Pro-Gun spray guns are available with two nozzle sizes, 1.4mm, and 1.8mm. The larger the nozzle, the more compressed air is needed. Make sure your spray gun is matched to the capacity of your compressor. Model Nozzle size Compressor required PGF-14 1.4 mm 2 hp and above PGF-18 1.8 mm 3 hp and above 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 an oil and water extractor and a suitable pressure regulator. Connect the air supply to the spray gun using a suitable 1/4” BSP fitting. AIR SUPPLY - 5 - - 10 - Trigger PAINT SPRAYING HINTS Cont To obtain best results, it is vital that the surface to be sprayed is well prepared. It must be clean, free from dust, dirt and grease. Mask any area that is not to be sprayed. Paint Thinning Thinning is particularly important when paint spraying. Most 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 Viscous Cup (not supplied), will assist in determining the correct thickness of the paint. Wood preservatives .... Do Not Dilute Smooth Masonry paint....dilute by 5 - 10% Ensure the paint is free from lumps or other matter, if necessary strain it through a coarse filter. The ideal viscosity for most paints is given in the chart opposite. Dip the cup into the paint and fill to the brim. Time how long it takes for the cup to empty. Thin as required until times are achieved 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 Alternatively if a viscous cup is not available, the following information can be used as a rough guide.

• 6 -- 9 - PGF spray guns are gravity fed with paint from the paint cup. The air flow through the air cap draws paint into the nozzle assembly, where it is atomised and sprayed forward. Attach the paint cup to the gun, ensure any seals etc are sound first, mix the paint to the correct viscosity for spraying according to the manufacturers instructions, and strain it into the paint cup 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 cup to more than 3/4 full. Make sure that the top edge of the cup and the cup sealing gasket are clean and free from damage before screwing the cap on, it is also very important to keep the cup vent clear. Set the spray pattern and fluid flow using the adjustment screws on the spray gun. The spray pattern is variable between round and fan by adjusting the air flow through the air cap. Turn the fan control anticlockwise to increase flow and give a fan shaped spray pattern, turning clockwise to close off the air flow will give a circular pattern. The fan can be adjusted vertically or horizontally to suit your requirements by loosening the knurled locking ring and turning the wings to the desired position. Set the fluid flow according to the paint in use and the spray pattern by using the fluid control screw; anticlockwise to increase, and clockwise to reduce flow. As the width of the spray is increased, fluid flow will also need to be increased. The air pressure needed will vary according to the paint in use, with thicker paints needing greater pressure. For most paints, a pressure of between 22 psi and 43 psi is adequate, to increase the air pressure, turn the air control anticlockwise to increase, and clockwise to decrease the air pressure. NOTE: To reduce overspray and obtain maximum transfer efficiency, always use the lowest possible air inlet atomising pressure that produces an acceptable spray pattern. The first requirement for a good resultant finish is the proper handling of the gun. 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. The distance between the gun and the surface to be covered should be 6 to 12 inches depending on the material and atomising pressure. The material deposited should always be even and wet. Lap each stroke over the preceding stroke to obtain a uniform finish. Damage to the fluid needle or nozzle, or any of the air ports, will result in a faulty spray pattern. Take care when cleaning or assembling these components. When spraying, the gun should be held square to the surface being painted, at a distance of 6 to 12 inches depending on the paint and atomising pressure. Keep the gun parallel to the surface being sprayed, starting the stroke before pulling the trigger, and releasing the trigger before ending the stroke. Overlap each stroke over the preceding stroke to obtain an even finish. The paint cover should be even and wet when spraying. If the gun is too far from the surface, or the paint is too thin, the paint will dry before hitting the work, 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. PAINT SPRA YING HINTS WARNING NEVER attempt to spray unless you are wearing suitable, approved respiratory and eye protection. REMEMBER that some modern paints require specialist respiratory protection...always consult the paint manufacturers instructions. 1. General Preparation a. Ensure that the area in which you will be spraying is clean and dust free. b. Connect spray gun to compressor via suitable flexible hose. c. With no paint in spray gun, test system for air leaks. d. Cover adjacent pieces of equipment to protect from overspray. Mask areas of the article not to be sprayed. e. Ensure surface to be painted is clean, dry and free from oil and dust. Check paint manufacturer’s instructions for any special surface preparation required. REMEMBER - TIME SPENT PREPARING SAVES TIME SPENT FINISHING 2. Paint Preparation a. Achieve the correct paint viscosity. This should be done according to paint manufacturer’s instructions, and will vary according to type of paint, (see paint thinning on page 9). b. Having mixed the paint thoroughly in a separate container, pour into the spray gun paint container through a fine filter. DO NOT OVERFILL SPRAY GUN PAINT CONTAINER - three quarters full is maximum c. It is usually best to experiment with a couple of practice spray coats on a piece of material with the same type of surface as the article you wish to spray, eg. metal for a car body panel, wood for a piece of furniture etc. d. Some common problems: PROBLEM CAUSE CORREC TION Paint does not atomise. Paint is too thick. Add thinners. (comes out in blobs). Air pressure is too low. Increase air pressure.

• 7 - - 8 - WARNING Relieve any pressure in the gun and hose, and disconnect the spray gun from the air supply, before any disassembly. 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 cleaned and lubricated after every use. After use, empty any remaining paint from the paint cup, wipe the cup clean with a dry, lint free rag, and fill with thinners. Spray the thinners through the spray gun until it is clean. 1. Immerse only the front end of the gun until solvent just covers the fluid connection. NOTE : do not submerge the entire spray gun in solvent because : a, the lubricant in the seals/packings will dissolve and the packings will dry out. b, the lubricant at wear surfaces will dissolve resulting in harder operation and premature wear. c, residue from dirty solvent may clog the narrow air passages in the gun. 2. Use a small bristle brush and solvent to wash off accumulated paint. 3. Wipe down the outside of the gun with solvent dampened cloth. 4. Lubricate the gun daily, using a light machine oil on : a, fluid needle packing b, air valve packing c, spray width adjuster d, trigger pivot point Coat the fluid control spring with grease. CAUTION : never use silicon based lubricants as this may cause paint finish defects. 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. Make sure that the air inlet vent to the paint cup is kept clean. Blockages in this vent will prevent an even material flow to the gun. Occasionally it may be necessary to strip the gun down for more in depth cleaning and or replacement of parts etc, to do this proceed as follows. NOTE: Ensure all parts are carefully laid out in the order that they are removed. 1. Remove the air cap set ( item 01) by unscrewing the knurled locking ring in an anticlockwise direction. 2. Unscrew and remove the fluid control knob ( item 12) along with the knurled locknut (item 11), hold the gun with the nozzle facing downwards to ensure the spring doesn’t fall out. 3. Tip gun upwards to remove the spring ( item 10). 4. Carefully withdraw the fluid needle ( item 09), it may help to squeeze the trigger ( item 37) whilst pulling the needle, DO NOT use pliers etc, as this may damage the needle. 5. Remove the fluid nozzle assy ( items 02, 03 & 04). Locate the wrench (item 35) supplied, on the fluid nozzle ( item 02) and turn clockwise (left handed thread). 6. Separate the fluid nozzle and air diversion ring, secure the socket spanner supplied MAINTENANCE Item Nos in brackets refer to parts list on page 12. (34) in a vice with the hexagonal section facing upwards, NOTE: grip the spanner across flats not on the round section , place the nozzle assy onto the spanner, using the wrench, loosen and unscrew the nozzle, anticlockwise. When reassembling, ensure the nozzle is locked firmly onto the air diversion ring. 7. Locate the socket spanner on to the Compression screw ( 05) and unscrew by turning anticlockwise with the handle end of the wrench on the hexagonal section of the spanner. Remove parts, compression screw (05), valve (05a), compression spring (06) and seal ( 07), it may be necessary to push the seal out using the fluid needle. No further disassembly should be necessary for normal maintenance activities, Reassemble in gun in reverse order, to fit parts 05, 05a, 06 and 07, this must be carried out as follows.
• Fully Insert the fluid needle ensuring it passes through the hole in the fluid needle pin (item 25), hold in position by placing index finger on blunt end of the needle. With the needle facing upwards, fit the parts in the order listed above, ensuring the correct orientation as removed, if necessary refer to the parts diagram.
• Locate the box spanner over the needle pin and push down until the spanner engages fully on the compression screw, carefully tighten by hand at this stage only. It should now be possible to move the fluid needle in and out by hand without using excessive force, if needle moves smoothly, remove it completely and tighten the compression screw with box spanner. Refit the needle and again ensure it moves smoothly without forcing. Push the fluid needle fully home, fit spring followed by the fluid control knob and locknut.
• Place the piston pad ( 04) onto the gun body ensuring the locator is in the top hole of the body.
• Screw the nozzle assy, anticlockwise into the gun body and tighten securely using the wrench, DO NOT overtighten. Re-fit the air cap set with the wings horizontal, tighten the knurled locking ring, hand tight only. never mix components from spray guns, even those of the same type. Do not overtighten components, and be careful not to cross thread any parts on assembly. Air Piston Assembly If it is found necessary to remove items 13,14,15,16,17 & 18, proceed as follows:
• Using two flat bladed screwdrivers, loosen and remove the trigger bolt (items 22 &24).
• loosen the air piston using a 13mm ring spanner preferably. The complete assy can now be removed. Fluid Control
• To remove the control valve, unscrew and remove the countersunk screw ( 21).
• Using a 14mm ring spanner, loosen and remove the valve assembly. Air Adjustment V alve
• Using a 12mm ring spanner, unscrew and remove valve assembly ( 31). Reassemble all removed parts in reverse order. Check the air supply hose regularly for any signs of damage, and replace it if necessary. Do not use damaged or leaking hoses.
