INSTALLATION

Important: To ensure that this equipment reaches you in first class condition, protective coatings have been used. Flush the equipment through with a suitable solvent before use.

1.Attach air hose to connector (13). Recommended hose size 8 mm bore. The hose must be conductive and electrical bond from the spraygun to earth should be checked with an ohmeter. A resistance of less than 106 Ohms is recommended.

2.Air supply should be filtered and regulated.

3.Attach Cup assembly (22) by screwing into the Fluid Inlet of the spraygun. Tighten with a wrench.

OPERATION

1.Mix coating material to manufac- turers instructions.

2.Fill the cup with the required amount of material. Fill to no more than 25mm (1") from the top of the cup.

DO NOT OVERFILL.

3.Attach Cup Lid.

4.Turn needle adjusting screw (7) clockwise to prevent movement.

5.Turn spreader valve (5) counter- clockwise to fully open.

6.Adjust inlet air pressure (For recom- mended figures see Specifications) at the gun inlet with the gun trig- gered. (pressure gauge attachment shown under Accessories is recom- mended for this).

7.Turn needle adjusting screw counter clockwise until first thread shows.

8.Test spray. If the finish is too dry reduce airflow by reducing air inlet pressure or by the optional Airflow Valve (14). Screw the Adjusting Knob (14) in to reduce pressure.

9.If finish is too wet reduce fluid flow by turning needle screw (7) clock- wise. If atomization is too coarse, increase inlet air pressure. If too fine reduce inlet pressure.

10.The pattern size can be reduced by turning adjusting valve (5) clock- wise.

11.Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven coating.

12.The recommended spray distance is 150-200 mm (6"-8").

13.Spray edges first. Overlap each stroke a minimum of 50%. Move gun at a constant speed.

14.Always turn off air supply and relieve pressure when gun is not in use.

PREVENTATIVE MAINTENANCE

1.Turn off air and relieve pressure in the supply lines, or if using QD system, disconnect from airline.

2.Remove Cup Lid (20) and empty coating material into a suitable container. Clean the gun and cup, preferably in a gun wash machine. Clean the cup.

3.Check the breather hole in the Lid and the Drip Check Lid is not blocked.

4.Remove air cap (1) and clean. If any of the holes in the cap are blocked with coating material use a toothpick to clean. Never use metal wire which could damage the cap and produce distorted spray patterns

5.Ensure the tip of the nozzle (2) is clean and free from damage. Build up of dried paint can distort the spray pattern.

6.Lubrication – stud/screw (6), needle

(9) and air valve (11) should be oiled each day.

REPLACEMENT OF PARTS

Nozzle (2) and Needle (9) – Remove parts in the following order: 7, 8, 9, 1 and 2. Replace any worn or damaged parts and

re-assemble in reverse order. Recommended tightening torque for nozzle (2) 9.5-12 Nm (80-100 lbf in).

Packing – Remove parts 7, 8, 9. Unscrew cartridge (4). Fit new cartridge finger tight. Re-assemble parts 9, 8, and 7 and tighten cartridge (4) with spanner suffi- cient to seal but to allow free movement of needle. Lubricate with gun oil.

Air Valve Seal Kit (16) – (Refer to photos 1 to 28 and fig 2)

Spreader valve (5) – Caution: always ensure that the valve is in the fully open position by turning screw fully counter- clockwise before fitting to body.
