User manual EARLEX SPRAY SYSTEM HV 1900

[. . . ] G Always read the paint manufacturer's thinning instructions before using. G Always disconnect unit from mains supply when refilling the paint container. G After every use ensure that you clean your spray gun thoroughly and grease the gland packing. WARNING: The substances used with this spray gun (paint, thinners etc) may contain hazardous, harmful, explosive or corrosive materials. [. . . ] 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. In order to spray some materials they need to be "thinned" (diluted). Most paints 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. 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 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 Manufacturers ratio This spray gun can be used with products having a viscosity ranging from 10 to a maximum of 60 seconds. 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 OPERATION Fill the paint container with the material to be sprayed. Place the motor unit onto a clean surface, free from any loose debris or liquids. ALWAYS KEEP THE MOTOR UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO PREVENT PAINT CONTAMINATING THE MOTOR. No paint will be sprayed until the trigger on the spray gun is gently pulled. Before starting any work on spraying actual objects we suggest you spend some time practicing on cardboard or newspaper until you have got used to how the spray gun works. SPRAY PATTERNS The spray gun has 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. Fig. 3 To adjust the spray pattern, loosen the Air Cap Ring (1), adjust the position of the Air Cap (2) to obtain either a vertical, horizontal or round pattern then re-tighten the aircap ring. Vertical Jet Horizontal Jet Round Jet PAINT VOLUME The volume of paint sprayed is easily adjustable. (Fig. 4) Completely close Fluid Adjusting Screw (8) 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 Fluid Adjusting Screw clockwise again. [. . . ] The spray gun is the same as a paintbrush, if it is not cleaned it will go hard and can become useless. You must therefore clean this out after use. G G G G G SPRAY GUN Remove the gun container. Pour any leftover paint into its container so that it can be used for the future. Pour a quantity of the respective thinner into container, shake the spray gun lightly, reassemble the gun, then spray this liquid through the gun. [. . . ]
