Iwata revolution CR problem

[OJDee]

Hi,

I have been using my airbrush for the last few months with no problem but now it seems as though it has developed a leak of sorts and I wondered if there was some adjustment internally that would fix it.

Original, with air but no paint set on the switch, nothing but air would come out of the nozzle. Now, however, even when I haven't pulled back at all on the switch, there is a small amount of pain being sprayed out of the nozzle.

I was wondering if this is a sign of wear on the needle or something like that, which would be disappointing since it is still pretty new, or something I can correct with adjustments inside?

Any help would be much appreciated.

Cheers
Oli

My guess is that you haven't pushed the needle tightly against the nozzle and that originates the leak. Also the screw that tights the needle to the lever should be quite tight. Check those items and tell us if the problem persist.

Cheers,
Pedro.

Its dirty. Take it all apart and soak the metal parts in lacquer thinner. Something isnt properly seated because of paint buildup.

I had a similar problem and found a small piece of metal was stuck in the air valve seat, causing it not to close all the way. The metal appeared to be a scrap from the manufacturing process. Cleaned it out and its been working fine since.

Cheers guys - I took it to pieces and wiped the needle down. I also think than maybe the needle wasn't being pushed forward as far as it needed to make a seal. Only in taking it apart to clean it did I take a closer look at the mechanism and tighten it all up. Works great now cheers.

these airbrushes are all mechanical parts, and sturdy parts at that. I've noticed that when something goes wrong, it usually is due to paint buildup. Sometimes when i've let the paint sit just a few minutes too long, it will barely spray, but I can turn up the airpressure very high (to around 40 PSI) and "blast" the paint through. I wouldn't recommend doing this too much, though, as it can really strain your compressor.

I think its a good idea to take apart your airbrush, slowly and carefully, when you first get it to understand how it works. That way when there is a problem you can narrow down what is happening.

First hand knowledge, eh?
