Hi Kent, I see no one has gotten to you so let me share with you some tips I got from Brad_bb. They helped me. Cleaning; "Adjusting a gun is relatively easy once you know what to look for. 1. Air pressure. Make sure your supply pressure is set at the factory recommended pressure. Now adjust the needle so that it allows you to squeeze the trigger fully. For the air adjustment on the gun, fill your cup partially with some lacquer thinner. Squeeze the trigger and adjust the air flow. Watch the spray coming out, you can see as you adjust the air flow when it is too much and forcing the thinner out and trying too hard- not smooth flow. Conversely when it's too low, it's not smooth either. You want to find that "happy place", and it's not that hard to do simply by looking at the flow and trying to get smooth, even flow. 2. adjusting the needle is simple. All you are doing is adjusting how much material can be allowed to flow. You are adjusting how far the trigger can be pulled. If you have a very thin paint material, set the trigger at the half way point. When you get more confidence and can control how fast you move the gun, you can start to use more trigger and move faster. On thicker materials you'll open up the trigger more. 3. the last adjustment is fan control. some guns have it, some don't. It just adjusts how big your spray pattern is from a small circle up the a large fan. Remember that when it's adjusted towards the smaller circular pattern, all that same material is going to be hitting a smaller spot so you have to move faster so you don't run or you have to reduce your trigger pull. the small patterin is used for getting into tight corners, whereas the large fan is used on larger, flatter panels. I would recommend that you NOT do any spraying in direct sun. It's going to heat up panels beyond the heat range for the material. Weather(moisture) should not affect the primer or paint you are using at all. Is your supply air clean and dry? Do you have a water trap, oil trap, and regulator on your supplied air? Do you Drain the water from your compressor tank regularly? I installed some pipe fittings and a ball valve on my compressor drain for easy draining. Temperature will have an effect if you are outside of the range for these products. I would always spray between 64 and 100F tops. At these extremes though, you should be using appropriate temperature range reducers(if the material calls for reducer). Cleaning the gun. Dissassemble the gun, I'm also referring to the cap, needle and seat. On my Sata, the air cap on front unscrews by hand, then a tool is used to unscrew the needle seat. It's the part that has the hole the needle tip sits into. also unscrew the needle adjustment knob and remove the needle and spring. Clean the needle itself. Inside the gun, material that wasn't flushed out can built up. get some little gun cleaning brushes and you may need a small awl to try and pick out some of that residue material. Use clean up grade lacquer thinner for gun cleaning. I buy it by the 5 gallon can at the paint store(about $30). I use an empty 5 gallon lacquer thinner can with a funnel to dump my waste. Solids settle to the bottom and I use the used solvent to start the burning pile. I also recommend using blue Nitrile gloves when handling solvent etc. Lacquer thinner will attack them, but not nearly as fast as latex gloves which will instantly dissolve." I've painted outside with no problem unless it is hot, then the paint dries before it flows out. Hope this helps you.
