2. SAFETY WARNING
FIRE AND EXPLOSION
1. Never use the following HALOGENATED HYDROCARBON SOLVENTS:
which can cause cracks or dissolution of gun body (aluminium) due to
chemical reaction. UNSUITABLE SOLVENTS: methyl chloride, dichloro-
methane, 1.2-dichloroethane, carbon tetrachloride, trichloroethylene,
1.1.1-trichloroethane
2. Sparks and open flames are strictly prohibited. Paints can be highly
flammable and can cause fire.Do not expose to open flames, electrical
goods, cigarettes etc.
3. Securely ground spray gun using conductive air hose. (Less than 1MΩ)
Always ensure that the spray gun is earthed correctly.
PROTECTION OF HUMAN BODY
1. Use in a well-ventilated site, using a spray booth.
Poor ventilation can cause organic solvent poisoning and fire.
2. Always wear protective gear (safety glasses, mask, gloves) to avoid
inflammation of eyes and skin.
In case of any physical discomfort, immediately seek medical advice.
3. Wear earplugs if necessary.
Noise level can exceed 80 dB(A), depending on operating conditions and
painting site.
4. Pulling the trigger many times during operation, may cause carpal
tunnel syndrome. Always rest, in case of tiredness.
GB
ALWAYS observe WARNINGS and CAUTIONS in this
instruction manual.
1. TECHNICAL SPECIFICATIONS
This ANEST IWATA spray guns kit complies
to ATEX regulations 94/9/EC, protection level:
II 2 G X Suitable for using Zones 1 and 2.
X marking: Any static electricity discharge from the spray gun is to be
diverted to the ground via the conductive air hose as stipulated.
Before use, adjustment or maintenance, it is important
to read this instruction manual very carefully. This ma-
nual must be stored in a safe place for any future reference.
IMPROPER USE
1. Never point gun towards people or animals.
2. Never exceed maximum working pressure or maximum operating
Temperature
3. Always release air and fluid pressure before cleaning, disassembling
or servicing. Otherwise, remaining pressure can cause bodily injury due
to improper operation or scattering of cleaning liquid.
4. Tip of fluid needle set has a sharp point.
Do not touch the tip during maintenance to avoid accidents.
5. Never use this gun to spray foods or chemicals.
Otherwise, foreign substance, could cause corrosion of fluid passages
which could adversely affect health.
6. Never alter this spray gun, to avoid insufficient performance and dam-
age.
7. If something goes wrong, immediately stop operation and find the
cause. Do not use again, until you have solved the problem.
8. Do not enter working areas, where robots, reciprocators, etc. are used,
until they have been turned off. Otherwise, they could cause injury.
3. HOW TO USE
CAUTION
- Use clean air filtered through air dryer and air filter.
- When using this gun for the first time after purchase, adjust fluid nee-
dle packing set (3), spray cleaner to clean fluid passages and remove
rust preventive oil.
- Firmly fix hose or container to spray gun, to avoid disconnection of
hose or container, that can cause bodily injury.
1. Firmly connect an air hose to air nipple 1/4”(4-2).
2. Firmly connect a suitable cup to fluid nipple (4-1).
3. Flush fluid passages with a compatible solvent.
4. Pour paint into container, test spray, adjust fluid output and pattern width.
4. HOW TO OPERATE
_ Suggested atomizing air pressure is 1.5 to 2.5 bar (21 to 36 PSI).
_ Recommended paint viscosity differs according to paint property and
painting conditions. 14 to 25 sec. / Ford cup#4 is recommended.
_ Set the spray distance from the gun to the work piece, as near as possi-
ble within the range of 130-200 mm.
_The gun should be held so that it is perpendicular to the surface of the
workpiece at all times. Then, the gun should move in a straight and hori-
zontal line. Arcing the gun causes uneven painting.
5. MAINTENANCE AND INSPECTION
CAUTION
- Never use spare parts that are not Anest Iwata originals.
- Never damage fluid nozzle tip, fluid needle or air cap holes.
- Never immerse the spray gun completely in liquids such as thinner.

e. Air valve assembly (8), assemble air valve (8), air valve spring (9) and
fluid adj. guide set (10) together. Next, insert fluid needle set (2-2) into
fluid adj. guide set (10), fit it to gun body set (4) and screw fluid adj. gui-
de set (10).
- If you try to fit air valve spring (9) and air valve (8) to gun body set (4)
without fluid needle set (2-2), air valve (8) will not be fitted correctly and
the packing in the fluid adj. guide set (10) will be damaged.
f. Disassembly of pattern adjustment
set (5) and/or air adjustment set (15).
In order to disassemble pattern adj.
set (5) and/or air adj. set (15), first
of all unscrew countersunk socket
head screw Torx T10(C) and remove
adjustment knob (A) by pulling out it
carefully, as illustrated in Fig.1.
Then manually turn the hexagon
knob (D) of the adjustment counterclockwise to open it completely and
unscrew the hexagon face (B) with a spanner turning it counterclockwise.
-To reassemble pattern adjustment set (5) and/or air adjustment set (15),
reverse the procedure.
IMPORTANT: Before reassembling pattern adjustment set and/or air
adjustment set, make sure that these operations are carried out with the
adjustment fully open (Fig.1).
WARNING: When you reinsert the knob
(6) on the adjustment (B) and before to
tighten the countersunk socket screw
(C), make sure that it is pushed in until
it completely covers the face of the
hexagon knob of the adjustment
(Fig.2).
5.4 INSPECTION & REPLACEMENT STANDARD
WHERE TO INSPECT REPLACEMENT PART
a. Each hole passage of air cap (1) Replace if it is crushed or deformed
and fluid nozzle (2-1).
b. Packing and O ring Replace if it is deformed or worn out.
c. Leakage from seat section Replace them if leakage does not
between fluid nozzle (2-1) and stop after fully cleaning fluid nozzle
fluid needle set (2-2). (2-1) and fluid needle set (2-2).
If you replace fluid nozzle (2-1)or
fluid needle set (2-2) only, fully
match them and confirm that there
is no leakage.
GB
- Never soak air cap set (1) in solvent for an extended period, even when
cleaning.
- Never use metal brush to clean the gun.
1. Drain remaining paint from spray gun and cup, into a suitable container.
2. Pour cleaner into cup.
3. Unscrew air cap (1) by 2 turns, to allow atomizing air to back flush, fluid
passages of the gun.
4. Pull trigger (16) and make sure, that atomizing air enters cup.
5. Leave cleaner for a few seconds, then empty it into suitable waste contain-
er.
6. Repeat procedure above, until spray gun is clean.
7. Remove air cap (1) and cup from gun, then clean each section with brush
soaked with cleaner and wipe out with waste cloth.
8. DRY ALL PARTS completely and apply spray gun lubricant to each thread.
5.2 AUTOMATIC CLEANING PROCEDURE
_When using automatic spray gun washer, follow the instruction manual
provided with it. Before cleaning, make sure air is released from air
passages.
_Only use suitable cleaner designed for your spray gun washer.
_ Make sure that the equipment is dried immediately after cleaning.
_Do not leave spray guns inside spray gun washer, after cleaning.
Cleaner vapour can damage packings and cause corrosion inside gun
body.
_Do not leave spray guns soaking in cleaner.
_ Securely ground washer equipment.
Use of cleaner with waterborne coatings, can increase PH level, especial-
ly after several cleanings. Please, replace the cleaner regularly in order to
always ensure the best spray gun performance.
_ Make sure that the PH level of cleaner does not exceed the limit.
PH level: 6.0~8.0 (but only during cleaning).
5.3 DISASSEMBLY PROCEDURE
_Before disassembly, fully clean fluid passages.
a.Disassemble fluid nozzle (2-1), while
keeping fluid needle (2-2) pulled
(triggering) in order to protect its
seat section.
b.Disassemble fluid needle set (2-2).
(only when strictly necessary)
c. Remove fluid adj. knob (13), fluid adj.set (12) and needle spring (11),
extracting the spring and fluid needle set (2-2), from the back of fluid adj.
guide set (10) still assembled on the gun body (4).
d. Fluid needle packing set (3), must
always be adjusted while fluid needle
set (2-2) is inserted and in the follo-
wing way: tighten it by hand (about
a 60 degree turn) and then with
spanner. When you remove needle
packing set (3), do not leave plastic
piece of needle packing set (3) in the
gun body.
- If you tighten fluid needle packing set (3) too much, fluid needle set
(2-2) will not move smoothly, resulting in paint leakage from tip of fluid
nozzle (2-1).
-Try to adjust it carefully while pulling trigger and confirming movement
of fluid needle set (2-2).
- If you tighten it too much, repeat operation.
