1. SAFETY INSTRUCTIONS

3. AIR SUPPLY CONNECTION

fig.1

3.1. Air Supply

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 50psi and an air flow according to specification.

3.1.3. WARNING! Ensure the air supply is clean and does not exceed 50psi while operating the spray gun. Too high an air pressure and

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. Recommended hook-up procedure is shown in fig.1.

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.

Do not fit a quick change coupling directly to the spray gun. A leader hose should be fitted to the spray gun and then a quick change

coupling may then be used to connect the leader hose to the air line recoil hose. See fig.1 & 2.

fig.2

Familiarise yourself with this products application and limitations, as well as the specific potential hazards peculiar to the spray gun.

 WARNING! Disconnect the spray gun from the air supply before changing accessories, servicing or performing any maintenance.



Paint cup remains pressurised after gun is disconnected from air line. DO NOT pull the trigger, but depressurise by gently opening cup.

Maintain the spray gun in good condition (use an authorised service agent).

Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the warranty.

Locate the spray gun in an adequate working area for its function, keep area clean and tidy and free from unrelated materials and ensure

there is adequate ventilation and lighting.

Keep the spray gun clean for best and safest performance.

Ensure the air system is suitable to the spray gun air consumption, (see specifications).

Wear approved respiratory protection and safety eye goggles.

Wear appropriate protective overalls.

Keep children and unauthorised persons away from the working area.

When not in use ensure the air supply is turned off.

Avoid unintentional operation.

 DO NOT point spray gun at yourself, at other persons or animals.

 DO NOT carry by the air hose, or yank the hose from the air supply.

 DO NOT use the spray gun for any purpose other than for which it is designed.

 DO NOT allow untrained persons to operate the spray gun.

 DO NOT get the spray gun wet or use in damp or wet locations or areas where there is condensation.

 DO NOT operate gun if any parts are missing or damaged as this may cause failure or personal injury.

 DO NOT direct air from the air hose at yourself or others.

2. INTRODUCTION & SPECIFICATIONS

Original Language Version

FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE 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. Immerse the front end of the gun only in solvent. The solvent should just cover the fluid connection.

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

5.1.3. Do not immerse the entire gun in solvent as this will cause lubricants on the rubber seals to dissolve. Dirty solvent may also clog

narrow passages in the gun.

5.1.4. Flush the gun through with clean thinners.

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

5.2. Air nozzle, fluid nozzle and needle assembly

5.2.1. To clean the nozzles, soak them in solvent to dissolve any dried material then blow them clean with air. Handle all nozzles carefully

and do not make any alterations in the gun.

5.2.2. If you need to probe the holes in the nozzles, be sure to use a tool that is softer than brass; do not use metal instruments.

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

5.3. 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

you have the correct part, or unscrew, realign and try again. DO NOT use excessive force when re-assembling.

5.3.1. Lubricate the gun daily with a light machine oil.

5.3.2. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in.

5.3.3. To change the needle packing use the socket spanner provided. Note: Handle the teflon seal and self tensioning spring with care.

5. CLEANING & MAINTENANCE

4. OPERATING INSTRUCTIONS

4.1. For best results, make sure to handle the gun correctly. It 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 you to

accurately control the gun and material (fig.3).

4.2. Spray from a distance of about 150mm (6") to 250mm (10") 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) The atomizing air flow is controlled by using the regulator attached to the incoming air supply which should be capable of

supplying between 5 and 11cfm.

b) Use the adjustment knob (fig.4.4) to increase or decrease the amount of paint flowing in from the gravity feed pot.

c) The width of the spray can be adjusted using knob (fig.4.5).

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.4.1) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (fig.4.2).

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 as fig.4, 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.5).

VIEW OF PROBLEM POSSIBLE REASON FOR PROBLEM SOLUTION

Dried material in a dirty side port restricts passage of

air. Greater flow of air from the cleaner side port forces

a fan pattern in the direction of the clogged side.

Dissolve material in the side ports with thinner,

then blow the gun clean.

Do not poke into the opening with metal

instruments.

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.

Remove the air nozzle and wipe off fluid tip

using a rag dampened with thinner.

Tighten the air nozzle

A split spray or one that is heavy on each end of a fan

pattern and weak in the middle is usually caused by

too high an atomization air pressure or by attempting

to get too wide a spray with thin material.

Check supply pressure and reduce if over 50psi.

Adjust paint needle if required.

Check spray pattern on a test panel.

Dirt between the fluid nozzle seat and body or

loosely installed fluid nozzle will cause the gun to spit.

Remove the fluid nozzle, clean the back of the

nozzle and the nozzle seat in the gun body

using a rag dampened with thinner.

Replace the nozzle and secure it tightly against

the body.

Material bubbles

in paint cup.

Atomised air flowing through the paint channel to pot.

The paint nozzle is not tight enough.

Air nozzle is not completely screwed in.

The air inlet seal is defective or nozzle insert is

damaged.

Tighten, clean or replace parts accordingly.

6. TROUBLESHOOTING

A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. Soak these parts in a solvent

that will soften the dried material and remove with a brush or a cloth. Never use metal instruments to clean the air or fluid nozzles. These parts

are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle is damaged, the part must be

replaced before a perfect spray can be obtained.
