Why is paint leaking out of the cup threads of my Graco 26D283 Paint Sprayer?

  If paint leaks out of the cup threads on your Graco Paint Sprayer, it may be because the cup is not properly seated. Verify the Cup Lid is tight and add Seal Lube (included) to the Cup Lid gasket to ensure an airtight seal. Also, make certain there is only one FlexLiner in the Cup Support and that there is no damage to or debris on the top sealing edge of the FlexLiner or Cup Lid gasket. Make certain the Cup Lid is properly threaded to the Cup Support, ensuring there are no threads visible when tight. Avoid flexing or pushing down on the Cup Support or pulling down on the FlexLiner when you evacuate the air out of the FlexLiner. If the issue persists, replace the FlexLiner.

Why does the spray pattern “spit” at the end or beginning when using my Graco 26D283?
- L
  Laura GuerreroAug 22, 2025
  If the Graco Paint Sprayer's spray pattern “spits” at the end or beginning, it could be due to excess material accumulated on the Spray Tip and Spray Tip Guard, or the Spray Tip is partially plugged. Clean the Spray Tip and Spray Tip Guard and clear the Spray Tip. If the issue continues, consider replacing the spray tip or the pump if it has reached its maximum life.

  If the pump filter is plugged in your Graco Paint Sprayer, remove the Pump Filter from the pump and clean both sides of it. While the Pump Filter is removed, inspect and ensure no dried paint debris is collected inside the pump inlet.

  If the Graco Paint Sprayer makes no sound when you pull the trigger, there are a few potential causes: * First, ensure the sprayer is correctly plugged into a grounded and functional power source. * If the motor has overheated, wait 20-30 minutes for it to cool down. * Lastly, an electronic control failure may require you to replace the electronic control.

Why is the spray pattern pulsating on my Graco Paint Sprayer?
- G
  gregg44Aug 31, 2025
  If the Graco Paint Sprayer's spray pattern is pulsating, it could be due to several reasons: * If you are moving too fast while spraying, try slowing down your speed of movement. * The spray tip may be clogged. * If the material is difficult to atomize, and your model has Speed Control, increase the speed until you achieve the desired pattern. * If the sprayer is too far from the target surface, hold it farther away from the surface. * Consider installing a different size spray tip.

What to do if my Graco 26D283 is not primed?
- I
  Isabella MillerNov 15, 2025
  If the Graco Paint Sprayer is not primed, it could be due to a few reasons. First, repeat the Start Up procedure to ensure all air is evacuated from the FlexLiner. An under tightened Cup Lid will allow air to seep into the FlexLiner and cause a loss of prime, so verify the Cup Lid is tight and add Seal Lube (included) to the Cup Lid gasket to ensure an airtight seal. If the sprayer sprays when upside down but not upright, there is likely still an air leak into the cup, so try replacing the FlexLiner and VacuValve (extra of both are included with the sprayer). Also, make certain there is only one FlexLiner in the Cup Support. Check that there is no damage to or debris on the top sealing edge of the FlexLiner or Cup Lid gasket. Make certain all the air is out of the FlexLiner and the VacuVal...
