What happens here

With the gun disassembled, the old needle can now be removed. Attempt to push the needle out by hand. If it is stuck due to dried paint or wear, carefully use a piece of wood and a hammer to gently tap the needle out of the housing. Be very careful not to scratch the needle if you intend to reuse it, as scratches can cause leaks. The presenter suggests using a wooden paint stir stick for this. Once the needle is out, inspect it and the small rubber O-ring attached to it. The O-ring should be replaced, and the needle can either be cleaned or replaced if damaged. A new needle and housing part typically costs around $55.

Goal: Remove the old needle and inspect components for wear

sides. And great sells a needle, the replaceable needle, and sometimes that that needle should just push right out. If it doesn't push out your finger, then you're going to have to knock it out. If um if you're not replacing the needle with a brand new one, if you hit it with something, it could scratch that needle. So, be really careful. I usually use a piece of wood. I just took a stir stick right here, took a hammer, just knock the piece off, the stir. Just like that. Now, I can use that little piece of wood to just cap that little needle out. It gets stuck in there sometimes and so you want to drop it free with hammer or a piece of wood. Piece of wood will scar the needle. We just set it on this box. Now we just knock that needle and there's your housing inside the gun. And there's a little another rubber O-ring on there. You can replace that O-ring if if the gun's not leaking and you just want to service it. You can replace the O-rings. take a look at it, clean this, and put it back in. Um, sure sells this
