4. Priming the Sprayer:
   • Turn the prime valve to the "Prime" position.
   • Place the drain line into a waste bucket.

   • Maintain a consistent distance (approximately 10-12 inches) from the surface.
   • Move the spray gun in smooth, even passes, overlapping each pass by about 50%.
   • Release the trigger at the end of each pass to avoid excessive material buildup.

Proper maintenance ensures the longevity and performance of your sprayer.

1. Cleaning After Each Use:

   • Clean the spray tip and guard separately.
