I am guessing these are important steps to do. How important is it it to stick to the times on this list? In particular for the first time use as I have just received my spindle. We are looking at two and a half hours of running it the first time according to this.

Important. You’re warming up and seating the bearings. You should always run a warm-up routine first job if the day after breaking in the spindle to ensure maximum precision. You get tiny changes in things like runout as the bearings warm up and settle in.
