Why does clutch squeak each time it engages in my Graco Paint Sprayer?
If the clutch squeaks each time it engages in your Graco paint sprayer, it's likely because the clutch surfaces are new and not yet matched to each other, which can cause noise. The noise should dissipate after a day of run time as the surfaces wear into each other.
Why is the distance not adding properly on my Graco LineLazer v 5900?
If the distance is not adding properly on your Graco paint sprayer (measure mode will be inaccurate and speed will be wrong), the machine might not be calibrated, so perform the calibration procedure. The rear tire pressure might be too low or too high, so adjust the tire pressure to 55 +/- 5 psi (380 +/- 34kPa). Gear teeth might be missing or damaged (right side when standing on the platform), so replace the distance gear/wheel hub. The distance sensor might be loose or broken, so reconnect or replace the sensor.

Your Graco Paint Sprayer engine may not start due to several reasons: the engine switch might be OFF, so turn it ON. The engine could be out of gas, so refill the gas tank. The engine oil level might be low, so replenish oil if necessary. The spark plug cable might be disconnected or damaged, so connect or replace the spark plug. If it's a cold engine, use the choke. The fuel shutoff lever might be OFF, so move it to the ON position. Oil might be seeping into the combustion chamber, so remove the spark plug, pull the starter 3 to 4 times, clean or replace the spark plug, and start the engine, keeping the sprayer upright to avoid oil seepage.
