1. SAFETY
9Familiarise yourself with the application and limitations, as well as the potential hazards of the spray gun.
WARNING! Disconnect the spray gun from the air supply before changing accessories, servicing or performing any maintenance.
9Ensure spray gun is well maintained and kept in good condition (use an authorised service agent).
9Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
9Locate 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.
9Keep the spray gun clean for best and safest performance.
9Ensure that the air system has sufficient output for the spray gun air consumption (see specification).
9Wear approved respiratory protection, safety eye goggles and skin protection.
9Remove ill fitting clothing. Remove ties, watches, rings and other loose jewellery and tie back long hair.
9Keep children and unauthorised persons away from the work area.
9When gun is not in use ensure that the air supply is disconnected.
9If spraying isocynate based finisher, wear approved respirator/clean air breathing
apparatus and cover exposed skin with latex gloves and an impervious hooded
coverall.
9Avoid unintentional operation.
8DO NOT paint were there is any source, or possible source, of ignition as paint
mist is extremely flammable.
8DO NOT point spray gun at yourself or at other persons or animals.
8DO NOT carry the gun by the air hose, or yank the hose from the air supply.
8DO NOT use the spray gun for any purpose other than that for which it is
designed.
8DO NOT allow untrained persons to operate the spray gun.
8DO NOT get the spray gun wet or use in damp or wet locations or areas where
there is condensation.
8DO NOT operate gun if any parts are missing or damaged as this may cause
failure and/or personal injury.
8DO NOT direct air from the air hose at yourself or others.
8When not in use switch off the air supply and disconnect the spray gun.

4. AIR SUPPLY
4.1. Ensure that the air valve is in the “off” position before connecting to the air supply.
4.2. The spray gun will require an air pressure of approximately 60psi and an air volume of more than 12cfm.
WARNING! Ensure the air supply is clean does not exceed 90psi. Too high an air pressure and unclean air will shorten
the life of the gun due to excessive wear and may be dangerous, causing damage and/or personal injury.
4.3. Drain the air supply tank daily. Water in the air line will damage the gun and contaminate the paint.
4.4. Clean the compressor air inlet filter weekly. For recommended hook-up, see diagram.
4.5. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose bore should
be 10mm and fittings must have the same inside dimensions.
4.6. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.

5. PREPERATION
5.1. The gun was treated with an anti-corrosion agent to protect it prior to first use. Before first use make sure that the gun is flushed
with paint solvent to remove the agent.
WARNING! Solvents and cleaning agents based on halogenated hydrocarbons, e.g. 1.1.1-trichlorethylene and methylene chloride, may
have a chemical reaction with the aluminium components of the gun. In extreme cases the reaction can be explosive. Therefore, use
only solvents/cleaning agents which DO NOT contain these substances.
6. OPERATION
Ensure that you have read and understood the safety instructions in Section 1 and the warning in Section 4.
6.1. For best results the gun must be handled and operated 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 paint (fig.1).
6.2. Spray from a distance of about 6 to 10 inches depending on the material and the atomizing pressure. The paint 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 effective atomizing air pressure.
6.3 Controlling the fan spray and the paint:
a) Use the paint control knob (fig.2.B) to increase or decrease the paint flow.
b) The air input control (fig.2.C) should be set to the lowest effective flow.
c) Turn the air cap (fig.3.1) to achieve a horizontal or vertical fan spray. Lock the cap with retaining ring (fig.3.2).
d) The spray pattern is variable from round to flat with all patterns in between, controlled by the pattern knob (fig.2.A).
e) In normal operation, the wings on the cap are horizontal as (fig.3). This provides a vertical fan-shaped pattern (fig.4) which gives
optimum coverage when moving the gun back and forth, parallel to the work surface.

7. MAINTENANCE
7.1 CLEANING
7.1.1. IT IS VERY IMPORTANT TO ENSURE THAT THE GUN IS CORRECTLY CLEANED AFTER EACH USE
7.1.2. Disconnect from the air supply before attempting any cleaning, other than flushing, or maintenance.
7.1.3. Flush the gun thoroughly with solvent and clean the nozzle with solvent and a brush. DO NOT immerse/soak the nozzle in
solvent.
8DO NOT immerse the entire gun in solvent. This will cause lubricants to dissolve and packing to dissolve or dry out.
7.1.4. Wipe the outside of the gun with a solvent-dampened rag.
7.1.5. If you need to clear blocked orifices, be sure to use a probe that is softer than brass.
7.2 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.
7.2.1. Lubricate the gun daily with a light machine oil. Be sure to lubricate the fluid needle packing, air valve packing and trigger pivot point.
7.2.2. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in.
8. TROUBLESHOOTING
A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air cup - use a brush and solvent
to remove. Never use metal instruments to clean the air cup or paint nozzle. These parts are carefully machined and any damage to them
will cause a faulty spray. If either the air cup or paint nozzle is damaged, the part must be replaced before a perfect spay can be obtained.
PROBLEM POSSIBLE CAUSES 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.
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 cup and results in
the pattern shown. This pattern can also be caused by a
loose air cup.
A split spray or one that is heavy at each end of the 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 paint.
Tighten, clean or replace parts accordingly.
1. Worn needle packing permits air to get into the fluid
passageway. This results in spitting.
2. Dirt between the paint nozzle seat and body or a loose
paint nozzle will cause the gun to spit.
3. A loose or defective joint between the pot and gun can
cause spitting.
Atomised air flowing through the paint channel to
the bottle. The paint nozzle is not sufficiently tight.
Air nozzle is not completely screwed on.
Material bubbles
or “boils” in paint cup.
Dissolve material in the side ports with solvent,
then blow the gun clean. Do not poke into the
nozzles with metal instruments.
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.
1. Tighten the packing screw or, in severe cases,
replace the packing.
2. Remove the fluid nozzle, clean the back of the
nozzle and the nozzle seat in the gun body
using a rag dampened with solvent.
3. Tighten or replace.
Remove the air cup and wipe off fluid tip using a
rag dampened with solvent. Tighten the air cup.
