I have an Aztek A320 airbrush and it always seems to be not working.
The recent problem is that when I put the red nozzle on to do a camo scheme nothing comes out of the airbrush. The paint is real thin, so that cant be the problem. Paint thinner doesn’t even come out of the airbrush when a bottle filled with it is attached. I use my grey nozzle and nothing comes out of there. Water doesn't even come out when I tried that.
I am getting to be very frustrated with it. Could you please help me? Thanks!

Chip:
Have the 2 nozzels been used before?
If they have that's probably your problem, I keep my nozzels submerged in thinner when not using them, that seems to keep them in working order. Others will take theirs apart and clean them. I aslo clean the inside of the brost (the front portion that the nozzel fits into) with a Q-tip after every use, after running water from the tap though the brush (meaning I hold it under the faucet and let the water run into the nozzel area and come out the small hole on the side)

Those nozzles are the joy and the bane of Aztek brushes. They say you are not supposed to remove the needle from the housing, but I do after every use, for cleaning. And, like Nate, I store my nozzles after cleaning submerged in thinner (Mineral Spirits, actually). If I don't, they clog up in a heartbeat.

After I heard about it here on ArmoramA I too started taking my nozzels apart, and I was suprised to see how much junk collects there.

To take them apart pull on the colored plastic bit that springs in and out. That removes the needle. To clean the needle better just carefully pull off the spring by holding the tightly coiled part at the bottom and pull. this way you wont stretch it out at all.
Right after I finish spraying I take the needle and spring assembly out and clean it. Then I clean out the housing with mineral spirits and install the housing (minus the needle assembly) in the airbrush and blast air through it blows clean. Then just rinse everything with clean water and you'll be on your way.

If it wont spray check if the needle is stuck. This recently happened to me. If so, just disassemble the nozzle, clean it up and try again. (worked for me!)

P.S. Does anyone else have a problem with spatter with you first depress the trigger? Its not a big deal for me but can be annoying in some cases.
