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 by using air hose with built-in ground wire.
Ground wire : Less than 1M.Check the earth stability periodically.
Ifnot, insufficient grounding can cause fire and 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 operating pressureand 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 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 assy and tip of fluid nozzle hasa sharp point.
Do nottouch the tip of fluid needle and the tip of fluid nozzle 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
（
safetyglasses,mask, gloves
）
.
If not, cleaning liquid, etc., can causeinflammation 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 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 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.
・
If you use this spray gun for thefirst time after purchasing, clean fluid passages spraying thinner and remove rust preventive oil.
If not, remaining rust preventive oil can cause painting failure suchas fisheyes.
・
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 airnipple tightly.
Job2. Connect a fluid hose or a container to fluid nipple tightly.
Job3. Flush the spray gun fluid passage with a compatible solvent.
Job4. Pour paint into container, test spray and adjust fluidoutput as well as 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 conversant with the equipment can do maintenance and inspection.
・
U
se neutralcleaner:
pH valueshallbe 6 to 8, otherwise could cause corrosion.
・
Never use commercial or other
partsinstead
of
ANEST IWATA original spare
parts.
Step-by-step procedure
1.
Pour remaining paint to another container. Clean
fluidpassages and
aircapassy
.
Spray a small amount of thinner to clean fluid passages.
1.
Incomplete cleaning can fail pattern shapeand uniform particles.
Especially clean fully and promptly two-component paint after use.
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 defective pattern.
When cleaning, never scratch each hole of air cap assy, fluid nozzle, and fluid needle
assy.
Never damage the tip of fluid nozzleor mustnotput your hand on it.
3. Before disassembly, fully clean fluidpassages.
Remove fluid nozzle, using a ring spanner, box wrench or optional accessory spanner
(code 93538601)
3. Duringdisassembly, do not scratch seatsection.
Either first remove the fluid needle or hold the trigger back while removing the fluid nozzle,
to protect the seating surface.
4.
When you want to adjust fluid needle packing set, first tighten it by hand while
fluid needle
assy remains inserted. Then tighten it further about 1/6 turn (60-degree) by spanner.
When you remove needle packing set, do not leave plastic piece of needle packing set in
thespray gun body.
4.
If you tighten fluid needle packing set too much,
fluid needle assy
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 needleassy.
When you tighten it too much,first fully loosen it and then tighten it againcarefully.
5. To assemble the air valve, first assemble the air valve, air valvespring, and fluid adj. 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 spray gun body set without fluid needle
assy, air valve will not be fitted correctly and lop packing inside fluid adj. guide assy will
be damaged.
6. Before assembling the pattern adj.assy. or air adj.assy. back on to the gun body, 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. knobor airadj.knobis notfully 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 fluidneedletip.
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. Each holepassage of air cap assyand fluidnozzle Replaceif it is crushed or deformed.
2. Packing and O ring Replaceif it is deformed or worn out.
3. Leakage fromseat section between fluid nozzle and fluid needleassy 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
thereisnoleakage.

3. Fully tightenjoint section.
Crescent
1. Paint buildup on air cap assy partiallyclogs horn holes.
Air pressure from both horns differs.
1. Removeobstructions from horn holes with attached brush.
But do not use metal objects to clean horn holes.
Inclined
1. Paint buildup or damage on fluid nozzle circumference and air cap
assycenter.
2. Fluid nozzle is not properly fitted.
1. Removeobstructions.
Replaceif damaged.
2. Remove fluid nozzle and clean seat section.
Split
1. Paint viscosity too low.
2. Fluid output too high.
1. Addpainttoincrease viscosity.
2. Turn fluid adj. knob clockwiseto reduce fluid output.
Or turnpatternadj.assy clockwise.
Heavy Center
1. Paint viscosity is too high.
2. Fluid output is too low.
1. Add thinner to reduceviscosity.
2. Turn fluidadj. knob counter-clockwiseto increasefluidoutput.
Spit
1. Fluid nozzle and fluid needle assy arenot 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 capassy.

How to operate
・
Suggested air pressure is 1.5 to 3.5 bar (22to50 PSI).
・
Recommended paint viscosity differs according to paint property and painting conditions.
14 to 25 sec. / Ford cup#4 is recommendable.
・
Keepfluid output as small as possible to the extent thatthe job will notbe 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 200~250 mm (7.9~9.8 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.
