919.162120 Regulator valve knob and Drain screw operation
by Handy Woman
I have a Craftsman 919.162120 oil-free air compressor which was given to me with no operation instructions.
I downloaded an owner's manual but it is woefully lacking in details.
My questions concern the regulator knob and drain valve/screw.. Turning the regulator knob as the instructions directed did not seem to release the pressure for drain down. I know it has to be pulled out to turn, but it didn't relieve the air pressure enough. After 15 minutes, I had to resort to using the safety valve.
Was this the right thing to do or am I not understanding how that regulator works?
Also, the winged drain screw seems to work opposite from "righty-tighty, lefty-loosey". It appears that when the screw is turned clockwise (righty-tighty) it is opening to drain. It seems to, but I would like some verification of the correct direction.
If there is a more detailed manual or video that I could look at, I would also appreciate that link.
