The direction of the fan spray (horizontal or vertical) is obtained by turning the air nozzle to the desired position, then tightening the air cap/retaining ring. Tighten only finger tight. Do not use pliers or wrench to tighten or loosen. llOfH2QNTAL FAN VERTICAL FAN FIGURE 2 5 CONTROLLING THEFLUID If a fluid pressure tank is used, the amount of fluid can be controlled by regulating the pressure on the tank. The amount of fluid can also be controlled by means of the fluid needle adjusting screw. By turning it clockwise (to the right), the amount of fluid is reduced. Turning it counterclockwise (to the left) increases the amount of fluid. HINTS FOR GOOD SPRAYING TECHNIQUES At all times hold the spray gun perpendiculartothesurface being sprayed. A spraying distance of 6-8 inches is recommended. This distance can be varied depending on the item being sprayed, the material or the air pressure used. Release the trigger at the end of each lateral stroke while the gun is still traveling. Start the gun moving at the beginning of the next stroke so the gun is in motion when the trigger is pressed (see illustration). This action should be practiced until a smooth, steady, rhythmic stroke becomes natural. SURFACE EggggssBssgsssssgg I 1 I STMT **£JS hoik** mmol* mnt —I—1 ■ILCiX nuecc« Overlap each stroke 50%. This is done by aiming the gun at the edge of the last stroke. A short practice period will be necessary to achieve an even stroke. Avoid arching the gun as this will leave an uneven coat of paint (see illustration). To Clean Gun: Spray a small amount of clean solvent through the gun. Never immerse the gun in solvents as this removes lubricants and dries out the packings. A caustic solution should not be used to clean gun, as this will destroy the aluminum alloy. Remove air nozzle and wash it In solvent. If necessary to clean air nozzle holes, use a broom straw or toothpick. Never use a steel wire or hard instrument as this will result in distortion of spray pattern. Wipe exterior of gun with solventsoaked cloth. Neversoak gun in liquid detergent. To Lubricate gun: After each day's use place a drop of oil at trigger screw, fan control packing, and fluid needle packing. Occasionally remove fan control spring and recoat with a light grease or Vaseline. MAINTENANCE Proper adjustment of your Craftsman Detail Touch-Up Gun will give you a normal spray pattern of this shape (see illustration). If not, consult service check liston next page. NOTE: If water is used as a solvent, clean the gun, and spray paint thinner or mineral spirits through the gun after cleaning to remove any excess moisture and protect parts. ROUND FAN DQMT ARC csssssmsssgs» ABCI NC MOTION CLEANING AND PREVENTIVE MAINTENANCE Preventive maintenance should head off some problems commonly encountered. Remember your detail touch-up gun is precision engineered and proper maintenance can help you get the fine quality results you desire. 6 TROUBLESHOOTING GUIDE PROBLEM CAUSE CORRECTION Heavy top or bottom pattern. ^ ^ Heavy right or left side pattern. ^ ^ Material build-up on air cap or fluid tip. Partially plugged horn holes, center holes or fluid tip hole. Determine where material build-up is by inverting cap and test spraying. If pattern shape stays in same position, the condition is caused by material build-up on fluid tip. If pattern changes with cap movement, the condition is in the air cap. Soak cap or tip in suitable solvent and wipe clean. To clean orifices use a broom straw or toothpick. Never use a wire or hard instrument. This damages holes and distorts its spray pattern. Heavy center pattern. Too much material Material too thick. Reduce fluid flow or increase air pressure. Thin material. Split spray pattern. ^ Not enough material. Reduce air pressure or increase fluid flow. Jerky or fluttering spray. Insufficient material. Gun with cup tipped at excessive angle. Obstructed fluid passage or hose. Loose fluid tip. (Most common cause.) Loose or cracked fluid tube in cup or pressure tank. Dry or worn packing or loose packing nut. Fill material container. Do not tip excessively or rotate fluid tube. Clean. Tighten to stop leak. Tighten or replace. Lubricate or replace. Tighten. Improper spray pattern. Gun improperly adjusted. Dirty air cap. Fluid tip obstructed. Sluggish needle. Readjust gun following instructions carefully. Clean air cap. Clean. Lubricate. Unable to get round spray. Fan adjustment stem not seating properly. Clean or replace. Will not spray. No air pressure at gun. Needle adjusting screw not open enough. Check air lines. Open needle adjusting screw. Fluid leakage from packing retainer nut. Packing nut loose. Packing worn or dry. Tighten, but not so tight as to grip needle. Replace packing or lubricate. See "Maintenance". 7 TROUBLESHOOTING GUIDE (Cont'd) PROBLEM CAUSE CORRECTION Dripping from fluid tip. Dry packing.
