MAINTENANCE AND INSPECTION
Step-by-step procedure
Important
1. Clean fluid passages and air cap set.
1. Incomplete cleaning can fail pattern shape and uniform particles.
Spray a small amount of thinner to clean fluid passages.
Especially clean fully and promptly after use with two-component paint.
2. Clean each section with brush soaked with thinner and wipe out with waste cloth.
2. Do not immerse the whole gun in thinner. If done, it can damage parts.
When cleaning, never scratch any holes of air cap set, of fluid nozzle,
or fluid needle set.
3. Before disassembly, fully clean fluid passages.
3. During disassembly, do not scratch seat section.
(1) Disassemble fluid nozzle.
(1) Remove fluid nozzle after removing fluid needle set or while keeping

needle packing set.
Pay attention so that spring does not suddenly fly out since fluid adj. set is strongly
pushed by fluid needle spring and piston spring.
Where to inspect
Parts replacement standard
1. Each hole passage of air cap 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 set.
Replace them if leakage does not stop after fully cleaning fluid nozzle and
fluid needle set. If you replace fluid nozzle or fluid needle set only,
fully match them and confirm that there is no leakage.

WARNING
- First release air and fluid 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 during maintenance for protection of
the human body.
- Be careful not to damage the tip of the fluid nozzle or not put your hand on it.
- Only an experienced person who is fully conversant with the equipment can do maintenance and inspection.
CAUTION
- Never use commercial or other parts instead of ANEST IWATA original spare parts.
- Never immerse the whole gun into liquid such as thinner.
- Never soak air cap set in solvent for extended period even if cleaning. It can cause defective pattern.
- Never damage holes of air cap, fluid nozzle or fluid needle.
HOW TO OPERATE
Adjust operating air pressure from 3 to 4 bar (43 to 57 PSI).
Air pressure for atomizing or fan, varies according to spray conditions, adjust as specified on above specifications table.
NOTE:
Valve orifice inside two-way or three- way solenoid valve should be minimum 4mm (0.157 in) and also operating air hose
length should be within 10m (32.8ft) with the inner diameter more than 6mm (0.236in) to avoid delayed operation and any kind of
failure.
NOTE:
Using air hose 12 m (39.4 ft) long, the inner diameter should be minimum 8mm (0.315 in) in order to have the correct air
volume to atomize.
Recommended paint viscosity differs according to paint property and painting conditions.
Set the spray distance from the gun to the work piece as near as possible within the range of 100-150 mm ( 3.9-5.9 in).
CIRCULATION FITTING EXAMLPE
HOW TO CHANGE UNIONS FOR CIRCULATION USAGE
IMPORTANT
1. Remove hexagon nut from gun body with 5 mm allen wrench.
2. Pull plug out from gun body, with attached screw as standard accessory.
3. Connect fitting joint tightly to another FLU marked side.
4. Connect fluid hose to the joint.
