1. Always make sure the spray gun air valve is in the ‘off’ position before connecting to the
air supply.
2. You will require air pressure of 43 PSI.
ALWAYS ensure when using the spray gun that the air supply is clean and does not exceed
43PSI. 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 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 paint adjustment knob to adjust the amount of paint flow.
6. Use the air flow control knob to control the atomizing air flow.
7. Use the air input adjustment knob to control the volume of air input.
8. Turn the air nozzle to achieve either a horizontal or vertical fan spray.
9. Lock the nozzle in place with the retaining ring.
Operation

fig.1
05
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. Flush the spray gun through with clean solvent.
2. To wash off any paint that has accumulated on the spray gun use a bristle brush and
solvent.
3. With a dampened solvent rag wipe the outside of the spray gun.
4. 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 the
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. If you change the nozzle size, ensure the complete nozzle set is exchanged. Before
putting the paint needle in, insert the paint nozzle.
