SAFETY WARNINGS
1. Fluid and solvents can be highly flammable or combustible.
- Use in well-ventilated spray booth.
- Avoid any ignition sources such as smoking, open
flames, electrical hazard, etc.
2. NEVER use HALOGENATED HYDROCARBON SOL-
VENTS (1.1.1 T RICHLORINE , ETHYL CHLORIDE , etc.), which can
chemically react with aluminium and zinc parts and cause an explosion. Be sure that all fluids and solvents used are chemically compatible
with aluminium and zinc parts.If in doubt, consult your fluid or solvent supplier to ensure compatibility. Details of materials used in the gun are
available on request.
3. To reduce the risk of static sparking, grounding continuity to the spray equipment and object being sprayed must be maintained.
1. NEVER point gun in the direction of human body.
2. NEVER exceed the maximum safe working pressure of the equipment.
3. ALWAYS release air and fluid pressures before c!eaning, disassembling or servicing. For emergency stop and prevention of unintended opera-
tion, a ball valve installation near the gun to stop air supply is recommended.
1. Toxic vapours produced by spraying certain materials can create intoxication and serious damage to health.
- Use the gun in well-ventilated areas.
- Always wear protective eyewear, gloves, respirator, etc., to prevent the toxic vapour hazard, solvents and paint from coming into contact with
your eyes or skin.
2. Noise level mentioned in main specifications was measured at 1.0 m behind the tip of the gun, 1.6 m height from floor.
- Wear earplugs if required.
1. NEVER enter working areas of robots, reciprocators, conveyors, etc., unless machines are switched off.
2. NEVER spray foods or chemicals through the spray gun.
3. NEVER modify this product for any applications.
INSTALLATION
IMPORTANT:
-This gun should be operated by adequately trained operators only.
- Ensure that the gun has not been damaged during transportation.
- Clean dry air should be supplied to the gun.
1. Fit the gun to a stand or fitting stay, aim at spraying
direction and secure it firmly with fixing bolts.
2. Connect atomizing air hose to atomizing air nipple
(CAP marked side) and operating air hose to opera
ting air nipple (CYL marked side) tightly.
3. Connect fluid hose to fluid nipple tightly.
4. Flush the gun fluid passage with a compatible sol-
vent.
5. Pour paint into container, test spray and adjustfluid
output as well as pattern width.
HOW TO INSTALL HALF UNIONS FORATOMIZING AIR AND OPERATING AIR
1. Remove air nipples for atomizing and operating from gun body.
2. Replace air nipple for atomizing (CAP marked side) with and also replace air nipple operating (CYL marked side ) with half union for
Orifice Diameter 8 mm air tube attached.
3. Be sure to connect half unions to gun body tightly.
HOW TO OPERATE
1. Adjust operating air pressure from 3 to 4 bar.
NOTE:Valve orifice three-way solenoid valve should be minimum
Ø 4 mm and also operating air hose length should be within
10 m with the inner diameter more than Ø 6 mm to avoid delayed operation and any kind of failure.
2. Although atomizing air pressure varies according to spray condition, pulling the piston of the gun with the pattern adj. set fully opened,
adjust it normally 2 to 3 bar.
3. Reccomended paint viscosity differs according to paint property and painting conditions. From 15 to 23 sec. is reccomendable.
4. Using WA 200 spray gun set the spray distance from the gun to the work piece as near as possible within the range of 100
~ 200 mm,
using WA 200 FT
set the spray distance at 100 mm.
NOTE :Using air hose 12 m long. the inner diameter must be a minimum 8 mm so the gun can have the correct air volume.
MAINTENANCE AFTER PAINTING
1) Pour remaining paint into another container and then clean paint passages and air cap. Spray a small amount of thinner to
clean paint passages. Incomplete cleaning will cause adverse pattern shape and particles. Clean fully and promptly two-compo-
nent paint after use.
2) Clean other sections with attached brush soaked with thinner and waste cloth.
3) Clean paint passages fully before disassembly.
4) Remove fluid nozzle after removing fluid needle set or while keeping fluid needle pulled, in order to protect seat
section.
5) While keeping fluid needle set inserted, tighten fluid needle packing set by hand. Then tighten gradually by spanner. Too much
tightening will slow down movement of fluid needle and result in leakage from tip of nozzle.
6) Turn pattern adj. knob counterclockwise to full opening, and then tighten pattern adj. guide into gun body.
