I need to know what the cleanout is for and how to operate it on a Graco 695 paint sprayer

Unsure of your model of paint sprayer, however, mine used a 2/3 turpentine to 1/3 paint to spray without clogging. Some people unscrew the paint holder and replace it with a paint can which can hold more of the paint mixture. Hope this helps.

Make sure that the capacitor is discharged and there is no power to board. Un solder the cap on both ends from the board and replace with another known working capacitor of same capacity and voltage. The value on the replacement can be a little higher but in no circumstances should the capacity or voltage be lower than the original.

wow i have rebilt alot of them is this a grayco???

same thing happening

It will be on the frame, in a place where it is not likely to be splashed by material of damaged. If you are looking for parts, the part number of the sprayer is more important.

In all the paint sprayers I've worked on, I've only been able to repair a couple prime valves and they went totally bad a short time after that. They can be taken apart and cleaned up but in the long run you'll be much further ahead replacing it if it isn't holding pressure in your system.

It could be something as simple as you have the pressure turned down so low it won't appear to be working try to turn the pressure up and see what happens.
The worst thing could be you did not clean the sprayer out properly and now the paint has dried and the shaft is frozen to the packings and the other internal parts of the your sprayer.

Airless won't prime- I always start trouble shooting an Airless that won't build/hold pressure look at sump hose inlet filter (the hose that goes into the paint if its got paint debris on it clean off filter and pour the paint thru a strainer bag into a clean 5 gal bucket-also remove the filter housing on the spayer and clean and flush and replace filter and housing- the shaft or the metal sleave has two ball bearings called "check balls" that maybe stuck turn on sprayer and put a piece of wood on shaft and give it a few good taps this will knock the check balls loose if after all this fails then you need to have new packings put in becuase the old ones are worn this is pretty easy to see because the rod the compresses the paint will have signs of paint on it indicating that the packings are worn.. Note keep rod and other moving parts oiled ith graco throat seal and finally Graco sprayers with the X on them are there (Graco) home owner line of sprayers that sell at home depot they are rated for only a certain amount of Gal per year keep it in good condition and cleaned store with coro-check inside of the pump when you are done using it.....
