Hi, I am trying to service the oil in my pneumatic pump on my Yak, SteadFast. It is a 3 cylinder type usd for Gun charging I am told. It says to use Spec# AN-0-4
or AAF3600.
Anyone have a replacement for these or know thier Equal?
Thanks

Will,I used air tool oil in my CJ6. Just like any pneumatic tool you don't need much, just a little at annual. I would also put a few drops in the compressor from time to time also. flew it 450hrs in 5 years with no problems. I drained the water traps religiously every flight. Also clean the drier every 50hrs or so. Don
