How to operate
Suggested air pressure of 2.5 to 3.5 bar (36 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 within the range of 150
－
200 mm (6
－
8 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 assy 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 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. Do not immerse the whole gun in thinner. If done, it can damage parts.
When cleaning, never scratch each hole of air cap assy and fluid nozzle, and fluid needle
assy.
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 assy or while keeping fluid needle pulled,
in order to protect seat section.
4. To adjust fluid needle packing assy, while keeping fluid needle assy inserted, tighten
fluid needle packing seat by hand and then tighten further by spanner.
4. Too much tightening of fluid needle packing assy can cause bad movement of fluid needle
assy and fluid leakage from the tip of fluid needle assy.
5. Turn pattern adj. knob or air adj. knob counterclockwise to fully open. And then
tighten pattern adj. assy or air adj. assy.
5. 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 assy
Replace them if leakage does not stop after fully cleaning fluid nozzle and fluid needle assy.
If you replace fluid nozzle or fluid needle assy only, fully match them and confirm that there is
no leakage.
