What to do if my Graco Magnum X7 Paint Sprayer pump does not prime?
If your Graco Paint Sprayer pump does not prime, make sure the Prime/Spray Valve is in the PRIME position (pointing down). Check the inlet screen for clogs and ensure the suction tube is immersed in fluid. If you haven't already, prime the pump with water or solvent-based flushing fluid. Also, make sure that the suction tube is not leaking, allowing air to enter, and replace it if cracked or damaged.
What to do if the Graco Magnum X7 Paint Sprayer pump cycles but doesn't build up pressure?
If the pump of your Graco Paint Sprayer cycles but does not build up pressure, ensure that the Prime/Spray valve is in the SPRAY position (pointing forward). Also, make sure the pump is primed. Check that the inlet screen isn't clogged and that the suction tube is fully immersed in the fluid. Additionally, inspect the suction tube for any cracks or cuts, ensuring the clamp is securely on the hose; replace the tube if it's damaged.
What to do if Graco Magnum X7 dribbles or spurts paint?
If your Graco Paint Sprayer pump cycles but the paint only dribbles or spurts when you trigger the spray gun, first, make sure the pressure isn't set too low by slowly turning the Pressure Control Knob clockwise to increase the pressure. Also, check if the spray tip, InstaClean™ fluid filter, or spray gun fluid filter are clogged and clean or replace them as necessary. Finally, the spray tip might be too large or worn, requiring replacement.
Why my Graco Paint Sprayer pump cycles but does not build up pressure?
If your Graco Paint Sprayer pump cycles but doesn't build up pressure, first, ensure the pump is properly primed. Check that the inlet screen isn't clogged and that the suction tube is fully immersed in the paint. Also, inspect the suction tube for any leaks and tighten the connection or replace the tube if necessary. If these steps don't resolve the issue, the Prime/Spray Valve may be worn or obstructed, requiring service at a Graco/MAGNUM authorized service center. Another potential cause is a stuck pump check ball; refer to the 'Pump does not prime' section for troubleshooting steps.
What to do if Graco Paint Sprayer gun stops spraying?
If your Graco Paint Sprayer gun stops spraying, turn the arrow-shaped handle to the unclog position, aim the gun into a waste pail, squeeze the trigger, then return the handle to the spray position.
Why Graco Magnum X7 Paint Sprayer pump cycles but pressure doesn't build up?
If the Graco Paint Sprayer pump cycles but pressure doesn't build, first, ensure the pump is properly primed. Check the inlet screen for any clogs and clean them off. Verify the suction tube is fully immersed in the paint. Refill the paint pail if it's empty and re-prime the sprayer. Inspect the suction tube for air leaks and tighten the connection or replace if cracked. If the pump check ball is stuck, refer to the 'Pump will not prime' section and press the pump priming button two times.
What to do if Graco Magnum X7 pump does not cycle?
If your Graco Paint Sprayer pump isn't cycling, even when plugged in and the power switch is on, start by checking the pressure control knob and turn it to increase pressure. Make sure the electrical outlet is providing power by testing it with another working device, and reset the circuit breaker if necessary. Inspect the extension cord and sprayer electrical cord for damage, replacing them if needed. If the paint is frozen or hardened, thaw the sprayer completely in a warm area before attempting to use it, or replace pump packings and remove residue from valves and passages.
What to do if my Graco Paint Sprayer power switch is on but the motor doesn't run?
If your Graco Paint Sprayer's power switch is on and the sprayer is plugged in, but the motor doesn't run, first ensure that the pressure isn't set to zero; turn the pressure control knob clockwise to increase the pressure setting. Then, check if the electric outlet is providing power by verifying that the lighted plug on the sprayer is lit; if not, reset the building circuit breaker or replace the fuse. A damaged extension cord or sprayer electric cord could also be the culprit, so inspect and replace them if necessary.
Why is paint leaking from my Graco Magnum X7 pump?
If paint leaks down the outside of the pump on your Graco Paint Sprayer, replace the pump packings.
