This type of spraying technology allows you to spray extremely accurately without all the overspray that occurs with the high pressure tank type equipment. In fact, in some parts of the world the high pressure systems are banned by law on environmental grounds and HVLP type systems are the only alternative for professional type spraying. The spray gun is extremely easy to use, very safe and reduces the amount of paint used. IMPORTANT SELECTING PAINT This is a highly versatile spray kit that can be used with several different spray mediums including varnishes, wood preservatives, enamels, oil and water based paints and cellulose. However some materials cannot be sprayed so please check the recommendation of the manufacturer before buying the paint. If a material refers to brush application only then it usually cannot be sprayed. THIS UNIT CANNOT BE USED FOR TEXTURED PAINTS. USE OF THESE MATERIALS WILL CAUSE PREMATURE WEAR, WHICH WILL VOID YOUR GUARANTEE. TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY KIT PLEASE READ THE INSTRUCTIONS CAREFULLY BEFORE USE. PREPARATION Preparation of the surface and thinning of the paint are the two most important areas to be concerned with to obtain the best results from your spray kit. Ensure all surfaces are free from dust, dirt, rust and grease. If necessary rub down with sandpaper, or similar. Masking of areas is important to ensure you do not spray those areas you wish to remain untouched. THINNING Your spray kit is supplied with a viscosity cup. Viscosity is a technical term used to indicate if a product is very thin or very thick. If thin, the viscosity is said to be low, while if very thick the viscosity is said to be high. Viscosity is measured in seconds. In order to spray some materials they need to be "thinned" (diluted). Thinning is very important when spraying. Most paints etc are supplied ready for brush application and may need to be thinned (diluted) for spraying purposes. Follow the manufacturers guide for thinning in conjunction with a spray gun. If in doubt please contact the manufacturers of the paint. The viscosity cup will help you determine the correct thickness of the paint. Paint is "thinned" by adding the substance which the paint is based upon. If a water based paint then water is added, if oil based then white spirit, if cellulose then a cellulose thinner is added. As some paints, wood preservatives and other sprayable materials contain particles that have differing qualities, please ensure that when filling the paint container of the spray gun, that the paint is filtered through either a funnel with a filter on it or through nylon tights or stockings. This will ensure that no large particles enter the paint container, so preventing blockages and providing you with trouble free spraying. Ensure that a face mask, gloves and goggles are worn at all times when spraying. IDEAL VISCOSITY Water based paints and emulsions Oil based paints Wood preservatives Primers 45 - 60 seconds 45 - 50 seconds No dilution 45 - 50 seconds Varnishes Aluminium paints Wood stains Cellulose No dilution No dilution No dilution Manufacturer's ratio This spray gun can be used with products having a viscosity ranging from 10 to a maximum of 60 seconds. Dip the viscosity cup into the material and fill up. Time how long it takes for the viscosity cup to empty (Fig 1). Using the above chart (or manufacturer's instructions) as a guide determine if the material requires further thinning, if so then thin accordingly. 4 Fig.1 L0199 09-04.qxd 14/2/05 10:13 am Page 5 Fill the paint container with the spray medium. Take care not to overfill. Take the spray gun unit and with the clamp lever (22) turned fully anti-clockwise, locate the spray gun unit into the paint container. Rotate the container until the 2 pins locate into the recesses in the yoke (23). Now turn the clamp lever clockwise to secure the container to the lid. Do not over tighten. Place the motor unit onto a clean floor space, free from any loose debris, liquids or dust sheets that could block the motor inlet. Unwind the hose from the main housing and connect to the back of the gun. Uncoil the mains cable from the base of the unit and plug in. ALWAYS KEEP THE MOTOR UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO PREVENT PAINT CONTAMINATING THE MOTOR. MASK ANY AREA YOU DO NOT WISH TO SPRAY. Once you have set up ready to spray, switch on the unit. No paint will be sprayed from the gun until the trigger on the spray gun is pulled. Before starting any work on spraying actual objects we suggest you spend a small amount of time practicing on cardboard or newspaper until you have got used to how the gun works. OPERATION SPRAY PATTERNS The gun has 3 different spray patterns ­ Horizontal, Vertical and Round (Fig.2). The horizontal and vertical are recommended for large surfaces. The round spray is used for small objects or for areas - such as corners ­ that are difficult to reach. Fig.2 To change the spray pattern simply rotate the Air Cap (2) until it clicks into the positions as shown in (Fig 2). The overall size of the selected spray pattern can be varied by turning the Air Cap Ring (1). When viewed from the front, rotate Horizontal Jet Round Jet it clockwise to increase the pattern size, or anti-clockwise to Vertical Jet reduce the pattern size. The volume of paint sprayed is easily adjustable (Fig.3). Completely close adjustment screw (12) by turning this clockwise as far as it will go. Whilst pulling the trigger, begin turning the adjustment screw anti-clockwise until the volume of paint you require is obtained. If the paint spray contains too much paint turn the adjustment screw clockwise to reduce it. Once you have set the spray pattern & the paint volume, you are ready to begin spraying. Fig.3 PAINT VOLUME 1. To obtain the best results always keep your spray gun level and spray equally from side to side or up or down from the surface. Avoid spraying at an angle as this will lead to runs on the surface (Fig.4). 2. Let your arm control the left to right movement rather than your wrist as this will aid even paint distribution over the whole area (Fig.5). 3. Do not tip the spray gun to more than 45°angle (Fig.6). SPRAYING TECHNIQUE Fig.4 Fig.5 Fig.6 NEEDLE & FLUID TIP SELECTION Paints, varnishes, wood treatments etc, are manufactured using a variety of materials & have widely different viscosities. You may find that the 2.0mm dia Fluid Tip & Needle supplied with this spray gun does not enable you to spray your particular choice of finish exactly as you would like. In such cases a change of Fluid Tip & Needle size will probably solve this problem. In general, thicker, more viscose materials are best sprayed through a larger Fluid Tip to give best coverage. Thinner, less viscose materials are best sprayed through a smaller Fluid Tip. To allow for these variations Fluid Tip & needle sets are available, as optional extras, in 1.0mm dia, 1.5mm dia & 2.5mm dia (See page 3). 5 L0199 09-04.qxd 14/2/05 10:13 am Page 6 HELPFUL HINTS 1. Evenly control the speed of movement of the spray gun. A fast speed will give a thin coat and a slow speed will give a heavy coat. 2. Only apply one coat at a time. If a further coat is required follow the paint manufacturer's instructions for drying times. 3. If spraying small areas or objects keep the adjusting screw setting low as this will avoid excessive use of paints and will minimise overspray. 4. When spraying large areas or objects, it is best to use a criss-cross pattern, either from left to right then up or down or vice-versa. This will ensure maximum coverage (Fig. 7). 5. Avoid stopping and starting when spraying as this can lead to too much or not enough material on a surface. 6. To ensure edges are covered, commence spraying just to the side of area being Fig.7 sprayed. 7. CLEAN SPRAY GUN AFTER EVERY USE (SEE CLEANING INSTRUCTIONS). CLEANING INSTRUCTIONS THE SPRAY GUN SHOULD BE THOROUGHLY CLEANED & THE GLAND WASHERS LUBRICATED, IMMEDIATELY AFTER EACH USE. IF THE PAINT DRIES INSIDE THE GUN CLEANING WILL BE MUCH MORE DIFFICULT & MAY RENDER THE GUN INOPERABLE. THIS IS NOT COVERED BY THE GUARANTEE. Flush out the residue paint from the spray gun, as follows: G Remove the paint container (17) from the spray gun. G Pour any residual paint into its original container for future use. G Use a cloth soaked in thinners to wipe out excess paint from the container, the underside of the lid (20) & the gasket (19). G Pour a small quantity of clean thinners into the container, re-fit the container to the spray gun and shake the gun lightly. G Now spray all of the thinners through the gun. G Repeat this, each time using clean thinners, until there is no trace of paint in the thinners being sprayed. To thoroughly clean the remainder of the spray gun, remove all working parts as per the exploded spare parts drawing on p.3 as follows. G Loosen and remove Air Cap Ring (1), Air Cap (2) and Air Distributor Plate & Spring (3). G Now unscrew the Adjusting Screw (12) and pull out the Needle (9) and Needle Spring (11). G Use the supplied spanner, to remove the Fluid Tip (4) and Fluid Tip Seal (5). All of the components above can be immersed in thinners and cleaned using the cleaning kit supplied with this product. After cleaning your spray gun and before fitting the needle, dip the tip into some vaseline which will lubricate the gland washers as the needle is inserted. The external surfaces of the spray gun can be wiped clean with a cloth soaked in thinners. NEVER DISPOSE OF PAINTS OR SOLVENT ...
