SOURCE: Wagoner Procoat Airless Sprayer without

One cause for this is that one or both of the check balls in the piston are frozen in place. This can be caused by drying paint on the check balls or seats or, as is the case many times in our area, if you did clean the machine well with water without any airless conditioner in it, sometimes the water dries and leave behind minerals that 'lock' the check balls in the seats. Set the machine up in water and turn it on to prime. Using a hammer hit the pump head where the piston is working fairly hard. You are trying not to break anything but knock the check balls loose. If they come loose and water starts cycling through the system, let run a while to wash anything out before switching to paint. If this doesn't work, you may have to take the head apart to see why the check balls won't free up. It could be because of peices of dried paint that won't come loose by themselves.

Remove and Install prime/spray valve Wagner paint crew airless paint sprayer?


Was the unit purchased new or used? The price of a new is about $125-170. This unit is for homeowner occasional use, not for large jobs.Was the unit working on the previous use? If so were the cleaning instructions followed and not shortcut. If paint is failed to be totally removed on cleanup it will dry inside unit.There are very few replacement parts for this unit. If the unit is not working take wrench and try to remove prime/spray valve. You will have to remove knob to access this part.

My procoat won't prime


The inlet valve is probably stuck. It is a flat poppet type, so you need to free it up. A Graco dealer should be able to supply a special small plastic bottle with a special top filled with their Pump Armour to do this job. Otherwise you can unscrew the inlet valve from the cup side to clean it out, but be careful not to lose the small spring. You should always flush Pump Armour through the ProCoat after use otherwise the passageways corrode

Won't prime


Try to trouble shoot the problem by doing this:
clogged filter(s)
you did not clean paint out of machine properly on last use
the packings are worn and need to be replaced- it wont hold or build pressure- also that sprayer has a max tip size of .15

Will not prime


Most of the time when a unit will not prime it is because of a stuck inlet ball, I would put the intake in water turn the machine on to bleed. Then tap the machine where the paint comes in. 90% of the time this will get it going. Sometime you can stick a screw driver into the inlet ball and free it up. If this doe not work you need to take the machine apart and cleanor you have worn out packing.

Shoots drips


Most airless spray guns spit a bit when you pull or release the trigger because the paint between the spray tip and the paint valve is under pressure but not enough to atomise the paint. If you increase the pressure you may reduce the spit to a point when you don't notice it. A blocked filter could slow the paint getting through to the tip cause lower pressure.

How to remove the Prime/Spray assembly on the Wagner Paint Crew. The Prime/Spray knob is held on by a retaining clip which I can't figure out how to remove without resorting a hammer and pry bar and risk...


You can unscrew it without removing the plastic part - just use thin vice grips and get a piece of the metal nut, unscrew down (counter clockwise) and it should come off with average pressure. I checked mine, not much to go wrong there, then screwed back in. I have similar problem with pressure, it is likely a worn O ring. Seems to be in the outlet valve as I replaced some of the inlet valve rings and same effect. Research says the outlet valve is the problem if paint comes out of the squeezed nozzel while in Prime mode, which mine does, and is likely not building the pressure as some paint is flowing back through the worn outlet parts.
