I am not sure what you mean by "warming up". I do know that things that are computers they say to let them "warm up" before using them if they have been left in a cold environment.....was it cold where you are? I live were it can get well below zero on cold winter days....my long arm...I have to turn on and it helps to run it a bit without thread just to get it running nice and smooth....she is a bit rough for the first few minutes.....
