Does a Wagner Paint Crew sprayer take lubricant?

The Wagner Paint Crew airless sprayer does not require oil for its operation like full professional sprayers. The piston is off-set from the pump chamber with the inlet and outlet valves opposite each other, however you need to protect the parts from corrosion between use and Wagner recommend running some light oil through it after cleaning. If you will be using it in a day or so for water based paint, you could run a 10% solution of their EasyGlide through it.

Unit won't prime,

YOU HAVE A STUCK INLET BALL
Have the unit in water, pressure relief valve turn the machine on and tap with a hammer at the inlet ball, This frees it up 90 of the time.
Otherwise the machine need to be disassemble

My titan 330 airless paint spray will not shut off while primming

Airless paint sprayers should not turn off while in prime mode. As long as the prime valve is open the motor can pump paint but the system will not build any pressure. Once the prime valve is closed the pump should pump paint into the hose until it gets to the pressure level required to turn the motor off. If the pump does not turn off with the prime valve closed, it could be that the spring in the valve is weak and won't hold the valve closed under pressure. If the hose is up to pressure and the motor just keeps trying to pump paint, you may have a bad pressure sensor or it is disconnected from the circuit board.

hello ald... use a fine piece of wire and clean the opening that the paint comes out through. It has a tendency to fill in as you spray. Joe

Did you make sure the paint container is properly sealed and not letting pressure to release? You may need to remove top and clean rim of container and top.

Wagner Paint crew - No pressure

In order of likelyhood:

1. There is an inlet valve where the paint first enters from the hopper. With the machine off, you can poke your finger all the way down the hole. It's spring loaded and will depress abouta quarter inch. If the inlet valve is stuck no paint will pump in PRIME or SPRAY position.
2. In SPRAY position. Motor runs for a few seconds then turns off. This means the pump is working. When you pull the trigger, if you get poor pressure, the problem is in the gun. Unscrew the handle and remove the filter. Clean out everything you can, and replace filter if necessary. Also try turning the spray nozzle 180 degrees and spray to clear if necessary.

there are more things that can go wrong, but these are the most likely.

The pump "stuck"

I think you do know that you did not properly flush and clean the pump after the last
time you used it......If it is a diaphragm pump, remove the inlet valve and make sure
the valve and spring are perfectly clean....Soak it in paint remover for a day or so
if needed.....Remove the retaining nut which is covering the outlet valve......Clean the
very, very small ball and spring....DO NOT LOSE....Replace all parts when clean....
Also check your hydraulic fluid in the pump's sump.......If it is a piston pump, remove
the inlet valve and make sure the ball is free and not stuck to its seat.....Tilt the pump
on its back and look up into it.....With a pencil see if the other small ball in the piston
is also free....Try to pump warm water through the cleaned pump....Without hose or gun......If it pumps fluid, replace hose and gun without spray tip....Test for flow again.
Then finally replace the spray tip......Chase out the water with the paint.....

1. Does it pump paint in PRIME position. If yes, then the outlet valve assembly may be stuck or bad.

2. If it won't pump paint in the PRIME position, the inlet valve may be stuck, just poke your finger down the inlet hole (machine off) . It is spring loaded and should move about an 1/8".

3. The worst option is the pump piston if froze. To check: remove the plastic hopper assembly, comes off with about 4 screws from underneath. The whole thing just pulls off. Now you can see the inlet assembly with two O rings. Use the white plastic hex shaped tool comes with the spray, and stuck on the lower base of the unit. Unscrew the inlet assembly. If clean enough, you can see the end of the piston. It's about a 1/4" diameter. Turn the machine on for a moment and you shoud see the piston move back on forth. If it doesn't the piston is froze. Good Luck with that.

Thanks for your post, I found that my piston was frozen, what a pain, I took the pump face off of the motor slid the plastic pivot/ spring off,used a screwdriver and a hammer to force the piston back little by little from the top again also using a half a can of WD40 and then took the back of a hammer and placed the fork under the piston rear slot and tapped w/ another hammer... it finally backed out, of course I was covered w/ WD40- I then took the piston to my grinder and polished the hell out of it / and also put pieces of a rag and wrapped around the end of a long reversed srewdriver bit in a drill and polished the inside of the brass sleeve for the piston. after re-assembly, the unit ran like a champ.-whew!
David Donna Guzman Sep 19, 2012

thanks for your post. I did notice when I removed the hose from the outlet valve, when I had it on prime it would shoot water through the hose and also from the outlet valve. I did notice that the piston was moving back and forth. For me it seems like I need to buy and outlet valve assembly.
