See if your airbrush has an internal mix, if so it is run with a needle which has complete control over the flow of paint but make sure nothing happens to the needle as that could cause too much spraying variety. Do not allow the needle to become bent but if it does quickly replace it or have it straightened out.
Both the head assembly and air cap are located towards the very front and they encircle the needle tip. These two pieces control the paint spray atomization so if dents or other damages happen to them you must quickly replace these critical components. With any potential harm to these two parts comes a decrease in airbrush performance so you will find it next to impossible to control the airbrush as you wish. Finding replacement parts is simple because there are many hobby stores that carry these specific types of parts and usually have them in stock.
The all important trigger is the mechanism that starts the airbrush to work properly. Understand the trigger mechanism controls only the air flow with a single action airbrush but with a double action airbrush it also has control over the paint flow. If you are new to using an airbrush put in some trigger practice to be able to have more control over the airbrush. Know that there is a back lever that serves to close all air and paint flow once you have let go of the trigger. If the back lever is ever damaged you will be unable to use it properly but simply locate a replacement part and it should be up and running in no time.
Airbrushes have different kinds of handles, some are solid while others are built with an opening so it just depends on what is most comfortable for you. The handle with the opening enables you to make any adjustments to the needle when using a single action airbrush without having to take off the handle. Many professional airbrush users remove the handle for easy and quick access to potential blockage problems. You have the option to keep the handle on or to remove it during your creative airbrush art sessions.
Look closely at the airbrush threads that are part of the head assembly and are located in the area that the air brush attaches to the air hose. Avoid having these threads cross each other because you it may result in an unforeseen air leak. With any air leak the airbrush will be negatively effected and performance will go down so be aware of any potential crisscrossing of threads.
