INTRODUCTION

HVLP stands for High Volume, Low Pressure. This is a type of spraying that allows you to spray 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. The HVLP Spray System is easy to use, safe and reduces the amount of paint used.

FIXING OF HOSE CLIP TO MAIN UNIT

2. Take L0505 (17) and place into left hand side of main unit as shown. Use the AC45 (19) screws supplied to fix the hose clips securely to the main unit.

IMPORTANT SELECTING PAINT

This is a highly versatile spray system 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 THE GUARANTEE. TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY SYSTEM 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 system. 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 system 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 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 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 grainy material, 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

This spray gun can be used with products having a viscosity ranging from 25 to 65 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. If the paint requires thinning, start with a 10% dilution of the paint. To do this, fill a 1litre container with the required paint. The viscosity cup supplied with the unit holds 1/10 of a litre, block the hole in the viscosity cup and fill up with the required thinner. Add the thinner to the paint and stir, measure the viscosity using the recommended viscosity chart above. If the paint requires further thinning, dilute the paint by another 5% (5% will be equal to half a viscosity cup) with the required thinner and measure the viscosity, if the paint is not at it's recommended viscosity, repeat the above step. Note: Some paints are outside the ranges listed above. Please contact our helpline for further information.

OPERATION

Fill the paint container with the material to be sprayed. DO NOT OVERFILL above MAX level indicator. Push the fluid tube firmly into the base of the spray gun body. Screw the container onto the gun body tightly. Place the motor unit onto a clean surface, free from any loose debris or liquids. Connect the hose to the back of the spray gun. Uncoil the mains cable 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 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.

z An airtight seal is essential for the correct operation of this gun. z Before operating the unit please ensure that the container is securely fixed to the gun body and the gland

nut (9) is not loose.

z Over time the gland seal (10) will wear and need adjusting. To check the gland nut is correctly fitted you

will need a small adjustable spanner. Pull the trigger back and gradually tighten the gland nut by turning it in a clockwise direction until the needle is not free to move when the trigger is released.

z To obtain the optimum setting gradually unscrew the nut by turning it in an anti-clockwise direction until

the needle moves forward into the fluid tip (4). To check your settings are correct spray a container of water. Re-adjust if necessary.

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 Horizontal is suitable for spraying up and down and the vertical is suitable for spraying from side to side, while 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 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.

PAINT VOLUME

The volume of paint sprayed is easily adjustable (Fig.4). Completely close the 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. Once the correct spray pattern is obtained you are able to commence spraying. The paint volume needs to be adjusted everytime you change the spray pattern especially when you use the round pattern, as this spray pattern can often contain too much paint.

Fig.4

SPRAYING TECHNIQUE

1. To obtain the best results always keep your spray gun level and at an equal distance from the object you are spraying, ideally 25-30cm (10”-12”) (side to side or up or down) from the surface (Fig.5a). Avoid spraying at an angle as this will lead to runs on the surface (Fig.5b).

2. Let your arm control the left to right movement rather than your wrist as this will help to give you an even paint distribution over the whole area.

3. Do not tip the spray gun to more than a 45

angle when the motor is switched OFF. You can tip the spray gun at more of an angle when spraying celings and decking etc, providing that the motor is switched ON. For spraying at angles, please change the direction of the Paint Feed tube (11) to the opposite angle that you are spraying, where there is more paint in the container.

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 thick 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.

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)

CLEANING INSTRUCTIONS

THE SPRAY GUN MUST BE THOROUGHLY CLEANED IMMEDIATELY AFTER USE. IF THE PAINT DRIES INSIDE THE GUN, CLEANING WILL BECOME MUCH MORE DIFFICULT AND MAY RENDER THE GUN INOPERABLE. THIS IS NOT COVERED BY GUARANTEE.

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.

SPRAY GUN

z Remove the gun container. z Pour any leftover paint into its container so that it can be used for the future. z Pour a quantity of the respective thinner into container, shake the spray gun lightly, reassemble the gun,

then spray this liquid through the gun. Repeat this until the thinner being sprayed is coming through with no traces of paint.

z Clean any traces of paint off the outside of the spray gun. z Clean the container Seal (12) inside the spray gun body.

FLUID TIP & NEEDLE

z Unscrew Air Cap Ring (1) z Remove the Air Cap (2) z Completely remove Fluid Adjusting Screw (8) z Remove the Spring (7) z Remove the Fluid Tip Needle (6) by gently pulling the trigger z Remove the Fluid Tip (4) z Remove Direction Plate noting the position of notches (3) z Remove Fluid Tip Seal (5) z Remove Paint Container Seal (12) z Place all of these items into a container and clean them using a brush and clean thinners z Clean the inside of the body of the gun z Thoroughly dry these parts before reassembling z Grease the Gland (10). (USE PETROLEUM JELLY. DO NOT USE SILICONE BASED GREASE.) z Reassemble parts in reverse order.

It is recommended fitting the Fluid Tip (4) prior to the needle.

NEVER DISPOSE OF PAINTS OR SOLVENTS INTO DRAINS. CONTACT YOUR LOCAL COUNCIL TO ARRANGE COLLECTION OR FOR DETAILS OF NEAREST REGISTERED DISPOSAL SITE.
