Safety precautions
Fire and explosion
1.
Spark and open flames are strictly prohibited.
Paintscan be highly flammable and cancause fire.
Avoid anyignition sources such as smoking, open flames, electricalgoods, etc.
2. Never use the following HALOGENATED HYDROCARBON SOLVENTS
which can causecracks 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 surethat all fluids and solvents arecompatible with spray 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 should have less 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 pointspray gun toward people oranimal.
If done, it cancause inflammation of eyes and skin or bodily injury.
2. Never exceed maximum operating pressure or temperature.
3. Be sure to release air and fluid pressures before cleaning, disassembling or servicing.
If not, remaining pressure can cause bodily injury or property damage.
To releasepressure, firstshut off the supply of compressed air and fluid to the spray gun.
Then squeeze trigger, while thespray is pointedin a safe direction.
4. Tip of fluid needle and tip of fluid nozzle has a sharp point.
Avoidtouching the tip of the fluid needle or fluidnozzle during maintenance to prevent injury.
Protection of human body
1
．
Use only in a well
-
ventilatedarea (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 causeirritation of eyes and skin.
If you feel something wrong with eyes or skin, immediately see a doctor.
3
．
Wear earplugsifnecessary.
Noise level can exceed 80dB(A), dependingon operating conditions and painting site
4
．
If operators pull the trigger many times duringuse, 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 cancause insufficient performance and failure.
2. Only enter the working areas of other equipment (robots, reciprocators,etc.) after machines have safely beenshut down.
If not, contact with them can cause injury.
3. Never spray foods or chemicals through this spraygun.
If done, it cancause accident by corrosion of fluid passages or adversely affect healthby mixed foreign matter.
4. If something goes wrong,immediately stop operation and find the cause. Do notuse 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.
・
Before using the spray gun for the first time, clean fluid passages with thinner to removerust preventive oil.
If not cleaned, 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 dropof cup can cause bodily injury ..
Step1. Connect an air hose to air nipple 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, testspray and adjust fluid output as well as pattern width.
■ Maintenance and inspection
・
Firstrelease air and pressure fully according to item No. 3 of “Improperuseof equipment” ofWARNING on page 2.
・
Only an experienced person who is fully knowledgeable of the equipment should perform maintenance and inspection.
・
U
se neutral cleaner:
pH valueshall be 6 to 8, otherwise could cause corrosion.
・
Only usegenuineANEST IWATA parts for any maintenance or repairs.
Step-by-step procedure
1.
Pour remaining paint to another container. Clean fluidpassages and
aircapassy
.
Spray a smallamount of thinner into fluid passages to clean them.
1.
Incomplete cleaningcanresult in poorspray pattern andcontaminated 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 forextended 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 tip of the fluid nozzle or needle.
3. Before disassembly,fully clean fluidpassages.
Remove fluid nozzle, using a ring spanner, box wrench or optional accessory spanner
(code 93538601)
3. Duringdisassembly,avoid scratchingtheneedleseating surface.
Either first remove the fluid needle or hold the trigger backwhile 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 about 1/6turn (60-degree) by spanner.
When you remove needle packing set, do not leave the plastic tip of the packing in the
spray gunbody.
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 fluidneedle.
If you tighten it too much, first fully loosen it and then retighten again carefully.
5. To assemble the air valve, first assemble the air valve, air valve spring, 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 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.
knoband airadj. knob can be tightened.
6. If pattern adj. knob or air adj.knobis not fully opened when tightening into gun body, thetip
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 sideasthefluid needletip.
7. If plastic tip is on the wrong side, it may not operate normally.Incorrectinstallation of the
needle spring may cause a heavy trigger pull.
Where to inspect
Parts replacement standard
1. Each holepassage of air cap assyand fluid nozzle Replaceif it is crushed or deformed.
2. Packing and O ring Replaceif it is deformed or worn out.
3. Leakage from seating surface between fluid nozzle and fluid needle Replacethemif 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
there isno leakage.

Replaceifdamaged.
2. Remove fluid nozzle and clean seat section.
Split
1. Paint viscosity too low.
2. Fluid output too high.
1. Add paintto increaseviscosity.
2. Turn fluidadj. knob clockwise to reducefluid output.
Or turnpattern adj.assy clockwise.
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 increase fluidoutput.
Spit
1. Fluid nozzle and fluid needle assy are not seated properly.
2. The first-stage travel of trigger (when only air discharges)decreases.
3. Paint buildup inside aircap assy.
1. Clean or replace fluid nozzleand fluid needle assy.

■ How to operate
・
Suggested air pressure is 1.5 to 3.5 bar (22to 50 PSI).
・
Recommended paint viscosity differs according to paint property and painting conditions.
14 to 25 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 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 sothat 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.
