What happens here

To lubricate the internal components of the gun, hold the gun in an upright position. Squeeze the trigger to open the diffuser and spray 'WD-40' directly inside the opening. This allows the lubricant to reach the seat ball and other internal mechanisms. Maintaining lubrication here prevents paint from gumming up and causing the trigger to stick. Always release pressure from the gun and pump before storage, as storing under pressure is detrimental to the packings. Use a wire brush or a 5-in-1 tool to clean any paint buildup on the gun's parts before lubrication for best results.

Goal: Ensure smooth internal trigger function and prepare the gun for storage by releasing pressure

it keeps things functioning properly this gun right here we've got um same thing right here you can see we've got done spraying a lot of cabinets with this this gun and right here there's some paint built up on it needs to be cleaned i'm going to get a wire brush out but i'm going to squirt a little bit of wd-40 on that on the rods right here and once again one of the reasons why i have an upright position like this a little bit of pressure behind that somebody didn't release the pressure on the gun so it's always good to release you never want to store your guns with pressure or your pump with pressure underneath it it's bad for the packings going to release that trigger drop a little wd-40 down inside down on there on the rods once again the reason why i like how my gun's in an upright position like this is it allows that rod and even on contractor two guns there's i'm kind of like these slides and guides paint will get down there down inside there gum up and it causes the trigger not to function properly or the trigger to even stick and i've had it happen multiple times you know with graco guns once i started uh lubricating them in this fashion with wd-40 and allowing that wd-40 to work down on those guides or rods i never had paint um building up gumming up or sticking on there never had a trigger stick again again before i get ready to spray i'm going to take a little wire brush clean the end of that and um that'll clean off really nicely but if paint gets built up on them pretty heavily at the end from spraying cabinets i've been spraying cabinets all day long you'll put some wd-40 on there it's going to make it a lot easier to clean that's simply how i keep my guns running you know functioning properly once i started lubricating them you'll in this fashion once i've never had a gun ever stick before nothing like trying to thread on you know a gun extension or a thread on your housing having paint gummed up on there once again the wd-40 will keep the paint from sticking on there it makes it clean off a lot easier you're with a five and one tool or a wire brush so lubricate your guns lubricate your pumps and you're going to have a better pa better experience spraying and not having your equipment break down on you so there you
