SAFETY PRECAUTIONSThis 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 andportions 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.
HAZARDCAUSESAFEGUARDS

Fire

Solvents and coatings can be highly 1. Adequate exhaust must be provided to keep
flammable or combustible, especiallythe air free of accumulations of flammablewhen sprayed.
vapors.
2. Smoking must never be allowed in the sprayarea.
3. Fire extinguishing equipment must bepresent in the spray area.
4. Static discharges must be prevented.
Ground(earth) all conductive objects in thespray area, such as a cleaning solvent
bucket, fire extinguisher, etc.
5. When using solvents for cleaning:• Those used for equipment flushing musthave a flash point equal to or greater thanthat of the coating.
• Those used for general cleaning musthave flash points above 100°F (37.8°C).

Inhaling Toxic Substances

Certain materials may be harmful if
inhaled or if there is contact with theskin.

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 achance of inhaling sprayed materials. The
mask must be compatible with the material
being sprayed and its concentration.
Equipment must be as prescribed by anindustrial hygienist or safety expert, and be
NIOSH approved.

Explosion Hazard –Incompatible Materials

Halogenated hydrocarbon Solventsfor example:
methylene chloride and1,1,1,-Trichloroethane are notchemically compatible with thealuminum that might be used inmany system components. The
chemical reaction caused by thesesolvents reacting with aluminum canbecome violent and lead to an
equipment explosion.

The T-AGB spray gun can be used with thesesolvents.
However, aluminum is widely used in otherspray application equipment – such as material
pumps, cups, regulators, valves, etc. Check allother equipment items before use of thesesolvents. Read the label or data sheet for thematerial you intend to spray. If in doubt as towhere or not a coating or cleaning material iscompatible, contact your material supplier.

HAZARDCAUSE

SAFEGUARDS

General Safety

Improper operation or maintenancemay create a hazard.

Operators should be given adequate training inthe safe use and maintenance of the equipment(in accordance with the requirements of
NFPA-33, Chapter 15 in U.S.). Users mustcomply with all local and national codes ofpractice and insurance company requirements
governing ventilation, fire precautions, operation,
maintenance and housekeeping (in the U.S.,
these are OSHA Sections 1910.94 and1910.107 and NFPA-33).

Noise Levels

The continuous A-weighted soundWear 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 animpulse sound level meter andanalyzer, 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 flashingwith 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 andreleased.
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.

Figure 2. Installation

Mount the gun with the stud (21) or tighten with M8 (F) of the gun body.
NOTE
The air supplied to the gun should be clean air that removed any impurities. Also, the air hose should have enough innerdiameter depending on the length to supply necessary air. As CYL air is not consumption air, large diameter of the tube is notnecessary. 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 Adjusting Screw (20) counter-clockwise 3.5 turns from fully closed position and fix with Lock Nut (19).
This makes the Needle fully opened.
4. Adjust CAP/FAN air at 0.20Mpa.
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 atsource 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 thecleaning 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.
