Safety precautions
1. Spark and open flames are strictly prohibited.
Paints can be highly flammable and can cause fire.
Avoid any ignition sources such as smoking, open flames, electrical goods, etc.
2. Never use the following HALGOGENATED HYDROCARBON SOLVENTS
which can cause cracks or dissolution on gun body (aluminum) by chemical
reaction.
3. Securely ground spray gun.
Use air hose with built-in ground wire or use grounded gun stay.
Ground resistance : Less than
１
M
Ω
.
Check the earth stability periodically.
If not, insufficient grounding can cause fire and
explosion due to static electric sparking.
・
unsuitable solvents
：
methyl chloride, dichloromethane,1.2-dichloroethane,carbon tetrachloride, , trichloroethylene, 1.1.1-trichloroethane
（
Be sure that all fluids and solvents are compatible with gun parts. We are ready to supply a material list used in the product
）
1. Never point gun toward people or animal.
If done, it can cause inflammation of eyes and
skin or bodily injury.
2. Never exceed maximum operating pressure
and
maximum operating Temperature.
3. Be sure to release air and fluid pressures before cleaning,
disassembling or servicing.
If not, remaining pressure can cause bodily injury due to improper
operation or scattering cleaning liquid.
In order to release pressure, first stop supply of compressed air, fluid and
thinner to automatic spray gun.
Next, supply only piston operating air and exhaust fluid by operating fluid
needle, which results in automatic supply stop of all compressed air.
4. Tip of fluid needle set has a sharp point. .
Do not touch the tip of needle valve at the maintenance for the protection
of the human body.
Protection of human body
1
．
Use in a well-ventilated site by using spray booth.
If not, poor ventilation can cause organic solvent poisoning and catch fire.
2
．
Always wear protective gear
（
safety glasses, mask, gloves
）
.
If not, cleaning liquid, etc., can cause inflammation of eyes and skin.
If you feel something wrong with eyes or skin, immediately see a doctor.
3
．
Wear earplugs if necessary.
Noise level can exceed
８０ｄＢ
(A), depending on operating conditions and painting site
Other precautions
1
．
Never alter this spray gun.
If done, it can cause insufficient performance and failure.
2
．
Enter working areas of other equipment (robots, reciprocators, etc.) after
machines are turned off. If not, contact with them can cause injury.
3
．
Never spray foods or chemicals through this gun.
If done, it can cause accident by corrosion of fluid passages or adversely
affect health by mixed foreign matter.
4
．
If something goes wrong, immediately stop operation and find the
cause. Do not use again until you have solved the problem.

How to connect
-
Use clean air filtered through air dryer and air filter.
・・・
If not, dirty air can cause painting failure.
-
If you use this gun for the first time after purchasing, clean fluid passages spraying thinner and remove rust preventive oil.
If not, remaining preventive oil can cause painting failure such as fish eyes.
-
Use three-way solenoid valve of more than
φ
4 inner dia. cross-sectional area and air hose of over
φ
6 inner dia. and less than 10m length.
If not, small dia. of solenoid valve and longer air hose between three-way solenoid valve and gun can cause delay in operation.
-
Firmly fix hose to spray gun.
･･･
If not, disconnection of hose and drop of container can cause bodily injury.
Job1. Fit the gun on a stand or fitting stay, aim at spraying direction and secure it firmly
with fixing bolts.
Job2. Connect atomizing air hose to atomizing air inlet (Cap marked side) and fan air
hose to fan air inlet (FAN marked side) tightly.
And then connect operating air hose to operating air hose to operating air inlet
(CYL marked side) tightly.
Job3. Connect fluid hose to fluid inlet tightly.
Job4. Supply thinner to automatic gun. Spray and clean fluid passage with thinner.
Job5. Supply paint to automatic gun and test spray and adjust air volume, fluid output and
pattern width as necessary.
