SOURCE: Sirs: I was painting, and everything was going

i will tell you what the first problem is...YOU BOUGHT A WAGNER!
i know they are priced for the homeowner and marketed as such, but they are horribly built!

but heres some things that may help...
did you check that the tip was compleately cleared?
the pinhole helfway down the shaft is likely clogged, you need a tiny pin or needle to clean it.

2nd did you leave paint in it after using it?
all sprayers are very fickle and should be completly cleared though with at least water until you see no colorization in the water.

its best to run 'pump juice' through it as well to keep the parts lubricated.

also there should be small yellow filters in the handle of the gun, which will be caked with paint once again if you didnt run lots of water through it.

i have to take my CAMBELL HAUSFELD into the shop about every 100 gallons sparyed through....fickle creatures.

SOURCE: 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.

I cannot find model 834
Check your owner's manual for troubleshooting steps
We used paint sprayers every day for years.
The prime valve goes bad
The steel balls that direct the paint between prime and hose, wear out
The steel ball that holds prime and hose pressure wears out

The steel balls can also get stuck
Turn prime lever on
Take a hammer and tap/bang front of paint sprayer until ball comes loose
I cannot see your sprayer so I don't know where the ball is located
The photo below says, keep lever up >> in your case lever is down or in prime position while tapping

What cain of oil a cant uuse for wagner 1250 hp


Your Wagner 1250 is a diaphragm airless sprayer, which uses hydraulic oil to push the diaphragm, so the oil must be hydraulic quality as it gets quite hot; don't use any other type. The Wagner part number for their quart size is 0088009

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.

How can I fix a electrical spray gun that does not spray but makes noise like its going to spray.


R D, I think the spray nozzle is blocked with previous paint job. I would try soaking it in paint solvent for a few hours to see if it helps. Use the cleaning brush to clean as much as you can all the channels where you see paint. good luck.

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.....
