Hf Airbrush Help

8 posts in this topic

I have the Harbor Freight 9581 Airbrush. The instructions arent so good. I get how the trigger works. You push it down to get airflow, then pull it back to get paint. There is a knurled collet near the back of the brush that seems to tighten on the really long pin. Is this an adjustment for something? Do I need to adjust the pins position for something?

This is called a dual action brush. On some you can adjust the collette to adjust the paint flow. When you pull back for paint it adjusts how much you can pull back. Its best to learn to control the paint flow before using that, then you'll find you use it very rarely. Also the "long pin" is called a "needle". You loosen the collette to remove the needle for cleaning. Be VERY careful, do not to bend the tip, and they are very sharp. When you change tip sizes ie, 2mm,3mm,5mm etc, you change the needle also. Be careful not to turn the gun upside down when the needle is out, the trigger will fall out. Hope this helps.

Thanks I had a Badger 250 but that is external mix and doesnt have a needle. It works differently. Sort of like a mini Stanley paint sprayer. It was very straightforward to use. Harbor Freight's instructions tell you nothing but not to spray it in your eye. LOL

If it's the same as on an Iwata, the rear nut is a needle stop, limiting how far back you can pull the trigger, and how much paint can be released. This may be a help if you are shooting details at low pressure.

I was just playing with it and when the needle is all the way in it doesnt let any paint out. I had to pull the needle out just a hair to get it to shoot paint. The instructions call it a needle chucking nut.

I had some success with that particular airbrush, but i found that i was wasting soo much paint from the siphon feed that i just returned it. i liked the gravity feed ones better. that one comes with a little cup that i thought would act like a gravity feed, but it hardly works. My cheap $20 ebay one has impressed me more than that one thus far.

But, to answer your post, ive always had the needle all the way to the tip and worked, so idk what's going on with yours. maybe a clot of some sort?

I took it apart to clean it and I see how it works. The needle has a tapered point which goes in to the back of the tip. This can probably be used to unclog it. In just playing around with it yesterday I found I get much more control than I had with the Badger 250. I think I could like this......

I have a harbor frieght dual airbrush and works great. The main thing is practice and patience. Ive learned to make very fine lines and im impressed with this airbrush compared to a gravity feed brush i bought from ebay.

Ive learned its not easy many factors involved. Paint viscocity and air pressure are two main things i struggled with in the beginning.
