2. Never direct a jet of compressed air at people or animals.
3. Always ensure that the equipment/tool being used as a safe working pressure exceeds the output pressure of the compressor that it is connected to.
4. Always ensure that the air supply is turned off at the tool outlet and vent all compressed air from the air hose and the equipment attached to it, before disconnecting air hoses or other equipment from your compressor.
5. Ensure all fixed air connections are properly sealed using Teflon tape or pipe sealant.
6. Never exceed the operating pressure as stated in the specification.
7. We strongly recommend that items contained in this kit be used in conjunction with appropriate eye and face-protecting goggles, glasses, or spray masks available from most DIY and hardware stores.

SPRAY GUN SPECIFIC WARNINGS

1. Never spray paint close to any source of heat or flame.

2. Always ensure the spraying area has adequate fresh air ventilation.

3. Always make sure there is adequate ventilation. Do not spray in confined or enclosed areas.

4. Always wear a suitable approved breathing mask when spraying, to protect against inhalation of paint spray or fumes. An air feed mask may be required when spraying toxic types of paint. If in doubt, check with the paint manufacturer.

5.  Always check the manufacturer’s data sheets on the paint products being sprayed for any particular hazards, and follow the manufacturer’s instructions. Take particular care if spraying isocyanate paints.

6. Always disconnect the spray gun from the air supply when it is not in use, and before any disassembly.

7. Always keep the spray nozzle in place when spraying.

SPRAY GUN OPERATION

CAUTION: THE ITEMS IN THIS KIT HAVE A LOWER WORKING PRESSURE THAN MANY COMPRESSORS WILL SUPPLY, THEREFORE, AN AIRLINE REGULATOR SHOULD BE INSTALLED. SEE PAGE 2 FOR WORKING PRESSURES.
CAUTION: AIRLINE LUBRICATORS SHOULD NOT BE USED WITH THESE ITEMS

This professional type gravity-fed spray gun is suitable for use with most conventional paints. The spray gun is fed with paint from the paint container. The airflow through the air cap draws paint into the nozzle assembly, where it is atomized and sprayed forward.

1. Your air compressor must be capable of supplying air at 8 CFM for the satisfactory performance of the spray gun.
2. Follow all safety precautions when attaching the spray gun to the air hose.

PREPARATION BEFORE PAINTING

1. Mix the paint to the correct viscosity for spraying according to the paint manufacturer’s instructions and strain it into the paint container through a fine mesh filter. When mixing the paint, make sure that you have enough thinners left to clean the spray gun after use.
2. Do not fill the paint container to more than 3/4 full. Make sure that the top edge of the container and lid are clean and free from damage before mounting the gun on the container. It is also very important to keep the container vent clear.
3. Remember that some modern paints require specialist respiratory protection. Always consult the paint manufacturer’s instructions. WARNING: NEVER ATTEMPT TO SPRAY UNLESS YOU ARE WEARING SUITABLE, APPROVED RESPIRATORY AND EYE PROTECTION.
4. Ensure that the area in which you will be spraying is clean and dust-free. To obtain the 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 and cover adjacent equipment to protect from overspray.
5. Check the paint manufacturer’s instructions for any special surface preparation required.
   • REMEMBER – TIME SPENT PREPARING SAVES TIME SPENT FINISHING.

PAINT THINNING

Paint thinning is particularly important when spraying. Many paints are supplied ready for brush application and need to be sufficiently diluted for spraying purposes. Always follow the paint manufacturer’s instructions. If in doubt, always consult the paint manufacturer.
A Viscosity Cup (not supplied), will assist in determining the correct thickness of the paint.
The ideal viscosity for most paints is as follows:

1. Dip the cup into the paint and fill to the brim. Time is how long it takes for the cup to empty.

2. Thin as required until times are achieved.

3. Alternatively, if a viscosity cup is not available, the following information can be used as a rough guide.
   • Water-based paints (emulsions) 10-20% water.
   • Oil-based paints (gloss) up to 10% thinners.
   • Cellulose paints up to 50% cellulose thinners.

4. If in any doubt, contact the paint manufacturer.

5. Having mixed the paint thoroughly in a separate container, pour it into the spray gun paint container through a fine filter.
   • DO NOT OVERFILL PAINT CONTAINER – never more than 3/4 full.

ADJUSTMENT OF THE SPRAY GUN

ADJUSTING THE PAINT SPRAY PATTERN

1. Set the Spray Adjustment regulator according to the paint in use and the spray pattern required to give either a wide, fan-shaped spray pattern or a narrow spray pattern.
   • As the width of the spray is increased, paint flow will also need to be increased.

2. You can adjust the orientation of the fan pattern either vertically or horizontally to suit your requirements by turning the nozzle side wings to the desired position.

ADJUSTING THE AIRFLOW

1. To adjust the airflow, turn the airflow Regulator to regulate its supply.
   • The airflow needed will vary according to the paint in use, with thicker paints requiring more air.

SPRAYING TECHNIQUES

1. To avoid creating a vacuum, remove the vent cap from the top of the paint container before spraying. Replace the cap to avoid spillage when you stop.

2. Practice spraying on a piece of material with the same type of surface as the item you wish to spray, e.g. metal for a car body panel, wood for a piece of furniture, etc.

3. Always make adjustments to the spray pattern according to the conditions. You may need to increase the paint and airflow when using a wider fan setting.

4. To reduce overspray, always use the lowest possible air pressure that produces an acceptable spray pattern.
   • If the gun is too far from the surface or the paint is too thin, the paint will start to dry before hitting the surface, 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.
   • The paint should be agitated by gentle shaking at regular intervals during use to ensure consistency and avoid color differences due to the paint settling in the container.

5. To obtain the best results, keep your spray gun level parallel to the surface at all times. Keep the nozzle 23 – 30 cm from the surface and spray evenly from side to side or up and down. Use your arm to control the spray gun, not your wrist.

6. 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.

7. Do not spray at an angle as this will lead to paint runs on the surface. Always use a smooth and even stroke.

8. When spraying large areas, use a criss-cross pattern as shown.

9. Never start or stop the spray gun while it is aimed at the surface to be sprayed. Evenly control the speed of movement of the spray gun.
   • Moving quickly over the surface will give a thin coat and slow movement will give a heavy coat.• Apply one coat at a time. If a further coat is required, make sure you observe the manufacturer’s drying time recommendations before applying a second coat.
   • When spraying small areas, keep the output control on a low setting as this will avoid using too much paint and prevent overspray.

10. Where possible, avoid stopping and starting when spraying. This can lead to too much, or not enough paint being applied.
    • The material deposited should always be even and wet. Lap each stroke over the preceding stroke to obtain a uniform finish.
    • To ensure the edges are covered, start spraying just to the side of the area being sprayed, and do not stop until the spray has gone past the opposite edge.
    • Damage to the needle or nozzle, or any of the airports, will result in a faulty spray pattern. Take care when cleaning or assembling these components.

COMMON PAINT SPRAYING PROBLEMS

is incorrect for the air
volume (paint is too thick).| Add thinners to paint and re-fill. Adjust air regulator to increase pressure.
Over-painting.| Spray gun not clean, resulting in needle valve
sticking.| Dismantle spray gun and clean with thinner.
Too much paint.| Adjust the volume regulator to reduce paint
volume. Try spraying two thin coats of paint.
Viscosity too low.| Check the paint viscosity using a viscosity
cup.
Orange peel or fogging.| The wrong solvent was used.| Use different solvents.
The spray gun held the wrong distance from the surface.| Hold spray gun at different distances to the
target.
Paint too thick.| Thin the paint/test viscosity using a viscosity
cup.
The Air pressure is too high.| Reduce air pressure.
Rough texture as if the paint is drying before hitting
surface.| The paint is too thin.

Air pressure could be too
high.

| Add more paint to the container.
Reduce air pressure.

MAINTENANCE

SPRAY GUN MAINTENANCE

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 thoroughly cleaned after every use.

CLEANING PROCEDURE

1. After use, empty any remaining paint from the paint container, wipe the container clean with a dry, lint-free rag, and fill with thinner. Spray the thinners through the spray gun until it is clean.

2. Residue from dirty solvents may clog the narrow air passages in the gun. Use a small cleaning brush and solvent to wash off accumulated paint.

3. Wipe down the outside of the gun with a solvent dampened cloth
   • DO NOT poke any of the holes in the nozzle with metal instruments. These holes are precision drilled and can be damaged by probing with anything harder than a wooden toothpick.

4. Make sure that the air inlet vent to the paint container is kept clean. Blockages in this vent will prevent an even material flow through the gun.
   • Component parts of spray guns are supplied in matched sets and should only be used together.
   • Do not overtighten components, and be careful not to cross-thread any parts on assembly.
   • Never use silicone-based lubricants which may cause paint finish defects.

5.  Check the air supply hose regularly for any signs of damage and replace it if necessary. Do not use damaged or leaking hoses.

6. Finally, empty the spray gun and dry all components thoroughly. Store in a clean, dry place.
