Does you HAAS have the programable coolant nozzles that point the coolant to the end of each tool no matter what the length, if so if memory serves right I did hear somewhere that there should be a built in delay in the control where the nozzles are set to the tools that can be toggled on/off/set, don`t know the age/level of your control so if yours is an early one it may not have that facility or I may have got it all wrong and it was a different make of machine !! (Playing the "age card" here )
