Are there any unique maintenance steps for the Mobius 0.3mm airbrush? 

Yes. During deep cleaning, take extra care with the needle and nozzle components. After removing the air cap, nozzle cap, and nozzle, carefully remove the needle through the front of the airbrush. This helps prevent the needle tip from hitting internal components and reduces the chance of dragging paint residue into the trigger mechanism. Never force the needle during removal or reassembly. The Functional Cutaway Design can also be used to inspect and adjust trigger spring tension when needed.
