Follow the manufacturer’s directions. Most paints will spray easily if they are thinned properly. 2. Thin the paint according to manufacturer’s directions and mix thoroughly. 3. Carefully strain the paint through a paint strainer or a piece of cheesecloth. 4. Fill the Cup to 3/4 full. Close Cup. 5. Start the air compressor and set the regulator to needed pressure. Do not exceed maximum air pressure. 6. Test the consistency by spraying on a piece of scrap material. If it still appears too thick, add a very small amount of thinner (not included)and mix thoroughly. Use the proper thinner for the type of paint. Thin CAUTIOUSLY. Proceed slowly, adding minimal amounts at a time. DO NOT exceed the manufacturer’s thinning recommendations. Fan Direction 7. Figure D: Fan DirectionHorizontal FanVertical FanNozzleLock RingTo change the direction of the fan from horizontal to vertical, loosen the Lock Ring and turn the Nozzle 90°. 8. After the adjustment, tighten the Lock Ring by hand. Pattern Adjustment WARNING! Do not exceed the Maximum Air Pressure shown on the Specification chart. 9. Adjust the air supply pressure during operation with the Trigger fully depressed and the Air Knob fully open. If reducing air pressure for specific areas, use the Air Knob. 10. Use the Pattern Knob to adjust the spray pattern. Turn Pattern Knob counterclockwise (all the way open) to flatten the spray pattern. Turn it clockwise for a round spray pattern - see Figure E: Pattern Adjustment. Figure E: Pattern AdjustmentFlat/ OpenRound/ Closed Fluid Adjustment 11. Turn the Fluid Knob clockwise until it is fully closed. 12. After setting up a piece of scrap material, squeeze the Trigger in short bursts while turning the Fluid Knob counterclockwise to set the amount of fluid - see Figure F: Fluid Adjustment. Too Fine(Decrease air flow) Too Coarse (Increase air flow) CorrectFigure F: Fluid Adjustment If spray is too fine: Reduce the air pressure or allow more paint to come out by opening the Fluid Knob. If spray is too thick (globs of paint): Close the Fluid Knob slowly, checking the pattern after each adjustment. Note: Change nozzle and needle size according to the thickness and type of paint being used. Generally, larger diameter nozzles are more suitable for thicker paints. Spraying Technique IMPORTANT: Proper spraying technique is ESSENTIAL to achieve good results. 1. First, prepare the Spray Gun according to the instructions under Spray Gun Setup Adjustment on page 11. 2. Keep the Spray Gun upright and at a right angle to the workpiece - See Figure G and Figure H. Figure G: Spray Gun Angle - top view Incorrect Gun AngleDo not pivot your wrist or wave the gun like a fan towards the wall. Move your arm, not just your wrist. Point gun directly towards the surface and maintain an even, steady distance and speed. Correct Gun Angle Figure H: Spray Gun Angle - side viewCorrect Gun AngleIncorrect Gun Angle 3. Using two hands, one to steady the Cup and the other to operate the Spray Gun, aim Nozzle at the workpiece. CAUTION: DO NOT STOP WHEN SPRAYING. Spraying materials will start to set and dry as soon as they come in contact with the air. They will cause a permanent clog if not cleared immediately. If discontinuing spraying for more than half an hour, turn off the air supply, disconnect Cup from Gun Body and thoroughly rinse Cup and Gun Body with fresh, clean water. 4. Pull Trigger slowly and move Spray Gun in parallel strokes to the workpiece. Keep the distance from the workpiece at about 6. to 9., depending on the flow adjustment and the paint. 5. To avoid paint build up, start moving the Spray Gun before squeezing the Trigger. When finished with the stroke, release the Trigger while still moving the Spray Gun - see Figure I. Doing this will produce a smoother finish. Do not stop moving the Spray Gun while spraying. If the Spray Gun stops even briefly while spraying the paint will build up and run down the workpiece. Figure I: Paint Stroke Triggering - top viewEndStrokeBegin StrokeRelease TriggerSqueezeTrigger Note: The stroke speed, the Fluid Knob adjustment, and the distance from the workpiece, will determine how much paint is being applied. Apply two thin coats rather than one thick coat. CAUTION! Air hose fittings may get hot. Allow fittings to cool before disconnecting, or wear gloves to prevent burns. 6. To prevent accidents, release trigger, detach air supply, safely discharge any residual air pressure, and again release trigger after use. 7. Clean Spray Gun thoroughly immediately after EVERY use, according to instructions on the following pages. Safety Setup Operation Maintenance User.Maintenance Instructions Procedures not specifically explained in this manual must be performed only by a qualified technician. TO PREVENT SERIOUS INJURY: Detach the air supply and safely discharge any residual air pressure in the tool before performing any inspection, maintenance, or cleaning procedures.
