  If your Graco Construction Equipment engine or sprayer won’t start, first, ensure the engine switch is turned on. If it still doesn't start, check the gas tank and refill if empty. Also, verify the engine oil level and replenish if low. Make sure the spark plug cable is correctly connected and not damaged; reconnect or replace the spark plug if needed. Finally, if there is frozen water in the sprayer, allow it to thaw completely before attempting to start.

What to do if the fluid delivery is low on my Graco LineLazer 3000?
- S
  Steven TrujilloAug 23, 2025
  If the fluid delivery is low in your Graco Construction Equipment, start by cleaning the inlet screen. If the issue persists, increase the pressure setting. You may also need to increase the throttle setting to raise the engine speed. Check and clean the fluid filter, tip filter, or the tip if they are clogged or dirty. If there is a large pressure drop in the hose, consider using a larger diameter hose.

What to do if the pump output is low on my Graco LineLazer 3000 Construction Equipment?
- C
  Chase JacksonAug 25, 2025
  If the output of the pump is low on the downstroke or on both strokes in your Graco Construction Equipment, begin by cleaning the inlet screen. If the problem continues, replace the piston packings. Ensure the intake valve ball is seating properly; clean the intake valve if necessary. Also, check that the engine speed is not too low, and increase the throttle setting if needed. Lastly, inspect the clutch for wear or damage and replace it if necessary.

Why is the pump difficult to prime on my Graco LineLazer 3000?
- J
  Jade Curtis MDAug 27, 2025
  If the pump is difficult to prime on your Graco Construction Equipment, check and tighten all fluid connections to eliminate air in the pump or hose. Reduce the engine speed and cycle the pump slowly during priming. Clean the intake valve, ensuring the ball seat is in good condition. If the pump packings are worn, replace them. If the paint is too thick, thin it according to the supplier's recommendations. Finally, decrease the throttle setting if the engine speed is too high.

What to do if displacement pump doesn't operate on Graco LineLazer 3000?
- J
  John SchmidtAug 28, 2025
  If the engine operates but the displacement pump does not in your Graco Construction Equipment, first ensure the pressure control switch is turned on. Next, check if the pressure setting is too low and increase it by turning the pressure adjusting knob clockwise. Clean the fluid filter if it's dirty. Also, clean the tip or tip filter if clogged. If the displacement-pump rod is stuck due to dried paint, repair the pump. Replace the connecting rod or drive housing if they are worn or damaged. Check the wiring connections to ensure electrical power is energizing the field. If the clutch is worn, damaged, or incorrectly positioned, replace it. Finally, repair or replace the pinion assembly if it's worn or damaged.

What to do if fluid is spitting from the gun on my Graco LineLazer 3000?
- R
  riveraelizabethAug 29, 2025
  If you notice fluid spitting from the gun of your Graco Construction Equipment, first, check and tighten all fluid connections and reprime the pump to eliminate air. If spitting continues, clear the tip, as it may be partially clogged. Also, ensure that the fluid supply is not low or empty; refill it and prime the pump, checking the fluid supply frequently to prevent running the pump dry.
