SAFETY WARNINGS

1. Sparks 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 (aluminium) by chemical reaction.          
- Unsuitable solvents: methyl chloride, dichloromethane, 1.2-dichloroethane,carbon tetra-
chloride,  trichloroethylene, 1.1.1-trichloroethane                          
- Be sure that all fluids and solvents are compatible with gun parts.  
We can supply a list of materials used to manufacture the product. 

3. Securely ground spray gun.

Use air hose with built-in ground wire or use grounded gun stay.

Ground resistance : Less than 1M

.

Check the earth stability periodically.           

If not, insufficient grounding can cause fire and explosion due to static electric sparking.

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 pressures 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 spray gun. Then remove fluid adj. knob and
pull fluid needle set towards you.

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.

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

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 have been 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.
