CAUTION
WARNING
* The most likely time to damage the nozzle (#1C) is upon removal from the airbrush. Because the head system can be removed entirely, the
nozzle does not need to be removed at all. If the nozzle is never removed, you do not have to worry about “improper nozzle to head nozzle
base connections”.
