Turn the prime valve to spray
With the gun pointed into the paint bucket, pull the trigger then turn the on/off switch to On
Increase pressure while continuing to pull the gun trigger
When paint flow ends and you see flushing fluid appear, turn on/off switch to off and release the trigger

If you’ve flushed your sprayer with water, flush it again with mineral spirits or Pump Armor to leave a protective coating which prevents freezing and corrosion
Wipe your Electric Sprayer hose and gun with a rag soaked in water or mineral spirits
Properly cleaning your sprayer and storing it in a safe, dry place will ensure your Graco sprayer ready for your next job.
