[. . . ] Prepare the paint as instructed by the manufacturer. Strain the paint through a fine, nylon­mesh bag (available at most paint dealers) to remove particles that might clog the spray tip. This is probably the most important step toward trouble­free spray painting. Add solvent to old and remixed paints to replace the solvent lost through evaporation. Do not add too much solvent as thin paint is hard to control and doesn't cover very well. Follow the paint manufacturer's recommendations on thinning. 10 820-007 Setup 10. Put the suction tube into the paint container. Turn the pressure adjusting knob (B) all the way counterclockwise to lower the pressure setting. Keep the gun triggered until all air is forced out of the system and the paint flows freely from the gun. Release the trigger and lock the gun trigger safety. NOTE: If the pump is hard to prime, place a container under the drain valve and open it. Let the sprayer run until paint is running through the drain valve. This method bleeds the air from the pump. Then release the gun trigger safety and trigger the gun to prime the hose as instructed previously, under Prime the Sprayer. If any are found, follow the Pressure Relief Procedure, page 4, before tightening connections. d. Hold a metal part of the gun firmly against and aimed into a grounded metal waste container. Squeeze the trigger and hold it open, turn the ON/OFF switch to ON, and slowly increase the pressure setting until the sprayer starts. Adjust the Spray Pattern Increase the pressure adjusting knob setting just until spray from the gun is completely atomized. Use the lowest pressure necessary to get the desired results, which helps prolong the life of your sprayer and minimizes paint lost by overspray. Test the spray pattern on a piece of light colored paper. The tip position determines the direction of the pattern width. Before adjusting the pattern always follow the Pressure Relief Procedure Warning on page 4. Cleaning and Clearing the Spray Tip WARNING To reduce the risk of injection injury, DO NOT hold your hand, body, or a rag in front of the spray tip when cleaning or checking a clogged tip. Always point the gun toward the ground or into a waste container when checking to see if the tip is clear.
