First let me apology for my bad English
My "Model Master Pro Airbrush" is been use only for one year (it was closed in a box for many years). All was fine till last week when I noticed that the trigger is going free and the airbrush is not spraying any paint.
The funny think is when the nozzle is removed from the airbrush...the trigger operate normally (I can feel the spring load. and when I reinstalling the nozzle back (tan) the trigger is not functioning normally.
I was cleaning my airbrush closely after each use ... did I missed something?
.
I live outside the USA and I don't think I'll be able to send back my airbrush to Aztek (very expansive).
Please any good advice from other Aztek users.
