Safety precautions
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 HALGOGENATED HYDROCARBON SOLVENTS
which can cause cracks or dissolution on gun body (aluminum) by chemical reaction.
・unsuitable solvents：methyl chloride, dichloromethane, 1.2-dichloroethane,carbon tetrachloride,
（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 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 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
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 spray gun.
Then remove trigger toward 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 ８５ｄＢ(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．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.
-Firmly fix hose or container to spray gun.･･･If not, disconnection of hose and drop of container can cause bodily injury.
Job1. Connect an air hose to air nipple tightly.
Job2. Connect an applicable cup, PCG-6P-M (Option), to fluid nipple tightly.
Job3. Flush the gun fluid passage with a compatible solvent.
Job4. Pour paint into container, test spray and adjust fluid output as well as pattern width.

How to operate
Recommended paint viscosity differs according to paint property and painting conditions
12 to 23 sec./Ford cup#4 is recommendable.
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 100-200mm(3.9~7.9 in) As this gun is operated at low air pressure, high
transfer efficiency will not be obtained if the spray distance is too far.
The gun should be held so that it is perpendicular to the surface of the work piece at all
times. Then, the gun should move in a straight and horizontal line. Arcing the gun
causes uneven painting.
100-200 mm
(3.9-7.9 in)
Pulling the trigger of the gun with the pattern adj. Set and fully opened adjust the air regulator in the spray
booth to obtain 1.0~1.3 bar (14~18 PSI) at the gun inlet as issued on specifications table ahead.
In this way the gun will atomize within 0.7 bar (10 PSI) inside air cap.
NOTE
Using air hose 12m (39.4ft) long, the inner diameter must be a minimum 8 mm (0.315 in) so the gun can
have the correct air volume to atomize at 0.7 bar (10 PSI) inside air cap.

Maintenance
and inspection
-First release air and 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 at the maintenance for protection of the human body.
-Be careful not to damage the tip of fluid nozzle or must not put your hand on it.
-Only an experienced person who is fully conversant with the equipment can do maintenance and inspection.
-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 a fluid nozzle and 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.
2. Clean each section with brush soaked with thinner and wipe out with waste cloth.
3. Before disassembly, fully clean fluid passages. 3. During disassembly, do not scratch seat section.
(1)Disassemble fluid nozzle.
Use ring spanner, box wrench or optional exclusive spanner (code 03538600)
to remove 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..
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-degree) by
spanner.
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.
6. Turn pattern adj. knob or air adj. knob counterclockwise to fully open. And then
tighten pattern adj. set or air adj. set..
Where to inspect Parts replacement standard
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 Replace them if leakage does not stop after fully cleaning fluid nozzle and fluid needle set.
■
Parts list
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 for pressure feed application, please order
nozzle needle set.
Replace if it is crushed or deformed.
Replace if it is deformed or worn out.
If you replace fluid nozzle or fluid needle set only, fully match them and confirm that there is no leakage.
1. Incomplete cleaning can fail pattern shape and uniform particles.
Especially clean fully and promptly two-component paint after use.
2. Soaking whole spray gun in solvent may cause spray gun malfunction. Also soaking air cap
set itself for extended period.
When cleaning, never scratch each hole of air cap set and fluid nozzle, and fluid needle set.
(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 handing tip of fluid needle set since it is sharp.
Disassemble fluid adj. guide set as little as possible.
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 fully loosen it and then tighten it again carefully.
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 lop packing inside fluid adj. guide set will be damaged.
6. If pattern adj. Knob or air adj. Knob is not fully opened, tip of it can contact and damage
fluid nozzle and cause seizure of thread.
