Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com SPECIFICATION AIR SUPPLY For best results, the air supply to the spray gun must be clean and dry, with no oil or water contamination. Follow the air compressor manufacturer’s guidelines on installation and operation to ensure that your air supply is as clean as possible. The compressed air supply line to the spray gun must be fitted with a filter capable of removing any oil or water together with a suitable pressure regulator. Higher pressure and contaminated air will shorten the spray gun life due to faster wear and could become a safety hazard. Water in the air line will also cause damage and may contaminate the paint being used. Therefore ensure the air supply is properly filtered. Line pressure, or supply hose inside diameter, should be increased to compensate for unusually long air hoses (over 10 m). Minimum hose diameter should be 6mm (¼”) ID, and fittings should have the same inside dimensions. The air inlet used for connecting air supply has a standard ¼” BSP thread.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com OPERATION The AP14GF spray gun is fed with paint by gravity from the paint container. The air-flow through the air cap draws paint into the nozzle assembly, where it is atomised and sprayed forward. The AP14GF spray gun is supplied with one nozzle size, (1.4 mm). Ensure your spray gun is matched to the capacity of your compressor. Connect the air supply hose to the air inlet, (using a suitable in-line connector if required). PREPARATION BEFORE PAINTING Mix the paint to the correct viscosity for spraying according to the manufacturer’s instructions and strain it into the paint container through a fine mesh filter. When mixing the paint, make sure that you have enough thinners left to clean the spray gun after use. Do not fill the paint container more than 3/4 full. Make sure that the threaded joint between the container and the gun are clean and before screwing the container on the gun. Always clean around the container sealing lip and keep the container vent clear. Remember that some modern paints require specialist respiratory protection...always consult the paint manufacturers instructions. Ensure that the area in which you will be spraying is clean and dust free. To obtain best results, it is vital that the surface to be sprayed is well prepared. It must be clean and dry, and free from dust, dirt oil or grease. Mask any area that is not to be sprayed and cover adjacent equipment to protect from overspray. Check the paint manufacturer’s instructions for any special surface preparation required. REMEMBER - TIME SPENT PREPARING SAVES TIME SPENT FINISHING. WARNING: NEVER ATTEMPT TO SPRAY UNLESS YOU ARE WEARING SUITABLE, APPROVED RESPIRATORY AND EYE PROTECTION.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com PAINT THINNING Paint thinning is particularly important when spraying. Many paints are supplied ready for brush application and need to be sufficiently diluted for spraying purposes. Always follow the paint manufacturers instructions. If in doubt, always consult the paint manufacturer. A Viscosity Cup (not supplied), will assist in determining the correct thickness of the paint. The ideal viscosity for most paints is as follows: 1. Dip the cup into the paint and fill to th e brim. Time how long it takes for the cup to empty. 2. Thin as required until times are achieved. 3. Alternatively if a viscosity cup is no t available, the following information can be used as a rough guide. Water based paints (emulsions) 10-20% water. Oil based paints (gloss ) up to 10% thinners. Cellulose paints up to 50% cellulose thinners. If in any doubt, contact the paint manufacturer. 4. Having mixed the paint thoroughly in a separate container, pour into the spray gun paint container through a fine filter. DO NOT OVERFILL PAINT CONTAINE R - never more than three quarters full. Water based paints 35-45 secs Oil based paints 15-25 secs Enamel paints 15-25 secs Primers 20-30 secs Varnishes 20-25 secs Aluminium paints 15-25 secs Wood preservatives Do not dilute Wood Stains Do not dilute Smooth masonry paint Dilute by 10-15%
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com ADJUSTMENTS OF THE SPRAY GUN ADJUSTING THE PAINT FLOW 1. Set the Paint Flow Adjustment knob (8) according to the paint in use and the spray pattern required. (anticlockwise to increase, clockwise to reduce flow). ADJUSTING THE SPRAY PATTERN 1. Turn the Pattern Adjustment knob (9 ) anticlockwise to give a fan shaped spray pattern, turning clockwise to give a circular spray pattern. 2. You can adjust the orientation of the fa n either vertically or horizontally to suit your requirements by turning the side wings (2) to the desired position. As the width of the spray is increase d, paint flow will also need to be increased. ADJUSTING THE AIR FLOW 1. To increase the air flow , turn the Airflow Adjustment knob anticlockwise to increase and clockwise to decrease the air pressure. The air flow needed will vary according to the paint in use, with thicker paints needing more air. SPRAYING TECHNIQUES Practice spraying on a piece of material with the same type of surface as the article you wish to spray, e.g. metal for a car body panel, wood for a piece of furniture etc. Always make adjustments to the spray pattern according to the conditions.You may need to increase the paint and air flow when using a wider fan setting. To reduce overspray, always use the lowest possible air pressure that produces an acceptable spray pattern. If the gun is too far from the surface or the paint is too thin, the paint will start to dry before hitting the surface, resulting in a rough, sandy finish. Allowing overspray to fall on a finished area will also result in a rough finish. Too much paint feed or holding the gun too close to the work will lead to runs and sagging. The paint should be agitated by gentle shaking at regular intervals during use to ensure consistency and avoid colour difference due to the paint settling in the container.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com To obtain the best results, keep your spray gun level and parallel to the surface at all times. Keep the nozzle 23 - 30 cm from the surface and spray evenly from side to side or up and down. Use your arm to control the spray gun, not your wrist. The gun should be perpendicular to the surface being covered and moved parallel with it. The stroke should be started before the trigger is pulled and likewise released before the stroke is ended. This gives accurate control of the gun and material. Do not spray at an angle as this will lead to paint runs on the surface. Always use smooth and even strokes. When spraying large areas, using a criss-cross pattern as shown. Never start or stop the spray gun while it is aimed at the surface to be sprayed. Evenly control the speed of movement of the spray gun. Moving quickly over the surface will give a thin coat and slow movement will give a heavy coat. Apply one coat at a time. If a further coat is required, make sure you observe the manufacturers drying time recommendations before applying a second coat. When spraying small areas, keep th e output control on a low setting as this will avoid using too much paint and prevent overspray. Where possible, avoid stopping and starting when spraying an object. This can lead to too much, or not enough paint being applied.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com The material deposited should al ways be even and wet. Lap each stroke over the preceding stroke to obtain a uniform finish. To ensure the edges are covered, start spraying just to the side of the area being sprayed and do not stop until the spray has gone past the opposite edge. Damage to the needle or nozzle, or any of the air ports, will result in a faulty spray pattern. Take care when cleaning or assembling these components. TROUBLESHOOTING Problem Cause Solution Atomisation is poor (paint comes out in blobs). Paint volume adjustment is incorrect (paint is too thick). Add thinners to paint and re-fill. Adjust air regulator to increase pressure. Over-painting. Spray gun not clean, resulting in needle valve sticking. Dismantle spray gun and clean with thinner. Too much paint. Adjust the volume regulator to reduce paint volume. Try spraying two thin coats of paint. Viscosity too low. Check the paint viscosity using a viscosity cup. Orange peel or fogging. Wrong thinner used. Use different thinner Spray gun held wrong distance from surface. Hold spray gun at different distance to the surface. Paint too thick. Thin the paint/test viscosity using a viscosity cup. Air pressure too high. Reduce air pressure. Rough texture as if paint is drying before hitting surface. Paint is too thin. Air pressure could be too high. Add more paint to container. Reduce air pressure.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com MAINTENANCE It is essential that the spray gun is kept clean. Dried paint in the nozzle assembly or airways will stop the gun from working. For the gun to perform at its best it must be thoroughly cleaned after every use. CLEANING PROCEDURE 1. After use, empty any remaining paint from the paint container, wipe the container clean with a dry, lint free rag, and fill with thinner. Spray the thinners through the spray gun until it is clean. 2. Residue from dirty solvent may clog th e narrow air passages in the gun. Use a cleaning brush and solvent to wash off accumulated paint. 3. Wipe down the outside of the gu n with a solvent dampened cloth. DO NOT poke any of the holes in the air cap or nozzle with metal instruments. These holes are precision drilled and can be damaged by probing with anything harder than a wooden toothpick. 4. Make sure that the air inlet vent to the paint container is kept clean. Blockages in this vent will prevent an even material flow through the gun. Component parts of spray guns are supplied in matched sets and should only be used together. Do not overtighten components, and be careful not to cross thread any parts on assembly. Never use silicon based lubricants as this may cause paint finish defects. 5. Check the air supply hose regularly for any signs of damage and replace it if necessary. Do not use damaged or leaking hoses. 6. Finally, empty the spray gun and dry all components thoroughly. Store in a clean, dry place. AIRLINE ACCESSORIES AND EQUIPMENT 1. An extensive range of airline equipment is available from your Clarke dealer including hoses, retractable hose reels, filter/regulators, in-line regulators, pressure gauges, spray gun cleaning kit, respiratory masks and safety goggles.
