A minimum of 100 feet of hose should be used. b. Adjust the Engine Speed and Pump Pressure. First set the throttle lever to the maximum RPM setting (fully left). Trigger the gun onto a test paper to check the spray pattern and atomization. Adjust the Pressure Control Knob until you get a good pattern. Reduce RPM of engine to support pressure without overworking engines. 7. Clean tip if clogged. If tip is becoming worn, replace it. Worn tips waste paint, cause overspray, make cutting-in difficult, and decrease sprayer performance. IMPORTANT: Always follow the Pressure Relief Procedure on page 3 before servicing unit. Never hold your ! WARNING hand, body, fingers, or hand in a rag in front of the spray tip when cleaning or checking it for a cleared tip. Always point the gun toward the front or into a waste container when checking to see if the tip is cleared or when using a self- cleaning tip. a. Follow the Pressure Relief Procedure on page 3. b. Clean the front of the tip frequently (with toothbrush only) during the day to keep material from building up and clogging the tip. c. To clean and clear a tip if it clogs, refer to the separate instruction manual received with your gun and nozzle. NOTE: When pausing during a paint job, keep tip clean by locking the gun and submerging the tip in a small bucket of paint thinner. This will help reduce buildup and drying of paint in tip, tip guard, and gun. Clean a clogged NOTICE standard flat tip only after it has been removed from the gun. Follow the Pressure Relief Procedure on page 3. 8. When shutting off the sprayer, follow this procedure. a. Whenever you stop spraying, even for a short break, follow the Pressure Relief Procedure on page 3. b. Clean the tip and gun as recommended by your separate gun instruction manual. c. Flush the sprayer at the end of each work day if the material you are spraying is water-based, or if it could harden in the sprayer overnight. See "Flushing" on page 4. Use a compatible solvent to flush, then fill the pump and hoses with an oil based sovent such as mineral spirits. 7 Operating Instructions and Parts Manual AL2810 Airless Paint Systems Operation (Cont.) d. For long term shutdown or storage, refer to page 4. Be sure to relieve ! WARNING pressure in the pump after filling with mineral spirits. SPRAY TECHNIQUE Good Spray Gun Technique is at the core of any spray paint operation. Operator skill and efficiency is as important as good equipment and good paint. Good spray technique is a skill that can be developed by following these simple instructions. If you are not familiar with spraying techniques, study this section of your manual and practice the proper technique on pieces of cardboard or a suitable surface. Hold the spray gun 12 - 15 inches away from the work surface and keep it perpendicular (straight) to the surface. Move the spray gun parallel to the work and at a right angle to the surface. (See Figure 6). Move the gun at a steady rate in order to apply a good coverage. The wet coat should be just under the thickness at which a run or sag will occur. Slow gun movement or gun held too close will result in an overly wet or thick wet or thick coat coverage that is likely to run or sag. Do not wave the spray gun. This waving is called arching. Instead, hold the spray gun at a 12 to 15 inch distance perpendicular from the work. (See Figure 7.) The closer the spray gun is held to the work, the thicker the paint is deposited and the faster the gun must be moved to prevent sags and runs. Holding the gun too far from the work will cause excessive fog, overspray, and a thin and grainy coat. It is important to "trigger" the gun after gun movement (arm movement) has started and release trigger (shut gun off) before gun movement ends. Gun movement is always longer than actual paint (spray) stroke. In that manner, even blending and uniform paint coat thickness is achieved over the entire surface. When the gun is in motion as the trigger is pulled, it deposits an even amount of paint. Overlap the previous pass by half the width of the spray pattern. Aim at the bottom of the previous pass. Adjust Pressure Control Knob so that paint is completely atomized from the spray gun. Insufficient pressure will result in “tailing.” Too much pressure RIGHT WRONG Gun is held at an angle, fluid disperses unevenly Gun is held perpendicular to work piece, fluid disperses evenly Figure 6 - How to hold spray gun when spraying 12-15” Figure 7 - Proper Spray Technique INCORRECT CORRECT Start Pull Trigger Release Trigger End will result in excess fog and overspray, excessive tip wear, and increased sprayer wear and tear. Always use the lowest pressure possible to obtain desirable results. Test the spray pattern on a piece of cardboard or other surface. To cover “inside” and “outside” corners (on walls or other objects), aim the spray gun toward the center of the corner. The spray pattern is divided in half, and the edges of the spray pattern on bo...
