! WARNING Use a face mask/respirator and protective clothing when spraying. Always spray in a well ventilated area to prevent health and fire hazards. Refer to Material Safety Data Sheets (MSDS) of spray material for details. ! DANGER Never spray closer than 25 feet to the compressor! If possible, locate compressor in separate room. Never spray into the compressor, compressor controls or the motor. 3. Do not smoke or eat when spraying paint, insecticides, or other flammable substances. ! WARNING Do not spray flammable materials in vicinity of open flame or near ignition sources. Motors, electrical equipment and controls can cause electrical arcs that will ignite a flammable gas or vapor. Never store flammable liquids or gases in the vicinity of the compressor. Do not misuse this ! WARNING product. Excessive exposure to vibration, work in awkward positions, and repetitive work motions can cause injury to hands and arms. Stop using any tool if discomfort, numbness, tingling or pain occur, and consult a physician. 4. When spraying and cleaning, always follow the instructions and safety precautions provided by the material manufacturer (Refer to MSDS). Do not spray acids, ! WARNING corrosive materials, toxic chemicals, fertilizers or pesticides. Using these materials could result in death or serious injury. 5. Keep visitors away and NEVER allow children or pets in the work area. Never aim or ! WARNING spray at yourself or anyone else or serious injury could occur. 6. Always work in a clean environment. To avoid injury and damage to the workpiece, do not aim the spray gun at any dust or debris. REMINDER: Keep your dated proof © 2004 IN285700AV 3/04 28 Sp Operating Instructions and Parts Manual General Safety Information ! WARNING Do not use pressure that exceeds the operating pressure of any of the parts (hoses, fittings, etc.) in the painting system. Keep hose away ! CAUTION from sharp objects. Bursting air hoses may cause injury. Examine air hoses regularly and replace if damaged. 7. Always use a pressure regulator on the air supply to the spray gun. Failure to install NOTICE appropriate water/oil removal equipment may result in damage to machinery or workpiece. Introduction The spray gun is a vital link in any finishing application. In addition to operating the spray gun properly, techniques of surface preparation and paint preparation must be understood. These instructions will explain the differences among various spray technologies and serve as a guide in the proper operation and techniques of spray painting. Refer to the Replacement Parts Manual for model specific information. SPRAY GUN TERMS Atomization - Conversion of bulk liquid to spray droplets (mist) . Bleeder – In this mode, air passes con tinuously through the gun whether spraying or not. This mode is generally used when the air is supplied by a continuously running compressor that does not have a tank. Bleeder/Non-Bleeder – Indicates whether air flows through the gun continuously or as the trigger is pulled. External Mix – Process where the air and paint are mixed just after leaving the nozzle. This type of mix should be used for fast drying paints and when a high quality finish is needed. Feed – Method used to bring paint into the gun for spraying. Fluid Control Knob – Used to control the amount of paint being mixed with air. HVLP Gravity Feed Spray Gun Gravity Feed – Method of paint feed similar to the siphon feed method. However, the cup is inverted to create a positive fluid pressure at the nozzle. Internal Mix – Process where the air and paint are mixed inside the air cap just before being sprayed. This method is best for heavy bodied, slow drying paints and can only be used with the pressure feed method. Do not use fast drying paints with internal mix. The paint will dry inside and quickly clog the air cap. Mix – The mixing of paint and air when spraying. Non-Bleeder – In this mode, air flows only when the trigger is pulled. This type of operation is used with a compressor equipped with a tank or with a large factory air system. Paint Tank – An auxiliary pressurized paint reservoir that allows continuous spraying of large amounts of paint without stopping for refills as with a canister. It also allows using the spray gun at any angle without causing paint to drip. Pattern Control Knob – Used to form the proper pattern (size and shape) of paint as it is sprayed from the gun to the workpiece. Pressure Feed – Method of paint feed where a canister or paint tank is pressurized to force paint to the gun. Either internal or external mix air caps are used with this method. Pressure feed is generally used for spraying heavy bodied paints or for large size projects. Siphon Feed – Method of paint feed where atmospheric pressure creates a partial vacuum to siphon paint to the gun. Only external mix air caps are used with this method. Siphon feed is used with light bodied paints. Viscosity – A measurement of the resistance to the flow of liquids. CONVEN...
