1. SaFety
9 Familiarise yourself with the application, limitations and potential hazards peculiar to the spray gun.
WARNING! disconnect the spray gun from the air supply before changing accessories, servicing or performing any maintenance.
8 Paint cup remains pressurised after gun is disconnected from air line. dO nOt pull the trigger, but de-pressurise by gently opening cup.
9 Maintain the spray gun in good condition (use an authorised service agent).
9 Replace or repair damaged parts. Use authorised parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
9 Keep the spray gun clean for best and safest performance.
9 ensure that the compressed air system can supply the spray gun air consumption for the model to be used.

and an impervious hooded coverall.
9 Remove ill-fitting clothing. Remove ties, watches, rings and other loose jewellery and tie back long hair.
9 locate the spray gun in a suitable work area. Keep area clean and tidy and free from unrelated materials and ensure that there is
adequate ventilation and lighting.
9 Keep children and unauthorised persons away from the work area.
9 When not in use, ensure that the air supply is turned off.
9 Avoid unintentional operation of spray gun.
9 The spray gun has been treated with an anti-corrosive agent at the factory and MUST be flushed out thoroughly with thinner before use.
8 dO nOt point spray gun at yourself, other persons or animals.
8 dO nOt direct air from the air hose at yourself, other persons or animals.
8 dO nOt carry the spray gun by the hose, or yank the hose from the air supply.
8 dO nOt exceed the working pressure of 50psi (3bar).
8 dO nOt use the spray gun for any purpose other than that for which it is designed.
8 dO nOt allow untrained persons to operate the spray gun.
8 dO nOt get the spray gun wet or use in damp or wet locations or in areas where there is
condensation.
8 dO nOt operate the spray gun if any parts are missing or damaged as this may cause
failure and/or personal injury.
9 When not in use, disconnect the spray gun from the air supply, clean thoroughly and store
safely.
2. intrOductiOn

3. SpeciFicatiOn
Standard Set Up: ........................................................2.0mm
Available Set-Up(s): ...................................... 1.2, 1.4, 1.8mm
Recommended Air Pressure: ........................................ 50psi
Air Consumption: ......................................................7-14cfm
4. air Supply cOnnectiOn
4.1. air Supply
4.1.1. Ensure spray gun air valve (or trigger) is in the “o” position before connecting to the air supply.
4.1.2. You will require an air pressure of 50psi and an air ow according to specication.
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.
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. Recommended hook-up procedure is shown in g.1.
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.
4.2.1. do not t a quick change coupling directly to the spray gun. A leader hose should be tted 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 g.1 & 2.
g.1
g.2
5. OperatiOn
5.1. 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 nishing the stroke. This will enable you to
accurately control the gun and material (g.3).
5.2. 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 nish. To reduce over
spray and obtain maximum eciency, spray with the lowest possible atomizing air pressure.
5.3. Controlling the fan spray and the uid.
A) The atomizing air ow is controlled by knob (g.4.1).
b) Use the needle adjustment knob (g.4.2) to increase or decrease the amount of paint ow.
C) The width of the spray can be adjusted using 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 as g.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 (g.5).

disconnect from the air supply before attempting any cleaning or maintenance.
6.3.1. Immerse the front end of the gun only in solvent. The solvent should just cover the uid connection.
6.3.2. Use a bristle brush and solvent to wash o accumulated paint.
6.3.3. 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.
6.3.4. Flush the gun through with clean thinners.
6.3.5. Wipe the outside of the gun with a dampened solvent rag.
6.3.6. Air nozzle, uid nozzle and needle assembly
6.3.7. 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.
6.3.8. 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.

6.3.9. Adjust the uid needle valve so that when the gun is triggered, air ow occurs before uid ow.
6.1. Further cleaning hints and tips
6.1.1. When cleaning with a cup, a compatible solvent should be siphoned through the gun by inserting the tube from the siphon cup in a
open container of solvent. Trigger the gun intermittently to thoroughly ush passageways and internal parts.
7. maintenance
7.1.1. Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check
that you have the correct part, or unscrew, realign and try again. dO nOt use excessive force when re-assembling.
7.1.2. lubricate the gun daily with a light machine oil.
7.1.3. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in.
7.1.4. To change the needle packing use the socket spanner provided. Note: Handle the Teon seal and self tensioning spring with care.
8. trOuBle ShOOtinG
A faulty spray is usually cause by improper cleaning or dried material around the uid 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 uid nozzles. These parts
are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or uid nozzle is damaged, the part must be
replaced before a perfect spay can be obtained.
Problem Possible Causes Solution
Paint spray utter
Material bubbles or “boils” in paint cup
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.
Atomised air flowing through the paint channel to
the bottle. The paint nozzle is not sufficiently tight.
Air nozzle is not completely screwed on.
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.
Tighten, clean or replace parts accordingly.
