1. SAFETY INSTRUCTIONS
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.
Ensure spray gun is well maintained and kept 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.
Keep the spray gun thoroughly clean for best and safest performance.
Ensure that the compressed air system can supply the spray gun air consumption (12 to 15cfm).
Wear approved safety respiratory protection and safety eye goggles.
If spraying isocynate based finisher, wear approved respirator/clean air breathing apparatus and cover exposed skin with latex gloves and an
impervious hooded coverall.
Remove ill-fitting clothing. Remove ties, watches, rings and other loose jewellery and tie back long hair.
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.
Keep children and unauthorised persons away from the work area.
When not in use, ensure that the air supply is turned off.
Avoid unintentional operation of spray gun.
DO NOT point spray gun at yourself, other persons or animals.
DO NOT direct air from the air hose at yourself, other persons or animals.
DO NOT carry the spray gun by the hose, or pull the hose from the air supply.
DO NOT exceed the maximum air pressure of 70psi.
DO NOT use the spray gun for any purpose other than that 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 in areas where there is condensation.
DO NOT operate the spray gun if any parts are missing or damaged, as this may cause failure and/or personal injury.
When not in use, disconnect the spray gun from the air supply, clean thoroughly before storing in a safe, dry, childproof location.

3.1. Recommended hook-up procedure 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. The spray gun requires an air pressure of at least 30psi, and an air flow according to specification.
3.1.3. WARNING! Ensure the air supply is clean and does not exceed 70psi whilst 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 ¼” 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. See 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.3).
4.2. Spray from a distance of about 150 to 250mm (6 to 10 inches) depending on the material and the atomising 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 atomising air pressure.
4.3. Controlling the fan spray and the fluid.
a) Use the needle (paint) adjuster (fig 4.2) to increase or decrease the amount of paint flow.
b) The atomising air flow is controlled by the spray width adjuster (fig.4.1). The volume of air input is controlled by the air adjuster (fig.4.3).
c) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.
d) Turn the nozzle (fig4.4) to achieve a horizontal or vertical fan spray. Lock the nozzle with the 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 as in fig.5. This provides a vertical fan-shaped pattern which gives maximum uniform, even coverage when
moving the gun back and forth, parallel to the work surface.
