  If the gas engine of your Graco Construction Equipment pulls hard and won’t start, it could be due to hydraulic pressure being too high. Turn the hydraulic pressure knob counterclockwise to the lowest setting.

What to do if my Graco LineLazer V 200HS engine operates, but the displacement pump doesn't?

  Nathan LucasAug 25, 2025
  If your Graco Construction Equipment engine runs but the displacement pump doesn't, there are several potential causes. First, check if the pump valve is OFF and turn it ON. Ensure the pressure setting isn't too low by turning the pressure adjusting knob clockwise to increase pressure. Inspect the fluid filter for dirt and clean it if necessary. Also, check the tip or tip filter for clogs and clean them. If the displacement pump piston rod is stuck due to dried paint, repair the pump. Replace a worn, broken, or off pulley belt. If the hydraulic fluid is too low, shut off the sprayer and add hydraulic fluid. Lastly, if the hydraulic motor isn't shifting, set the pump valve OFF, turn the pressure down, turn the engine OFF, and pry the rod up or down until the hydraulic motor shifts.

What to do if my Graco LineLazer V 200HS displacement pump operates, but output is low on downstroke and/or on both strokes?

  If the displacement pump operates, but the output is low on the downstroke or both strokes, consider these possible causes: the strainer may be clogged (clean it), the O-ring in the pump may be worn or damaged (replace it), the intake valve ball may be packed with material or not seating properly (clean the intake valve), the engine speed may be too low (increase the throttle setting), there may be a suction tube air leak (tighten the suction tube), the pressure setting may be too low (increase pressure), the fluid filter, tip filter, or tip may be clogged or dirty (clean the filter), or there may be a large pressure drop in the hose with heavy materials (use a larger diameter hose and/or reduce the overall length of the hose).

What to do if my Graco LineLazer V 200HS is spitting fluid from gun?

  If fluid is spitting from the gun of your Graco Construction Equipment, it could be due to air in the pump or hose. Check and tighten all fluid connections and reprime the pump. Another cause could be a partially clogged tip, so clear the tip. Also, check if the fluid supply is low or empty, and if so, refill the fluid supply and prime the pump. Make sure to check the fluid supply often to prevent running the pump dry.

What to do if my Graco LineLazer V 200HS pump is difficult to prime?
- R
  Robert AndrewsAug 27, 2025
  If you're finding it difficult to prime the pump on your Graco Construction Equipment, several factors could be at play. First, check for air in the pump or hose by inspecting and tightening all fluid connections. Reduce engine speed and cycle the pump as slowly as possible during priming. Another potential issue is a leaking intake valve; clean the intake valve, ensuring the ball seat is free from nicks or wear and seats well. If the pump packings are worn, they should be replaced. The paint might be too thick, in which case, thin it according to the supplier’s recommendations. Finally, ensure the engine speed isn't too high by decreasing the throttle setting before priming the pump.

What to do if my Graco LineLazer V 200HS Construction Equipment spray icon is always shown on display?
- S
  Sara VanceSep 15, 2025
  If the spray icon is always shown on the display of your Graco Construction Equipment, the interrupter may be improperly positioned. Turn the screw clockwise until the spray icon is synchronized with the fluid spray. Alternatively, the reed switch assembly may be damaged and need replacement.

Why is there excessive hydraulic pump noise in my Graco Construction Equipment?

Why is there excessive paint leakage into the throat packing nut of my Graco Construction Equipment?
- S
  sharplouisSep 2, 2025
  Excessive paint leakage into the throat packing nut of your Graco Construction Equipment can occur if the throat packing nut is loose. Remove the throat packing nut spacer and tighten the throat packing nut just enough to stop the leakage. It could also be caused by worn or damaged throat packings.
