1. SAFETY

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

9Familiarise yourself with this products application and limitations, as well as the specific potential hazards peculiar to the spray gun.

Paint cup remains pressurised after gun is disconnected from air line.

9DO NOT pull the trigger, but release the pressure by gently opening cup.

9Maintain the spray gun in good condition (use an authorised service agent).

9Replace or repair damaged parts. Use recommended parts only. Non authorised parts may be dangerous and will invalidate the

warranty.

9Locate 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.

9Keep the spray gun clean for best and safest performance.

9Ensure the air system is suitable to the spray gun air consumption, (see specifications).

9Wear approved respiratory protection and safety eye goggles.

9Remove ill fitting clothing. Remove ties, watches, rings, and other loose jewellery, and tie back long hair.

8DO NOT operate gun if any parts are missing or damaged as this may cause failure or personal injury.

8DO NOT direct air from the air hose at yourself or others.

9When not in use switch the spray gun off, and disconnect from the air supply.

2. INTRODUCTION

Standard set-up and economy price make this spray gun ideal for applying various materials including adhesives, base coats and nishing

coats. Round/at fan control allows spray pattern to be adjusted for any job. Brass air cap with steel needle and nozzle. Alternative set-ups

4. AIR SUPPLY

4.1. Recommended hook-up g.1

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

4.1.2. You will require an air pressure of 45psi, and an air ow according to specication.

WARNING! Ensure the air supply is clean and does not exceed 45psi 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.

4.1.3. Drain the air tank daily. Water in the air line will ruin the paint nish and damage the spray gun.

4.1.4. Clean air inlet lter weekly.

4.1.5. 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 ttings must have the same inside dimensions.

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

4.2. 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

(g.1 and 2).

5. OPERATION

5.1. 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 nishing the stroke. This will enable accurate control of the gun and material

(g.3B).

5.2. 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 nish. To reduce

over-spray and obtain maximum efciency, spray with the lowest possible atomizing air pressure.

5.3. Controlling the fan spray and the uid.

a) Use the needle (paint) adjustment knob (g.4.2) to adjust the amount of paint ow.

b) The atomizing air ow is controlled by the control knob (g.4.1).

c) The volume of air input is controlled by the adjustment knob (g.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 (g.4.4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (g.4.5).

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

the nozzle are horizontal (g.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 (g.6).

6. CLEANING/MAINTENANCE

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.

6.1. CLEANING THE GUN

6.1.1. Flush the gun through with clean solvent.

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

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

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

6.1.5. 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.

6.1.6. Adjust the uid needle valve so that when the gun is triggered, air ow occurs before uid ow.

6.2. MAINTENANCE

6.2.1. 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.

6.2.2. When changing the nozzle size, ensure the complete nozzle set is tted. This consists of air cap, uid nozzle and paint needle.

Insert the uid nozzle before paint needle.

7. TROUBLESHOOTING

A faulty spray is usually caused by improper cleaning or dried material around the uid 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 uid nozzle are damaged, they

must be replaced before a perfect spray can be obtained.

Problem Possible Cause Solution

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.

Dissolve material in the side ports with solvent, then

blow the gun clean. Do not poke into the nozzles

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 solvent. Tighten the air nozzle.

Material too thin or atomization air pressure too high. Regulate material viscosity or reduce air pressure.

Paint spray ‘utters’

Not enough paint in bottle.

Nozzle set / seating dirty, damaged or loosely

installed.

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.

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.
