Know Your Controls Know Your Controls The ON/OFF power switch controls the main power to your sprayer. The Pressure Control knob increases or decreases the pressure and flow of the paint. The Prime/Spray Valve directs the fluid to either the Drain Tube or the hose and gun. It is used to prime the sprayer, which means to evacuate the air out of the pump, hose, and gun. Your gun will not spray if there is air in the system.
Set Up Set Up Assemble Your Sprayer 1. Connect airless hose to airless hose connection (P) on sprayer. Use wrench to tighten securely. 2. Connect the other end of the hose to the gun. Use two wrenches to tighten securely to gun (see image below). 3. Assure Spray Tip is properly inserted into the Spray Tip Guard, and the Spray Tip Guard assembly is tightened securely to gun. See Spray Tip Installation, page 21. 4. Perform the Pressure Relief Procedure, page 14.
Start Up Start Up Pressure Relief Procedure 3. Turn pressure control knob to lowest setting. 4. Put Drain Tube into a waste pail and turn Prime/Spray Valve down to PRIME position to relieve pressure. 5. Hold the gun firmly to a pail. Point gun into pail. Disengage the trigger lock and trigger the gun to relieve pressure. 6. Engage the trigger lock. 7. If you suspect that pressure has not been fully relieved, see Blockages, page 17.
Start Up Flush Storage Fluid 7. Align setting indicator with the START setting on the pressure control knob. 8. Turn ON/OFF switch to ON position. 9. When sprayer starts pumping, flushing fluid will flow up the Suction Tube and out the Drain Tube. Allow fluid to flow out of Drain Tube, into waste pail, for 30 to 60 seconds. It is important that you flush storage fluid from the sprayer before using it. 1. Make certain ON/OFF switch is OFF. 2.
Start Up Strain the Paint Disposable paint strainer bags are used to remove coarse particles and debris from new or previously opened paint or stain, and are available where paint is sold. To avoid priming problems and Spray Tip clogs it is recommended to strain all paints and stains before spraying. Stretch a disposable paint strainer bag over a clean pail and pour the paint through the strainer. 2. Turn ON/OFF switch to ON position. 3. Wait to see paint coming out of Drain Tube. 4.
Start Up 4. Release trigger. Engage trigger lock. Refilling Paint Pail When the paint pail runs low and the gun stops spraying, refill the paint pail and repeat the Fill Pump (Prime Pump) procedure, then the Fill Gun and Hose procedure. You are now ready to spray! High-pressure spray is able to inject toxins into the body and cause serious bodily injury. Do not stop leaks with hand or rag. NOTE: It is normal for the motor to stop once the sprayer is primed and under pressure.
Spraying Spraying Start 1. Turn pressure control knob to START position. 2. Disengage trigger lock. Adjust Pressure Control To select a setting, align symbol on pressure control knob with setting indicator on sprayer. 1. For best spray results with lowest overspray, adjust pressure control to “START” setting. 2. Test the spray pattern on a test area or piece of cardboard. 3. If needed, increase Pressure Control Knob setting to minimum setting that results in an acceptable spray pattern.
Spraying Spray Techniques Use a piece of scrap cardboard to practice these basic spraying techniques before you begin spraying the surface. • Hold gun 12 in. (30 cm) from surface and aim straight at surface. Tilting gun to direct spray angle causes an uneven finish. • Flex wrist to keep gun pointed straight. Fanning gun to direct spray at angle causes uneven finish. Aiming Gun Aim center of spray of gun at bottom edge of previous stroke, overlapping each stroke by half.
Spraying Spray Tip and Pressure Selection Spray Tips come in a variety of sizes for spraying a wide range of materials. Your sprayer includes a 515 Spray Tip for use with most paints on large surfaces such as walls and ceilings. If you are spraying stain or need a different spray fan width, refer to the Spray Tip chart below to select the best Spray Tip for your project. Additional Spray Tip sizes are available where paint sprayers are sold. 1.
Spraying Clear Spray Tip Clog 2. Engage trigger lock. Rotate Spray Tip back to SPRAY position. Disengage trigger lock and continue spraying. SPRAY In the event that particles or debris clog the Spray Tip, the Spray Tip can be reversed to quickly and easily clear particles without disassembling the sprayer. See Strain the Paint, page 16 for additional information. 1. Engage trigger lock. Rotate Spray Tip to UNCLOG position.
Spraying a. Use Spray Tip to align gasket and seal in the Spray Tip Guard. c. 4. b. 22 Turn the arrow shaped handle on the Spray Tip forward to the SPRAY position. Screw Spray Tip Guard assembly onto the gun and tighten. Spray Tip must be pushed all the way into the Spray Tip Guard. Rotate Spray Tip while pushing down.
Cleanup Cleanup Cleaning the sprayer after each use results in a trouble free start up the next time the sprayer is used. 4. Separate Drain Tube (smaller) from Suction Tube (larger). ti27 7124a • For short term shutdown periods (overnight to two days), refer to Short Term Storage, page 28. • For cleanup after using water-based materials only (by use of a garden hose), refer to Cleanup with Power Flush Valve, page 25. • For cleanup from pails, refer to Cleaning from a Pail, below.
Cleanup 8. Turn Prime/Spray valve down to PRIME position. e. Continue to hold gun trigger until you see paint diluted with flushing fluid starting to come out of gun. 13. While continuing to trigger gun, quickly move gun to redirect spray into waste pail. Continue triggering gun into waste pail until flushing fluid dispensed from gun is relatively clear. 9. Turn ON/OFF switch to ON position. 10. Flush until approximately 1/3 of the flushing fluid is emptied from the pail. 11.
Cleanup Cleanup with Power Flush Valve 7. Screw Power Flush Valve (included with sprayer) to garden hose. Close Power Flush Valve. (Water-based materials only) 8. Turn on water. Open Power Flush Valve. Rinse paint off Suction Tube, Drain Tube and inlet screen. Close Power Flush Valve. 9. Unscrew inlet screen from Suction Tube. Place inlet screen in waste pail.

Call Us Toll-Free: 1-888-541-9788 1. 2. Follow Pressure Relief Procedure, page 14, before checking or repairing. Solutions at the beginning of each problem listed are the most common. Problem Motor does not run: (verify sprayer is plugged in, and ON/OFF switch is on) 36 or visit us at: www.magnum.graco.
Troubleshooting Problem Sprayer runs, but pump does not prime or looses prime while in use. (Pump cycles but does not pull paint into Suction Tube or build pressure.) Cause Solution Prime/Spray Valve is in SPRAY position. Turn Prime/Spray Valve down to PRIME position until paint exits Drain Tube. Inlet screen is clogged or Suction Tube is not completely immersed in paint. Clean debris off inlet screen and make sure Suction Tube is completely immersed in paint.
Troubleshooting Problem Pump is primed, but can not achieve good spray pattern. 38 Cause Solution Spray Tip may be partially clogged. See Clear Spray Tip Clog, page 21. Reversible Spray Tip is in UNCLOG position. Rotate arrow-shaped handle on Spray Tip so it points forward to SPRAY position. See page 21. Debris in paint causing obstruction. Strain the paint. See Clear Spray Tip Clog, page 21. Pressure is set too low. Align pressure control knob setting indicator to desired spray setting.
Troubleshooting Problem Cause Solution Spray gun stopped spraying while trigger is pulled. Spray Tip is clogged. See Clear Spray Tip Clog, page 21 Sprayer lost prime. Reprime sprayer. See Fill Pump (Prime Pump), page 16. When paint is sprayed, it runs down the wall or sags. Material is going on too thick. See Troubleshooting, page 36. Move gun faster. Choose a Spray Tip with smaller hole size. Choose Spray Tip with wider fan. Make sure gun is far enough from surface.
