FlyingSnowmew Posted April 20, 2010 Share Posted April 20, 2010 Are there any good guides online on how to troubleshoot an airbrush? I'm having some issues with mine and would be handy for future issues. Quote Link to post Share on other sites
FlyingSnowmew Posted April 21, 2010 Author Share Posted April 21, 2010 Thanks for the links! Right now I'm having issues of air bubbling into the cup and paint not spraying. I'm using an Iwata Eclipse. Quote Link to post Share on other sites
FlyingSnowmew Posted April 21, 2010 Author Share Posted April 21, 2010 I don't know Iwata,but sounds like a clogged nozzle. The air can't get out of the nozzle so it backs up into the cup. Have you cleaned it real well? It's brand new and the first time I've used it. Air seems to be flowing fine. I'll have to check it tomorrow. Quote Link to post Share on other sites
Bob Beary Posted April 21, 2010 Share Posted April 21, 2010 Check to see if the needle locking nut is tight (if it's not the needle won't move when you pull the trigger back) and that the paint is thin enough....go for skim milk consistency. Bob Quote Link to post Share on other sites
Don Wheeler Posted April 21, 2010 Share Posted April 21, 2010 Have a look here and see if it helps. Don Quote Link to post Share on other sites
little-cars Posted April 21, 2010 Share Posted April 21, 2010 (edited) On the Eclipse air can bubble back to the cup if the nozzle is not centred properly before the air cap/head is screwed into place. As it's a compression fit, any gaps at the base of the nozzle means that air will bubble back into the paint cup. I have seen this once on new brush, the paint nozzle was jammed solid in the front of the brush. Or it could be a split in the pointy end of the nozzle. or that the air cap/head isn't screwed on tight enough. This can also happen if the rubber has had a good soaking with an agresive airbrush cleaner. The o ring swells up and the head feels like it's on tight but isn't as the o ring is stopping it fitting properly. If you take it apart, check there isn't any damage on the front of the body of the airbrush or on the nozzle. If it is new, and isn't working correctly, contact the dealer that sold you the brush.

FlyingSnowmew Posted April 21, 2010 Author Share Posted April 21, 2010 It's still sputtering no matter what goes through it, whether it be the paint that came with the airbrush or the cleaner. I've lubed the needle and have tried adjusting it but still no luck. The needle and nozzle look fine under a magnifying glass and the o-ring seal seems to be fine.

terryt Posted April 22, 2010 Share Posted April 22, 2010 Check your head assembly and ensure it's tight. Iwata supplies a wrench to tighten and loosen the head. Don't tighten the head too much just snug it and try to spray again. Quote Link to post Share on other sites
