- RRobert MartinSep 7, 2025
If the pump output is low on the downstroke or on both strokes for your Graco Construction Equipment, check these: * The inlet screen may be clogged. Clean the screen. * The piston packings might be worn or damaged. Replace the packings. * An intake valve ball may not be seating properly. Clean the intake valve. * The engine speed could be too low. Increase the throttle setting. * The clutch might be worn or damaged. Replace the clutch.
