WA-M220, WA-220L Automatic Spray Gun
Before use, adjustment or maintenance, it is important
to read this instruction manual very carefully.
This manual must be stored in a safe place for any future
reference.
This ANEST IWATA automatic spray guns complies
to ATEX regulations 2014/34/EU.
Protection level: II 2G 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.
ALWAYS observe WARNINGS and CAUTIONS in this
instruction manual.

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, dichloromethane,
1.2-dichloroethane, carbon tetrachloride, trichloroethylene, 1.1.1-trichloroe-
thane.
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 than1MΩ)
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 85 dB(A), depending on operating conditions and
painting site.
IMPROPER USE
1. Never point gun towards people or animals.
2. Never exceed maximum working pressure or maximum operating

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. In order to release pressure,
first stop supply of compressed air and fluid to automatic spray gun. Next, sup-
ply only piston operating air and exhaust fluid by operating fluid needle, which
results in automatic supply stop of all compressed air.
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 sub-
stance, could cause corrosion of fluid passages which could adversely affect
health.
6. Never alter this spray gun, to avoid insufficient performance and damage.
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 CONNECT

CAUTION:
(Use WA-M220 only with manifold WA-M4R)
- Use clean air filtered through air dryer and air filter.
- When using this automatic gun for the first time after purchase, spray
cleaner to clean fluid passages and remove rust preventive oil.
- Use three-way solenoid valve of more than ø 4 inner dia. cross-sectional
area and air hose of over ø 6 inner dia. and less than 10m length. Small
dia. of solenoid valve and longer air hose between three-way solenoid
valve and gun can cause delay in operation.
- Firmly fix hose to spray gun, to avoid that the disconnection of hose
during operation, can cause bodily injury.
1. Connect the gun to the manifold (12) by tightening wing bolt (9) then fit the
manifold (12) to fitting stay, aim at spraying direction and fix it by fixing bolt.
2. Connect atomizing air hose to atomizing air inlet (CAP marked side)
fan air hose to fan air inlet (FAN marked side) and operating air hose to oper-
ating air inlet (CYL marked side) tightly.
3. Connect fluid hose to fluid inlet (FLU marked side) tightly. In case of circulation
usage, connect fluid hose to fluid outlet (CIR marked side) tightly, too. In the
case of not usage with circulation system, fix tightly the plug (ref.17 as stand-
ard accessory) on CIR marked side orifice.
4. Flush the gun fluid passages with a compatible cleaner.
5. Supply paint, test spray and adjust fluid output, air volume and pattern
width.
