SAFTEY PRECAUSTIONS
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 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 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
℃
).
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 a
n 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 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 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.
MISUES:
・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
authorised local waste disposal service.

INSTALLATION
Figure 1. Dimensions
Figure 2.Air Circuit Example
Mounting 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 manufacture’s instructions.
2. Adjust the CYL air at 0.34~0.49 Mpa.
3. Turn theAdjusting 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 the Fluid pressure at 0.07~0.1Mpa.
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 feed tank. Carefully follow instructions in bulletin sent with tank.
2. Replace material in container with a suitable solvent.
3. Repressurize system.
4. Trigger gun and repeat procedure until gun and hose are thoroughly clean. A SolventSaverTM 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 SolventSaverTM. 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.
