If the displacement pump operates but the output is low on the upstroke, it could be that the piston ball is not seating properly. Another possibility is that the piston packings are worn or damaged.
Why isn't the distance adding properly on my Graco LineLazer V 250DC?
If the distance isn't adding properly, and MEASURE mode is inaccurate, the machine may not be calibrated correctly. Perform the calibration procedure. Also, ensure the rear tire pressure is properly adjusted to 55 +/- 5 psi (380 +/- 34 kPa). Check for missing or damaged gear teeth on the right side (when standing on the platform) and replace the distance gear/wheel hub if needed. Finally, inspect the distance sensor for looseness or damage, and reconnect or replace it as necessary.
What causes excessive paint leakage into the throat packing nut of my Graco LineLazer V 250DC?
Excessive paint leakage into the throat packing nut can occur if the throat packing nut is loose. Remove the throat packing nut spacer and tighten the nut just enough to stop the leakage. Another cause could be worn or damaged throat packings. In some cases, the displacement rod may be worn or damaged.
Why does my Graco LineLazer V 250DC Construction Equipment sprayer overheat?
Your sprayer may be overheating due to paint buildup on the hydraulic components, which requires cleaning. Another potential cause is a low hydraulic oil level; if so, fill it with hydraulic oil.
Why is the gun triggering slowly on my Graco LineLazer V 250DC?
Slow gun triggering can occur if the gun cable is pinched or kinked; try changing the gun cable routing or replacing the cable. Also, ensure that the system pressure is at least 1000 psi.
