General Information

Please make sure that you read these instructions carefully to avoid injury when using the

HVLP spray gun. Follow all health and safety rules and regulations. If in doubt and available

please contact a more knowledgeable source.

DO NOT use if damaged.

• If the spray gun is damaged do not use as this may cause damage to property or injury.

• Maintain the spray gun in good and clean condition for best and safest performance.

• Keep the work area clean and uncluttered and ensure that there is adequate lighting.

• Maintain correct balance and footing. Ensure the ﬂoor is not slippery and wear

non-slip shoes.

• Keep children and unauthorised persons away from the work area.

• When the spray gun is not in use always ensure the air supply is turned off.

• ALWAYS make sure the spray gun is disconnected from the air supply before changing

accessories, servicing or performing any maintenance.

• BE AWARE the paint cup remains pressurised after the gun has been disconnected

from the airline. Depressurise the paint cup by gently opening, do not pull the trigger.

• BE AWARE paints and solvents may be harmful or fatal if swallowed or inhaled. Avoid

prolonged contact with solvents or paint on the skin as it will cause irritation. After any

contact, immediately wash the exposed area with hot, soapy water.

• BE AWARE that air hose ﬁttings may get hot during use. Allow all the ﬁttings to cool

down before you disconnect.

• ALWAYS dress appropriately – protective overalls, paint spraying gloves and boots are

recommended.

• ALWAYS wear the correct eye or face protection when operating the spray gun.

• ALWAYS wear approved respiratory protection.

• NEVER point the spray gun at yourself, at other persons or animals.

• DO NOT carry the spray gun by the air hose.

Safe use

• DO NOT operate the spray gun while tired or under the inﬂuence of alcohol, drugs or

medication.

• DO NOT allow untrained persons to operate the spray gun.

• DO NOT exceed the maximum air pressure.

• DO NOT get the spray gun wet or use in damp or wet locations or areas where there is

condensation.

• DO NOT spray near open ﬂames, pilot lights, stoves, heaters, the air compressor or

another heat source. Most solvents and coatings are highly ﬂammable, in particular

when sprayed. Keep a distance of at least 25 feet from the air compressor. If you can,

locate the air compressor in a separate room.

• NEVER use the spray gun to spray hazardous materials. This may result in serious

injury or death. Do not spray pesticide, acid, corrosive material, fertilizer or toxic

chemicals.

Before using the spray gun check for damage. If the spray gun is damaged do not use as this will

affect the performance and could cause damage to property or injury. Check for the following –

• Loose screws

• Misalignment or binding of moving parts

• A clogged nozzle or ﬂuid tip

• Damaged air supply hose

• Cracked or broken parts

• Check the cleanliness of the spray gun

• Anything else that could affect safe operation

Air Supply Connection / Adjustment

1. Before connecting the spray gun to the air supply always ensure that the spray gun air

valve is in the ‘off’ position.

2. You will require an air pressure of 50 PSI.

ALWAYS ensure when using the spray gun that the air supply is clean and does not exceed

50PSI. Using unclean air and air pressure that is too high will result in the product life being

shortened for the spray gun due to excessive wear. This may result in the spray gun becoming

dangerous and causing damage to property and/or injury.

Work Area Set Up

1. Keep the work area clean and uncluttered and ensure that there is adequate lighting.

2. Ensure there are no children or pets within the work area that could cause distraction

or injury.

3. Make sure the air hose route can reach the work area without creating a tripping

hazard. Ensure the air hose is long enough to allow free movement whilst working.

4. Before you begin spraying, mask nearby objects that are not being sprayed.

Fan Direction

To change the direction of the fan from horizontal to vertical, loosen the retaining ring (2)

and turn the air nozzle 90°.

NOTE - Test the consistency by spraying onto a piece of scrap material.

As the width of spray is increased more material must pass through the spray gun to obtain

the same coverage on the increased area.

1. Thread the cup to the top of the spray gun and tighten until the cup is securely in place.

2. Follow the paint manufacturer’s directions for prepping the paint and mix thoroughly.

3. Unscrew the lid on the cup. Fill the cup with the paint ¾ full. Secure the lid back onto

the cup and tighten.

4. Start the air compressor and set the regulator to the needed pressure. NEVER exceed

the maximum air pressure.

5. Use the adjustment valve (6) to adjust the pressure according to the paint

concentration.

6. Use the adjustment knob (4) to adjust the atomization length.

7. Use the adjustment screw (5) for adjusting the amount of paint liquid.

8. Turn the air nozzle (1) to achieve either a horizontal or vertical fan spray.

9. Lock the nozzle in place with the retaining ring (2).

Spray Gun Set Up

ﬁg.1

Spraying Technique

1. Hold the spray gun perpendicular to the surface being sprayed and move it parallel to it.

2. Use two hands, one to steady the cup and the other to operate the spray gun.

3. Aim the nozzle at the piece of material that you would like to spray.

DO NOT stop when spraying. If you need to stop for more than 5 minutes, turn off the air

supply, disconnect the cup from the spray gun, and thoroughly rinse the cup and spray gun

with clean water.

4. Pull the trigger slowly and move the spray gun parallel to the workpiece you are

spraying. Keep a distance between the spray gun and the material to about 6” to 9”,

depending on the ﬂow adjustment and the paint (refer to ﬁgure 1).

5. To avoid paint building up in the spray gun, start the stroke before squeezing the trigger.

6. To obtain a uniformed ﬁnish each stroke must overlap the preceding stroke.

7. When you have ﬁnished, release the trigger before ﬁnishing the stroke.

DO NOT stop moving the spray gun while spraying.

ALWAYS allow are hose ﬁttings to cool down completely before dismantling the spray gun.

8. Release the trigger, disconnect from the air supply, and safely discharge any residual air

pressure.

9. Clean the spray gun immediately after every use, in between coats and when it is not

being used for 5 minutes or longer.

Cleaning

ALWAYS make sure that the spray gun is cleaned immediately after every use. Delayed or

inadequate cleaning of the spray gun will cause blockages and affect the performance of the

product in the future.

ALWAYS disconnect the spray gun from the air supply before attempting to clean or

perform maintenance.

ALWAYS follow the paint manufacture’s recommendations for cleaning, solvent and

disposal.

Cleaning the spray gun cup

1. Make sure any solvent used is recommended by the paint manufacturer.

2. Remove the cup, as well as any tubes.

3. Scrape the paint out of the cup carefully. Dispose of this excess paint properly.

4. Clean the cup with the solvent.

5. Allow to dry.

Cleaning the spray gun

1. Immerse the front end of the spray gun only in solvent.The solvent should just cover the

ﬂuid connection. DO NOT immerse the entire spray gun in solvent. This can cause the

lubricants on the rubber seals to dissolve. The dirty solvent may also clog narrow

passages in the spray gun.

2. To wash off any paint that has accumulated on the spray gun use a bristle brush and

solvent.

3. Flush the spray gun through with clean thinners.

4. With a dampened solvent rag wipe the outside of the spray gun.

5. Allow to dry.

Air nozzle, ﬂuid nozzle and needle assembly

1. To clean the nozzles soak them in solvent to dissolve any dried material then blow them

clean with air. Carefully handle all nozzles and do not make any alterations to the gun.

2. If you need to probe the holes in the nozzles, do not use metal instruments. Always

ensure you use a tool that is softer than brass.

3. Adjust the ﬂuid needle valve so that when the gun is triggered airﬂow occurs before ﬂuid

ﬂow.

1. Always take care when re-assembling the spray gun. Avoid cross-threading by screwing

the parts hand tight. If a part cannot easily be turned by hand, check that you have the

correct part, or unscrew, realign and try again. DO NOT use excessive force when

re-assembling.

2. With a light machine oil, lubricate the spray gun daily.

3. If you change the nozzle size, ensure the complete nozzle set is exchanged. Before

putting the paint needle in, insert the paint nozzle.
