What to do if Graco Paint Sprayer pump cycles but paint only dribbles?
If your Graco Paint Sprayer pump cycles, but the paint only dribbles or spurts: * Increase the pressure by slowly turning the Pressure Control Knob clockwise. * Unclog the spray tip. * Replace spray tip if it is too large or worn.
Why Graco Paint Sprayer pressure is set at maximum but cannot achieve a good spray pattern?
If your Graco Paint Sprayer can't achieve a good spray pattern even at maximum pressure: * Ensure the reversible spray tip is in the SPRAY position. * Select a smaller spray tip. * Replace the spray tip if it's worn. * Clean or replace the spray gun fluid filter. * Clean debris off the inlet screen. * Thin the material. * Remove the section of hose, if an extra section is added.
What to do if the Graco Paint Sprayer engine runs but the displacement pump doesn't?
If your Graco Paint Sprayer's engine is running, but the displacement pump isn't working, consider these potential causes and solutions: * The flow control might be set incorrectly. Set it to PRIME mode. * The air supply to the air control or gun might not be connected. Check and tighten the connections. * The air compressor might not be on. Start the compressor. * The engine RPM might be too low. Increase the engine speed. * There could be an air leak at the pump foot valve or siphon tube elbow. Ensure the foot valve is tight and the seal in the elbow is in place and undamaged. * The tip might be clogged. Clean the tip. * There might be insufficient compressor air. Increase SCFM or compressor size; the system needs at least 30 psi to operate. * The displacement pump rod m...
How to troubleshoot no pressure regulation on Graco Controller?
If there is no pressure regulation on your Graco Controller, it might be due to a damaged or clogged air regulator or line, no flow or pressure to the inlet of the regulator, or a damaged diaphragm. Clear any obstruction in the line, service the regulator if necessary, clear any obstruction in the fluid line to the regulator, or replace the diaphragm.
What to do if the pump is difficult to prime on my Graco Construction Equipment?
If the pump on your Graco Construction Equipment is difficult to prime, consider the following: * There might be air in the pump or hose: Check and tighten all fluid connections. Reduce engine speed and cycle the pump as slowly as possible during priming. * The intake valve might be leaking: Clean the intake valve, ensuring the ball seat is not nicked or worn and that the ball seats well. Reassemble the valve. * The paint might be too thick: Thin the paint according to the supplier’s recommendations. * Engine speed is too high: Decrease throttle setting before priming pump.
Why does my Graco A Series Water Pump fail to operate?
If the Graco Water Pump fails to operate, several issues could be the cause. First, check for any restrictions in the line or an inadequate air supply, and clear any obstructions while increasing the air supply. Second, ensure that the air pressure is sufficient and that air valves are open and clean, using an air filter. Next, check the fluid supply and refill if exhausted, purging air from the pump and fluid lines. A damaged air motor could also be the culprit, requiring servicing. Lastly, dried fluid might have seized the displacement rod; clean it, inspect or replace the throat packings, and remember to always stop the pump at the bottom of the stroke, keeping the wet-cup filled with compatible solvent.
Why is my Graco Paint Sprayer gun not fully actuating?
If the Graco Paint Sprayer gun does not fully actuate when triggered, the safety lock may be engaged, the muffler may be plugged, or the air valve o-rings may be damaged. Disengage the safety lock. Clean the muffler. Replace the damaged air valve o-rings.
What to do if my Graco Water Pump operates, but the output is low?
If your Graco Water Pump operates but the output is low, this could be because the fluid is too heavy for pump priming. Use the drain/purge valve and consider using a ram. Alternatively, the intake valve or seals may be held open or worn. Clear the valve and replace the seals to resolve this issue.
