  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.

  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 engine operates, but the displacement pump doesn't?

  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.
