You did not mention what you would be using (material wise) but I assume it must be oil/Alkyd base for that use a .411 or .413 thin material about 15% and make sure you strain the paint first.Perry

What about the water pump and filter ? Perry

I worked at a tool rental center when I was going to college and learned many useful tips / tricks about airless sprayers. Airless sprayers have two check valves/balls that can stick on their seats or stay open due to chips of paint on seat. Easy method to prime is to remove intake filter from machine, tilt the machine back far enough so that the pick-up tube is pointing up high enough to pour water in tube until full; hold in this position and turn on machine. If water is sucked in turn off machine and tilt machine into pail of water and restart to check for prime. If it still will not prime remove water from pickup tube and use air pressure into tube with bypass valve open. Air pressure will attempt to release the stuck lower check ball. If air pressure does not release stuck ball you may have to use physical pressure against ball. If lower check ball was stuck you can assume that the upper check ball is probably stuck also. An aid to loosen stickey valves is to pour solvent into pickup tube with machine tilted back as before leave overnite. Enjoy

Just had the same problem with the same exact unit. Here's how to fix. Turn the pressure knob fully counterclockwise. Take a 5/8's wrench and back out the pressure knob 2 full turns. Yes, the exact same knob you just reversed only get a wrench on where it connects to the unit. Run it for a minute like that. On off a couple times.Run the gun and get the air out. You should notice it working. This is per the owners manual. Good luck man.
