4 308018 W ARNING FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and result in a fire, explosion, or electric shock.
308018 5 W ARNING PRESSURIZED EQUIPMENT HAZARD Spray from the gun, hose leaks, or ruptured components can splash fluid in the eyes or on the skin and cause a serious injury . Do not point the spray gun at anyone or any part of the body . Do not stop or deflect fluid leaks with your hand, body , glove, or rag.
6 308018 Introduction How the Electrostatic Air Spray Gun Works The air hose supplies air to the spray gun. Part of the air operates the turbine and the rest of the air atomizes the fluid being sprayed. The turbine generates power , which is converted by the power cartridge, to supply high voltage current to the gun ’ s ionizing electrode.
