Hello Everyone

Thanks for taking the time to read my post.
I have an Iwata HP-CH Airbrush and it is playing up on me.
When i press the lever down without pulling back paint come out
i have stripped and cleaned it yet it still happens?

Next is my Iwata smart jet pro compressor
when using is it starts to make unusual noises and starts to splutter
as though a car is running out of fuel.
Never used to do this.
Also people wondering i have had these for over 5 years but not hammered
or used all the time so out of warranty i should imagine.

Please could somebody help me

I don't know loads about airbrushes, used one for a little while but a long time ago.

If it's still doing it after a rebuild it might be that the needle is damaged or not closing of the nozzle correctly when the lever isn't being pulled back.

Or possibly there's a seal somewhere down the nozzle end of the airbrush that has perished so that the needle can't close the nozzle off.

Does the airbrush respond as you might expect if you do pull the level back - do you get more paint through, and is it in a uniform pattern?

The compressor, I haven't got a clue - sorry.

I don't know much about small compressors but have you checked the oil?

Did you remember to lubricate after cleaning and reassembly?

Check both the needle tip and the nozzle tip, both wear out and need to be replaced periodically.

Sounds like the needle isn't seating properly. Could be some gunk built up in the nozzle (the little brass part, that sits at the front end of the brush), and it's keeping the needle from forming an air-tight seal.

If you're sure it's clean, there could also be a crack in that nozzle as well. Or, the needle isn't pushed as far forward as it should be. Loosen the rear retaining nut, and LIGHTLY tap the needle back, on the table top, to make sure it's as far forward as possible. Hit it too hard, and you'll split the brass nozzle, up front.

As for the compressor, if it takes oil, make sure the level is good. If it's oil-less, it could be a hole in the air intake lines.
