Safety precautions
Fire and explosion
1.
Spark and open flames are strictly prohibited.
Paintscan 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.
unsuitablesolvents
：
methyl chloride, dichloromethane, 1.2-dichloroethane,carbon tetrachloride, trichloroethylene, 1.1.1-trichloroethane
(Be sure that allfluids andsolvents are compatible with spray gun parts. We are ready to supplya material list used in the product)
3. Securely ground spray gun byusing air hose with built-in ground wire.
Ground wire should haveless than 1M resistant. Periodically check the ground for continuity.
Insufficient grounding can cause fire or explosion due to static electric sparking.
Improper use of equipment
1.
Never point
spraygun
toward people or animal.
If done, it can cause inflammation of eyes and skin or bodily injury.
2. Never exceed maximum operatingpressure or temperature.
3. Be sure to release air and fluid pressuresbefore 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 thespray is pointed in a safe direction.
4. Tip of fluid needle and tip offluid nozzlehas a sharp point.
Avoid touching the tip of the fluid needle or fluidnozzle 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
（
safetyglasses,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 earplugsif necessary.
Noise level can exceed 80dB(A), depending on operatingconditions and painting site
4
．
If operators pull the trigger many times during use, 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. Only enter the working areasofother equipment (robots, reciprocators,etc.) after machines have safely been shutdown.
If not, contact with them can causeinjury.
3. Never spray foods or chemicals through this spraygun.
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 airfiltered through air dryer and air filter. If not, dirty air can cause painting failure.
・
Beforeusing the spray gun for the first time, clean fluid passages with thinner to removerustpreventive oil.
If notcleaned, the rust preventive oil can cause paint failure, such as fish eyes.
・
Firmly connect hose or cup to spray gun. If not, disconnection of hose or drop of cup can cause bodily injury .
Step1. Connect an air hose to airnipple tightly.
Step2. Connect a fluid hose or a container to fluid nipple tightly.
Step3. Flush the spray gun fluid passage with a compatible solvent.
Step4. Pour paint into container, test spray and adjust fluid output as wellas pattern width.
■ Maintenance and inspection
・
First release air and pressure fully according to item No.3 of “Improper useof equipment” of WARNING on page 2.
・
Only an experienced person who is fully knowledgeable of the equipment should perform maintenance and inspection.
・
U
se neutralcleaner:
pH valueshallbe 6 to 8, otherwise could cause corrosion.
・
Only use genuine ANEST
IWATA parts for any maintenance or repairs.
Step-by-step procedure
1.
Pour remaining paint to another container. Clean fluid passages and
aircap assy
.
Spray a small amount of thinner into fluidpassages to clean them.
1.
Incompletecleaningcan resultin
poorspray patternandcontaminated paint.
It is especially important clean the gun fully and promptly after using two-component paint.
2.
Clean each section withbrush soaked with thinner and wipe out with waste cloth.
2.
Soaking whole spray gun in solvent may cause spray gun malfunction.
Also soaking air
cap assy. itself for extended period may cause a defective spray pattern.
When cleaning, never scratch the air cap assy., fluid nozzle, or fluid needle.
Avoid touching or damaging the tipof the fluid nozzle or needle.
3. Before disassembly, fully clean fluid passages.
Remove fluid nozzle, using a ring spanner, box wrench or optional accessory spanner
(code 93538601)
3. Duringdisassembly, avoid scratching the needleseatingsurface.
Either first remove the fluid needle or hold the trigger back while removing the fluid nozzle,
to protect the seating surface.
4.
If you need to adjust fluid needle packing set, first tighten it by hand (with fluid needle in
place). Then tighten it further about1/6 turn (60-degree) by spanner.
When you remove needle packing set, do not leave the plastic tip of the packing in the
spray gun body.
4.
If you tighten the fluid needle packing set too much, fluid needle will not move
smoothly,
resulting in paint leakage from tip of the fluid nozzle. Try to adjust it carefully while pulling
thetrigger and confirming smooth movement of the fluid needle.
If you tighten it too much, first fully loosen it andthen retighten again carefully.
5. To assemble the airvalve, first assemblethe airvalve, air valve spring, andfluidadj. guide
assy. together. Next, insert fluid needle into fluid adj. guide assy., then fit it to spray gun
body and screwfluid adj. guide assy. in.
5.
If you try to fit
air valve spring and air valve to the spray gun body without the fluid
needle, the air valve may not be fitted correctly and the packing inside fluid adj. guide
assy. can be damaged.
6. Before assembling the pattern adj.assy. or air adj. assy.back on to the gunbody, fully turn
the adjustment knobs counterclockwise to open. Once in the gun body the pattern adj.
knob and air adj. knob can be tightened.
6. If pattern adj. knob or air adj. knob is not fully opened when tightening into gun body,the tip
of it can contact and damage the seating surface.
7. When you assemble the needle spring on the fluid needle, the plastic tip should be on the
opposite sideas the fluid needle tip.
7. If plastic tip is on the wrong side, it may not operate normally. Incorrect installation of the
needle spring may cause a heavy triggerpull.
Where to inspect
Parts replacement standard
1. Eachhole passage of air cap assy and fluid nozzle Replaceif it is crushed or deformed.
2. Packing and O ring Replaceif it is deformed or worn out.
3. Leakage from seatingsurface between fluid nozzle and fluid needle Replacethem if leakage does not stop after fully cleaning the fluid nozzle and needle.
If you replace the fluid nozzle or fluid needle only, ensure they fully match and confirm that
thereisno leakage.

2. Fluid output too high.
3. Pattern airpressure is too high.
1. Add paint to increase viscosity.
2. Turn fluidadj. knob clockwise to reduce fluid output.
3. Turn pattern adj. assy. clockwiseto reduce pattern air pressure.
Heavy Center
1. Paint viscosity is too high.
2. Fluid output is too low.
1. Add thinner to reduceviscosity.
2. Turnfluid adj.knob counter-clockwiseto increasefluidoutput.
Spit
1. Fluid nozzle andfluid needle are not seated properly.
2. The first-stagetravel of trigger (when only air discharges) decreases.
3. Paint buildup inside air cap assy.
1. Clean or replace fluid nozzle and fluid needle assy..
2. Replacefluid nozzleand fluidneedle assy.
3. Clean air cap assy.

■ How to operate
・
Suggested air pressure is 1.0 to 2.5 bar (14.5 to 36.3 PSI).
Too high air pressure may cause of unstable fluid outlet.
・
Recommended paint viscosity differs according to paint property and painting conditions.
14 to 25 sec. / Ford cup#4 is recommendable.
・
Keep fluid output assmall as possible to the extent that the job will not be hindered.
It will lead to better finishing with fine atomization.
・
Set the spraydistance from the spray gun to the work piece as near as possible within the range of 150~200 mm (5.9~7.9 in).
・
The spray gun should be held so that it is perpendicular to the surface of the work piece at all times.
Then, the spray gun should move in a straight and horizontal line. Arcing the spray gun causes uneven painting.
