Important: To ensure that this equipment reaches you in first class condition, protective
coatings have been use. Flush the equipment through with a suitable solvent before use.
1. Attach air hose to connector (15). Recommended hose size 8 mm bore. The hose must be
conductive and electrical bond from the spray gun to earth should be checked with an
ohmmeter. A resistance of less than 10
2. Air supply should be filtered and regulated.
1. Mix coating material to manufacturers instructions.
2. Screw cup (19) to gun. Do not over tighten.
3. Place the filter (24) in the cup and fill to required level with paint, or use funnel (SRI-17) and
use paper filter. Screw on lid.
4. Turn needle adjusting screw (5) fully clockwise to shut off fluid (for setting up air supply
pressure).Turn spreader valve (6) counter-clockwise to fully open.
5. Attach air supply to gun and adjust inlet air pressure up to 2 bar (29psi) at the gun inlet with
the gun triggered. (pressure gauge attachments shown under Accessories are
recommended for this).
6. Turn needle adjusting screw anti-clockwise 2 turns to find the mid position.
7. Test spray. If the finish is too dry, reduce air flow by reducing inlet pressure. If finish is too
wet, reduce fluid flow by turning needle screw (5) clockwise. If atomisation is too coarse,
increase inlet air pressure. If too fine, reduce inlet pressure.
8. The pattern size can be reduced by turning spreader valve (6) clockwise.
9. Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven
coating.
10. The recommended spray distance is 75-150 mm (3"-6").
11. Spray edges first. Overlap each stroke a minimum of 50%. Move gun at a constant speed.
12. Always turn off air supply and relieve pressure when gun is not in use.
Air Flow Valve (17)
1. The air flow valve (17) is fitted to reduce the inlet pressure through the gun. Screw the
adjusting knob clockwise to reduce pressure.
