WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. D Ground the equipment. D If there is any static sparking or you feel an electric shock while using this equipment, stop spraying immediately. Do not use the equipment until you identify and correct the problem. D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid being sprayed. D When flammable liquid is sprayed or used for flushing or cleaning the equipment, the turbine must be placed at least 20 feet (6.1 m) away from areas where hazardous concentrations of flammable vapors are likely to occur. D Use additional air hose if necessary to ensure that the turbine is operated in a clean, dry, well ventilated area. D Never place the turbine inside a spray booth! Use this equipment outdoors or in extremely well ventilated areas. D Keep the spray area free of debris, including solvent, rags, and gasoline. D Electrically disconnect all equipment in the spray area. D Extinguish all open flames or pilot lights in the spray area. D Do not smoke in the spray area. D Do not turn on or off any light switch in the spray area while operating or if fumes are present. D Do not operate a gasoline engine in the spray area. 2 308-810 WARNING EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury. INSTRUCTIONS D This equipment is for professional use only. D Read all instruction manuals, tags, and labels before operating the equipment. D Use the equipment only for its intended purpose. If you are not sure, call your distributor. D Do not alter or modify this equipment. Use only genuine Graco parts and accessories. D Check equipment daily. Repair or replace worn or damaged parts immediately. D Do not exceed the maximum working pressure of the lowest rated system component. See the Technical Data on page 23. D Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Technical Data on page 23 for this information. D Do not use hoses to pull equipment. D Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not ex- pose Graco hoses to temperatures above 82_C (180_F) or below –40_C (–40_F). D Wear hearing protection when operating this equipment. D Do not lift pressurized equipment. D Comply with all applicable local, state, and national fire, electrical, and safety regulations. D Do not point the gun at anyone or at any part of the body. D Follow the Pressure Relief Procedure on page 11 if the fluid nozzle clogs and before cleaning, checking or servicing the equipment. D Tighten all fluid connections before operating the equipment. D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. D Know the specific hazards of the fluid you are using. D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines. D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer. D Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in the turbine spray system, which contains aluminum and/or galvanized-coated parts. Such use could result in a serious chemical reaction, with the possibility of explosion, which could cause death, serious injury, and/or substantial property damage. 308-810 3 Setup Information 2.
