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 solventsmethyl 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 fluid adj. knob and pull fluid needle set 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
1Use in a well-ventilated site by using spray booth.
If not, poor ventilation can cause organic solvent poisoning and catch fire.
2Always 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
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
1Never 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.
4If 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.
-When you use this gun for the first time after purchasing, adjust fluid needle packing set.
Slowly tighten fluid packing seat and loosen a bit when fluid needle set does not return smoothly, and adjust so that fluid needle set smoothly moves.
-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.
Job1. Connect an air hose to air nipple tightly. Job2. Connect an applicable cup 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
・・・
If not, disconnection of hose and drop of container can cause bodily injury.

How to operate
Recommended paint vis cos ity di ffers acco rdin g to pai nt proper ty and painting conditions. 12 to 20 sec ./Ford cu p#4 is rec om menda ble.
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 50- 150m m( 2~5.9 in) As this gun is operated at low air pressur e, high tra nsfer effici ency wil l not be obtai ned
if the spray distanc e is too far .
Maintenance
Pulling the trigger of the gun wi th the patter n adj. S et and ful ly ope ned adj ust th e air regul ator in the spr ay booth to obtain 0.5~1.0 bar ( 7~14 PSI) at the gun inl et as i ss ued on sp ecif ica tions table ah ead. In this way the gun will atomi ze withi n 0.7 bar (10 P SI) insi de air cap.
NOTE
Using air hose 12m(39.4ft) long , the inne r diam eter mus t be a m inim um 8 mm (0.31 5 in) s o the gun can have the correct air volume to atomize at 0.7 bar (10 PSI) inside air cap.
and inspection
The gun should be held so that it i s pe rpendi cul ar to the sur face of the wo rk piece at all ti m es. Th en, the gun should move i n a s tr ai gh t an d hor iz on tal lin e. A r c i ng the g un c a us e s u ne v en p ain ti ng.
-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 damage holes of air cap a fluid nozzle and fluid needle.
Step-by-step procedure
1.Pour remaining paint to an other contain er. Clean fluid passages and air cap set.. Spray a small amount of thinner to clean fl uid pass age s.
2.Clean each section with brus h soak ed wi th thinne r and wi pe out with waste c loth.
3. Before disassembly, fully clean fluid passages. 3. During disassembly, do not scratch seat section. (1)Disassemble flui d noz zle.
(2)Disassemble flui d needl e 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. gui de se t..
4.To adjust fluid needle packing set, while keeping fluid needle set inserted, tighten fluid needle packing seat by ha nd and then ti ghten fu rther by s panner .
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 ad j. guid e set.
6.Turn pattern adj. knob or air adj. knob counterclockwise to fully open. And then
tighten pattern adj. set or air adj. s et..
Where to inspect Parts replacem ent s tandar d

3.Leakage from seat section between fluid nozzle and fluid needle set Replace them if leakage does not s top after ful ly cle aning fluid nozzle and fluid needle set.
Parts list
When ordering parts, spec ify gun’ s m odel , part nam e with r ef. No. and mar ke d No. of air c ap set, fluid nozzle and fluid needle. When replacing fluid noz zle or /and fl uid ne edle fo r pres su re fe ed application, please order noz zle ne edle s et.
1. Incomplete cleaning can fail patter n sha pe and uni form par ticl es. Especially cl ean full y an d prom ptly two- com pone nt paint a fter use .
2. Do not immerse the whole gun in thinner. If done, it can damage parts.
When cleaning, never sc ratch eac h hole of air c ap set an d fluid nozzl e, and fl uid need le 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 nee dle s et sinc e it is sha rp.
Disassemble fluid adj. guide s et as littl e as pos si ble.
4.Too much tightening of fluid needle packing set can cause bad mo ve me n t of flu i d n e ed l e se t and fluid leakage from the ti p of flui d need le s et..
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 s eizu re of th read.
Replace if it is crushed or deformed. Replace if it is deform ed o r worn out.
If you replace fluid nozzle or fluid needle set only, fully match them and confirm that there is no leakage.
