3.1. Air Supply

Recommended hook-up is shown in Fig.1.

3.1.1. Ensure spray gun air valve (or trigger) is in the off position before connecting to the air supply.

3.1.2. You will require an air pressure of 43psi, and an air flow according to specification.

3.1.3. WARNING! Ensure the air supply is clean and does not exceed 43psi while operating the spray gun. Too high an air pressure and/or

unclean air will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.

3.1.4. Drain the air tank daily. Water in the air line will ruin the paint finish and damage the spray gun.

3.1.5. Clean air inlet filter weekly.

3.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be

1/4” I.D. and fittings must have the same inside dimensions.

3.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.

3.2. Couplings

Vibration may cause failure if a quick change coupling is connected directly to the spray gun. To overcome this, connect a leader hose to

the spray gun. A quick change coupling may then be used to connect the leader hose to the air line recoil hose (Figs.1 and 2).

4.1. For best results, the gun should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke before

squeezing the trigger and release the trigger before finishing the stroke. This will enable accurate control of the gun and material (Fig.3B).

4.2. Spray from a distance of about 6 to 10 inches (150 to 250mm) depending on the material and the atomizing pressure. The material

deposited should always be even and wet. Each stroke must overlap the preceding stroke to obtain a uniform finish. To reduce over-spray

and obtain maximum efficiency, spray with the lowest possible atomizing air pressure.

4.3. Controlling the fan spray and the fluid.

a) Use the needle (paint) adjustment knob (Fig.4.2) to adjust the amount of paint flow.

b) The atomizing air flow is controlled by the control knob (Fig.4.1).

c) The volume of air input is controlled by the adjustment knob (Fig.4.3).

d) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.

e) Turn the air nozzle (Fig.4.4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (Fig.4.5).

The spray pattern of the gun is variable from round to flat with all patterns in between. In normal operation, the wings on the

nozzle are horizontal (Fig.5). This provides a vertical fan-shaped pattern which gives maximum, uniform and even coverage when

moving the gun back and forth, parallel to the work surface (Fig.6).

3. AIR SUPPLY

4. OPERATION

FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE SPRAY GUN IS CORRECTLY CLEANED AFTER EACH USE.

Disconnect from the air supply before attempting any cleaning or maintenance.

5.1. Cleaning the gun

5.1.1. Flush the gun through with clean solvent.

5.1.2. Use a bristle brush and solvent to wash off accumulated paint.

5.1.3. Clean the air nozzle using a brush. Blow clean with air. Handle all nozzles carefully and do not make any alterations in the gun.

5.1.4. Wipe the outside of the gun with a dampened solvent rag.

5.1.5. If there is a need to probe the holes in the nozzles, ensure a tool that is softer than brass is utilised, under no circumstances use a

metal tool, as the slightest amount of damage will adversely affect the spray pattern.

5.1.6. Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.

5.2. Maintenance

Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check that

it is the correct part, or unscrew it, realign and retry. DO NOT use excessive force when re-assembling.

5.2.1. When changing the nozzle size, ensure the complete nozzle set is fitted. This consists of air cap, fluid nozzle and paint needle. Insert the

fluid nozzle before paint needle.

Dried material in a side port restricts passage of air.

Greater flow of air from the clean side port forces a fan

pattern in the direction of the clogged side.

Dried material around the outside of the fluid nozzle tip

restricts the passage of atomizing air at one point

through the centre opening of the air nozzle and results

in the pattern shown. This pattern can also be caused

by a loose air nozzle.

Material too thin or atomization air pressure too high.

Not enough paint in bottle.

Nozzle set / seating dirty, damaged or loosely installed.

Material bubbles or “boils” in paint

cup.

Atomised air flowing through the paint channel to the

bottle. The paint nozzle is not sufficiently tight.

Air nozzle is not completely screwed on.

Tighten, clean or replace parts accordingly.

Dissolve material in the side ports with solvent, then blow the gun

clean. Do not poke into the nozzles with metal instruments.

Remove the air nozzle and wipe off fluid tip using a rag dampened

with solvent. Tighten the air nozzle.

Regulate material viscosity or reduce air pressure.

Refill bottle. Remove the fluid nozzle, clean the back of the nozzle

and the nozzle seat using a cloth dampened with thinner. Refit the

nozzle and secure it tightly against the body.

If necessary replace nozzle set.

PROBLEM POSSIBLE CAUSES SOLUTION

A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. If cleaning is required, remove

these parts and soak them in solvent. This will soften the dried material which can then be removed with a brush or a cloth.

These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle are damaged, they

must be replaced before a perfect spray can be obtained.
