
When circulating the paint, remove the plug and install the fluid nipple.

OPERATION
1. Mix, prepare and strain the coating material to be sprayed according to paint manufacturer’s instructions.
2. Adjust the CYL air at 0.34~0.49Mpa.
3. Turn the Adjusting Screw (20) counter-clockwise 3.5 turns from fully closed position and fixed with Lock Nut (19).
This makes the Needle fully opened.
4. Adjust the CAP/FAN air at about 0.35Mpa.
5. Adjust fluid air at about 0.07Mpa~0.1Mpa.
6. Turn on CYL air and test spray. Adjust fluid and air pressure until desired pattern is obtained. Control fluid pressure at
source supply. Always attempt to keep CAP pressure as low as possible to minimize overspray.
WARNING
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 pressure tank. Carefully follow instructions in bulletin sent with tank.
2. Replace material in container with a suitable solvent.
3. Re-pressurize system.
4. Trigger gun and repeat procedure until gun and hose are thoroughly clean. A SolventSaver™ type hose and gun cleaner
which supplies a mixture of air and solvent can be used to most effectively clean gun and hose internal passages. See
“Accessories” for SolventSaver™. Wipe exterior of gun with a solvent dampened cloth.
5. If a recirculating system is used, it may be necessary to fit a shut off valve in return line to ensure fluid tip and forward
portion of sprayhead passage are properly cleaned when flushed with solvent.
CAUTION
Do not totally submerge gun in solvent. It is possible to wash solids into air operating sections of gun which could seriously
damage piston “O” Ring seals.
CAUTION
The air cap can be immersed in solvent for cleaning. If orifices are clogged, use a broom straw or toothpick to remove
obstruction. Never use a steel wire or hard instrument. This will damage air cap and result in a distorted spray pattern.
