Safety precautions
Fire and explosion
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 HALOGENATED HYDROCARBON SOLVENTS
which can cause cracks or dissolution on spray 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 spray gun parts. We are ready to supply a material list used in the product)
3.
Ground spray gun securely.
Use a grounded gun stay. Ground resistance: Less than 1MΩ. Check the stability of grounding condition periodically.
If not, insufficient grounding can cause fire and explosion due to static electric sparking.
Improper use of equipment
1. Never point spray gun toward people or animal.
If done, it can cause inflammation of eyes and skin or bodily injury.
2. Never exceed maximum operating pressure or temperature.
3. Be sure to release air and fluid pressures before cleaning, disassembling or servicing.
If not, remaining pressure can cause bodily injury or property damage.
To release pressure, first shut off the supply of compressed air and fluid to the spray gun.
Then squeeze trigger, while the spray is pointed in a safe direction.
4. Tip of fluid needle and tip of fluid nozzle has sharp point.
Avoid touching the tip of the fluid needle or fluid nozzle during maintenance to prevent injury.
Protection of human body
1 ． Use only in a well-ventilated area (such as in a spray booth).
If not, poor ventilation can cause organic solvent poisoning and fire hazard.
2 ． Always wear protective gear （safety glasses, mask, gloves）.
If not, paint, solvents, etc., can cause irritation of eyes and skin.
If you feel something wrong with eyes or skin, immediately see a doctor.
Wear earplugs if necessary.
3 ．
Noise level can exceed 80dB(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. Only enter the working areas of other equipment (robots, reciprocators, etc.) after machines have safely been shut down.
If not, contact with them can cause injury.
3. Never spray foods or chemicals through this spray gun.
If done, it can cause accident by corrosion of fluid passages or adversely affect health by mixed foreign matter.
If something goes wrong, immediately stop operation and find the cause. Do not use again until you have solved the problem.
4.
How to connect
The effective cross-section of three-way solenoid valve must be φ4 or more.
Narrow air passages or a longer air hose between three-way solenoid valve and gun can cause delay in start and stop operations of the spray gun.
Atomizing air hose must have an inner dia. of φ6 or more, and the length must be 10 m or less.
Adjustment of timing for ON and OFF for atomizing, fan, and operating must be conducted in the following order.
For start spraying (timing of turn ON each air): ① Atomizing air
For stop spraying (timing of turn OFF each air): ① Operating air
If ON/OFF timing is improper, it causes failure of painting finish owing to spit of paint.
Attach the automatic gun to manifold firmly. Automatic gun may may fall, resulting in injury to the human body.
Use clean air passed through air dryer and air filter. ・・・ If not, dirty air can cause painting failure.
Before using the spray gun for the first time, clean fluid passages with thinner to remove rust preventive oil.
If not cleaned, the rust preventive oil can cause paint failure, such as fish eyes.
② Fan air ③ Operating air
② Fan air ③ Atomizing air
