My compressor never came with an Owner's Manual, so maybe that's how they label the pressure release screw on the compressor side where fill whip attaches. My apologies never heard anything referred to as oil bleed screw but doesn't mean manufacturer didn't call it that. Filling tanks and guns is different, I can only share my SOP on filling guns. To repeat, at least for a second, I open each pressure release screw, one at a time, during the 3-5 minute fill time. I guess, if I ever picked up an SCBA tank, I'd maybe do the same, every 3-5 minutes during the longer fill time.
