SAFETY WARNINGS

FIRE OR EXPLOSION HAZARD
1. Spark and open flames are strictly prohibited.
Paints can be highly flammable and can cause fire.
Avoid any ignition sources such as smoking, open flames, electrical goods, etc.
2. Never use the following HALGOGENATED HYDROCARBON SOLVENTS
which can cause cracks or dissolution on gun body (aluminum) by chemical reaction.
- UNSUITABLE SOLVENTS: methyl chloride, dichloromethane, 1.2-dichloroethane,
carbon tetrachloride, trichloroethylene, 1.1.1- trichloroethane.
- Be sure that all fluids and solvents are compatible with gun parts.
We are ready to supply a material list used in the product.
3. Securely ground spray gun. Use air hose with built-in ground wire or use grounded gun stay.
Ground resistance : Less than 1MΩ. Check the earth stability periodically.
If not, insufficient grounding can cause fire and explosion due to static electric sparking.
IMPROPER USE OF EQUIPMENT
1. Never point gun towards people or animals.
If done, it can cause inflammation of eyes and skin or bodily injury.
2. Never exceed maximum operating pressure and maximum operating temperature.
3. Be sure to release air and fluid pressure before cleaning, disassembling or servicing.
If not, 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, fluid and thinner to automatic spray
gun. Next, supply 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 of fluid needle during maintenance for the protection of the human body.
PROTECTION OF HUMAN BODY
1. Use in a well-ventilated site by using spray booth.
If not, poor ventilation can cause organic solvent poisoning and catch
fire.
2. Always wear protective gear: safety glasses, mask, gloves.
If not, cleaning liquid, etc., can cause inflammation of eyes and skin.
If you feel something wrong with eyes or skin, immediately see a doctor.
3. Wear earplugs if necessary.
Noise level can exceed 85 dB(A), depending on operating conditions and painting site.
OTHER PRECAUTIONS
1. Never alter this spray gun.
If done, it can cause insufficient performance and failure.
2. Enter working areas of other equipment (robots, reciprocators, etc.) after machines are turned off.
If not, contact with them can cause injury.
3. Never spray foods or chemicals through this gun.
If done, it can cause accident by corrosion of fluid passages or adversely affect health by mixed foreign matter.
4. If something goes wrong, immediately stop operation and find the cause. Do not use again until you have solved the
problem.

TROUBLESHOOTING

Spray Pattern Problems
1. Air enters between fluid nozzle and
Fluttering tapered seat of gun body.
2. Air enters at fluid hose joint
1. Paint buildup on air cap partially
Crescent clogs horn holes. Air pressure from
both horns differs.
1. Paint buildup or damage on fluid nozzle cir-
Inclined cumference and air cap center.
2. Fluid nozzle is not properly fitted.
1. Paint viscosity too low.
Split 2. Fluid output too high.
1. Paint viscosity is too high.
Heavy 2. Fluid output is too low.
Center
1. Fluid nozzle and fluid needle set are
Spit not seated properly.
2. Paint buildup inside air cap set.

Remedies
1. Remove fluid nozzle to clean seat.
If it is damaged, replace nozzle.
2. Fully tighten joint section.
1. Remove obstructions from horn holes.
But do not use metal
objects to clean horn holes.
1. Remove obstructions.
Replace if damaged.
2. Remove fluid nozzle, clean seated section.
1. Add paint to increase viscosity.
2. Tighten fluid adj. knob to reduce fluid output
or reduce air pressure for Fan.
1. Add thinner to reduce viscosity.
2. Turn fluid adj. knob counter-clockwise to
increase fluid output or increase air pressure
for Fan.
1. Clean or replace fluid nozzle and fluid
needle set.
2. Clean air cap set.
