Fire and explosion
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 HALOGENATED HYDROCARBON SOLVENTS
which can cause cracks or dissolution on spray gun body (aluminum) by chemical reaction.
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 spray gun parts. We are ready to supply a material list used in the product)
3. Ground spray gun securely.
Use grounded gun stay. Ground resistance : Less than １MΩ. Check the earth stability periodically.
If not, insufficient grounding can cause fire and explosion due to static electric sparking.
Improper use of equipment
1.
Never point spray
gun toward people or animal.
If done, it can cause inflammation of eyes and skin or
bodily injury.
2. Never exceed maximum operating pressure or temperature.
3. Be sure to release air and fluid pressures before cleaning,
disassembling or servicing.
If not, remaining pressure can cause bodily injury or property damage.
To release pressure, first shut off the supply of compressed air and fluid to the spray gun.
Then squeeze trigger, while the spray is pointed in a safe direction.
4. Tip of fluid needle and tip of fluid nozzle has a sharp point.
Avoid touching the tip of the fluid needle or fluid nozzle during maintenance to prevent injury.
Protection of human body
1．Use only in a well-ventilated area
(such as in a spray booth).
If not, poor ventilation can cause organic solvent poisoning
and fire hazard.
2．Always wear protective gear （safety glasses, mask, gloves）.
If not, paint, solvents, etc., can cause irritation 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. Only enter the working areas of other equipment (robots, reciprocators, etc.) after machines have safely been shut down.
If not, contact with them can cause injury.
3. Never spray foods or chemicals through this spray 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
Step1
Fit the gun to fitting stay, aim at spraying direction and fix it.
Step2
Connect atomizing air hose to atomizing air side (Cap marked side) and operating air hose to operating air side( CYL marked side).
Step3
Connect fluid hose to fluid inlet side.
Step4
supply thinner to automatic gun. Spray and clean fluid passage with thinner.
Step5
supply paint to automatic gun and test spray and adjust air volume, fluid output and pattern width as necessary.
Maintenance and inspection
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 φ4 inner dia. cross-sectional area and air hose of overφ6 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.

First release air and pressure fully according to item No. 3 of “Improper use of equipment” of WARNING on page 2.
Only an experienced person who is fully knowledgeable of the equipment should perform maintenance and inspection.
Use neutral cleaner: pH value shall be 6 to 8, otherwise could cause corrosion.

Only use genuine ANEST IWATA parts for any maintenance or repairs.

How to operate
Step1
Adjust operating air pressure from 3 to 4 bar (43 to 57 PSI).
NOTE: Valve orifice inside three- way solenoid valve should be minimumφ4mm (0.157 in) and also operating air
hose length should be within 10m (32.8ft) with the inner diameter more than φ6mm 0.236in) to avoid delayed
operation and any kind of failure.
Step2
Although atomizing air pressure varies according to spray conditions, pulling the piston of the gun with the pattern
adj. set fully opened, adjust it normally 3 to 4 bar (43 to 57 PSI) with WIDER1A / WIDER1A-05R / WIDER2A.
Step3
Recommended paint viscosity differs according to paint property and painting conditions. 15 to 23 sec/Ford cup#4.
is recommendable.
Step4
Set the spray distance from the gun to the work piece as near as possible within the range of 150〜200 mm (5.9
to 7.9 in) with WIDER1A / WIDER1A-05R, 200〜250 mm (7.9 to 9.8 in) with WIDER2A.
Where to inspect Parts replacement standard
1
Eachholepassage ofaircapandfluidnozzle
Replace if it is crushed or
