Iwata Eclipse Q.

Typically, with a dual action AB, you want to start with air and finish with air. With the dual action, the trigger controls both the air flow and the needle position. Press down to get air flowing through the brush and then pull back on the trigger - as it's depressed - to allow paint to flow. The farther you pull back on the trigger, the more the needle travels back and the more the nozzle opens up. By manipulating air (downward pressure on the trigger) and paint flow (rearward travel on the trigger) you can greatly control the amount of paint being applied to your project. It also helps to have a regulator on your compressor to limit the psi.

I'll check my Iwata instruction booklet to see if it says the same thing. I suspect it is a bad translation, as I would think that "pull back on the needle" means to pull back on the trigger. 

One of the nifty things about Iwatas is that if you're going to be doing a lot of fine line work, you can essentially make the brush a single action.

Loosen the needle retaining nut at the backend.  Press the trigger down for air and move the needle (with your free hand) until you're getting the spray pattern that you want.  Then retighten the nut.  Now all you have to do is push down on the trigger and you'll get consistently thin lines.

Now, is that what the instruction book was talking about?  Who knows, maybe it is just a bad case of "engrish", like Scrambler mentioned.  But either way, it's a cool little tip to make the Iwata just a bit more versatile.

Gigatron,

That is similar to what the manual says.

On page 8 under "fine line spray" it says start airflow,pull trigger back slightly to get paint flowing then "grip the exposed needle chucking nut (18) with fingers" then "pull backwhile depressing trigger".

I was just surprised you need to do that on a Dual action.But after your explaination i see it would be easier to do fine work,it would be more constant i suppose.
