Repair A Graco 695 Airless Paint Sprayer Not Priming Properly.

What happens here

With the fluid hose removed, tilt the sprayer back to look directly up into the bottom fluid section. You should see a small check ball. Inspect the area around the ball for any debris caught between the ball and the housing. If you see debris, use a small flathead screwdriver or needle-nose pliers to carefully pull it out. Be extremely careful not to scratch or damage the ball or its housing, as this can lead to further priming issues. Once cleared, ensure the ball can move freely up and down. A quick workaround for minor clogs, if you don't want to disassemble, is to tap the lower fluid section very lightly with a hammer while the sprayer is running and on prime mode. This might dislodge small debris.

Goal: Remove debris from the bottom check ball to restore proper priming.

and that hose will just come right off. If you have to just tap it with a hammer down here in the fus lightly just to get it to come down, then just use a hammer. Be careful not to damage that hose. I'm going to tilt my sprayer back. I'm just going to look up inside there. Got a ball that moves up and down. Allows the paint to either go up or not go up inside the fluid [music] section. There's any debris in there. Just going to use a little tiny flathead screwdriver just to pull it out. And a pair of needlenose pliers. Make sure you don't scratch that ball or you could end up causing a problem with paint not priming properly. So, just reach up there, grab the debris. Just going to re put our hose back on and then you're good to go. Another good trick is prior to actually having to take everything apart, you could actually use a hammer to try to tap on your lower fluid section. If you if it's just a little tiny little piece of debris or something, sometimes just the hammer and some taps [music] will make it pass through. So, with the sprayer running and it's on prime, you just tap this lower fluid section like this, just very lightly, and sometimes that'll free it up. And then just to put it back on, just going to put it back on. We're going to show you a closeup of what that all looks like. Here we're going to look down here at our lower fluid section. We're going to tilt our sprayer back here and just look up inside. You can actually see up inside there. There's a ball up inside there. Got our sprayer tipped over here. And up inside there, there's a ball. You just want to make sure there's nothing around that ball caught wedge between the ball and the outer housing.
