How to operate
Suggested air pressure is 3.0 to 3.5 bar (43 to 50 PSI).
Recommended paint viscosity differs according to paint property
and painting conditions. 15 to 23 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 150
－
200 mm (5.9
－
7.9 in).
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.

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
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.
3. Before disassembly, fully clean fluid passages.
3. During disassembly, do not scratch seat section.
(1)Disassemble fluid nozzle.
Use an attached spanner to remove fluid nozzle.
(1)Remove fluid nozzle after removing fluid needle set or while keeping fluid needle pulled, in
order to protect seat section.
4. To adjust fluid needle packing set, while keeping fluid needle set inserted, tighten fluid
needle packing seat by spanner.
4. If you tighten fluid needle packing set too much, fluid needle set 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 set.
When you tighten it too much, first fully loosen it and then tighten it again carefully.
5. Turn air adj. knob counterclockwise to fully open. And then tighten air adj. set.
5.If 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.
