Check and Clear Bottom Fluid Section Ball
At 1:41 in
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.
