SAFETY WARNINGS
FIRE OR EXPLOSION HAZARD
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 (aluminium) 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 gun parts.
We are ready to supply a material list used in the product.
3. Securely ground spray gun by using air hose with built-in ground wire.
Ground wire : Less than 1M Ω 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 gun towards people or animals.
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 of cleaning liquid.
In order to release pressure, first stop supply of compressed air, fluid and thinner to spray gun. Then remove fluid adj. knob and pull fluid needle set towards you.
4. Tip of fluid needle set has a sharp point.
Do not touch the tip of fluid needle during 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 85 dB(A), depending on operating conditions and painting site
4. If operators pull the trigger many times during operation, it may cause carpal tunnel syndrome.
Be sure to take a rest if you feel tired.
OTHER PRECAUTIONS
1. Never alter this spray gun.
If done, it can cause insufficient performance and failure.
2
2. Enter working areas of other equipment (robots, reciprocators, etc.) after machines are turned off.
If not, contact with them can cause injury.

OTHER PRECAUTIONS
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
CAUTION
- Use clean air filtered through air dryer and air filter. If not, dirty air can cause painting failure.
- When 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.
- Firmly fix hose to spray gun. If not, disconnection of hose can cause bodily injury.
1. Connect an air hose to air nipple tightly.
2. Connect a twin fluid hose (hoses for circulation) to fluid nipples tightly. (See fig.)
3. Flush the gun fluid passage with a compatible solvent.
4. Pour paint into container, test spray and adjust fluid output as well as pattern width.
G 1/4” B NPSM 1/4”
HOW TO OPERATE
Suggested air pressure is 2.0 to 3.5 bar (29 to 50 PSI).
Recommended paint viscosity differs according to paint property and painting conditions. 15 to 23 sec. / Ford cup#4 is recommendable.
150-200 mm
5.9-7.9 in
Keep fluid output as small as possible to the extent that the job will not be hindered. It will lead to better finishing with fine atomization.
Set the spray distance from the gun to the work piece as near as possible within the range of 150_200 mm (5.9_7.9 in).
The gun should be held so that it is perpendicular to the surface of the workpiece at all times. Then, the gun should move in a straight and horizontal line. Arcing the gun causes uneven painting.
Marked parts are wearable parts.
NOTE: When ordering parts, specify gun’s model, part name with ref.No. and marked
No.of air cap set, fluid nozzle and fluid needle.When replacing fluid nozzle or/and fluid needle, please order nozzle needle set.

MAINTENANCE AND INSPECTION
WARNING
- First release air and fluid pressure fully according to item No. 3 of “Improper use of equipment” of WARNING on page 2.
- Tip of fluid needle set has a sharp point. Do not touch the tip of needle valve duirng maintenance for protection of the human body.
- Be careful not to damage the tip of the fluid nozzle or put your hand on it.
- Only an experienced person who is fully conversant with the equipment can do maintenance and inspection.
CAUTION
- Never use commercial or other parts instead of ANEST IWATA original spare parts.
- Never immerse the whole gun into liquid such as thinner.
- Never soak air cap set in solvent for extended period even if cleaning. It may cause defective pattern.
- Never damage holes of air cap fluid nozzle or fluid needle.
Step-by-step procedure
1.Pour remaining paint to another container. Clean fluid passages and air cap set.
Spray a small amount of thinner to clean fluid passages.
Important
1. Incomplete cleaning can fail pattern shape and uniform particles.
Especially clean fully and promptly after use with two-component paint.
2.Clean each section with brush soaked with thinner and wipe out with waste cloth.
2. Do not immerse the whole gun in thinner. If done, it can damage parts.
When cleaning, never scratch any holes of air cap set and fluid nozzle, and fluid needle set.
3. Before disassembly, fully clean fluid passages.
(1) Disassemble fluid nozzle.
(2) Disassemble fluid needle set.
You do not need to remove fluid adj. guide set from gun body.
Remove fluid adj. knob and fluid needle spring, and then pull out fluid needle spring, and then pull out fluid needle set from back of fluid adj. guide set.
3. During disassembly, do not scratch seat section.
(1) Remove fluid nozzle after removing fluid needle set or while keeping fluid needle pulled, in order to protect seat section.
(2) Be careful when handling tip of fluid needle set since it is sharp.
Disassemble fluid adj. guide set as little as possible.
4.When you want to adjust fluid needle packing set, first tighten it by hand while fluid needle set remains inserted. Then tighten it further about 1/6 turn (60-degrees) by spanner. When you remove needle packing set, do not leave plastic piece of needle packing set in the gun body.
plastic piece
(white)
4. If you tighten fluid needle packing set too much, fluid needle set will not move smoothly, resulting in paint leakage from tip of fluid nozzle. Try to adjust it carefully while pulling trigger and confirming movement of fluid needle set. When you tighten it too much, first loosen it and then tighten it again carefully.

5.In order to assemble air valve, first assemble air valve & air valve spring
& fluid adj. guide set together. Next, insert fluid needle set into fluid adj. guide set, then fit it to gun body set and screw fluid adj. guide set.
5. If you try to fit air valve spring and air valve to gun body set without fluid needle set, air valve will not be fitted correctly and packing inside fluid adj. guide set will be damaged.
6 .Turn pattern adj. knob or air adj. knob counterclockwise to fully open.
And then tighten pattern adj. set or air adj. set.
6. If pattern adj.Knob or air adj. Knob are not fully opened, tip of it can contact and damage fluid nozzle and cause seizure of thread.
Where to inspect
1. Each hole passage of air cap and fluid nozzle
2. Packing and O ring
3. Leakage from seat section between fluid nozzle and fluid needle set
Parts replacement standard
Replace if it is crushed or deformed.
Replace if it is deformed or worn out.
Replace them if leakage does not stop after fully cleaning fluid nozzle and fluid needle set. If you replace fluid nozzle or fluid needle set only, fully match them and confirm that there is no leakage.
TROUBLESHOOTING
Spray Pattern Problems
Fluttering
1. Air enters between fluid nozzle and tapered seat of gun body.
2. Air is drawn from fluid needle packing set
3. Air enters at fluid hose joint.
Remedies
1. Remove fluid nozzle to clean seat.
If it is damaged, replace nozzle.
2. Tighten fluid needle packing.
3. Fully tighten joint section.
