Fusion AP Spray Gun Cleaning | Chemline


– Hi, I’m Steve from Chemline, and as part of Chemline’s commitment to excellent customer service, I’m gonna show you how to clean your Fusion AP spray gun and parts. (hard rock music) You want to start out with
two buckets of solvent, MEK or acetone in them. You also need your
appropriate-size drill bits, which will come with your mix chamber, and a soft plastic or brass brush. You’ll also want white
lithium grease on hand for when the parts are clean and you’re ready to reassemble the gun. Few rules of thumb, you wanna be careful not to soak the parts in solvent
for long periods of time. It can start breaking down the o-rings, and they’ll need to be
replaced more often. Once you’ve disassembled your gun, put all of your A parts into the A bucket and all the B parts into the B bucket. Once you’ve disassembled the gun, take the fluid head and quickly
immerse that in solvent. Once you remove it from solvent, check each orifice in the head of the gun. We have two holes, one
on the A, one on the B. So actually where the filters go in. Sits there at about a 60-degree angle. We’ll want to make sure that
we’re free and clear there on each side. When we’re done with that, we’ll take our brush, and we’ll clean out the
filter housing itself where it fits in, rinse it with some clear solvent. We’ll set it aside to dry. Once dry, we’ll put a
little lube on our hands, and we’ll rub a thin layer on that part. When you use a brush to clean it, always make sure we’re using a soft plastic or a brass brush. The reason we don’t wanna
use a hardened steel brush is because they remove paint quickly. If we’re removing paint
from inside the orifi, the o-rings will not fit
accurately, and we’ll have a leak. We always want to use something
soft to clean out gun with. After we clean the head of our gun, we want to clean the filter
cartridge parts very well, including the cartridge
itself with MEK or acetone. After we do that, we’ll do the same to clean the side seal cartridge parts, and then we’ll be ready for reassembly. When we replace the mix chamber, we’ll also want to change side seals. Take the 60 mesh filter off. Put that into the B side. Remove the post and the ball
and the cartridge itself. Side seal and side seal cartridge. Good, and filter housing. (hard rock music) Clean MEK. (hard rock music) And you brush when needed. Remove any grease or any built-up poly. Filter cartridge itself. (hard rock music) We reassemble the filter
cartridge assembly. The ball goes in first, followed by the spring, and then the post. (hard rock music) Screw it back down. The post threads in, just has to be below flush. (hard rock music) It’s ready for reassembly and our side seal. (hard rock music) O-ring goes in first. (hard rock music) Side seal’s complete and
verified by it bouncing. (hard rock music) Now for the A side parts. While we’re cleaning our parts, removing things with clean solvent, you can use compressed air
while you use your brush. Air does a great job of knocking
things out of small orifi. Ready for reassembly. (hard rock music) Ball, spring, our post for our check valve for the A side. 60 mesh filter. (hard rock music) Side seal cartridge, side seal spring, and the actual side seal itself. A little lube on the o-ring. Place it. Verify. It’s good to go. Now take your air cap. Clean it off. (hard rock music) Whenever we replace the mix chamber, we also wanna change our side seals. You don’t have to replace
the whole cartridge, but you do have to replace
the side seal button itself. We do this because
there’s intimate contact between the side seal and the mix chamber. They’re machine parts,
so if one is wearing, the other is, too. Here, we can clean this real quick. (hard rock music) Solvent from front and back. (hard rock music) I’m gonna drill bit down it quickly and again verify we can see through it. We’re good to go. Just get a thin film of
white lithium as well. You can also put ultra-fine sandpaper and a cloth on a flat surface for a chamber that’s
scratched to resurface it. Most mixed chambers will last
approximately 20 drum sets. If you notice any scratches, you should replace it or refinish it. Over time, the orifice is going to expand just through erosion. It’s hardened steel, and it will wear out. They do not last forever. We.’re gonna through your mix ratio off if one orifi gets larger than the other. You should always check
that with your drill bit. So it should be replaced every 20 drum sets as I said before. For a quick clean, you don’t
need to take o-rings off. For a bigger, deeper clean, if you had a catastrophic gun problem, we want to pull off all the o-rings for a deeper, longer soak. We recommend that the gun be cleaned every day that it’s used. Some people clean their guns only once or twice every few weeks. When they do that, you
tend to have more stoppages and more wear on the o-rings. They tend to need repair more often. Every part gets dipped
in the solvent quickly and then back out, maybe give
it a blast of compressed air, and then every orifice
needs to get checked, regardless if it’s on the
head or the mix chamber or the side seals. You want to make everything is checked with an appropriate-size drill bit. Finally, we always put a
little white lithium grease on all the parts before we reassemble. Thanks for watching this video on cleaning your Fusion AP
