What happens here

With the handle and packings reassembled, now attach the front and back sections of the gun. First, apply WD-40 or a packing/gun lube to all internal parts for lubrication. Insert the needle into the gun body, ensuring the pin goes all the way through and aligns correctly. You may need to push the needle gently to align it with the pinhole. Reinstall the tiny nuts onto the pin using the 9/32 inch socket and crescent wrench, tightening them securely. Once again, squeeze the trigger to retract the needle. Keep it pulled down while screwing the front fluid section back onto the gun. Tighten it with the 5/8 inch box wrench. Next, pull the trigger again and screw the spring side back on. The handle itself has a small Allen wrench screw that can be tightened to adjust the handle's pivot, ensuring it's straight and comfortable.

Goal: Fully reassemble the paint gun and perform final adjustments.

pull back. It's good and tight. Now we're going to begin putting the fluid side section of the gun back on. Once again, extremely important that you pull the trigger on this gun. Make sure that needle goes back because if you screw it on without pulling the trigger down, you could score the needle and you could end up making the gun leak. And so I've got my handle that goes on here. I stick your handle on first. and begin screwing that back together. Keep that trigger pulled down the whole time. It's been about 3 years since we put tappings in this gun, but I took them out. I'm going to reassemble it, test it out to see if it functions without leaking. If it's got good trigger pull, and if it functions properly, I won't put new packings in it. But you can pull the gun apart if it's been quite a while since you packed it or if the gun leaks pretty bad and you disassemble it. You want to just put new packings in it. They're about $50. We get them from Shure Williams and you can put it back together. But I like to take clean the packings, put it back together, see if it leaks. If it still leaks, then I'll put new packings in it. But now I got the gun together. Going to squeeze the trigger. Tighten that in. Now I'm going to tighten the spring side in all the way down. so it's tight and then straighten out my gun. And the gun, the handle has a little Allen wrench screw. This handle will swivel back and forth. You can tighten up that Allen wrench to make sure the gun is good and straight. And now the gun's been cleaned, reassembled, ready for use. Hopefully it doesn't leak. If it leaks, we'll replace the packings.
