Maintenance and inspection
・
First release air and 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 at the maintenance for protection of the human body.
・
Be careful not to damage the tip of fluid nozzle or must not put your hand on it.
・
Only an experienced person who is fully conversant with the equipment can do maintenance and inspection.
-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 may cause defective pattern.
-Never damage holes of air cap a fluid nozzle and fluid needle.
Step-by-step procedure
Important
1. Pour remaining paint to another container. Clean fluid passages and air cap set..
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 set
itself for extended period.
When cleaning, never scratch each hole of air cap set and fluid nozzle, and fluid needle set.
3. Before disassembly, fully clean fluid passages.
3. During disassembly, do not scratch seat section.
(1)Disassemble fluid nozzle.
Use ring spanner, box wrench or optional exclusive spanner (code No.035386000)
to disassemble fluid nozzle.
(1)Remove fluid nozzle after removing fluid needle set or while keeping fluid needle pulled,
in order to protect seat section.
(2)Disassemble fluid needle set.
Remove fluid adj. set and pull out fluid needle set from gun body.
Pay attention so that spring does not suddenly fly out since fluid adj. set is strongly pushed by
fluid needle spring and piston spring.
(2)Pull fluid needle set after loosening fluid needle packing set to protect fluid needle packing set.
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.
Spray Pattern
Problems
Remedies
Fluttering
1. Air enters between fluid nozzle and tapered seat of gun body.
2. Air enters at fluid hose joint.
1. Remove fluid nozzle to clean seat.
Ｉ
f it is damaged, replace nozzle.
2. Fully tighten joint section.
Crescent
1. Paint buildup on air cap partially clogs horn holes.
Air pressure from both horns differs.
1. Please remove obstacles adhering to the horn holes with resin brush
But do not use metal objects to clean horn holes.
Ｉ
nclined
1. Paint buildup or damage on fluid nozzle circumference and air cap center.
2. Fluid nozzle is not properly fitted.
1. Remove obstructions. Replace if damaged.
2. Remove fluid nozzle and clean seat section.
Split
1. Paint viscosity too low.
2. Fluid output too high.
1. Add paint to increase viscosity.
2. Tighten fluid adj. knob to reduce fluid output. Lower the Fan air.
Heavy Center
1. Paint viscosity is too high.
2. Fluid output is too low.
1. Add thinner to reduce viscosity.
2. Turn fluid adj. valve knob counter-clockwise to increase fluid output.
Spit
1. Fluid nozzle and fluid needle set are not seated properly.
2. Paint buildup inside air cap set.
1. Clean or replace fluid nozzle and fluid needle set.
2. Clean air cap set.
