Hi everyone. My query is the following, my painting machine instead of spraying the paint what it does is to release air through the tube from which it absorbs the paint. I have already completely disassembled it and it is perfectly clean without any obstructed conduit. The only thing I can think of is that the problem may be due to some orring of the needles. I hope you can help me, thank you very much. Greetings to all.
