Preventative Maintenance - DeVilbiss FLG-S5-18 Operación Manual

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 (18). 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. Attach the cup lid assembly (37) to the fluid inlet connector (27).
3. Position the yoke at right angles to the gun with the cam lever (31) to the front (see picture).
Make sure the vent hole in the lid is positioned under the yoke and the hole in the diaphragm
(KR-115) if fitted is 180° to the lid vent hole.
1. Mix coating material to manufacturers 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 to the lid assembly.
4. Turn needle adjusting screw (18) clockwise to prevent movement.
5. Turn spreader valve (10) counter-clockwise to fully open.
6. Adjust inlet air pressure (For recommended figures see Specifications) at the gun inlet with the
gun triggered. (pressure gauge attachment shown under Accessories is recommended for this).
7. Turn needle adjusting screw counter clockwise until first thread shows.
8. Test spray. If the finish is too dry reduce air flow by reducing air inlet pressure or by the air flow
valve (22). Screw the adjusting knob in to reduce pressure.
9. If finish is too wet reduce fluid flow by turning needle screw (18) clockwise or reducing the fluid
pressure. If atomisation is too coarse, increase inlet air pressure. If too fine reduce inlet
pressure.
10. The pattern size can be reduced by turning adjusting valve (10) clockwise.
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.
1. Turn off air and relieve pressure in the supply lines, or if using QD system, disconnect from
airline.
2. Release cup and raise the tube out of the material. Trigger the gun and allow material to drain
back into the cup. Dispose of the surplus material.
3. Clean the cup. Remove the drip-free diaphragm (if fitted) and clean. Replace the diaphragm if is
split or damaged.
4. Check the breather hole in the lid is not blocked.
5. Remove air cap (2) and clean. If any of the holes in the cap are blocked with coating material
only use the cleaning Kit KK-4584 (see Accessories) which has the correct tools for this or a
toothpick to clean. Using any other tool could damage the cap and produce distorted spray
patterns.
6. Ensure the tip of the nozzle (3) is clean and free from damage. Build-up of dried paint can distort
the spray pattern.
7. Lubrication – trigger stud (24), needle (16) and air-valve spindle (13) should be oiled each day.
