4. Configuració
Una configuració adequada és crucial per a un rendiment i una seguretat òptims.
- Preparar la zona de treball: Ensure the painting area is clean, well-ventilated, and free from dust and contaminants. Use drop cloths or masking to protect surrounding surfaces.
- Connecteu el subministrament d'aire: Attach the air adjusting valve with gauge to the spray gun's air inlet. Connect a clean, dry air hose from your compressor to the air adjusting valve. Ensure your air compressor can provide sufficient CFM (Cubic Feet per Minute) and PSI (Pounds per Square Inch) for the chosen spray gun (refer to specifications). An air dryer/filter is highly recommended to prevent moisture and oil from entering the paint.
- Preparació del material: Mix your paint or primer according to the manufacturer's instructions. Strain the material to remove any particles that could clog the gun. Fill the appropriate cup (600cc for primer/finish, 100cc for touch-up) with the prepared material. Do not overfill.
- Attach Cup: Securely attach the filled material cup to the spray gun.
- Initial Air Pressure Setting: With the air supply connected and the gun not spraying, set the air pressure at the gun's inlet using the included gauge. Refer to the specifications section for recommended inlet pressures for each gun type.
5. Instruccions de funcionament
Achieving a professional finish requires understanding the spray gun's adjustments and proper technique.
5.1 Ajustaments
- Botó de control de fluids: Located at the back of the gun, this knob controls the amount of material flowing through the gun. Turn clockwise to decrease fluid, counter-clockwise to increase.
- Botó de control del patró del ventilador: Typically located on the side of the gun, this knob adjusts the shape of the spray pattern from round to wide fan. Turn clockwise for a narrower pattern, counter-clockwise for a wider pattern.
- Cap d'aire: The air cap determines the atomization and pattern. Ensure it is clean and correctly oriented.
5.2 Tècnica de polvorització
- Spray de prova: Always perform a test spray on a piece of scrap material to check the pattern, atomization, and fluid output before painting your actual workpiece. Adjust settings as needed.
- Distància: Maintain a consistent distance from the surface, typically 6-8 inches (15-20 cm), depending on the material and desired finish.
- Moviment: Move the gun parallel to the surface in smooth, even strokes. Overlap each pass by about 50% to ensure uniform coverage.
- Control del disparador: Fully depress the trigger at the beginning of each stroke and release at the end. Avoid fanning the gun at the wrist, which can lead to uneven coverage.
- Capes múltiples: Apply multiple thin coats rather than one thick coat to prevent runs and sags. Allow appropriate flash-off time between coats as recommended by the paint manufacturer.
6. Manteniment
Regular cleaning and maintenance will extend the life of your spray guns and ensure consistent performance.
- Neteja immediata: Clean the spray gun immediately after each use. Disconnect the air supply and empty any remaining material from the cup.
- Flush the Gun: Pour appropriate cleaning solvent (e.g., lacquer thinner for solvent-based paints, water for water-based paints) into the cup and spray it through the gun until it runs clear.
- Desmuntar i netejar: Disassemble the air cap, fluid tip, and needle. Use the provided cleaning brushes and solvent to thoroughly clean all components. Pay special attention to the small holes in the air cap. Never use metal objects to clean the fluid tip or air cap as this can damage them.
- Clean the Cup: Wash the material cup thoroughly with solvent and a brush.
- Lubricació: Apply a small amount of spray gun lubricant to the needle packing and air valve packing after cleaning to ensure smooth operation and prevent wear.
- Reassembly and Storage: Reassemble the gun carefully, ensuring all parts are tightened correctly. Store the gun in a clean, dry place, preferably hanging to prevent damage to the fluid tip.
