Instruction Manual ■Electrostatic air hand gun E-M25 series E-M20 series This instruction manual contains Important Warnings, Cautions and instructions for safe operation. Before operation, be sure to read this instruction manual thoroughly and understand the equipment so that you can use it safely and effectively for a long time.
Page 37
Important information ‐ Safety Precautions This electrostatic air hand gun is exclusively used for electrostatic painting ( we call it electrostatic gun from now on ) . Be sure to read and understand this instruction manual. The operator shall be fully conversant with the requirements stated within this instruction manual including important warnings, cautions and operation.
Page 38
Warnings and cautions for safe operation WARNING Fire and Explosion Avoidance of fire and explosion at painting site Never install it at a site with flammable goods or bring flammable goods like lighters. Paints and organic solvents are flammable, able to cause fire. Never use the following Halogenated Hydrocarbon solvents which can chemically react with spray gun parts (aluminum parts) etc., crack and melt them.
Page 39
Avoidance of fire by ignition of paints and solvents Be sure to turn off electric source of electrostatic controller (E-SC12BH : option) or multi-gun controller body of multi-gun controller system(E-MC12 : option) before cleaning inside of fluid passages. As paints and solvents are flammable and have low flash points, they can catch fire if there is spark discharge in and around painting site.
Page 40
Wrong operation Avoidance of wrong use Never point toward human or animal during spraying. If done, it can cause inflammation of eye or skin and bodily injury. Never use gas other than compressed air. If done, it can cause fire or poisoning accident. Never use at higher than max.
Page 41
Protection from solvents, air and fluid pressure Use spray booth and do the painting job in a well-ventilated place. Painting and cleaning jobs in a poorly ventilated site can cause organic solvent poisoning and ignition. Always wear protective tool such as protective goggles and mask. If not, cleaning liquid can touch eyes and skin, causing inflammation.
Page 42
Others Never use altered parts or other than genuine parts when parts are damaged or worn out. If done, it can cause failure of the gun, accidents or bodily injury. Be sure to install a fire extinguisher at painting site. extinguisher Make sure that the equipment has stopped before you enter the working range of other painting equipment (...
