I have a ags300b27-er10 that I am cutting my teeth on right now so I can't tell you a whole lot about it. try to look up the om agsbb4 and imm ags-1 manuals. I just looked in my operation manual om agsb4 and found that the default low oil level delay is 120 sec. I wonder if the delay is from call for start up. anyways what kind of sensor is on the oil level?..
