How to operate

Recommended paint viscosity differs according to paint property and painting conditions

12 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 100-200mm(3.9~7.9 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 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 03538600)

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.

(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. When you want to adjust fluid needle packing set, first tighten it by hand while fluid

needle set remains inserted. Then tighten it further about 1/6 turn (60-degree) 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. 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.

Pulling the trigger of the gun with the pattern adj. Set and fully opened adjust the air regulator in the spray

booth to obtain 1.0~1.3 bar (14~18 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.
