2 In this part sheet, the words WARNING, CAUTION and NOTE are used to emphasize important safety information as follows:!! CAUTION NOTE WARNING Hazards or unsafe practices which could result in severe personal injury, death or substantial property damage. Hazards or unsafe practices which could result in minor personal injury, product or property damage.! WARNING Read the following warnings before using this equipment. Important installation, operation or maintenance information. READ THE MANUAL Before operating finishing equipment, read and understand all safety, operation and maintenance information provided in the operation manual. INSPECT THE EQUIPMENT DAILY Inspect the equipment for worn or broken parts on a daily basis. Do not operate the equipment if you are uncertain about its condition. WEAR SAFETY GLASSES Failure to wear safety glasses with side shields could result in serious eye injury or blindness. NEVER MODIFY THE EQUIPMENT Do not modify the equipment unless the manufacturer provides written approval. DE-ENERGIZE, DISCONNECT AND LOCK OUT ALL POWER SOURCES DURING MAINTENANCE Failure to De-energize, disconnect and lock out all power supplies before performing equipment maintenance could cause serious injury or death. KNOW WHERE AND HOW TO SHUT OFF THE EQUIPMENT IN CASE OF AN EMERGENCY OPERATOR TRAINING All personnel must be trained before operating finishing equipment. PRESSURE RELIEF PROCEDURE Always follow the pressure relief procedure in the equipment instruction manual. EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equip ment to rupture, malfunction, or start unexpectedly and result in serious injury. NOISE HAZARD You may be injured by loud noise. Hearing protection may be required when using this equipment. KEEP EQUIPMENT GUARDS IN PLACE Do not operate the equipment if the safety devices have been removed. PROJECTILE HAZARD You may be injured by venting liquids or gases that are released under pressure, or flying debris. PINCH POINT HAZARD Moving parts can crush and cut. Pinch points are basically any areas where there are moving parts. STATIC CHARGE may develop a static charge that must be dissipated through proper grounding of the equipment, objects to be sprayed and all other electrically conductive objects in the dispensing area. Improper grounding or sparks can cause a hazardous condition and result in fire, explosion or electric shock and other serious injury. FIRE AND EXPLOSION HAZARD Never use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in equipment with aluminum wetted parts. Such use could result in a serious chemical reaction, with the possibility of explosion. Consult your fluid suppliers to ensure that the fluids being used are compatible with aluminum parts. AUTOMATIC EQUIPMENT Automatic equipment may start suddenly without warning. CA PROP 65 PROP 65 WARNING WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO THE OPERATOR OF THE EQUIPMENT. 2 FOR FURTHER SAFETY INFORMATION REGARDING BINKS AND DEVILBISS EQUIPMENT, SEE THE GENERAL EQUIPMENT SAFETY BOOKLET ( ).

3 Binks Model 21 (BRASS BODY) Automatic Spray Gun Hook-Up 1. Air pressure of PSI minimum required for cylinder operation. 2. For rapid operation, the air line between three-way valve and the cylinder operating air connection should be as short as possible. 3. All air supplied to the gun should be dirt and moisturefree. An oil and water extractor mounted in the air supply line is recommended. 4. If the gun is to stand idle for any length of time, shut off. This will prevent small leaks throughout the system from turning on the gun. Fan Spray Adjustments The fan spray is easily controlled by means of the side port control stem, (22). Turning this control to the right, or clockwise, will give a round spray pattern. Turning it to the left, or counter-clockwise, will widen the spray into a fan shape of any desired width. Orientation of the fan spray either horizontally or vertically (or to any position in between) is obtained by loosening the retainer ring, rotating the air nozzle to the desired position, and then tightening the retainer ring. FLUID FLOW adjustments For best results, the fluid control screw (18) should be set at the open position and the flow of the fluid controlled by regulating the fluid pressure in the pressure tank. If the conditions under which the gun is being used require the fluid to be controlled at the gun, it may be accomplished by loosening locknut (19) and turning screw (18) to the right (clockwise) to decrease the flow of fluid or the left (counter-clockwise) to increase the flow of fluid. Lubrication The points that require lubrication on this gun are the plunger (7), the air valve packing (11), and the fluid packing (36). These parts should be kept soft and pliable at all times. A light machine oil is recommended for this lubrication.! Caution Never submerge the gun in solvent. Solvent will wash the oil off the lubricated parts and cause subsequent malfunctioning of the gun. Cleaning Shut off the air supply to the tank and release its pressure. Hold a piece of wadded cloth over the gun nozzle and turn on the air to the cylinder. The air will back up through the fluid nozzle and force fluid out of the hose and into the tank. Replace the paint in the pressure tank with clean solvent and spray the solvent through the gun until it is clean. Dry out the residual solvent in the fluid hose by blowing air through it. Faulty Spray Faulty spray is caused by dry coating material residue around the fluid nozzle tip or inside the air nozzle. Soak these parts in a solvent that will soften the dried residue until it can be removed with a brush or a cloth.! Caution Never use metal probes to clean the air or fluid nozzles because scratches and burns on their precision machined surfaces can cause faulty spray. If either the air or fluid nozzle is damaged so as to give faulty spray, it must be replaced.
