Manual de Instrucciones y Lista de Piezas Pistola Pulverizadora HVLP Alimentada por Gravedad 34 FAN DIRECTION The direction of the fan (horizontal or vertical) can be changed by loosening the lock ring and turning the air cap 90 degrees (See Figure 3). Hand tighten lock ring after adjustment. PATTERN ADJUSTMENT 1. Adjust air pressure to the spray gun according to the recommendations supplied with the spray material. This air pressure usually falls between 40 - 60 psi. Do not exceed spray gun maximum pressure. Adjust air pressure with the trigger pulled and air control knob (if applicable) fully open. If reduced air pressure is desired for some areas of the spray job, use the air compressor regulator or air control knob to reduce pressure as necessary (See Figure 4). 2. Set pattern size to desired shape. For full pattern, open pattern control knob by turning counterclockwise. For a round pattern, turn pattern control knob clockwise (See Figure 5). 3. Turn fluid control knob fully clockwise until closed (See Figure 5). 4. Trigger a short burst while turning fluid control knob counterclockwise. Observe the spray pattern on the target and adjust the fluid control knob until the desired pattern (atomization) is obtained (See Figure 6). If the spray is too fine (excessive overspray), caused by too much air for the amount of paint being sprayed, reduce the air pressure or open the fluid control to spray more material. If the spray is too coarse (spitting globs), reduce the amount of material with the fluid control knob or thin the paint. 5. The fluid control knob can be used to finely adjust pattern consistency. Before spraying the workpiece, practice a few minutes on a cardboard target to ensure the pattern size and consistency are set correctly. Operation 1. Begin spraying. Always keep the gun at right angles to the work (See Figure 8). 2. Keep the nozzle about 6 to 9 inches from the work surface throughout the stroke and always keep the gun WATER/OIL IN COMPRESSED AIR All compressor pumps discharge some condensed water, oil or contaminates with the compressed air. IMPORTANT: This condensation will cause “fish eyes” to appear in the paint job. Install appropriate water/oil removal equipment and controls as necessary for the intended application. Locate filter as close to spray gun as possible. Failure to install appropriate water/oil removal equipment may result in damage to machinery or workpiece.

Stopping gun movement in mid-stroke will cause a build up of paint and result in runs. Do not fan the gun from side to side while painting. This will cause a build-up of paint in the center of the stroke and an insufficient coating at each end (See Figure 9). Heavy coat Thin coat Thin coat INCORRECT Figure 9 3. Trigger the gun properly. Start the gun moving at the beginning of the stroke BEFORE SQUEEZING THE TRIGGER and release the trigger BEFORE STOPPING GUN MOVEMENT at the end of the stroke. This procedure will feather (blend) each stroke with the next without showing overlap or unevenness (See Figure 10). 6 - 9” Release Trigger Pull Trigger Start Stroke End Stroke Figure 10 4. The amount of paint being applied can be varied by the speed of the stroke, distance from the surface and adjustment of the fluid control knob. 5. Overlap strokes just enough to obtain an even coat (See Figure 11). Figure 11 NOTE: Two thin coats of paint will yield better results and have less chance of runs than one heavy layer. 6. Use a piece of cardboard as a shield to catch overspray at the edges of the work to protect other surfaces. Use masking tape to cover other areas if needed. HVLP Gravity Feed Spray Gun Maintenance DAILY CLEAN-UP Local codes may require specific cleaning methods and equipment. Follow local codes and paint manufacturer’s recommendations for the use and disposal of spray materials and solvent. Clean spray gun immediately after use. Paint and other materials dry quickly in the small passages rendering gun useless due to the difficulty of removing hardened paint from the passages inside the gun. NOTE: In the instructions below, the use of the word...
