I suggest that you take the oiler off and leave it off as basically suggested by Flyboy. It doesn't take much oil (perhaps even the little bit that is left in the system upstream of the oiler as a result of blowback during compressor operation) to cause all sorts of paint problems, and the kinds of air tools used by a homeowner and hobbyist only need manual oiling before even a full day of virtually continuous use - per the instructions on my air tools.
