Prevent Clogging: Shake paint bottle vigorously for 30 to 60 seconds. You should hear the paint become a thinner and more fluid. Squeeze paint ONLY through the small opening in the flip top cap. This helps thin the paint and strain clumps. CLEANUP: Rinse cartridge, air tube, and nozzle to prevent dry clumps that can clog sprayer. Pressurize Sprayer: Pump handle 15 to 20 times for effective spray. Screw cartridge on snugly to ensure proper pressurization. Align the small arrows on the cartridge with those on the sprayer for a secure fit. IMPORTANT! Before removing the cartridge, hold the trigger and release any residual air. Spraying Best Practices: Be sure the nozzle is rinsed well with water to ensure that the tiny holes inside the nozzle are clear of paint. Make sure the front orange nozzle is screwed on tight. Spray downward toward the ground to create a continuous spray.
