INTRODUCTION HVLP stands for High Volume, Low Pressure. This is a type of spraying that allows you to spray extremely accurately but 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. This gun is extremely easy to use, very safe and reduces the amount of paint used . PLEASE NOTE We have done all we can to ensure that used correctly and according to these instructions, this spray gun will give long and trouble free life. We accept no responsibility for damage caused by the use of incorrect or unsuitable substances, paints or fluids which have not been thinned correctly or are unsuitable for the surfaces to which they are applied, health hazards arising from lack of ventilation when working in confined spaces or failure of the equipment due to inadequate cleaning of the components after use. If in doubt, always test a small inconspicuous area first. Always read the paint manufacturer's instructions first. Neither our guarantee nor the above statement affects your statutory rights. 2 final.qxd 22/02/00 11:05 Page 3 PARTS LIST Key Discription No. 01. Hose Connector 02. Fluid Needle Assembly 03.

However some materials cannot be sprayed so please check the manufacturer's recommendation before buying the paint. If a material refers to brush application only then it cannot be sprayed. THIS CANNOT BE USED FOR TEXTURED EXTERIOR WALLPAINTS OR INTERIOR COATINGS. USE OF THESE MATERIALS WILL CAUSE PREMATURE WEAR, WHICH WILL VOID THE GUARANTEE. TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY GUN 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 gun. 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 gun is supplied with a viscosity cup. Viscosity is a technical term used to indicate if a product is very liquid or very thick. If liquid, the viscosity is said to be low, while if very thick the viscosity is said to be high. Viscosity is measured in seconds. In 4 order to spray some materials they need to be "thinned". 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 manufacturer's guide for thinning in conjunction with a spray gun. If in doubt please contact the manufacturer's of the paint. The viscosity cup supplied 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 provide you with trouble free spraying. Ensure that a face mask, gloves and goggles are worn at all times when spraying.

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. Combivac hose and the other end into the back of the Spray Gun. ALWAYS KEEP THE COMBIVAC UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO PREVENT PAINT CONTAMINATING THE MOTOR. MASK ANY AREA YOU DO NOT WISH TO BE SPRAYED Once you have set up ready to spray, switch on the Combivac. 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. Position the fluid tube in the paint container to provide the best angle to pick up all the paint in the container SPRAY PATTERNS Fig.3 Fig.1 OPERATION Fill the paint container with the material to be sprayed. DO NOT OVERFILL. Screw the container onto the body tightly. The spray gun is supplied with a hose. This is designed to fit into the hose supplied with the Combivac to give you sufficient length of hose to be able to spray most objects without limiting the spraying action. Vertical Jet Horizontal Jet Round Jet The gun has both adjustable volume control and 3 different spray patterns ­ Horizontal, Vertical and Round (Fig.3) 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. To adjust the spray pattern, loosen the adjustment ring (9), adjust the position of the nozzle (8) to obtain either a vertical, horizontal or round pattern then retighten the adjustment ring. 5 Fig.2 The Combivac hose needs to be fitted to the "Blower" outlet (Fig.2) ­ this is the outlet at the top of the machine. Connect the additional hose, supplied with the Spray Gun into the end of the final.qxd 22/02/00 11:05 Page 6 PAINT VOLUME The volume of paint sprayed is easily adjustable.(Fig.4) Fig.4 Completely close adjustment screw (4) 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 is too wide or contains too much paint turn the adjustment screw clockwise again. Once the correct spray pattern is obtained you are able to commence spraying. SPRAYING TECHNIQUE 1.To obtain the best results always keep your spray gun level and spray equally from side to side or up or down 25-30cm (10"-12") from the surface. Avoid spraying at an angle as this will lead to runs on the surface (fig.5). 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 sprayer to more than 45o angle. 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 output setting low as this will avoid excessive use of paints and will minimise overspray. 6 Fig.5 Fig.6 final.qxd 22/02/00 11:05 Page 7 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. 6). 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 sprayed 7. CLEAN SPRAYER AFTER EVERY USE (SEE CLEANING INSTRUCTIONS) NOZZLE AND NEEDLE ! Unscrew Adjustment Ring (9) ! Remove the Nozzle (8) ! Completely remove Adjustment Screw (4) ! Remove the Spring (3) !
