Troubleshooting for Magnum Sprayers

Why won’t my sprayer prime or draw paint up from the paint bucket?

Follow these steps:

  • Make sure the suction tube (the larger, braided tube) and the strainer are completely submerged in the paint.
  • Some paints are very thick and require the pump to slow down to prime. Turn the on/off switch ON and then OFF until the pump is about to stops and then turn the sprayer ON and then OFF again. You may need to do this a few times until paint works its way into the pump and out the drain tube (smaller clear tube).
  • Remove the suction tube (larger, braided tube). Insert the pointed end of a pencil into the inlet and push up to free the inlet valve ball.
  • Remove and clean the outlet valve. (See component identification and troubleshooting in your owner’s manual.)
  • Remove and clean the inlet valve. (See component identification and troubleshooting in your owner’s manual.) Be sure not to lose the inlet ball (some models have a spring as well).
  • Remove the strainer and connect the Power Flush adapter and a garden hose to the suction tube. Following the directions in your owner’s manual, flush the sprayer with water for one minute. Reinstall the strainer on the suction tube, submerge the suction tube in the paint and prime the sprayer.

My sprayer is on, but nothing happens.

Make sure the unit is plugged into a working outlet. If it is, turn the sprayer on and then turn the sprayer’s pressure control knob clockwise until the motor starts running.

Why does my sprayer’s motor keep turning on and off?

When the gun trigger is released, the motor and pump will automatically turn off. Once you pull the gun trigger and start spraying, the motor and pump will turn on again. This is normal operation and eliminates constant motor noise and reduces wear for longer life.

If the motor continues to run when the gun trigger is released, it is not primed.

Why doesn’t paint come out of the spray gun when I pull the trigger?

Make sure the Prime/Spray Valve is pointed forward in the Spray position

The spray tip is likely clogged. Turn the spray tip 180 degrees to the unclog position, aim the spray gun into a bucket and pull the trigger for one second to clear the clog. Turn the spray tip back to the spray position and resume spraying.

How do I get rid of the tip clogging?

The best way to reduce tip clogs is to strain you paint of the larger debris.

How do I get rid of the lines on the top and bottom of my spray pattern?

Make sure the pressure control is turned up to a higher spray pressure. Try moving closer to the surface. If you continue to see lines in your pattern, you may need a larger tip size if you sprayer can support it (the largest tip that the Project Painter Plus and X5/LTS15 can support is the tip that is included). Otherwise, add a small amount of water of solvent, depending upon your material. Be sure to work the water or solvent into the paint that is in your paint hose by reversing the tip and spraying the paint back into the paint bucket until the thinner material is worked into the paint hose. Don’t forget to turn your spray tip back to the spray position.

My spray fan is not solid or has gaps in it so the finish is not even.

You most likely have a tip plug. Turn the spray tip 180 degrees to the unclog position, aim the spray gun into a bucket and pull the trigger for one second to clear the clog. Turn the spray tip back to the spray position and resume spraying.

Why is there paint leaking from the bottom of the sprayer?

The pump needs to be serviced or replaced.

Why is there fluid leaking from where the spray hose attaches to the pump or spray gun?

The spray hose connection is not tight. Use a wrench to tighten the spray hose to the sprayer and to the gun.

Troubleshooting for TrueCoat 360 Sprayers

How do I stop air from leaking back into my sprayer cup?

Make sure the cup lid is tightened securely and VacuValve lid is closed. Make sure the cup assembly is securely attached to the sprayer. Try squeezing all of the air out of the cup and priming.

Remove black o-ring on the pump inlet and clean/lubricate it.

How do I reduce the amount of paint coming out of my sprayer?

If your sprayer has a dual speed or variable speed control, turn the speed down to low. Try using the smaller, grey tip to reduce the amount of material flowing out of the gun.

Why did my sprayer stop spraying?

You most likely have a tip clog. To clear the clog, twist the handle 180 degrees and pull the trigger into a waste area. Twist the handle back to the spray position.

How do I get rid of the tip clogging?

The best way to reduce tip clogs is to strain you paint of the larger debris.

My sprayer has been spraying fine for several quarts and now the motor won't run.

The thermal overload has tripped. It will reset on its own. Let the sprayer cool down for 20-30 minutes and try it again.

How do I get rid of the lines/stripes in my spray pattern/finish?

You are moving too fast. Try slowing down your arm movement. If you have a sprayer with speed control, switch to High or increase the speed setting to the highest setting.

How do I get rid of the lines on the top and bottom of my spray pattern?

Try moving closer to the surface and slower. If you continue to see lines in your pattern, add a small amount of water of solvent, depending upon your material, reprime and spray.

My sprayer sprays water but not paint?

Debris is caught in the sprayer. Try reversing the spray tip 180 degrees to see is paint can be sprayed. If it can, turn the spray tip back to the spray position to spray. Turn the sprayer upside down with the cup and strainer removed. Pour hot water into the inlet of the sprayer if you sprayed water based materials on last project, or mineral spirits if you sprayed oil-based materials on the last project. Let sit for 5 minutes and then remove the spray tip and spray the material out the front of the sprayer (make sure your Prime/Spray Valve is at Spray). If these steps do not resolve the problem, contact Graco Technical Support at 1-888-541-9788.

My sprayer worked great the last time I used it. Now it won't spray anything at all.

The most common reason for your sprayer to not work on next use is that the front guard has been removed from the sprayer during cleaning. Removing the guard will cause damage or missing parts when it is reassembled. Please call Graco Technical Support for help replacing the part at 1-888-541-9788.

The motor runs but my sprayer won't spray.

Turn it upside down, if it sprays then there is still air in the cup. Purge the air through the VacuValve cap.

Check the spray tip to insure it is properly installed and pushed all the way into the housing.

FAQs for Magnum Sprayers

What type of material can be used with Magnum sprayers?

All Magnum sprayers can spray water-based and solvent-based paints, stains and primers that can be cleaned with mineral spirits. Materials that cannot be used with Magnum sprayers include solvent-based lacquers (exceptions are the ProX21 and the Pro210ES), texture based materials and elastomeric.

All sprayers include a 515 spray tip that sprays a 10 inch spray fan for spraying latex paint on larger surfaces. When spraying stain, we recommend you use a spray tip that restricts the amount of paint coming out of the front, such as a 311 or 413 spray tip. The first number of any spray tip is multiplied by 2 to give you the width of the spray fan. A 311 tip will spray a 6 inch spray fan and the 413 wills spray an 8 inch spray fan. The second 2 numbers indicate the hole size. The thicker the material, the larger the hole size should be to get the best spray finish.

Check the paint manufacturer's recommendation in the "Application" section of the label on the bucket or can of paint.

No, only the Graco Pro210ES and larger Graco sprayers need TSL. Magnum sprayers only need to be stored with Pump Armor after every use to assure reliable priming on your next project.

Once the fan pattern starts to get smaller, the spray tip should be replaced. The same amount of material is coming out but not covering as large of an area on your wall. You will need more paint to finish the project with a worn spray tip.

It is best to spray at the lowest pressure that provides a good spray pattern in order to reduce overspray. Start at low spray and spray on a piece of cardboard. If you see lines on the top or bottom of the spray pattern, increase the spray pressure until the lines go away.

The most important maintenance with any airless sprayer is to thoroughly clean the sprayer and store the sprayer with Pump Armor between use. Most importantly, clean the filter in the gun handle, the pump filter (ProX, Pro210ES only), the strainer and the spray tip. With good cleaning and using Pump Armor, your sprayer will last for years.

We recommend a 12-gauge extension cord no longer than 100 feet.

FAQs for TrueCoat 360 Sprayers

What type of material can be used with TrueCoat 360 sprayers?

All TrueCoat 360 sprayers can spray water-based and solvent-based paints, stains and primers that can be cleaned with mineral spirits. Materials that cannot be used with TrueCoat 360 sprayers include any flammable materials, texture based material, and elastomeric.

No. Once you squeeze all of the air out of the bag, you close the VacuValve cap to seal out the air. We recommend you squeeze out the air again once you prime the sprayer. After that, there is no need to squeeze the bag while spraying.

Yes, you need to evacuate the air out of the cup and prime after each cup fill.

Yes. The FlexLiner bag is made of a durable, pliable plastic that is very easy to rinse out and reuse.

No. All TrueCoat 360 sprayers include two spray tips for spraying small or large surfaces. They are both .015 inch orifice size tips. The black spray tip sprays a 12 inch pattern, the gray spray tip sprays a 4 inch pattern. No other tips or sizes are needed or available.
