Question
I have a master airbrush model s62 which is brand new. The problem i am having is the air flow is backing up into the paint bottle and not pulling out the paint. The air flow is ok coming out of nozzle. Please help,Thanks,Ron

Answer
Hi  Ron,
It may be the paint bottle.  Make sure the cap of the bottle has an unobstructed hole. I try to make them as large as possible. They  clog up often.

If the hole is either being covered up with part of your hand or finger, or there is a bit of paint covering it, that paint will not  come out. Does it bubble in the jar ?
If using acrylics they dry quickly inside the stems of the bottles as well.

Also, did you try first blowing just water with a bit of brush cleaner in it? If that worked then the airbrush is ok. So, if it only happens with that paint jar then that's your problem.
If all that checks out as normal then there could be an internal problem with the new  airbrush, it  happens, I had 2  Badger Crescendos that were made with internal flaws.
Hope that helps.
