Goodfast08, Congratulations on wanting to take the bull by the horns and just fix it yourself! Most people new to this just send it back, but since you have already determined the gun to be accurate you are smart to not risk it to the perils of shipping, or to get another that might not shoot as well. Eventually, all these guns need to be serviced anyway.
If you haven't already, just watch some videos of people taking apart airguns first. Hajimoto has some good ones where he talks through what he is doing and why. You will want to have the right tools handy along with silicone oil and silicone grease, and dry lubricant ( I use graphite) for the hammer. I always run my hammers dry and I don't get any weird velocity changes with the seasons. Opinions vary, that's mine. Do this in a very clean area, not on a garage workbench with lawn mower parts on it and dust blowing in. More like your kitchen table. Have a smooth plastic pipe that is longer than your airtube, to push regs in and out. I like the diameter to just fit inside the tube so that it doesn't push on the adjustment screw. This gun has a bleed screw so you won't have to do anything weird like unscrewing guages or burst disks to de-gas, which is a nice feature. Take your time and be careful, you rarely have to tighten anything very much with pcp's, the orings handle the pressure not the threads. In some cases you actually have to back things off so guages line up. I know that I never thought about stuff like that when I started, so I am just mentioning it. Others will now probably chime in on this to let you know all the variables. Good reading the first time. Good luck!
By the way, this really isn't a good gun to use a bipod with, Macavity screwed up with that, no denying it. You will be much better off using a shooting rest, or a bag, in the front, or shooting sticks if you need support. Bipods connected to the front plastic picatinny rail, flex it like crazy.
