Open Question

Spray gun won't go back together after cleaning.

After taking spray gun apart to clean, cannot figure out how to get it back together. there are no pictures that explain which part goes where. We are in the middle of our painting project and think we might have to discard this airless paint sprayer and do it by hand...UGH! Can anyone tell us how to reassemble the paint spray part?

How do you take this hvlp gun apart for proper cleaning of the spray gun?

I've found over the years the least amount of times you can tear a spray gun completely apart the better. Usually a real good 'flushing' with lacquer thinner will suffice. I will take the air cap off and let it soak in thinner to dislodge any build up but other than that, I simply run thinner thru till it runs clear out the tip.

I also 'back flush' which involves having thinner in the cup and the air supply hose attached. the air pressure should be adjusted quite a bit lower than what you use for spraying paint.

Then you place a clean shop towel or rag over the air cap of the gun and pull the trigger. This forces air back into the paint cup 'back flushing' the gun. Then take the rag away from the cap and pull the trigger again to run thinner thru the gun the normal way.

IF you still want to tear the gun apart for cleaning you can hopefully get some idea with this video link;

Make sure that the vents on the gun are clean and if the problem is still present then you have a problem with wear on the bushing or the needles. Air is blowing back into the cup before the needle is opening enough. So this could be a pressure, timing or wear issue.

My 2510 tracktor won't start

drain the fuel out, get rid of all the fuel additives. take the carburetor off and take apart and clean with spray carburetor cleaner. clean the bolt that goes in to the bottom real good. clean the holes in it good. put it back together and it will be good. it sounds like it has debris in there some where that needs cleaned out.

440i wont stop spraying

Either your gun is dirty and the valve spring can't close the tip valve properly or the seat it pushes against is damaged. First try cleaning the gun very throughly. Take it apart and get everything out of the gun that doesn't belong there. If it still does the same thing you can buy a repair kits for the paint guns but they're usually expensive and you're almost always better off replacing the gun.

I dropped the feed dogs and they won't come back up.

Ignore all the other comments, they are wrong.
The feed dogs are driven by the feed driver mechanism, turn the hand-wheel forward and the feed dogs will come up. (Providing you have the feed dog switch to the up position).
