APPLICATION SPRAYER

"INTERNAL MIX" PRESSURE FEED

      Spray gun designed for fast application of practically all types of paint materials. The air and paint are mixed inside the nozzle so this gun is an "INTERNAL MIX" type. Air pressure in the paint cup forces paint through the liquid tube to the nozzle, marking this "PRESSURE FEED" gun.

BLEEDER TYPE

      Since this gun is designed primarily for use with portable air compressors that operate continuously during the spraying process, there is no air value on the gun. The air flows through the nozzle continuously so the gun is known as a "BLEEDER TYPE."

HOW TO USE

      There is air control adjustment to be made this gun. This gun has been adjusted at the factory to produce the best possible atomization for all materials. If spray gun does not atomize paint satisfactorily the paint many require additional thinning or the air or paint passages may be clogged. The trigger adjustment is very critical. Open trigger only wide enough to produce the best possible atomization and spray pattern, then set the trigger adjustment screw in this position, the amount of trigger opening necessary will the viscosity and type of paint used opening trigger too wide will produce spray pattern and atomization. The spray gun is assembled at the factory with the lower end of the liquid tube facing forward the nozzle end of the gun. This position is most satisfactory for floors and vertical surfaces. For ceilings screw in tube one half turn so that lower end of liquid tube faces rear or handle end of gun.

SAFE WORKING AIR PRESSURE

      This spray gun is designed to operate most efficiently at air pressures between 20 and 45 PSI. In no case should more than 50 PSI pressure is used this gun before spraying. The quart cup should be screwed against the gasket tight enough to prevent excessive air leakage at this point a slight amount of air leakage at this point will prevent the gun from spraying properly. Care must be taken not on nick the top of the cup or to use defective gaskets which will permit air leakage, or the gun will not spray. If leakage of paint occurs through packing screw around the needle pin, tighten the packing screw just tight enough so that the needle will still move freely. An occasional drop of light machine oil on the packing will keep it soft and help prevent leakage.

SPRAYING PROCEDURE FOR LACQUER

      Greater care must be used when spraying lacquer than with older materials as lacquer dries very quickly and has a tendency to clog-up the gun. To pray lacquer successfully the operation should be continuous, that is the gun should not be set down for over a few minutes at a time.

IMMEDIATELY AFTER SPRAYING WITH LACQUERTHE GUN SHOULD BE THOROUGHLY WASHED OUTWITH LACQUER THINNER.

USING 2 1/2 GALLON PRESSURE PAINT TANK

Where large areas are to be sprayed, using this the quart cup can save much time. Liquid tube, cup cover and cup cover nut and attach paint hose at this point.

INTERNAL MIX NOZZLE

FAN NOZZLE

ROUND NOZZLE

ANGLE NOZZLE

Best for large flat surfaces such as walls, barns and garages, solid board fences, truck bodies industrial buildings. For irregularly shape pieces such as chair bicycle. Auto fender, toy, small furniture items and workshop projects. Projects a fan shape spray at an angle. May be adjusted on spray gun for spray ceiling or floors with gun help in up right position.

DIRECTIONS FOR SPRAYING

1.
Thoroughly mix the material adding thinners as indicated on label. Most materials in common use will spray readily. However, if material still appears too thick, add a litter more thinner, determining the amount by testing mixture in gun. Be sure the material you spraying is clean and free from lumps. Strain it through cheesecloth, regular paint strainer or a piece of common screw wire.

2.
Attach and hand tighten end of air hose to threaded fitting on the spray gun handle, retighten the hex hose fitting ? turn with wrench or pliers. Do not overtighten. Fill quart cup ? pull. Screw cup onto spray gun until tight.

3.
Set up several sheets of cardboard or newspaper against a wall to practice spraying on. Place the compressor 6 to 10 feet away from your work area and plug it in. be certain that spray on fumes can't reach any flame and there is plenty of ventilation.

4.
Begin spraying. Keep the gun at the right angles to your work by flexing your wrist at each of every stroke. Never allow a stiffly held wrist to "ARC" the stroke. This is a fault common to beginners. Arcing causes poor distribution of materials, too much at the center of reach stroke.

KEEP SPRAY GUN PARALLEL TO SURFACE, DON'T ARC

IF SPRAY GUN MOTION IS UNEVEN, PAINT FINISH WILL BE UNEVEN.

5.
Keep the distance between nozzle and work uniformly between 6 and 8 inches (15.2 and 20.3 cm.) Always keep gun in motion. If you hold it in one spot. Your material will "PILE UP" and an uneven coating will result.

6.
Learn to "TRIGGER" your gun to start and stop. The material properly. This means the gun must be moving at the beginning of the stroke before the trigger is pulled. Likewise the trigger must be released before the gun stops moving at the end of the stroke. The "FEATHERD" or blends each stroke with the next without showing unevenness or "LEAPS."

7.
Overleap your strokes on a flat surface just enough to secure an even coating. A few strokes on your practice sheets will quickly develop the needle skill.

8.
Use a "FRISKET" or cardboard shield to catch over-sprays at edges of work and to protect surfaces not to be painted. Where clean, separation on any job is required. As in 2-tone finishing masking tape should be used to cover areas not to be painted.

CLEANING INSTRUCTION *IMPORTANT*

       This spray gun must be thoroughly cleaned after using. As paint materials dry quickly in nozzle passages. To clean your spray gun, empty and wipe the cup. Pour a small amount of solvent or thinner in cup, screw on tight and hold trigger open until the thinner has been blown through the nozzle as in painting. The gun should be shaken while doing this to thoroughly was out the cup.
       Stopping and releasing the spray at the nozzle with the finger tip. Cause the thinner to surge violently and helps clean the material passages in the gun.
       Finish by wiping off the internal mix nozzle liquid nozzle and quart cup with cloth that has moistened with solvent. For a more through cleaning when paint and air passages are clogged with paint and gun not operating properly, disassemble gun and soak all metal parts in thinner or paint remove. After thinner or paint remove has softened paint in air and paint passages in gun handle. Take pipe cleaner and push this back and forth through all air and paint passages until they are opened and cleaned. Reassemble gun all parts have been wiped clean and place 2 or 3 drops of light machine oil on packing to keep it soft. If packing is dry and hard or worn, it should be replaced.

TROUBLE CHART

TROUBLE

CAUSE

1. If gun does not operate properly, check for. Air Leak.
Improperly prepared materials.
Improperly cleaned gun.

2. If material sags or runs: Material may be too thin.
Gun may be stroked too slowly.
Gun may be held too close to the work.
Trigger may be adjusted for too dense a spray

3. If material is hard to spray, check for: Air leaks.
Low voltage current.
Thick or unstrained material.

4. If spray pattern is distorted, look for:
Accumulation of material on end of liquid nozzle. Clogged internal mix nozzle.
Foreign matter in material.
Gun held at angle to surface.

5. If gun does not spray, look for: Loose air hose connections at gun or compressor.
Loose quart cup.
Clogged passages in liquid tube.
Loose damaged or clogged internal mix nozzle.

6. If spray pattern flutters, look for:
Loose quart cup or liquid tubes.
Dry or worn packing.
Loose packing.
Improperly strained or thinned material.
Gun tipped too far, allowing air to enter liquid tube along with paint.
