■ How to operate
Recommended paint viscosity differs according to paint property and
painting conditions. 12 to 20 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 gun to the work piece as near as
possible within the range of 50-150mm(2~5.9 in) As this gun is
operated at low air pressure, high transfer efficiency will not be obtained
if the spray distance is too far.
■ 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 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. Do not immerse the whole gun in thinner. If done, it can damage parts.
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. (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.
You do not need to remove fluid adj. guide set from gun body. Remove fluid adj. knob
and fluid needle spring, and then pull out fluid needle spring, and then pull out fluid
needle set from back of fluid adj. guide set..
(2) Be careful when handing tip of fluid needle set since it is sharp.
Disassemble fluid adj. guide set as little as possible.
4.To adjust fluid needle packing set, while keeping fluid needle set inserted, tighten fluid
needle packing seat by hand and then tighten further by spanner.
4.Too much tightening of fluid needle packing set can cause bad movement of fluid needle set
and fluid leakage from the tip of fluid needle set..
5.In order to assemble air valve, first assemble air valve & air valve spring & fluid adj.
guide set together. Next, insert fluid needle set into fluid adj. guide set , then fit it to
gun body set and screw fluid adj. guide set.
5. If you try to fit air valve spring and air valve to gun body set without fluid needle set, air
valve will not be fitted correctly and lop packing inside fluid adj. guide set will be
damaged.
6.Turn pattern adj. knob or air adj. knob counterclockwise to fully open. And then
tighten pattern adj. set or air adj. set..
6. If pattern adj. Knob or air adj. Knob is not fully opened, tip of it can contact and damage
fluid nozzle and cause seizure of thread.
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.
■ Parts list
When ordering parts, specify gun’s model, part name with ref. No. and marked No. of air cap
set, fluid nozzle and fluid needle.
When replacing fluid nozzle or/and fluid needle for pressure feed
application, please order nozzle needle set.
The gun should be held so that it is perpendicular to the surface of the work piece at all times. Then, the
gun should move in a straight and horizontal line. Arcing the gun causes uneven painting.

Fluid nozzle-fluid needle set combination
Pulling the trigger of the gun with the pattern adj. Set and fully opened adjust the air regulator in the spray
booth to obtain 0.5~1.0 bar ( 7~14 PSI) at the gun inlet as issued on specifications table ahead.
In this way the gun will atomize within 0.7 bar (10 PSI) inside air cap.
NOTE
Using air hose 12m(39.4ft) long, the inner diameter must be a minimum 8 mm (0.315 in) so the gun can
have the correct air volume to atomize at 0.7 bar (10 PSI) inside air cap.
