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 spray gun for the first time after purchasing, clean fluid passages spraying thinner and remove rust preventive oil.
If not, remaining rust 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 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 fluid output as well as pattern width.

Never use commercial or otherparts instead of ANEST IWATA original spare parts.
Step-by-step procedure
1. Pour remaining paint to another container. Clean fluid passages andair cap assy.
Spray a small amount of thinner to clean fluid passages.
1. Incomplete cleaning can fail pattern shape and uniform particles.
Especially clean fully and promptly two-component paint after use.
2. Clean each section with brush 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 nozzle or must not put your hand on it.
3. Before disassembly, fully clean fluid passages.
Remove fluid nozzle, using a ring spanner, box wrench or optional accessory spanner
(code 93538601)
3. During disassembly, do not scratch seat section.
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
the spray 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 needle assy.
When you tighten it too much, first fully loosen it and then tighten it 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 screw fluid 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. 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 side as 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 trigger pull.
Where to inspect Parts replacement standard
1. Each hole passage of air cap assy and fluid nozzle Replace if it is crushed or deformed.
2. Packing and O ring Replace if it is deformed or worn out.
3. Leakage from seat section between fluid nozzle and fluid needle assy
Replace them 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
there is no leakage.
